SysLog Module

Properties   Methods   Events   Config Settings   Errors  

The Syslog module is used to send and receive network system log packets.

Syntax

IPWorks.Syslog

Remarks

The Syslog class implements a lightweight BSD syslog client as specified in RFC 3164 (UDP), RFC 5425 (SSL/TLS), and RFC 6587 (TCP). The class is used to send and receive BSD system network logging packets.

The first step in using the Syslog class is to set LocalHost and LocalPort to the interface and port on which the host will be receiving syslog packets, then set Active to True. For each packet, the class will parse the headers and message and fire a PacketIn event.

Active Property (SysLog Module)

Indicates whether the module is active.

Syntax

public var active: Bool {
  get {...}
  set {...}
}

@property (nonatomic,readwrite,assign,getter=active,setter=setActive:) BOOL active;

- (BOOL)active;
- (void)setActive :(BOOL)newActive;

Default Value

False

Remarks

This property indicates whether the class is currently active and can send or receive data.

Note: Use the Activate or Deactivate method to control whether the class is active.

LocalHost Property (SysLog Module)

The name of the local host or user-assigned IP interface through which connections are initiated or accepted.

Syntax

public var localHost: String {
  get {...}
  set {...}
}

@property (nonatomic,readwrite,assign,getter=localHost,setter=setLocalHost:) NSString* localHost;

- (NSString*)localHost;
- (void)setLocalHost :(NSString*)newLocalHost;

Default Value

""

Remarks

The LocalHost 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 multi-homed 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 LocalHost 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 multi-homed hosts (machines with more than one IP interface).

NOTE: LocalHost is not persistent. You must always set it in code, and never in the property window.

LocalPort Property (SysLog Module)

The port in the local host where Syslog binds.

Syntax

public var localPort: Int32 {
  get {...}
  set {...}
}

@property (nonatomic,readwrite,assign,getter=localPort,setter=setLocalPort:) int localPort;

- (int)localPort;
- (void)setLocalPort :(int)newLocalPort;

Default Value

514

Remarks

The LocalPort property must be set before Syslog is activated (Active is set to True). It instructs the class to bind to a specific port (or communication endpoint) in the local machine.

Setting it to 0 (default) enables the TCP/IP stack to choose a port at random. The chosen port will be shown by the LocalPort property after the connection is established.

LocalPort cannot be changed once the class is Active. Any attempt to set the LocalPort property when the class is Active will generate an error.

The LocalPort property is useful when trying to connect to services that require a trusted port in the client side.

RemoteHost Property (SysLog Module)

Sets a specific host for outgoing log packets.

Syntax

public var remoteHost: String {
  get {...}
  set {...}
}

@property (nonatomic,readwrite,assign,getter=remoteHost,setter=setRemoteHost:) NSString* remoteHost;

- (NSString*)remoteHost;
- (void)setRemoteHost :(NSString*)newRemoteHost;

Default Value

"255.255.255.255"

Remarks

When a call is made to the SendPacket method, the class will send it to whatever value is in RemoteHost. The default value is the broadcast address, "255.255.255.255".

RemotePort Property (SysLog Module)

Sets a specific port for outgoing log packets.

Syntax

public var remotePort: Int32 {
  get {...}
  set {...}
}

@property (nonatomic,readwrite,assign,getter=remotePort,setter=setRemotePort:) int remotePort;

- (int)remotePort;
- (void)setRemotePort :(int)newRemotePort;

Default Value

514

Remarks

When a call is made to the SendPacket method, the class will send to RemoteHost on RemotePort. The default value is 514, the standard port as defined in the BSD syslog RFC 3164.

SSLAcceptServerCertEncoded Property (SysLog Module)

This is the certificate (PEM/Base64 encoded).

