XMPP Class

Properties   Methods   Events   Config Settings   Errors  

The XMPP Class is used to create a lightweight messaging client using the XMPP (Jabber) protocol.

Syntax

class ipworksiot.XMPP

Remarks

The XMPP class supports both plaintext and Secure Sockets Layer/Transport Layer Security (SSL/TLS) connections. When connecting over Secure Sockets Layer/Transport Layer Security (SSL/TLS) the on_ssl_server_authentication event allows you to check the server identity and other security attributes. The on_ssl_status event provides information about the SSL handshake. Additional SSL-related settings are also supported through the config method.

A call to the connect_to method will perform the entire logon process after which a on_connected event will fire to indicate the connection status. For simplicity, the entire interface is synchronous; the class will not return until a call is completed.

After a successful connection, the class will automatically begin the process of receiving the user's buddy list. The class will parse the XML as it comes in from the server and will set the appropriate properties. Once the entire buddy list has been retrieved, a on_sync event will fire.

Sending a message is as simple as calling a single method. One call to the send_message method will cause the class to connect if it has not already done so, send the specified message to a specified user, and return to the original connection state.

The XMPP Class interface supports messaging, list, and presence management. Other features of the XMPP protocol are supported through the send_command method and on_pi_trail event.

Example 1. Connecting and Sending a Message:

IMControl.ConnectTo("myusername", "mypassword") IMControl.MessageText = "My Message" IMControl.SendMessage("ToUser") Example 2. Sending a Single Message:

IMControl.User = "myusername" IMControl.Password = "mypassword" IMControl.MessageText = "My Message" IMControl.SendMessage("ToUser")

This property contains the name of the local host as obtained by the gethostname() system call, or if the user has assigned an IP address, the value of that address.

In multihomed hosts (machines with more than one IP interface) setting LocalHost to the IP address of an interface will make the class initiate connections (or accept in the case of server classs) only through that interface. It is recommended to provide an IP address rather than a hostname when setting this property to ensure the desired interface is used.

If the class is connected, the local_host property shows the IP address of the interface through which the connection is made in internet dotted format (aaa.bbb.ccc.ddd). In most cases, this is the address of the local host, except for multihomed hosts (machines with more than one IP interface).

presence Property

This property indicates the availability of the entity.

Syntax

def get_presence() -> int: ...

presence = property(get_presence, None)

Default Value

1

Remarks

When the class completes the initial login, it will send information telling other entities subscribed to this entity's presence that it is online.

The presence property has one of four values representing general information about the user's status as defined in the Jabber protocol specification:

pcOffline (0)Invisible: JabberId is offline.
pcChat (1)Available: JabberId is online.
pcAway (2)Away: JabberId is online, but the user is away from their computer.
pcXA (3)Extended Away: JabberId is online, but the user is away from their computer for an extended period of time.
pcDND (4)Do Not Disturb: JabberId is online, but is busy and does not wish to be disturbed.

By default, the class sets the client presence to pcChat, meaning that the user is available.

Note: Offline is not officially supported by the XMPP specification; however, some XMPP server implementations may recognize the value. Setting the client's presence state to this value may cause the server to respond with an on_error.

The status property is a pure-text string representing the user's presence information. Its value maybe be any random string, including the empty string, "".

If the application or user wishes to associate a specific status message with a new presence value, it should use the change_presence method. change_presence will update both the presence and status properties, and then send that information to the server.

This property is read-only.

The list_store_certificates method may be called after setting cert_store_type to cstPKCS11, cert_store_password to the PIN, and cert_store to the full path of the PKCS#11 DLL. The certificate information returned in the on_cert_list event's CertEncoded parameter may be saved for later use.

When using a certificate, pass the previously saved security key information as the ssl_accept_server_cert_store and set ssl_accept_server_cert_store_password to the PIN.

Code Example. SSH Authentication with Security Key: certmgr.CertStoreType = CertStoreTypes.cstPKCS11; certmgr.OnCertList += (s, e) => { secKeyBlob = e.CertEncoded; }; certmgr.CertStore = @"C:\Program Files\OpenSC Project\OpenSC\pkcs11\opensc-pkcs11.dll"; certmgr.CertStorePassword = "123456"; //PIN certmgr.ListStoreCertificates(); sftp.SSHCert = new Certificate(CertStoreTypes.cstPKCS11, secKeyBlob, "123456", "*"); sftp.SSHUser = "test"; sftp.SSHLogon("myhost", 22);

The certificate information returned in the on_cert_list event's CertEncoded parameter may be saved for later use.

When using a certificate, pass the previously saved security key information as the ssl_cert_store and set ssl_cert_store_password to the PIN.

Code Example. SSH Authentication with Security Key: certmgr.CertStoreType = CertStoreTypes.cstPKCS11; certmgr.OnCertList += (s, e) => { secKeyBlob = e.CertEncoded; }; certmgr.CertStore = @"C:\Program Files\OpenSC Project\OpenSC\pkcs11\opensc-pkcs11.dll"; certmgr.CertStorePassword = "123456"; //PIN certmgr.ListStoreCertificates(); sftp.SSHCert = new Certificate(CertStoreTypes.cstPKCS11, secKeyBlob, "123456", "*"); sftp.SSHUser = "test"; sftp.SSHLogon("myhost", 22);

"MY"

Remarks

The name of the certificate store for the client certificate.

The ssl_server_cert_store_type property denotes the type of the certificate store specified by ssl_server_cert_store. If the store is password-protected, specify the password in ssl_server_cert_store_password.

ssl_server_cert_store is used in conjunction with the ssl_server_cert_subject property to specify client certificates. If ssl_server_cert_store has a value, and ssl_server_cert_subject or ssl_server_cert_encoded is set, a search for a certificate is initiated. Please see the ssl_server_cert_subject property for details.

Designations of certificate stores are platform dependent.

The following designations are the most common User and Machine certificate stores in Windows:

MYA certificate store holding personal certificates with their associated private keys.
CACertifying authority certificates.
ROOTRoot certificates.

When the certificate store type is cstPFXFile, this property must be set to the name of the file. When the type is cstPFXBlob, the property must be set to the binary contents of a PFX file (i.e., PKCS#12 certificate store).

This property is read-only.

ssl_server_cert_store_password Property

If the type of certificate store requires a password, this property is used to specify the password needed to open the certificate store.

Syntax

def get_ssl_server_cert_store_password() -> str: ...

ssl_server_cert_store_password = property(get_ssl_server_cert_store_password, None)

Default Value

""

Remarks

If the type of certificate store requires a password, this property is used to specify the password needed to open the certificate store.

This property is read-only.

ssl_server_cert_store_type Property

ssl_server_cert_store_type = property(get_ssl_server_cert_store_type, None)

Default Value

0

Remarks

The type of certificate store for this certificate.

The class supports both public and private keys in a variety of formats. When the cstAuto value is used, the class will automatically determine the type. This property can take one of the following values:

0 (cstUser - default)For Windows, this specifies that the certificate store is a certificate store owned by the current user.

Note: This store type is not available in Java.

1 (cstMachine)For Windows, this specifies that the certificate store is a machine store.

Note: This store type is not available in Java.

2 (cstPFXFile)The certificate store is the name of a PFX (PKCS#12) file containing certificates.
3 (cstPFXBlob)The certificate store is a string (binary or Base64-encoded) representing a certificate store in PFX (PKCS#12) format.
4 (cstJKSFile)The certificate store is the name of a Java Key Store (JKS) file containing certificates.

Note: This store type is only available in Java.

5 (cstJKSBlob)The certificate store is a string (binary or Base64-encoded) representing a certificate store in Java Key Store (JKS) format.

Note: This store type is only available in Java.

6 (cstPEMKeyFile)The certificate store is the name of a PEM-encoded file that contains a private key and an optional certificate.
7 (cstPEMKeyBlob)The certificate store is a string (binary or Base64-encoded) that contains a private key and an optional certificate.

22 (cstBCFKSBlob)The certificate store is a string (binary or Base64-encoded) representing a certificate store in BCFKS (Bouncy Castle FIPS Key Store) format.

Note: This store type is only available in Java and .NET.

23 (cstPKCS11)The certificate is present on a physical security key accessible via a PKCS#11 interface.

To use a security key, the necessary data must first be collected using the CertMgr class. The list_store_certificates method may be called after setting cert_store_type to cstPKCS11, cert_store_password to the PIN, and cert_store to the full path of the PKCS#11 DLL. The certificate information returned in the on_cert_list event's CertEncoded parameter may be saved for later use.

When using a certificate, pass the previously saved security key information as the ssl_server_cert_store and set ssl_server_cert_store_password to the PIN.

Code Example. SSH Authentication with Security Key: certmgr.CertStoreType = CertStoreTypes.cstPKCS11; certmgr.OnCertList += (s, e) => { secKeyBlob = e.CertEncoded; }; certmgr.CertStore = @"C:\Program Files\OpenSC Project\OpenSC\pkcs11\opensc-pkcs11.dll"; certmgr.CertStorePassword = "123456"; //PIN certmgr.ListStoreCertificates(); sftp.SSHCert = new Certificate(CertStoreTypes.cstPKCS11, secKeyBlob, "123456", "*"); sftp.SSHUser = "test"; sftp.SSHLogon("myhost", 22);

def get_ssl_server_cert_subject() -> str: ...

ssl_server_cert_subject = property(get_ssl_server_cert_subject, None)

Default Value

""

Remarks

The subject of the certificate used for client authentication.

This property must be set after all other certificate properties are set. When this property is set, a search is performed in the current certificate store to locate a certificate with a matching subject.

If a matching certificate is found, the property is set to the full subject of the matching certificate.

If an exact match is not found, the store is searched for subjects containing the value of the property.

If a match is still not found, the property is set to an empty string, and no certificate is selected.

The special value "*" picks a random certificate in the certificate store.

The certificate subject is a comma-separated list of distinguished name fields and values. For instance, "CN=www.server.com, OU=test, C=US, E=support@nsoftware.com". Common fields and their meanings are as follows:

The certificate (PEM/Base64 encoded). This property is used to assign a specific certificate. The ssl_server_cert_store and ssl_server_cert_subject properties also may be used to specify a certificate.

When ssl_server_cert_encoded is set, a search is initiated in the current ssl_server_cert_store for the private key of the certificate. If the key is found, ssl_server_cert_subject is updated to reflect the full subject of the selected certificate; otherwise, ssl_server_cert_subject is set to an empty string.

This property is read-only.

ssl_start_mode Property

This property determines how the class starts the Secure Sockets Layer (SSL) negotiation.

Syntax

def get_ssl_start_mode() -> int: ...
def set_ssl_start_mode(value: int) -> None: ...

ssl_start_mode = property(get_ssl_start_mode, set_ssl_start_mode)

Default Value

3

Remarks

The ssl_start_mode property may have one of the following values:

0 (sslAutomatic)If the remote port is set to the standard plaintext port of the protocol (where applicable), the class will behave the same as if ssl_start_mode is set to sslExplicit. In all other cases, SSL negotiation will be implicit (sslImplicit).
1 (sslImplicit)The SSL negotiation will start immediately after the connection is established.
2 (sslExplicit)The class will first connect in plaintext, and then will explicitly start SSL negotiation through a protocol command such as STARTTLS.
3 (sslNone - default)No SSL negotiation; no SSL security. All communication will be in plaintext mode.

status Property

This property holds the description of the availability of this entity.

Syntax

def get_status() -> str: ...

status = property(get_status, None)

Default Value

"Available for Chat."

Remarks

When the class completes the initial login, it will send information telling other entities subscribed to this entity's presence that it is online.

The presence property has one of four values representing general information about the user's status as defined in the Jabber protocol specification:

pcOffline (0)Invisible: JabberId is offline.
pcChat (1)Available: JabberId is online.
pcAway (2)Away: JabberId is online, but the user is away from their computer.
pcXA (3)Extended Away: JabberId is online, but the user is away from their computer for an extended period of time.
pcDND (4)Do Not Disturb: JabberId is online, but is busy and does not wish to be disturbed.

By default, the class sets the client presence to pcChat, meaning that the user is available.

Note: Offline is not officially supported by the XMPP specification; however, some XMPP server implementations may recognize the value. Setting the client's presence state to this value may cause the server to respond with an on_error.

The status property is a pure-text string representing the user's presence information. Its value maybe be any random string, including the empty string, "".

If the application or user wishes to associate a specific status message with a new presence value, it should use the change_presence method. change_presence will update both the presence and status properties, and then send that information to the server.

This property is read-only.

timeout Property

The timeout for the class.

Syntax

def get_timeout() -> int: ...
def set_timeout(value: int) -> None: ...

timeout = property(get_timeout, set_timeout)

Default Value

60

Remarks

If the timeout property is set to 0, all operations will run uninterrupted until successful completion or an error condition is encountered.

If timeout is set to a positive value, the class will wait for the operation to complete before returning control.

The class will use do_events to enter an efficient wait loop during any potential waiting period, making sure that all system events are processed immediately as they arrive. This ensures that the host application does not freeze and remains responsive.

If timeout expires, and the operation is not yet complete, the class fails with an error.

Note: By default, all timeouts are inactivity timeouts, that is, the timeout period is extended by timeout seconds when any amount of data is successfully sent or received.

The default value for the timeout property is 60 seconds.

user Property

This property includes the user portion of this entity's Jabber Id.

Syntax

def get_user() -> str: ...
def set_user(value: str) -> None: ...

user = property(get_user, set_user)

Default Value

""

Remarks

The user property is a unique username associated with this entity and is set at the time of registration under the field "user".

user_domain Property

This property gets or sets the domain value used for Jabber Ids.

Syntax

def get_user_domain() -> str: ...
def set_user_domain(value: str) -> None: ...

user_domain = property(get_user_domain, set_user_domain)

Default Value

""

Remarks

A Jabber Id (JID) is a unique identifier of the format "user@domain/resource". user@domain denotes the account by username and domain. The resource is given during the login process to distinguish individual connections under the same account. If the im_server contains multiple domains, this property setting allows the user to specify the domain under which to log in.

If domain is empty, the value in im_server is used by default when creating the client's JID.

user_info_count Property

The number of records in the UserInfo arrays.

Syntax

def get_user_info_count() -> int: ...
def set_user_info_count(value: int) -> None: ...

user_info_count = property(get_user_info_count, set_user_info_count)

Default Value

0

Remarks

This property controls the size of the following arrays:

The array indices start at 0 and end at user_info_count - 1.

user_info_field Property

This property includes the name of the current property necessary for registration.

Syntax

def get_user_info_field(field_index: int) -> str: ...
def set_user_info_field(field_index: int, value: str) -> None: ...

Default Value

""

Remarks

This property includes the name of the current property necessary for registration.

Before a registration can be attempted, the application should use the query_register method to poll the host to which the user wishes to register. This will gather all of the necessary fields that the user must send to the server and will populate the user_info properties accordingly. After a successful query, all entries in user_info values will be empty strings.

The possible registration fields are defined in the Jabber protocol specification, as follows:

instructionsSpecial instructions sent from the server.
usernameThe username to be associated with this account.
passwordThe initial password for this account.
nameThe user's name.
emailThe user's email address.
addressThe user's physical address.
cityThe user's city of residence.
stateThe user's state (for US citizens).
zipThe user's postal code (for US citizens).
phoneThe user's phone number.
URLThe user's website.
dateThe date of registration.
miscAny miscellaneous data.
textAny extra text (potentially for a personal bio).
removeSpecifies a request to unregister.

After the user has set all of the values in user_info, and added any extra fields they may wish to include in their registration, the application should make a call to register.

If the class is not already connected when this method is called, it will connect, poll the registration fields, and then disconnect.

The field_index parameter specifies the index of the item in the array. The size of the array is controlled by the user_info_count property.

user_info_value Property

This property includes the value of the current registration property.

Syntax

def get_user_info_value(field_index: int) -> str: ...
def set_user_info_value(field_index: int, value: str) -> None: ...

Default Value

""

Remarks

This property includes the value of the current registration field. It should be set after calling query_register and before calling register.

Before a registration can be attempted, the application should use the query_register method to poll the host to which the user wishes to register. This will gather all of the necessary fields that the user must send to the server and will populate the user_info properties accordingly. After a successful query, all entries in user_info values will be empty strings.

The possible registration fields are defined in the Jabber protocol specification, as follows:

instructionsSpecial instructions sent from the server.
usernameThe username to be associated with this account.
passwordThe initial password for this account.
nameThe user's name.
emailThe user's email address.
addressThe user's physical address.
cityThe user's city of residence.
stateThe user's state (for US citizens).
zipThe user's postal code (for US citizens).
phoneThe user's phone number.
URLThe user's website.
dateThe date of registration.
miscAny miscellaneous data.
textAny extra text (potentially for a personal bio).
removeSpecifies a request to unregister.

After the user has set all of the values in user_info, and added any extra fields they may wish to include in their registration, the application should make a call to register.

If the class is not already connected when this method is called, it will connect, poll the registration fields, and then disconnect.

The field_index parameter specifies the index of the item in the array. The size of the array is controlled by the user_info_count property.

add Method

This method will add an entity to this entity's roster.

Syntax

def add(jabber_id: str, name: str, groups: str) -> None: ...

Remarks

JabberId is the Jabber Id of the entity to be added. It should be of form "user@host". If no hostname is specified, the class will assume the user's account is with the server in im_server, and will append that hostname to JabberId before sending the request.

Name will contain the name that is to be associated with JabberId in this entity's roster. It may be the empty string, "".

Groups is either the empty string ("") or a comma- separated list of groups to which the JabberId is to be added. If JabberId already exists in the buddy list, it will be updated to exist only in the specified groups. A buddy's group list can also be modified by the buddies property.

The add method will make a subscription request to the presence of the specified JabberId. Upon receiving this request, the server will add an entry into this user's buddy list with a subscription of type subscriptionNone (0) if there was no previous entry (if this user has already allowed JabberId to subscribe to this user's presence, there will already be an entry of type subscriptionFrom (2)). If the contact chooses to allow the subscription, the server will update the entry and a on_buddy_update event will fire with the new subscription value (subscriptionTo (1) if this is a new contact, or subscriptionBoth (3) if the contact is now mutual).

The XMPP protocol permits XMPP (Jabber) clients to communicate with foreign IM networks, such as AIM, MSN, SMS, and others, through the use of gateway servers that translate between the foreign protocol and XMPP. When sending or receiving presence information, messages, or subscription requests, Domain will be a gateway for the foreign network on which the contact resides and with which this user has registered an account for that foreign network. The register method can be used to register with a foreign network gateway.

cancel Method

This method will cancel another entity's subscription to this entity's presence.

Syntax

def cancel(jabber_id: str) -> None: ...

Remarks

If for any reason the user should want to undo a previously granted subscription, this can be achieved through the cancel method. The method will unsubscribe the target from this user's presence, thus preventing the target from seeing this user in the future.

change_password Method

This method will change the current user's password.

Syntax

def change_password(password: str) -> None: ...

Remarks

This method changes the current user's password to the password that is specified. The class must be connected to the server when this method is called.

change_presence Method

This method will set the availability and status of this entity.

Syntax

def change_presence(presence_code: int, status: str) -> None: ...

Remarks

PresenceCode should correspond to the possible values of the presence property:

pcOffline (0)Invisible: JabberId is offline.
pcChat (1)Available: JabberId is online.
pcAway (2)Away: JabberId is online, but the user is away from their computer.
pcXA (3)Extended Away: JabberId is online, but the user is away from their computer for an extended period of time.
pcDND (4)Do Not Disturb: JabberId is online, but is busy and does not wish to be disturbed.

By default, the class sets the client presence to pcChat, meaning that the user is available.