Syntax

public var sslAcceptServerCertEncoded: String {
  get {...}
  set {...}
}

public var sslAcceptServerCertEncodedB: Data { get {...} set {...} }

@property (nonatomic,readwrite,assign,getter=SSLAcceptServerCertEncoded,setter=setSSLAcceptServerCertEncoded:) NSString* SSLAcceptServerCertEncoded;

- (NSString*)SSLAcceptServerCertEncoded;
- (void)setSSLAcceptServerCertEncoded :(NSString*)newSSLAcceptServerCertEncoded;

@property (nonatomic,readwrite,assign,getter=SSLAcceptServerCertEncodedB,setter=setSSLAcceptServerCertEncodedB:) NSData* SSLAcceptServerCertEncodedB;

- (NSData*)SSLAcceptServerCertEncodedB;
- (void)setSSLAcceptServerCertEncodedB :(NSData*)newSSLAcceptServerCertEncoded;

Default Value

""

Remarks

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

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

If an error occurs when setting this property an error will not be thrown. This property has a related method which will throw an error:

public func setSSLAcceptServerCertEncodedB(sslAcceptServerCertEncoded: Data) throws
public func setSSLAcceptServerCertEncoded(sslAcceptServerCertEncoded: String) throws

SSLAuthenticateClients Property (SysLog Module)

If set to True, the server asks the client(s) for a certificate.

Syntax

- (NSData*)SSLCertEncodedB;
- (void)setSSLCertEncodedB :(NSData*)newSSLCertEncoded;

Default Value

""

Remarks

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

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

If an error occurs when setting this property an error will not be thrown. This property has a related method which will throw an error:

public func setSSLCertEncodedB(sslCertEncoded: Data) throws
public func setSSLCertEncoded(sslCertEncoded: String) throws

- (void)setSSLCertStoreB :(NSData*)newSSLCertStore;

Default Value

"MY"

Remarks

This is the name of the certificate store for the client certificate.

The SSLCertStoreType property denotes the type of the certificate store specified by SSLCertStore. If the store is password protected, specify the password in SSLCertStorePassword.

SSLCertStore is used in conjunction with the SSLCertSubject property to specify client certificates. If SSLCertStore has a value, and SSLCertSubject or SSLCertEncoded is set, a search for a certificate is initiated. Please see the SSLCertSubject 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 PFXFile, this property must be set to the name of the file. When the type is PFXBlob, the property must be set to the binary contents of a PFX file (i.e., PKCS#12 certificate store).

SSLCertStorePassword Property (SysLog Module)

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

Syntax

public var sslCertStorePassword: String {
  get {...}
  set {...}
}

@property (nonatomic,readwrite,assign,getter=SSLCertStorePassword,setter=setSSLCertStorePassword:) NSString* SSLCertStorePassword;

- (NSString*)SSLCertStorePassword;

  get {...}
  set {...}
}

public enum SyslogSSLCertStoreTypes: Int32 { case cstUser = 0 case cstMachine = 1 case cstPFXFile = 2 case cstPFXBlob = 3 case cstJKSFile = 4 case cstJKSBlob = 5 case cstPEMKeyFile = 6 case cstPEMKeyBlob = 7 case cstPublicKeyFile = 8 case cstPublicKeyBlob = 9 case cstSSHPublicKeyBlob = 10 case cstP7BFile = 11 case cstP7BBlob = 12 case cstSSHPublicKeyFile = 13 case cstPPKFile = 14 case cstPPKBlob = 15 case cstXMLFile = 16 case cstXMLBlob = 17 case cstJWKFile = 18 case cstJWKBlob = 19 case cstSecurityKey = 20 case cstBCFKSFile = 21 case cstBCFKSBlob = 22 case cstPKCS11 = 23 case cstAuto = 99 }

@property (nonatomic,readwrite,assign,getter=SSLCertStoreType,setter=setSSLCertStoreType:) int SSLCertStoreType;

- (int)SSLCertStoreType;
- (void)setSSLCertStoreType :(int)newSSLCertStoreType;

Default Value

0

Remarks

This is 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.
8 (cstPublicKeyFile)The certificate store is the name of a file that contains a PEM- or DER-encoded public key certificate.
9 (cstPublicKeyBlob)The certificate store is a string (binary or Base64-encoded) that contains a PEM- or DER-encoded public key certificate.
10 (cstSSHPublicKeyBlob)The certificate store is a string (binary or Base64-encoded) that contains an SSH-style public key.
11 (cstP7BFile)The certificate store is the name of a PKCS#7 file containing certificates.
12 (cstP7BBlob)The certificate store is a string (binary) representing a certificate store in PKCS#7 format.