Note: Offline is not officially supported by the XMPP specification; however, some XMPP server implementations may recognize the value. Setting the client's presence state to this value may cause the server to respond with an on_error.

Status can be any random string, including the empty string "".

config Method

Sets or retrieves a configuration setting.

Syntax

def config(configuration_string: str) -> str: ...

Remarks

config is a generic method available in every class. It is used to set and retrieve configuration settings for the class.

These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the class, access to these internal properties is provided through the config method.

To set a configuration setting named PROPERTY, you must call Config("PROPERTY=VALUE"), where VALUE is the value of the setting expressed as a string. For boolean values, use the strings "True", "False", "0", "1", "Yes", or "No" (case does not matter).

To read (query) the value of a configuration setting, you must call Config("PROPERTY"). The value will be returned as a string.

connect Method

This method will connect the class to the server.

Syntax

def connect() -> None: ...

Remarks

The connect method performs the entire connection routine. This includes connection to the im_server, authenticating with the specified user and password, and session initialization.

The on_connected event will fire once for the initial Transmission Control Protocol (TCP) connection and again when the XMPP Logon is complete.

connect_to Method

This method will connect the class to the server.

Syntax

def connect_to(user: str, password: str) -> None: ...

Remarks

The connect_to method performs the entire connection routine. This includes connection to the im_server, user logon and authentication, and session initialization.

The on_connected event will fire once for the initial Transmission Control Protocol (TCP) connection and again when the XMPP Logon is complete.

Because connect_to is called with a user and password specified, the user and password properties will updated accordingly.

disconnect Method

This method disconnects the class from the server.

Syntax

def disconnect() -> None: ...

Remarks

The disconnect method will send the disconnect command to the notification server. Upon disconnection, a on_disconnected event will be fired.

do_events Method

This method processes events from the internal message queue.

Syntax

def do_events() -> None: ...

Remarks

When do_events is called, the class processes any available events. If no events are available, it waits for a preset period of time and then returns.

interrupt Method

This method interrupts the current method.

Syntax

def interrupt() -> None: ...

Remarks

If there is no method in progress, interrupt simply returns, doing nothing.

probe_presence Method

Use this method to probe for another entity's presence.

Syntax

def probe_presence(jabber_id: str) -> None: ...

Remarks

In the case that the user needs to update a particular entity's presence, this method can be used to retrieve it. After a successful call, the server will either respond with the last known presence for Jabber or will send a presence element of type "error". In either case, the respond will be returned by a on_presence event.

query_register Method

This method queries a server for the necessary registration fields.

Syntax

def query_register(xmpp_server: str) -> None: ...

Remarks

Before a registration can be attempted, the application should use the query_register method to poll the host to which the user wishes to register. This will gather all of the necessary fields that the user must send to the server and will populate the user_info properties accordingly. After a successful query, all entries in user_info values will be empty strings.

The possible registration fields are defined in the Jabber protocol specification, as follows:

instructionsSpecial instructions sent from the server.
usernameThe username to be associated with this account.
passwordThe initial password for this account.
nameThe user's name.
emailThe user's email address.
addressThe user's physical address.
cityThe user's city of residence.
stateThe user's state (for US citizens).
zipThe user's postal code (for US citizens).
phoneThe user's phone number.
URLThe user's website.
dateThe date of registration.
miscAny miscellaneous data.
textAny extra text (potentially for a personal bio).
removeSpecifies a request to unregister.

After the user has set all of the values in user_info, and added any extra fields they may wish to include in their registration, the application should make a call to register.

If the class is not already connected when this method is called, it will connect, poll the registration fields, and then disconnect.

register Method

This method registers an account with a server.

Syntax

def register(xmpp_server: str) -> None: ...

Remarks

Before a registration can be attempted, the application should use the query_register method to poll the host to which the user wishes to register. This will gather all of the necessary fields that the user must send to the server and will populate the user_info properties accordingly. After a successful query, all entries in user_info values will be empty strings.

The possible registration fields are defined in the Jabber protocol specification, as follows:

instructionsSpecial instructions sent from the server.
usernameThe username to be associated with this account.
passwordThe initial password for this account.
nameThe user's name.
emailThe user's email address.
addressThe user's physical address.
cityThe user's city of residence.
stateThe user's state (for US citizens).
zipThe user's postal code (for US citizens).
phoneThe user's phone number.
URLThe user's website.
dateThe date of registration.
miscAny miscellaneous data.
textAny extra text (potentially for a personal bio).
removeSpecifies a request to unregister.

After the user has set all of the values in user_info, and added any extra fields they may wish to include in their registration, the application should make a call to register.

If the class is not already connected when this method is called, it will connect, poll the registration fields, and then disconnect.

A new account can be registered at any time, including while the class is logged into the host under an existing account.

remove Method

This method will remove an entity from this entity's roster.

Syntax

def remove(jabber_id: str, name: str, group: str) -> None: ...

Remarks

JabberId is the Jabber Id of the entity to be removed. It should be in the form of "user@host". If no hostname is specified, the class will assume the user's account is with the server in im_server, and it will append that hostname to JabberId before sending the request.

Name should contain the name that is to be associated with JabberId in this entity's roster. It may be the empty string, "".

Groups may be either the empty string ("") or a comma- separated list of groups from which JabberId is to be removed. If no group is specified, the buddy will be completely removed from the buddy list.

After calling the remove method, the server will remove the entry from the server-side roster and will push the result out to all connected resources. A on_buddy_update event will fire with a subscription of type subscriptionRemove, and the entry will be removed from the Jabber class's internally stored list.

reset Method

This method will reset the class.

Syntax

def reset() -> None: ...

Remarks

This method will reset the class's properties to their default values.

retrieve_roster Method

This method will retrieve this entity's roster from the server.

Syntax

def retrieve_roster() -> None: ...

Remarks

After the class connects, it will automatically send a request to the server to retrieve the roster. If, however, the user or application wish to update the entire roster, this method may be used to do so.

After a successful call to the retrieve_roster method, the server will respond with this entity's roster. The class will parse the roster and fire the on_sync event once per item. This event may also fire for each entity added to or removed from the roster.

send_command Method

This method sends a command to the server.

Syntax

def send_command(command: str) -> None: ...

Remarks

The send_command method will send the Command parameter to the server. The command must be in valid XML format and must be recognizable to the im_server.

The send_command method should be used only by programmers or users who are connecting to nonstandard servers whose command list is not covered by the class. Any responses that are defined in the protocol specification will be returned by the appropriate event. Any nonstandard IQ message will be returned by the on_iq event. All other responses will be returned by the on_pi_trail event.

send_file Method

This method sends a file to the specified user.

Syntax

def send_file(jabber_id: str) -> None: ...

Remarks

This method sends the file specified by local_file to the user specified by the JabberId parameter.

JabberId is the intended recipient of the message. It is of the form user@domain/resource. If a resource is not supplied, all logged-in instances of the user's account will receive the message.

The class supports sending files using In-Band Bystestreams as defined in XEP-0047 and XEP-0096.

send_message Method

This method will send a message to the specified user.

Syntax

def send_message(jabber_id: str) -> str: ...

Remarks

JabberId is the intended recipient of the message. It is of the form user@domain/resource. If a resource is not supplied, all logged-in instances of the user's account will receive the message.

The class associates several properties with messages it receives and sends. When it receives a message, the class will parse out the corresponding values and set these properties before firing a on_message_in event. After the event returns control to the class, the properties will be cleared (i.e., they will be set to the empty string, "").

Before sending a message, the application should set the appropriate properties to be associated with the message. The class will send only properties with nonempty string values ("") and will clear all properties after a successful send.

The associated properties are the following:

message_typeThe type of message to be sent.
message_subjectFor "headline" type messages, this is the subject.
message_threadFor "chat" type messages, this is the thread on which the current message is a follow-up.
message_textThe plaintext of the message.
message_htmlThe HTML version of the message.
message_other_dataAny extra data associated with the message but not required by the protocol.

If the parameter passed to send_message is prefixed with "@" the component will interpret the value as a domain when constructing the message. This allows for sending directly to subdomains.

Note: The XMPP class will generate and return a unique identifier for each message sent. This identifier can be used to track messages in conjunction with various Jabber Extension Protocols.

set_user_info_field Method

This method will add a user information field for registration.

Syntax

def set_user_info_field(field: str, value: str) -> None: ...

Remarks

This method will search through user_info for the field name in Field and set the corresponding value to Value. If the field was not previously contained in user_info, it will automatically be added.

Before a registration can be attempted, the application should use the query_register method to poll the host to which the user wishes to register. This will gather all of the necessary fields that the user must send to the server and will populate the user_info properties accordingly. After a successful query, all entries in user_info values will be empty strings.

The possible registration fields are defined in the Jabber protocol specification, as follows:

instructionsSpecial instructions sent from the server.
usernameThe username to be associated with this account.
passwordThe initial password for this account.
nameThe user's name.
emailThe user's email address.
addressThe user's physical address.
cityThe user's city of residence.
stateThe user's state (for US citizens).
zipThe user's postal code (for US citizens).
phoneThe user's phone number.
URLThe user's website.
dateThe date of registration.
miscAny miscellaneous data.
textAny extra text (potentially for a personal bio).
removeSpecifies a request to unregister.

After the user has set all of the values in user_info, and added any extra fields they may wish to include in their registration, the application should make a call to register.

If the class is not already connected when this method is called, it will connect, poll the registration fields, and then disconnect.

subscribe_to Method

Use this method to subscribe to another entity's presence.

Syntax

def subscribe_to(jabber_id: str) -> None: ...

Remarks

This method will send a request for a subscription to JabberId's presence. If the entity allows the subscription, a new item will be stored in the buddy list with the appropriate subscription type. Otherwise, no change will take place.

unregister Method

This method cancels an account with the host.

Syntax

def unregister() -> None: ...

Remarks

If the user or application wishes to terminate an account with the im_server it should make a call to this method. After a successful call, the account will be canceled and the class will be logged off the server, but not disconnected.

unsubscribe_to Method

This method will cancel a subscription to another entity's presence.

Syntax

def unsubscribe_to(jabber_id: str) -> None: ...

Remarks

This method will inform the server of the cancellation of a subscription to JabberId's presence. After a successful call, the subscription type of the associated buddy list item will be updated.

update_buddy_group Method

This method updates the buddy's associated groups.

Syntax

def update_buddy_group(buddy_index: int, group: str) -> None: ...

Remarks

This method updates the associated groups for the buddy specified by BuddyIndex.

After the on_sync event has fired, the buddy_group property is populated with a comma-separated list of groups for each buddy. To update the groups for a buddy, call this method with the buddy's index and the comma-separated list of groups the buddy should be associated with. Setting Group to an empty string ("") will cause the buddy to be completely disassociated from all groups.

on_buddy_update Event

This event is fired whenever a roster entry is updated.

Syntax

class XMPPBuddyUpdateEventParams(object):
  @property
  def buddy_idx() -> int: ...

# In class XMPP:
@property
def on_buddy_update() -> Callable[[XMPPBuddyUpdateEventParams], None]: ...
@on_buddy_update.setter
def on_buddy_update(event_hook: Callable[[XMPPBuddyUpdateEventParams], None]) -> None: ...

Remarks

The on_buddy_update event will fire whenever a new buddy list entry is added or an old entry is updated. The updated information can be retrieved through the buddies properties property. The BuddyIdx parameter of this event will be the index of that XMPPBuddy in the properties.

on_connected Event

This event is fired when a connection to the IM server is completed.

@property
def on_disconnected() -> Callable[[XMPPDisconnectedEventParams], None]: ...
@on_disconnected.setter
def on_disconnected(event_hook: Callable[[XMPPDisconnectedEventParams], None]) -> None: ...

Remarks

If the connection is broken normally, StatusCode is 0, and Description is "OK".

If the connection is broken for any other reason, StatusCode has the error code returned by the Transmission Control Protocol (TCP)/IP subsystem. Description contains a description of this code. The value of StatusCode is equal to the value of the TCP/IP error.

Please refer to the Error Codes section for more information.

on_end_transfer Event

This event is fired when a file transfer completes.

Syntax

class XMPPEndTransferEventParams(object):
  @property
  def direction() -> int: ...

  @property
  def file_id() -> str: ...

  @property
  def file_name() -> str: ...

  @property
  def success() -> bool: ...

# In class XMPP:
@property
def on_end_transfer() -> Callable[[XMPPEndTransferEventParams], None]: ...
@on_end_transfer.setter
def on_end_transfer(event_hook: Callable[[XMPPEndTransferEventParams], None]) -> None: ...

Remarks

When a file transfer completes, this event will fire.

The Direction parameter shows whether the client (0) or the server (1) is sending the data.

on_error Event

This event is fired when the server sends a protocol error message.

Syntax

class XMPPErrorEventParams(object):
  @property
  def error_code() -> int: ...

  @property
  def description() -> str: ...

# In class XMPP:
@property
def on_error() -> Callable[[XMPPErrorEventParams], None]: ...
@on_error.setter
def on_error(event_hook: Callable[[XMPPErrorEventParams], None]) -> None: ...

Remarks

This event is fired whenever there is a protocol error. ErrorCode will contain the error code string sent by the server. Description will contain the Xmpp class's interpretation of the code.

on_iq Event

This event is fired for IQ messages not normally supported by the class.

Syntax

class XMPPIQEventParams(object):
  @property
  def iq() -> str: ...

  @property
  def id() -> str: ...

  @property
  def from_() -> str: ...

  @property
  def iq_type() -> str: ...

  @property
  def ignore() -> bool: ...
  @ignore.setter
  def ignore(value) -> None: ...

# In class XMPP:
@property
def on_iq() -> Callable[[XMPPIQEventParams], None]: ...
@on_iq.setter
def on_iq(event_hook: Callable[[XMPPIQEventParams], None]) -> None: ...

Remarks

Some servers may wish to gather some data from the client in ways not specified by the XMPP RFC. This event will contain any IQ message that is not a part of the Jabber specification. The Iq parameter will contain an entire XML entity, and thus it will require both knowledge of XML and knowledge of the possible contents of the IQ message to parse. Id will contain the transaction Id of the IQ message. From will contain the sender's Jabber Id. IqType will have one of the following values:

"get"The IQ is requesting information from this XMPP client.
"set"The IQ is attempting to set a value.
"result"The IQ is a success response to a previous IQ.
"error"The IQ is an error response to a previous IQ.

Note: To respond to these IQs, you may use the send_command method.

on_message_in Event

This event is fired upon receipt of a message.

Syntax

class XMPPMessageInEventParams(object):
  @property
  def message_id() -> str: ...

  @property
  def from_() -> str: ...

  @property
  def domain() -> str: ...

  @property
  def resource() -> str: ...

  @property
  def message_type() -> int: ...

  @property
  def subject() -> str: ...

  @property
  def message_thread() -> str: ...

  @property
  def message_text() -> str: ...

  @property
  def message_html() -> str: ...

  @property
  def other() -> str: ...

# In class XMPP:
@property
def on_message_in() -> Callable[[XMPPMessageInEventParams], None]: ...
@on_message_in.setter
def on_message_in(event_hook: Callable[[XMPPMessageInEventParams], None]) -> None: ...

Remarks

When a message is received, the XMPP class will parse the sender's Jabber Id into the From, Domain, and Resource fields. These parameters can be used to track the exact instance of a user's account that originated the message.

MessageId can be used with Jabber extension protocols. The MessageText parameter is the plaintext portion of the message body. MessageHTML will contain any HTML from the message.

Type is the type of message received. See message_type for a list of possible values. For a message of type "headline", Subject will reflect the subject of the message. For a message of type "chat", Thread will report the conversation thread for which the current message is a follow-up.

Other will contain any extra data associated with the message but not defined by the XMPP-IM protocol.

on_pi_trail Event

This event is fired for all protocol messages.

Syntax

class XMPPPITrailEventParams(object):
  @property
  def direction() -> int: ...

  @property
  def pi() -> str: ...

# In class XMPP:
@property
def on_pi_trail() -> Callable[[XMPPPITrailEventParams], None]: ...
@on_pi_trail.setter
def on_pi_trail(event_hook: Callable[[XMPPPITrailEventParams], None]) -> None: ...

Remarks

The on_pi_trail event is useful for debugging purposes. It shows all the interactions between the client and the server, line by line.

SessionId will hold the session number that originated the PI. A value of 0 is reserved for all PI dealing with the im_server.

The direction parameter shows the originator of the message:

0 (Client)Pi originates from the client.
1 (Server)Pi originates from the server.
2 (Info)Pi is an informative message originating from within the class.

The Pi parameter contains the PI message.

on_presence Event

This event is fired when the presence of a subscribed entity changes.

Syntax

class XMPPPresenceEventParams(object):
  @property
  def user() -> str: ...

  @property
  def domain() -> str: ...

  @property
  def resource() -> str: ...

  @property
  def availability() -> int: ...

  @property
  def status() -> str: ...

# In class XMPP:
@property
def on_presence() -> Callable[[XMPPPresenceEventParams], None]: ...
@on_presence.setter
def on_presence(event_hook: Callable[[XMPPPresenceEventParams], None]) -> None: ...

Remarks

This event contains the availability and status information of a particular Jabber entity to whom this entity has a subscription.

Because a user can log in multiple times using the same account, the XMPP class will parse the user's Jabber Id into the User, Domain, and Resource parameters so that the client can easily track which instance of the account sent the presence.

The XMPP protocol permits XMPP (Jabber) clients to communicate with foreign IM networks, such as AIM, MSN, SMS, and others, through the use of gateway servers that translate between the foreign protocol and XMPP. When sending or receiving presence information, messages, or subscription requests, Domain will be a gateway for the foreign network on which the contact resides and with which this user has registered an account for that foreign network. The register method can be used to register with a foreign network gateway.

Availability corresponds to the presence property of the class, with the same possible values:

pcOffline (0)Invisible: JabberId is offline.
pcChat (1)Available: JabberId is online.
pcAway (2)Away: JabberId is online, but the user is away from their computer.
pcXA (3)Extended Away: JabberId is online, but the user is away from their computer for an extended period of time.
pcDND (4)Do Not Disturb: JabberId is online, but is busy and does not wish to be disturbed.

By default, the class sets the client presence to pcChat, meaning that the user is available.

Note: Offline is not officially supported by the XMPP specification; however, some XMPP server implementations may recognize the value. Setting the client's presence state to this value may cause the server to respond with an on_error.

Status corresponds to the status property. This value may be any random string, including the empty string, "".

on_ready_to_send Event

This event is fired when the class is ready to send data.

Syntax

class XMPPReadyToSendEventParams(object):
# In class XMPP:
@property
def on_ready_to_send() -> Callable[[XMPPReadyToSendEventParams], None]: ...
@on_ready_to_send.setter
def on_ready_to_send(event_hook: Callable[[XMPPReadyToSendEventParams], None]) -> None: ...

Remarks

The on_ready_to_send event indicates that the underlying Transmission Control Protocol (TCP)/IP subsystem is ready to accept data after a failed send_bytes. This event also is fired immediately after a connection to the remote host is established.

on_ssl_server_authentication Event

Fired after the server presents its certificate to the client.

Syntax

class XMPPSSLServerAuthenticationEventParams(object):
  @property
  def cert_encoded() -> bytes: ...

  @property
  def cert_subject() -> str: ...

  @property
  def cert_issuer() -> str: ...

  @property
  def status() -> str: ...

  @property
  def accept() -> bool: ...
  @accept.setter
  def accept(value) -> None: ...

# In class XMPP:
@property
def on_ssl_server_authentication() -> Callable[[XMPPSSLServerAuthenticationEventParams], None]: ...
@on_ssl_server_authentication.setter
def on_ssl_server_authentication(event_hook: Callable[[XMPPSSLServerAuthenticationEventParams], None]) -> None: ...