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

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 ListStoreCertificates method may be called after setting CertStoreType to cstPKCS11, CertStorePassword to the PIN, and CertStore to the full path of the PKCS#11 DLL. The certificate information returned in the CertList event's CertEncoded parameter may be saved for later use.

When using a certificate, pass the previously saved security key information as the SSLCertStore and set SSLCertStorePassword 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);

99 (cstAuto)The store type is automatically detected from the input data. This setting may be used with both public and private keys and can detect any of the supported formats automatically.

SSLCertSubject Property (SysLog Module)

This is the subject of the certificate used for client authentication.

Syntax

public var sslCertSubject: String {
  get {...}
  set {...}
}

@property (nonatomic,readwrite,assign,getter=SSLCertSubject,setter=setSSLCertSubject:) NSString* SSLCertSubject;

- (NSString*)SSLCertSubject;
- (void)setSSLCertSubject :(NSString*)newSSLCertSubject;

Default Value

""

Remarks

This is 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:

FieldMeaning
CNCommon Name. This is commonly a hostname like www.server.com.
OOrganization
OUOrganizational Unit
LLocality
SState
CCountry
EEmail Address

If a field value contains a comma, it must be quoted.

If an error occurs when setting this property an error will not be thrown. This property has a related method which will throw an error:

public func setSSLServerCertEncodedB(sslServerCertEncoded: Data) throws
public func setSSLServerCertEncoded(sslServerCertEncoded: String) throws

UseTCP Property (SysLog Module)

Whether to use TCP.

Syntax

public var useTCP: Bool {
  get {...}
  set {...}
}

@property (nonatomic,readwrite,assign,getter=useTCP,setter=setUseTCP:) BOOL useTCP;

- (BOOL)useTCP;
- (void)setUseTCP :(BOOL)newUseTCP;

Default Value

False

Remarks

This property specifies whether TCP is used. By default this proprety is False and UDP is used. When set to True TCP will be used as the underlying protocol.

When set to True the following additional settings are also applicable:

Activate Method (SysLog Module)

Enables sending and receiving of data.

Syntax

public func activate() throws -> Void
- (void)activate;

Remarks

This method enables sending and receiving of data. When called the class will create a communication endpoint (socket) which can be used for sending and receiving UDP messages. This method must be called before using the class to send and receive data.

If the UseConnection configuration setting is set to , then a local association (connection) to the remote host is also created.

Config Method (SysLog Module)

Sets or retrieves a configuration setting.

Syntax

public func config(configurationString: String) throws -> String
- (NSString*)config:(NSString*)configurationString;

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.

Deactivate Method (SysLog Module)

Disables sending and receive of data.

Syntax

public func deactivate() throws -> Void
- (void)deactivate;

Remarks

This method disables sending and receiving of data. When called the class will destroy the existing socket and disable data communications.

DoEvents Method (SysLog Module)

Processes events from the internal message queue.

Syntax

public func doEvents() throws -> Void
- (void)doEvents;

Remarks

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

Reset Method (SysLog Module)

Reset the component.

Syntax

public func reset() throws -> Void
- (void)reset;

Remarks

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

ResolveRemoteHost Method (SysLog Module)

Resolves the hostname in RemoteHost to an IP address.

Syntax

public func resolveRemoteHost() throws -> Void
- (void)resolveRemoteHost;

Remarks

This method resolves the hostname specified by RemoteHost to an IP address. The resolved value is available in the RemoteHost property after this method returns.

In most cases calling this method is not necessary, the class will resolve the hostname automatically when necessary. If DelayHostResolution is this method may be called to manually resolve RemoteHost if desired.

SendPacket Method (SysLog Module)

Send a log packet to RemoteHost .

Syntax

public func sendPacket(facility: Int32, severity: Int32, message: String) throws -> Void
- (void)sendPacket:(int)facility :(int)severity :(NSString*)message;

Remarks

System log packets are composed of three main sections, each of which can be broken down into two smaller pieces.

The first section is the PRI, which contains the originating Facility and Severity of the Message. Facility is a value from 0 to 23, with each value being a different part of the system:

0Kernel messages
1User-level messages
2Mail system
3System daemons
4Security/authorization messages
5Messages generated internally by syslogd
6Line printer subsystem
7Network news subsystem
8UUCP subsystem
9Clock daemon
10Security/authorization messages
11FTP daemon
12NTP subsystem
13Log audit
14Log alert
15Clock daemon
16Local use
17Local use
18Local use
19Local use
20Local use
21Local use
22Local use
23Local use

Severity is a value from 0 to 7 using the following convention:

0Emergency - the system is unusable
1Alert - action must be taken immediately
2Critical - critical conditions exist
3Error - error conditions exist
4Warning - warning conditions exist
5Notice - normal but significant condition
6Informational - informative message
7Debug - debug-level messages

The section sections contains a timestamp and hostname, both of which are automatically generated by the class. The third section is the Message itself.

Connected Event (SysLog Module)

Fired immediately after a connection completes (or fails).

Syntax

func onConnected(remoteAddress: String, remotePort: Int32, statusCode: Int32, description: String)
- (void)onConnected:(NSString*)remoteAddress :(int)remotePort :(int)statusCode :(NSString*)description;

Remarks

This event fires after a connection completes or fails.

StatusCode is the value returned by the system TCP/IP stack. This will be 0 if the connection was successful.

Description contains a human readable description of the status. This will be "OK" if the connection was successful.

RemoteAddress is the IP address of the remote host.

RemotePort is the port on the remote host.

ConnectionStatus Event (SysLog Module)

Fired to indicate changes in a connection state.

Syntax

func onConnectionStatus(connectionEvent: String, statusCode: Int32, description: String)
- (void)onConnectionStatus:(NSString*)connectionEvent :(int)statusCode :(NSString*)description;

Remarks

The ConnectionStatus event is fired when the connection state changes: for example, completion of a firewall or proxy connection or completion of a security handshake.

The ConnectionEvent parameter indicates the type of connection event. Values may include the following:

Firewall connection complete.
Secure Sockets Layer (SSL) or S/Shell handshake complete (where applicable).
Remote host connection complete.
Remote host disconnected.
SSL or S/Shell connection broken.
Firewall host disconnected.
StatusCode has the error code returned by the Transmission Control Protocol (TCP)/IP stack. Description contains a description of this code. The value of StatusCode is equal to the value of the error.

Disconnected Event (SysLog Module)

Fired when a connection is closed.

Syntax

func onDisconnected(remoteAddress: String, remotePort: Int32, statusCode: Int32, description: String)
- (void)onDisconnected:(NSString*)remoteAddress :(int)remotePort :(int)statusCode :(NSString*)description;

Remarks

This event fires when a connection is closed.

StatusCode is the value returned by the system TCP/IP stack. This will be 0 if the connection was successful.

Description contains a human readable description of the status. This will be "OK" if the connection was successful.

RemoteAddress is the IP address of the remote host.

RemotePort is the port on the remote host.

Error Event (SysLog Module)

Fired when information is available about errors during data delivery.

Syntax

func onError(errorCode: Int32, description: String)
- (void)onError:(int)errorCode :(NSString*)description;

Remarks

The Error event is fired in case of exceptional conditions during message processing. Normally the class .

The ErrorCode parameter contains an error code, and the Description parameter contains a textual description of the error. For a list of valid error codes and their descriptions, please refer to the Error Codes section.

PacketIn Event (SysLog Module)

Fires whenever a system log packet is received.