Remarks

During this event, the client can decide whether or not to continue with the connection process. The Accept parameter is a recommendation on whether to continue or close the connection. This is just a suggestion: application software must use its own logic to determine whether or not to continue.

When Accept is False, Status shows why the verification failed (otherwise, Status contains the string OK). If it is decided to continue, you can override and accept the certificate by setting the Accept parameter to True.

on_ssl_status Event

Fired when secure connection progress messages are available.

Syntax

class XMPPSSLStatusEventParams(object):
  @property
  def message() -> str: ...

# In class XMPP:
@property
def on_ssl_status() -> Callable[[XMPPSSLStatusEventParams], None]: ...
@on_ssl_status.setter
def on_ssl_status(event_hook: Callable[[XMPPSSLStatusEventParams], None]) -> None: ...

Remarks

The event is fired for informational and logging purposes only. This event tracks the progress of the connection.

on_start_transfer Event

This event is fired when a file transfer begins.

Syntax

class XMPPStartTransferEventParams(object):
  @property
  def direction() -> int: ...

  @property
  def file_id() -> str: ...

  @property
  def user() -> str: ...

  @property
  def domain() -> str: ...

  @property
  def resource() -> str: ...

  @property
  def file_name() -> str: ...
  @file_name.setter
  def file_name(value) -> None: ...

  @property
  def datetime() -> str: ...

  @property
  def size() -> int: ...

  @property
  def accept() -> bool: ...
  @accept.setter
  def accept(value) -> None: ...

# In class XMPP:
@property
def on_start_transfer() -> Callable[[XMPPStartTransferEventParams], None]: ...
@on_start_transfer.setter
def on_start_transfer(event_hook: Callable[[XMPPStartTransferEventParams], None]) -> None: ...

Remarks

When a file is received, the XMPP component will parse the sender's Jabber Id into the User, Domain, and Resource fields. The FileId and FileName parameters identify the current transfer. Within this event, you may override the FileName by setting the FileName parameter. At this time, you may also set local_directory if it is not already set.

When sending a file, the XMPP component will parse the receiver's Jabber Id into the User, Domain, and Resource fields.

The Direction parameter shows whether the client (0) or the server (1) is sending the data.

on_subscription_request Event

This event fires when a subscription request is received.

Syntax

class XMPPSubscriptionRequestEventParams(object):
  @property
  def from_() -> str: ...

  @property
  def domain() -> str: ...

  @property
  def accept() -> bool: ...
  @accept.setter
  def accept(value) -> None: ...

# In class XMPP:
@property
def on_subscription_request() -> Callable[[XMPPSubscriptionRequestEventParams], None]: ...
@on_subscription_request.setter
def on_subscription_request(event_hook: Callable[[XMPPSubscriptionRequestEventParams], None]) -> None: ...

Remarks

This event fires whenever another XMPP entity requests a subscription to this entity's presence. The XMPP class will parse the requesting entity's Jabber Id into the From and Domain parameters. It is not necessary to know which resource sent the request, because all instances of the requesting entity's account have access to the same roster.

Accept will initially be False, but setting it to True will cause the XMPP class to allow the remote subscription. Otherwise, the XMPP class will actively deny the subscription request.

on_sync Event

This event fires upon a complete information synchronization with the server.

Syntax

class XMPPSyncEventParams(object):
# In class XMPP:
@property
def on_sync() -> Callable[[XMPPSyncEventParams], None]: ...
@on_sync.setter
def on_sync(event_hook: Callable[[XMPPSyncEventParams], None]) -> None: ...

Remarks

The on_sync event will fire after each successful call to the retrieve_roster method. When the event fires, the buddy list, or roster, will be completely retrieved and the buddies properties will be filled out accordingly:

IdThe Jabber Ids associated with the buddies.
GroupThe group associated with each entry (if a buddy is in more than one group, they will have multiple entries in the buddy list).
SubscriptionThe subscription type for each buddy.

Note: Please refer to buddies properties property for more information.

on_transfer Event

This event is fired during file transfer.

Syntax

class XMPPTransferEventParams(object):
  @property
  def direction() -> int: ...

  @property
  def file_id() -> str: ...

  @property
  def file_name() -> str: ...

  @property
  def bytes_transferred() -> int: ...

  @property
  def percent_done() -> int: ...

  @property
  def text() -> bytes: ...

  @property
  def cancel() -> bool: ...
  @cancel.setter
  def cancel(value) -> None: ...

# In class XMPP:
@property
def on_transfer() -> Callable[[XMPPTransferEventParams], None]: ...
@on_transfer.setter
def on_transfer(event_hook: Callable[[XMPPTransferEventParams], None]) -> None: ...

Remarks

This event will fire when sending or receiving. One or more Transfer events are fired during file transfer.

The BytesTransferred parameter shows the number of bytes transferred since the beginning of the transfer.

Text contains the portion of the file data being delivered.

The Direction parameter shows whether the client (0) or the server (1) is sending the data.

The PercentDone parameter shows the progress of the transfer in the corresponding direction. If PercentDone cannot be calculated, the value will be -1.

The Direction parameter shows whether the client (0) or the server (1) is sending the data.

The PercentDone parameter shows the progress of the transfer in the corresponding direction. If PercentDone can not be calculated the value will be -1.

Note: Events are not re-entrant. Performing time-consuming operations within this event will prevent it from firing again in a timely manner and may affect overall performance.

XMPP Config Settings

The class accepts one or more of the following configuration settings. Configuration settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the class, access to these internal properties is provided through the config method.

XMPP Config Settings

AccessToken:   The OAuth access token used for authentication.

This configuration setting specifies the OAuth access token used during authentication. This can be used when connecting to Facebook or Windows Live Messenger.

BlockSize:   Specifies the block size for file transfers.

This configuration setting specifies the size in bytes of the block size used when sending files. The default value is 4096. Increasing this value may improve performance. However, some servers may not support larger block sizes.

ClientId:   The OAuth client Id used for authentication.

This configuration setting specifies the OAuth client Id used during authentication. This can be used when connecting to Facebook. Windows Live Messenger does not require this value.

MessageId:   Specifies the number used in the message Id.

The value that is then converted to hex and appended to the XMPPMessage Id.

MessageXML:   Returns the last root-level element received by the component.

This configuration setting returns the last root-level element received by the component. This could be a message, IQ, presence, or any other element type.

Overwrite:   Specifies whether or not to overwrite received files.

The default value of configuration setting is False. If set to True, the class will overwrite the existing files in local_directory if another file with the same name is received. This is applicable only when receiving file transfers.

ParseHTML:   Tells XMPP whether or not to parse MessageHTML when it's set.

If ParseHTML is True, the class will take any value sent to message_html, compute a plaintext version of the text, and put it into the message_text property.

RetrieveRoster:   Whether to automatically retrieve the roster when logging in.

When this configuration setting is set to True (default), the class will automatically retrieve the roster from the server when logging in. Setting this to False will cause the class to not request the roster, which can be useful when interacting with some nonstandard XMPP servers.

SendSubscriptionResponse:   Determines whether a response will be sent to a Subscription Request.

When this configuration setting is set to True, a response will be sent to a subscription request based on the Accept parameter value of the on_subscription_request event. When set to False, a response will not be sent. Therefore, a response can be created and sent using send_command outside of the on_subscription_request event. The default value is True.

UseCompression:   Specified whether or not stream compression is used.

The default value of this configuration setting is False. If set to True, the class will use stream compression when communicating with the im_server.

TCPClient Config Settings

ConnectionTimeout:   Sets a separate timeout value for establishing a connection.

When set, this configuration setting allows you to specify a different timeout value for establishing a connection. Otherwise, the class will use timeout for establishing a connection and transmitting/receiving data.

FirewallAutoDetect:   Tells the class whether or not to automatically detect and use firewall system settings, if available.

This configuration setting is provided for use by classs that do not directly expose Firewall properties.

FirewallHost:   Name or IP address of firewall (optional).

If a FirewallHost is given, requested connections will be authenticated through the specified firewall when connecting.

If the FirewallHost setting is set to a Domain Name, a DNS request is initiated. Upon successful termination of the request, the FirewallHost setting is set to the corresponding address. If the search is not successful, an error is returned.

Note: This setting is provided for use by classs that do not directly expose Firewall properties.

FirewallPassword:   Password to be used if authentication is to be used when connecting through the firewall.

If FirewallHost is specified, the FirewallUser and FirewallPassword settings are used to connect and authenticate to the given firewall. If the authentication fails, the class fails with an error.

Note: This setting is provided for use by classs that do not directly expose Firewall properties.

FirewallPort:   The TCP port for the FirewallHost;.

The FirewallPort is set automatically when FirewallType is set to a valid value.

Note: This configuration setting is provided for use by classs that do not directly expose Firewall properties.

FirewallType:   Determines the type of firewall to connect through.

Possible values are as follows:

0No firewall (default setting).
1Connect through a tunneling proxy. FirewallPort is set to 80.
2Connect through a SOCKS4 Proxy. FirewallPort is set to 1080.
3Connect through a SOCKS5 Proxy. FirewallPort is set to 1080.
10Connect through a SOCKS4A Proxy. FirewallPort is set to 1080.

Note: This setting is provided for use by classs that do not directly expose Firewall properties.

FirewallUser:   A user name if authentication is to be used connecting through a firewall.

If the FirewallHost is specified, the FirewallUser and FirewallPassword settings are used to connect and authenticate to the Firewall. If the authentication fails, the class fails with an error.

Note: This setting is provided for use by classs that do not directly expose Firewall properties.

KeepAliveInterval:   The retry interval, in milliseconds, to be used when a TCP keep-alive packet is sent and no response is received.

When set, TCPKeepAlive will automatically be set to True. A TCP keep-alive packet will be sent after a period of inactivity as defined by KeepAliveTime. If no acknowledgment is received from the remote host, the keep-alive packet will be sent again. This configuration setting specifies the interval at which the successive keep-alive packets are sent in milliseconds. This system default if this value is not specified here is 1 second.

Note: This value is not applicable in macOS.

KeepAliveTime:   The inactivity time in milliseconds before a TCP keep-alive packet is sent.

When set, TCPKeepAlive will automatically be set to True. By default, the operating system will determine the time a connection is idle before a Transmission Control Protocol (TCP) keep-alive packet is sent. This system default if this value is not specified here is 2 hours. In many cases, a shorter interval is more useful. Set this value to the desired interval in milliseconds.

Linger:   When set to True, connections are terminated gracefully.

This property controls how a connection is closed. The default is True.

In the case that Linger is True (default), two scenarios determine how long the connection will linger. In the first, if LingerTime is 0 (default), the system will attempt to send pending data for a connection until the default IP timeout expires.

In the second scenario, if LingerTime is a positive value, the system will attempt to send pending data until the specified LingerTime is reached. If this attempt fails, then the system will reset the connection.

The default behavior (which is also the default mode for stream sockets) might result in a long delay in closing the connection. Although the class returns control immediately, the system could hold system resources until all pending data are sent (even after your application closes).

Setting this property to False forces an immediate disconnection. If you know that the other side has received all the data you sent (e.g., by a client acknowledgment), setting this property to False might be the appropriate course of action.

LingerTime:   Time in seconds to have the connection linger.

LingerTime is the time, in seconds, the socket connection will linger. This value is 0 by default, which means it will use the default IP timeout.

LocalHost:   The name of the local host through which connections are initiated or accepted.

The local_host setting contains the name of the local host as obtained by the gethostname() system call, or if the user has assigned an IP address, the value of that address.

In multihomed hosts (machines with more than one IP interface), setting LocalHost to the value of an interface will make the class initiate connections (or accept in the case of server classs) only through that interface.

If the class is connected, the local_host setting shows the IP address of the interface through which the connection is made in internet dotted format (aaa.bbb.ccc.ddd). In most cases, this is the address of the local host, except for multihomed hosts (machines with more than one IP interface).

LocalPort:   The port in the local host where the class binds.

This configuration setting must be set before a connection is attempted. It instructs the class to bind to a specific port (or communication endpoint) in the local machine.

Setting this to 0 (default) enables the system to choose a port at random. The chosen port will be shown by local_port after the connection is established.

local_port cannot be changed once a connection is made. Any attempt to set this when a connection is active will generate an error.

This configuration setting is useful when trying to connect to services that require a trusted port on the client side. An example is the remote shell (rsh) service in UNIX systems.

MaxLineLength:   The maximum amount of data to accumulate when no EOL is found.

MaxLineLength is the size of an internal buffer, which holds received data while waiting for an eol string.

If an eol string is found in the input stream before MaxLineLength bytes are received, the on_data_in event is fired with the EOL parameter set to True, and the buffer is reset.

If no eol is found, and MaxLineLength bytes are accumulated in the buffer, the on_data_in event is fired with the EOL parameter set to False, and the buffer is reset.

The minimum value for MaxLineLength is 256 bytes. The default value is 2048 bytes.

MaxTransferRate:   The transfer rate limit in bytes per second.

This configuration setting can be used to throttle outbound TCP traffic. Set this to the number of bytes to be sent per second. By default, this is not set and there is no limit.

ProxyExceptionsList:   A semicolon separated list of hosts and IPs to bypass when using a proxy.

This configuration setting optionally specifies a semicolon-separated list of hostnames or IP addresses to bypass when a proxy is in use. When requests are made to hosts specified in this property, the proxy will not be used. For instance:

www.google.com;www.nsoftware.com

TCPKeepAlive:   Determines whether or not the keep alive socket option is enabled.

If set to True, the socket's keep-alive option is enabled and keep-alive packets will be sent periodically to maintain the connection. Set KeepAliveTime and KeepAliveInterval to configure the timing of the keep-alive packets.

Note: This value is not applicable in Java.

TcpNoDelay:   Whether or not to delay when sending packets.

When set to True, the socket will send all data that are ready to send at once. When set to False, the socket will send smaller buffered packets of data at small intervals. This is known as the Nagle algorithm.

By default, this configuration setting is set to False.

UseIPv6:   Whether to use IPv6.

When set to 0 (default), the class will use IPv4 exclusively. When set to 1, the class will use IPv6 exclusively. To instruct the class to prefer IPv6 addresses, but use IPv4 if IPv6 is not supported on the system, this setting should be set to 2. The default value is 0. Possible values are as follows:

0 IPv4 only
1 IPv6 only
2 IPv6 with IPv4 fallback

SSL Config Settings

LogSSLPackets:   Controls whether SSL packets are logged when using the internal security API.

When ssl_provider is set to Internal, this configuration setting controls whether Secure Sockets Layer (SSL) packets should be logged. By default, this configuration setting is False, as it is useful only for debugging purposes.

When enabled, SSL packet logs are output using the on_ssl_status event, which will fire each time an SSL packet is sent or received.

Enabling this configuration setting has no effect if ssl_provider is set to Platform.

OpenSSLCADir:   The path to a directory containing CA certificates.

This functionality is available only when the provider is OpenSSL.

The path set by this property should point to a directory containing CA certificates in PEM format. The files each contain one CA certificate. The files are looked up by the CA subject name hash value, which must hence be available. If more than one CA certificate with the same name hash value exist, the extension must be different (e.g., 9d66eef0.0, 9d66eef0.1). OpenSSL recommends the use of the c_rehash utility to create the necessary links. Please refer to the OpenSSL man page SSL_CTX_load_verify_locations(3) for details.

OpenSSLCAFile:   Name of the file containing the list of CA's trusted by your application.

This functionality is available only when the provider is OpenSSL.

The file set by this property should contain a list of CA certificates in PEM format. The file can contain several CA certificates identified by the following sequences:

-----BEGIN CERTIFICATE-----

... (CA certificate in base64 encoding) ...

-----END CERTIFICATE-----

Before, between, and after the certificate text is allowed, which can be used, for example, for descriptions of the certificates. Refer to the OpenSSL man page SSL_CTX_load_verify_locations(3) for details.

OpenSSLCipherList:   A string that controls the ciphers to be used by SSL.

This functionality is available only when the provider is OpenSSL.

The format of this string is described in the OpenSSL man page ciphers(1) section "CIPHER LIST FORMAT". Please refer to it for details. The default string "DEFAULT" is determined at compile time and is normally equivalent to "ALL:!ADH:RC4+RSA:+SSLv2:@STRENGTH".

OpenSSLPrngSeedData:   The data to seed the pseudo random number generator (PRNG).

This functionality is available only when the provider is OpenSSL.

By default, OpenSSL uses the device file "/dev/urandom" to seed the PRNG, and setting OpenSSLPrngSeedData is not required. If set, the string specified is used to seed the PRNG.

ReuseSSLSession:   Determines if the SSL session is reused.

If set to True, the class will reuse the context if and only if the following criteria are met:

  • The target host name is the same.
  • The system cache entry has not expired (default timeout is 10 hours).
  • The application process that calls the function is the same.
  • The logon session is the same.
  • The instance of the class is the same.

SSLCACertFilePaths:   The paths to CA certificate files on Unix/Linux.

This configuration setting specifies the paths on disk to CA certificate files on Unix/Linux.

The value is formatted as a list of paths separated by semicolons. The class will check for the existence of each file in the order specified. When a file is found, the CA certificates within the file will be loaded and used to determine the validity of server or client certificates.

The default value is as follows:

/etc/ssl/ca-bundle.pem;/etc/pki/tls/certs/ca-bundle.crt;/etc/ssl/certs/ca-certificates.crt;/etc/pki/tls/cacert.pem

SSLCACerts:   A newline separated list of CA certificates to be included when performing an SSL handshake.

When ssl_provider is set to Internal, this configuration setting specifies one or more CA certificates to be included with the ssl_cert property. Some servers or clients require the entire chain, including CA certificates, to be presented when performing SSL authentication. The value of this configuration setting is a newline-separated (CR/LF) list of certificates. For instance:

-----BEGIN CERTIFICATE-----
MIIEKzCCAxOgAwIBAgIRANTET4LIkxdH6P+CFIiHvTowDQYJKoZIhvcNAQELBQAw
... Intermediate Cert ...
eWHV5OW1K53o/atv59sOiW5K3crjFhsBOd5Q+cJJnU+SWinPKtANXMht+EDvYY2w
F0I1XhM+pKj7FjDr+XNj
-----END CERTIFICATE-----
\r \n
-----BEGIN CERTIFICATE-----

... Root Cert ...
d8q23djXZbVYiIfE9ebr4g3152BlVCHZ2GyPdjhIuLeH21VbT/dyEHHA
-----END CERTIFICATE-----

SSLCheckCRL:   Whether to check the Certificate Revocation List for the server certificate.

This configuration setting specifies whether the class will check the Certificate Revocation List (CRL) specified by the server certificate. If set to 1 or 2, the class will first obtain the list of CRL URLs from the server certificate's CRL distribution points extension. The class will then make HTTP requests to each CRL endpoint to check the validity of the server's certificate. If the certificate has been revoked or any other issues are found during validation the class fails with an error.

When set to 0 (default), the CRL check will not be performed by the class. When set to 1, it will attempt to perform the CRL check, but it will continue without an error if the server's certificate does not support CRL. When set to 2, it will perform the CRL check and will throw an error if CRL is not supported.

This configuration setting is supported only in the Java, C#, and C++ editions. In the C++ edition, it is supported only on Windows operating systems.

SSLCheckOCSP:   Whether to use OCSP to check the status of the server certificate.

This configuration setting specifies whether the class will use OCSP to check the validity of the server certificate. If set to 1 or 2, the class will first obtain the Online Certificate Status Protocol (OCSP) URL from the server certificate's OCSP extension. The class will then locate the issuing certificate and make an HTTP request to the OCSP endpoint to check the validity of the server's certificate. If the certificate has been revoked or any other issues are found during validation, the class fails with an error.