Syntax

func onPacketIn(facilityCode: Int32, facility: String, severityCode: Int32, severity: String, timestamp: String, hostname: String, message: String, conforms: Bool, packet: Data, sourceAddress: String, sourcePort: Int32)
- (void)onPacketIn:(int)facilityCode :(NSString*)facility :(int)severityCode :(NSString*)severity :(NSString*)timestamp :(NSString*)hostname :(NSString*)message :(BOOL)conforms :(NSData*)packet :(NSString*)sourceAddress :(int)sourcePort;

Remarks

System log packets are composed of three main sections, each of which can be broken down into two smaller pieces.

The first section is the PRI, which contains the originating FacilityCode and SeverityCode of the Message. FacilityCode is a value from 0 to 23, with each value being a different part of the system. Facility is a string representation of FacilityCode based on the following convention:

0Kernel messages
1User-level messages
2Mail system
3System daemons
4Security/authorization messages
5Messages generated internally by syslogd
6Line printer subsystem
7Network news subsystem
8UUCP subsystem
9Clock daemon
10Security/authorization messages
11FTP daemon
12NTP subsystem
13Log audit
14Log alert
15Clock daemon
16Local use
17Local use
18Local use
19Local use
20Local use
21Local use
22Local use
23Local use
SeverityCode is a value from 0 to 7. Severity is a string representation of SeverityCode using the following convention:
0Emergency - the system is unusable.
1Alert - action must be taken immediately.
2Critical - critical conditions exist.
3Error - error conditions exist.
4Warning - warning conditions exist.
5Notice - normal but significant condition.
6Informational - informative message.
7Debug - debug-level messages.

The second section contains the Timestamp and Hostname. Timestamp is a string that should conform to the standard structure "MMM DD, HH:MM:SS". The class will search for the Timestamp and verify that it conforms. If it conforms, the class will set Hostname, otherwise, everything after the PRI will be placed in Message.

If Conforms is TRUE, then the original syslog packet conforms to the syslog RFC and Timestamp, Hostname, and Message will all have valid values. Otherwise, you should parse the contents of Packet to verify the fields manually.

SourceAddress and SourcePort are the address and port from which Packet was sent. This can be an intermediate syslog server that is simply forwarding packets from the original host.

SSLClientAuthentication Event (SysLog Module)

Fired when the client presents its credentials to the server.

Syntax

func onSSLClientAuthentication(remoteAddress: String, remotePort: Int32, certEncoded: Data, certSubject: String, certIssuer: String, status: String, accept: inout Bool)
- (void)onSSLClientAuthentication:(NSString*)remoteAddress :(int)remotePort :(NSData*)certEncoded :(NSString*)certSubject :(NSString*)certIssuer :(NSString*)status :(int*)accept;

Remarks

This event fires when a client connects to the class and presents a certificate for authentication. 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 to continue or not.

When Accept is False, Status shows why the verification failed (otherwise, Status contains the string "OK").

RemoteAddress is the IP address of the connecting client.

RemotePort is the source port of the connecting client.

CertEncoded is the base64 encoded certificate presented by the client.

CertSubject is the subject of the certificate presented by the client.

CertIssuer is the subject of the issuer of the certificate presented by the client.

Status is the stauts of the certificate.

Accept defines whether the certificate is accepted.

SSLServerAuthentication Event (SysLog Module)

Fires when connecting to the server.

Syntax

func onSSLServerAuthentication(remoteAddress: String, remotePort: Int32, certEncoded: Data, certSubject: String, certIssuer: String, status: String, accept: inout Bool)
- (void)onSSLServerAuthentication:(NSString*)remoteAddress :(int)remotePort :(NSData*)certEncoded :(NSString*)certSubject :(NSString*)certIssuer :(NSString*)status :(int*)accept;

Remarks

This event is where the client can decide whether to continue with the connection process or not. 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 to continue or not.

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.

RemoteAddress is the IP address of the server.

RemotePort is the source port of the server.

CertEncoded is the base64 encoded certificate presented by the server.

CertSubject is the subject of the certificate presented by the server.

CertIssuer is the subject of the issuer of the certificate presented by the server.

Status is the stauts of the certificate.

Accept defines whether the certificate is accepted.