When set to 0 (default), the class will not perform an OCSP check. When set to 1, it will attempt to perform the OCSP check, but it will continue without an error if the server's certificate does not support OCSP. When set to 2, it will perform the OCSP check and will throw an error if OCSP is not supported.

This configuration setting is supported only in the Java, C#, and C++ editions. In the C++ edition, it is supported only on Windows operating systems.

SSLCipherStrength:   The minimum cipher strength used for bulk encryption.

This minimum cipher strength is largely dependent on the security modules installed on the system. If the cipher strength specified is not supported, an error will be returned when connections are initiated.

Note: This configuration setting contains the minimum cipher strength requested from the security library. The actual cipher strength used for the connection is shown by the on_ssl_status event.

Use this configuration setting with caution. Requesting a lower cipher strength than necessary could potentially cause serious security vulnerabilities in your application.

When the provider is OpenSSL, SSLCipherStrength is currently not supported. This functionality is instead made available through the OpenSSLCipherList configuration setting.

SSLClientCACerts:   A newline separated list of CA certificates to use during SSL client certificate validation.

This configuration setting is only applicable to server components (e.g., TCPServer) see SSLServerCACerts for client components (e.g., TCPClient). This setting can be used to optionally specify one or more CA certificates to be used when verifying the client certificate that is presented by the client during the SSL handshake when ssl_authenticate_clients is enabled. When verifying the client's certificate, the certificates trusted by the system will be used as part of the verification process. If the client's CA certificates are not installed to the trusted system store, they may be specified here so they are included when performing the verification process. This configuration setting should be set only if the client's CA certificates are not already trusted on the system and cannot be installed to the trusted system store.

The value of this configuration setting is a newline-separated (CR/LF) list of certificates. For instance:

-----BEGIN CERTIFICATE-----
MIIEKzCCAxOgAwIBAgIRANTET4LIkxdH6P+CFIiHvTowDQYJKoZIhvcNAQELBQAw
... Intermediate Cert ...
eWHV5OW1K53o/atv59sOiW5K3crjFhsBOd5Q+cJJnU+SWinPKtANXMht+EDvYY2w

... Root Cert ...
d8q23djXZbVYiIfE9ebr4g3152BlVCHZ2GyPdjhIuLeH21VbT/dyEHHA
-----END CERTIFICATE-----

SSLEnabledCipherSuites:   The cipher suite to be used in an SSL negotiation.

This configuration setting enables the cipher suites to be used in SSL negotiation.

By default, the enabled cipher suites will include all available ciphers ("*").

The special value "*" means that the class will pick all of the supported cipher suites. If SSLEnabledCipherSuites is set to any other value, only the specified cipher suites will be considered.

Multiple cipher suites are separated by semicolons.

Example values when ssl_provider is set to Platform include the following: obj.config("SSLEnabledCipherSuites=*"); obj.config("SSLEnabledCipherSuites=CALG_AES_256"); obj.config("SSLEnabledCipherSuites=CALG_AES_256;CALG_3DES"); Possible values when ssl_provider is set to Platform include the following:

When TLS 1.3 is negotiated (see SSLEnabledProtocols), only the following cipher suites are supported:

  • TLS_AES_256_GCM_SHA384
  • TLS_CHACHA20_POLY1305_SHA256
  • TLS_AES_128_GCM_SHA256

SSLEnabledCipherSuites is used together with SSLCipherStrength.

SSLEnabledProtocols:   Used to enable/disable the supported security protocols.

This configuration setting is used to enable or disable the supported security protocols.

Not all supported protocols are enabled by default. The default value is 4032 for client components, and 3072 for server components. To specify a combination of enabled protocol versions set this config to the binary OR of one or more of the following values:

TLS1.312288 (Hex 3000)
TLS1.23072 (Hex C00) (Default - Client and Server)
TLS1.1768 (Hex 300) (Default - Client)
TLS1 192 (Hex C0) (Default - Client)
SSL3 48 (Hex 30)
SSL2 12 (Hex 0C)

Note that only TLS 1.2 is enabled for server components that accept incoming connections. This adheres to industry standards to ensure a secure connection. Client components enable TLS 1.0, TLS 1.1, and TLS 1.2 by default and will negotiate the highest mutually supported version when connecting to a server, which should be TLS 1.2 in most cases.

SSLEnabledProtocols: Transport Layer Security (TLS) 1.3 Notes:

By default when TLS 1.3 is enabled, the class will use the internal TLS implementation when the ssl_provider is set to Automatic for all editions.

In editions that are designed to run on Windows, ssl_provider can be set to Platform to use the platform implementation instead of the internal implementation. When configured in this manner, please note that the platform provider is supported only on Windows 11/Windows Server 2022 and up. The default internal provider is available on all platforms and is not restricted to any specific OS version.

If set to 1 (Platform provider), please be aware of the following notes:

  • The platform provider is available only on Windows 11/Windows Server 2022 and up.
  • SSLEnabledCipherSuites and other similar SSL configuration settings are not supported.
  • If SSLEnabledProtocols includes both TLS 1.3 and TLS 1.2, these restrictions are still applicable even if TLS 1.2 is negotiated. Enabling TLS 1.3 with the platform provider changes the implementation used for all TLS versions.

SSLEnabledProtocols: SSL2 and SSL3 Notes:

SSL 2.0 and 3.0 are not supported by the class when the ssl_provider is set to internal. To use SSL 2.0 or SSL 3.0, the platform security API must have the protocols enabled and ssl_provider needs to be set to platform.

SSLEnableRenegotiation:   Whether the renegotiation_info SSL extension is supported.

This configuration setting specifies whether the renegotiation_info SSL extension will be used in the request when using the internal security API. This configuration setting is False by default, but it can be set to True to enable the extension.

This configuration setting is applicable only when ssl_provider is set to Internal.

SSLIncludeCertChain:   Whether the entire certificate chain is included in the SSLServerAuthentication event.

This configuration setting specifies whether the Encoded parameter of the on_ssl_server_authentication event contains the full certificate chain. By default this value is False and only the leaf certificate will be present in the Encoded parameter of the on_ssl_server_authentication event.

If set to True, all certificates returned by the server will be present in the Encoded parameter of the on_ssl_server_authentication event. This includes the leaf certificate, any intermediate certificate, and the root certificate.

SSLKeyLogFile:   The location of a file where per-session secrets are written for debugging purposes.

This configuration setting optionally specifies the full path to a file on disk where per-session secrets are stored for debugging purposes.

When set, the class will save the session secrets in the same format as the SSLKEYLOGFILE environment variable functionality used by most major browsers and tools, such as Chrome, Firefox, and cURL. This file can then be used in tools such as Wireshark to decrypt TLS traffic for debugging purposes. When writing to this file, the class will only append, it will not overwrite previous values.

Note: This configuration setting is applicable only when ssl_provider is set to Internal.

SSLNegotiatedCipher:   Returns the negotiated cipher suite.

This configuration setting returns the cipher suite negotiated during the SSL handshake.

Note: For server components (e.g., TCPServer), this is a per-connection configuration setting accessed by passing the ConnectionId. For example: server.Config("SSLNegotiatedCipher[connId]");

SSLNegotiatedCipherStrength:   Returns the negotiated cipher suite strength.

This configuration setting returns the strength of the cipher suite negotiated during the SSL handshake.

Note: For server components (e.g., TCPServer), this is a per-connection configuration setting accessed by passing the ConnectionId. For example: server.Config("SSLNegotiatedCipherStrength[connId]");

SSLNegotiatedCipherSuite:   Returns the negotiated cipher suite.

This configuration setting returns the cipher suite negotiated during the SSL handshake represented as a single string.

Note: For server components (e.g., TCPServer), this is a per-connection configuration setting accessed by passing the ConnectionId. For example: server.Config("SSLNegotiatedCipherSuite[connId]");

SSLNegotiatedKeyExchange:   Returns the negotiated key exchange algorithm.

This configuration setting returns the key exchange algorithm negotiated during the SSL handshake.

Note: For server components (e.g., TCPServer), this is a per-connection configuration setting accessed by passing the ConnectionId. For example: server.Config("SSLNegotiatedKeyExchange[connId]");

SSLNegotiatedKeyExchangeStrength:   Returns the negotiated key exchange algorithm strength.

This configuration setting returns the strength of the key exchange algorithm negotiated during the SSL handshake.

Note: For server components (e.g., TCPServer), this is a per-connection configuration setting accessed by passing the ConnectionId. For example: server.Config("SSLNegotiatedKeyExchangeStrength[connId]");

SSLNegotiatedVersion:   Returns the negotiated protocol version.

This configuration setting returns the protocol version negotiated during the SSL handshake.

Note: For server components (e.g., TCPServer), this is a per-connection configuration setting accessed by passing the ConnectionId. For example: server.Config("SSLNegotiatedVersion[connId]");

SSLSecurityFlags:   Flags that control certificate verification.

The following flags are defined (specified in hexadecimal notation). They can be ORed together to exclude multiple conditions:

0x00000001Ignore time validity status of certificate.
0x00000002Ignore time validity status of CTL.
0x00000004Ignore non-nested certificate times.
0x00000010Allow unknown certificate authority.
0x00000020Ignore wrong certificate usage.
0x00000100Ignore unknown certificate revocation status.
0x00000200Ignore unknown CTL signer revocation status.
0x00000400Ignore unknown certificate authority revocation status.
0x00000800Ignore unknown root revocation status.
0x00008000Allow test root certificate.
0x00004000Trust test root certificate.
0x80000000Ignore non-matching CN (certificate CN non-matching server name).

This functionality is currently not available when the provider is OpenSSL.

SSLServerCACerts:   A newline separated list of CA certificates to use during SSL server certificate validation.

This configuration setting is only used by client components (e.g., TCPClient) see SSLClientCACerts for server components (e.g., TCPServer). This configuration setting can be used to optionally specify one or more CA certificates to be used when connecting to the server and verifying the server certificate. When verifying the server's certificate, the certificates trusted by the system will be used as part of the verification process. If the server's CA certificates are not installed to the trusted system store, they may be specified here so they are included when performing the verification process. This configuration setting should be set only if the server's CA certificates are not already trusted on the system and cannot be installed to the trusted system store.

The value of this configuration setting is a newline-separated (CR/LF) list of certificates. For instance:

-----BEGIN CERTIFICATE-----
MIIEKzCCAxOgAwIBAgIRANTET4LIkxdH6P+CFIiHvTowDQYJKoZIhvcNAQELBQAw

-----END CERTIFICATE-----

TLS12SignatureAlgorithms:   Defines the allowed TLS 1.2 signature algorithms when SSLProvider is set to Internal.

This configuration setting specifies the allowed server certificate signature algorithms when ssl_provider is set to Internal and SSLEnabledProtocols is set to allow TLS 1.2.

When specified the class will verify that the server certificate signature algorithm is among the values specified in this configuration setting. If the server certificate signature algorithm is unsupported, the class fails with an error.

The format of this value is a comma-separated list of hash-signature combinations. For instance: component.SSLProvider = TCPClientSSLProviders.sslpInternal; component.Config("SSLEnabledProtocols=3072"); //TLS 1.2 component.Config("TLS12SignatureAlgorithms=sha256-rsa,sha256-dsa,sha1-rsa,sha1-dsa"); The default value for this configuration setting is sha512-ecdsa,sha512-rsa,sha512-dsa,sha384-ecdsa,sha384-rsa,sha384-dsa,sha256-ecdsa,sha256-rsa,sha256-dsa,sha224-ecdsa,sha224-rsa,sha224-dsa,sha1-ecdsa,sha1-rsa,sha1-dsa.

To not restrict the server's certificate signature algorithm, specify an empty string as the value for this configuration setting, which will cause the signature_algorithms TLS 1.2 extension to not be sent.

TLS12SupportedGroups:   The supported groups for ECC.

This configuration setting specifies a comma-separated list of named groups used in TLS 1.2 for ECC.

The default value is ecdhe_secp256r1,ecdhe_secp384r1,ecdhe_secp521r1.

When using TLS 1.2 and ssl_provider is set to Internal, the values refer to the supported groups for ECC. The following values are supported:

  • "ecdhe_secp256r1" (default)
  • "ecdhe_secp384r1" (default)
  • "ecdhe_secp521r1" (default)

TLS13KeyShareGroups:   The groups for which to pregenerate key shares.

This configuration setting specifies a comma-separated list of named groups used in TLS 1.3 for key exchange. The groups specified here will have key share data pregenerated locally before establishing a connection. This can prevent an additional roundtrip during the handshake if the group is supported by the server.

The default value is set to balance common supported groups and the computational resources required to generate key shares. As a result, only some groups are included by default in this configuration setting.

Note: All supported groups can always be used during the handshake even if not listed here, but if a group is used that is not present in this list, it will incur an additional roundtrip and time to generate the key share for that group.

In most cases, this configuration setting does not need to be modified. This should be modified only if there is a specific reason to do so.

The default value is ecdhe_x25519,ecdhe_secp256r1,ecdhe_secp384r1,ffdhe_2048,ffdhe_3072

The values are ordered from most preferred to least preferred. The following values are supported:

  • "ecdhe_x25519" (default)
  • "ecdhe_x448"
  • "ecdhe_secp256r1" (default)
  • "ecdhe_secp384r1" (default)
  • "ecdhe_secp521r1"
  • "ffdhe_2048" (default)
  • "ffdhe_3072" (default)
  • "ffdhe_4096"
  • "ffdhe_6144"
  • "ffdhe_8192"

TLS13SignatureAlgorithms:   The allowed certificate signature algorithms.

This configuration setting holds a comma-separated list of allowed signature algorithms. Possible values include the following:

  • "ed25519" (default)
  • "ed448" (default)
  • "ecdsa_secp256r1_sha256" (default)
  • "ecdsa_secp384r1_sha384" (default)
  • "ecdsa_secp521r1_sha512" (default)
  • "rsa_pkcs1_sha256" (default)
  • "rsa_pkcs1_sha384" (default)
  • "rsa_pkcs1_sha512" (default)
  • "rsa_pss_sha256" (default)
  • "rsa_pss_sha384" (default)
  • "rsa_pss_sha512" (default)
The default value is rsa_pss_sha256,rsa_pss_sha384,rsa_pss_sha512,rsa_pkcs1_sha256,rsa_pkcs1_sha384,rsa_pkcs1_sha512,ecdsa_secp256r1_sha256,ecdsa_secp384r1_sha384,ecdsa_secp521r1_sha512,ed25519,ed448. This configuration setting is applicable only when SSLEnabledProtocols includes TLS 1.3.
TLS13SupportedGroups:   The supported groups for (EC)DHE key exchange.

This configuration setting specifies a comma-separated list of named groups used in TLS 1.3 for key exchange. This configuration setting should be modified only if there is a specific reason to do so.

The default value is ecdhe_x25519,ecdhe_x448,ecdhe_secp256r1,ecdhe_secp384r1,ecdhe_secp521r1,ffdhe_2048,ffdhe_3072,ffdhe_4096,ffdhe_6144,ffdhe_8192

The values are ordered from most preferred to least preferred. The following values are supported:

  • "ecdhe_x25519" (default)
  • "ecdhe_x448" (default)
  • "ecdhe_secp256r1" (default)
  • "ecdhe_secp384r1" (default)
  • "ecdhe_secp521r1" (default)
  • "ffdhe_2048" (default)
  • "ffdhe_3072" (default)
  • "ffdhe_4096" (default)
  • "ffdhe_6144" (default)
  • "ffdhe_8192" (default)

Socket Config Settings

AbsoluteTimeout:   Determines whether timeouts are inactivity timeouts or absolute timeouts.

If AbsoluteTimeout is set to True, any method that does not complete within timeout seconds will be aborted. By default, AbsoluteTimeout is False, and the timeout is an inactivity timeout.

Note: This option is not valid for User Datagram Protocol (UDP) ports.

FirewallData:   Used to send extra data to the firewall.

When the firewall is a tunneling proxy, use this property to send custom (additional) headers to the firewall (e.g., headers for custom authentication schemes).

InBufferSize:   The size in bytes of the incoming queue of the socket.

This is the size of an internal queue in the Transmission Control Protocol (TCP)/IP stack. You can increase or decrease its size depending on the amount of data that you will be receiving. In some cases, increasing the value of the InBufferSize setting can provide significant improvements in performance.

Some TCP/IP implementations do not support variable buffer sizes. If that is the case, when the class is activated the InBufferSize reverts to its defined size. The same happens if you attempt to make it too large or too small.

OutBufferSize:   The size in bytes of the outgoing queue of the socket.

This is the size of an internal queue in the TCP/IP stack. You can increase or decrease its size depending on the amount of data that you will be sending. In some cases, increasing the value of the OutBufferSize setting can provide significant improvements in performance.

Some TCP/IP implementations do not support variable buffer sizes. If that is the case, when the class is activated the OutBufferSize reverts to its defined size. The same happens if you attempt to make it too large or too small.

Base Config Settings

BuildInfo:   Information about the product's build.

When queried, this setting will return a string containing information about the product's build.

LicenseInfo:   Information about the current license.

When queried, this setting will return a string containing information about the license this instance of a class is using. It will return the following information:

  • Product: The product the license is for.
  • Product Key: The key the license was generated from.
  • License Source: Where the license was found (e.g., RuntimeLicense, License File).
  • License Type: The type of license installed (e.g., Royalty Free, Single Server).
  • Last Valid Build: The last valid build number for which the license will work.
MaskSensitiveData:   Whether sensitive data is masked in log messages.

In certain circumstances it may be beneficial to mask sensitive data, like passwords, in log messages. Set this to True to mask sensitive data. The default is True.

This setting only works on these classes: AS3Receiver, AS3Sender, Atom, Client(3DS), FTP, FTPServer, IMAP, OFTPClient, SSHClient, SCP, Server(3DS), Sexec, SFTP, SFTPServer, SSHServer, TCPClient, TCPServer.

ProcessIdleEvents:   Whether the class uses its internal event loop to process events when the main thread is idle.

If set to False, the class will not fire internal idle events. Set this to False to use the class in a background thread on Mac OS. By default, this setting is True.

SelectWaitMillis:   The length of time in milliseconds the class will wait when DoEvents is called if there are no events to process.

If there are no events to process when do_events is called, the class will wait for the amount of time specified here before returning. The default value is 20.

UseFIPSCompliantAPI:   Tells the class whether or not to use FIPS certified APIs.

When set to True, the class will utilize the underlying operating system's certified APIs. Java editions, regardless of OS, utilize Bouncy Castle Federal Information Processing Standards (FIPS), while all other Windows editions make use of Microsoft security libraries.

FIPS mode can be enabled by setting the UseFIPSCompliantAPI configuration setting to True. This is a static setting that applies to all instances of all classes of the toolkit within the process. It is recommended to enable or disable this setting once before the component has been used to establish a connection. Enabling FIPS while an instance of the component is active and connected may result in unexpected behavior.

For more details, please see the FIPS 140-2 Compliance article.

Note: This setting is applicable only on Windows.

Note: Enabling FIPS compliance requires a special license; please contact sales@nsoftware.com for details.

UseInternalSecurityAPI:   Whether or not to use the system security libraries or an internal implementation.

When set to False, the class will use the system security libraries by default to perform cryptographic functions where applicable.

Setting this configuration setting to True tells the class to use the internal implementation instead of using the system security libraries.

On Windows, this setting is set to False by default. On Linux/macOS, this setting is set to True by default.

To use the system security libraries for Linux, OpenSSL support must be enabled. For more information on how to enable OpenSSL, please refer to the OpenSSL Notes section.