SSLStatus Event (SysLog Module)

Shows the progress of the secure connection.

Syntax

func onSSLStatus(remoteAddress: String, remotePort: Int32, message: String)
- (void)onSSLStatus:(NSString*)remoteAddress :(int)remotePort :(NSString*)message;

Remarks

The event is fired for informational and logging purposes only. It is used to track the progress of the connection.

RemoteAddress is the IP address of the remote machine.

RemotePort is the port of the remote machine.

Message is the log message.

0 (RFC 3164 - Default) Uses RFC 3164
1 (RFC 5424) Uses RFC 5424
This setting specifies which version of Syslog will be used.

Note: This setting should be set before setting any of the AppName, MsgId, ProcId

UDP Config Settings

CaptureIPPacketInfo:   Used to capture the packet information.

If this is set to true, the component will capture the IP packet information.

The default value for this setting is False.

Note: This setting is only available in Windows.

DelayHostResolution:   Whether the hostname is resolved when RemoteHost is set.

This setting specifies whether a hostname is resolved immediately when RemoteHost is set. If the class will resolve the hostname and the IP address will be present in the RemoteHost property. If , the hostname is not resolved until needed by the component when a method to connect or send data is called. If desired, ResolveRemoteHost may called to manually resolve the value in RemoteHost at any time.

The default value is .

DestinationAddress:   Used to get the destination address from the packet information.

If CaptureIPPacketInfo is set to true, then this will be populated with the packet's destination address when a packet is received. This information will be accessible in the DataIn event.

Note: This setting is only available in Windows.

DontFragment:   Used to set the Don't Fragment flag of outgoing packets.

When set to True, packets sent by the class will have the Don't Fragment flag set. The default value is False.

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

The LocalHost 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 multi-homed 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 LocalHost 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 multi-homed hosts (machines with more than one IP interface).

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

This 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 LocalPort after the connection is established.

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

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

MaxPacketSize:   The maximum length of the packets that can be received.

This setting specifies the maximum size of the datagrams that the class will accept without truncation.

QOSDSCPValue:   Used to specify an arbitrary QOS/DSCP setting (optional).

UseConnection must be True to use this setting. This option allows you to specify an arbitrary DSCP value between 0 and 63. The default is 0. When set to the default value the component will not set a DSCP value.

Note: This setting uses the qWAVE API is only available on Windows 7, Windows Server 2008 R2, and later.

QOSTrafficType:   Used to specify QOS/DSCP settings (optional).

UseConnection must be True to use this setting. You may specify either the text or integer values: BestEffort (0), Background (1), ExcellentEffort (2), AudioVideo (3), Voice (4), and Control (5).

Note: This setting uses the qWAVE API which is only available on Windows Vista and Windows Server 2008 or above.

Note: QOSTrafficType must be set before setting Active to true.

ShareLocalPort:   If set to True, allows more than one instance of the class to be active on the same local port.

This option must be set before the class is activated through the Active property or it will have no effect.

The default value for this setting is False.

UseConnection:   Determines whether to use a connected socket.

UseConnection specifies whether the class should use a connected socket or not. The connection is defined as an association in between the local address/port and the remote address/port. As such, this is not a connection in the traditional TCP sense. What it means is only that the class will send and receive data only to and from the specified destination.

The default value for this setting is False.

UseIPv6:   Whether or not to use IPv6.

By default, the component expects an IPv4 address for local and remote host properties, and will create an IPv4 socket. To use IPv6 instead, set this to True.

Socket Config Settings

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

If AbsoluteTimeout is set to True, any method which 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 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 TCP/IP stack. You can increase or decrease its size depending on the amount of data that you will be receiving. Increasing the value of the InBufferSize setting can provide significant improvements in performance in some cases.

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. Increasing the value of the OutBufferSize setting can provide significant improvements in performance in some cases.

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.

CodePage:   The system code page used for Unicode to Multibyte translations.

The default code page is Unicode UTF-8 (65001).

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.
MaskSensitive:   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 to mask sensitive data. The default is .

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.

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

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

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