IPDaemon Module
Properties Methods Events Configuration Settings Errors
The IPDaemon Module is a generic TCP server module based on an asynchronous, event-driven architecture. It is designed to balance the load between connections for a fast, powerful server.
Syntax
IPWorks.Ipdaemon
Remarks
The IPDaemon Class supports both plaintext and SSL/TLS connections. When connecting over SSL/TLS the SSLServerAuthentication event allows you to check the server identity and other security attributes. The SSLStatus event provides information about the SSL handshake. Additional SSL related settings are also supported via the Config method. The SSLCert properties are used to select a certificate for the server (please note that a valid certificate MUST be selected before the server can function).
IPDaemon is the server complement of IPPort (which is used to create client applications). They share a common design philosophy and interface. We expect you will find IPDaemon as easy to use as IPPort.
By default, each instance of IPDaemon can handle up to 1,000 simultaneous incoming connections (this number may be increased up to 100,000 or decreased to a lower value by using the MaxConnections configuration setting).
The connections are identified by a ConnectionId, an id generated by the component to identify each connection. This id is unique to each connection. IPDaemon's events also have ConnectionId as a parameter to identify the connection they relate to.
Our main goal in designing IPDaemon was to make it easy to use without sacrificing performance. The class has a minimum of properties, and six events: ConnectionRequest, Connected, DataIn, Disconnected, ReadyToSend, and Error.
IPDaemon can start to listen on a port by setting the Listening property to True. When a remote host asks for a connection, the ConnectionRequest event is fired. At that point, the connection can either be accepted or rejected. If the connection is accepted, a ConnectionId is assigned, and communication can start. From this point on, the operation is very similar to IPPort. Data is sent by assigning the data string to the DataToSend property. The address and port of the incoming connection can be found by querying the RemoteHost and RemotePort properties.
Note: Server components are designed to process events as they occur. To ensure events are processed in a timely manner DoEvents should be called in a loop after the server is started.

ConnectionBacklog Property (IPDaemon Module)
The maximum number of pending connections maintained by the TCP/IP subsystem.
Syntax
public var connectionBacklog: Int32 {
get {...}
set {...} }
@property (nonatomic,readwrite,assign,getter=connectionBacklog,setter=setConnectionBacklog:) int connectionBacklog; - (int)connectionBacklog; - (void)setConnectionBacklog :(int)newConnectionBacklog;
Default Value
5
Remarks
This property contains the maximum number of pending connections maintained by the TCP/IP subsystem. This value reflects the SOMAXCON option for the main listening socket. The default value for most systems is 5. You may set this property to a larger value if the server is expected to receive a large number of connections, and queuing them is desirable.
Connections Property (IPDaemon Module)
A collection of currently connected clients.
Syntax
public var connections: [String: Connection] {
get {...} }
@property (nonatomic,readonly,assign,getter=connectionCount) int connectionCount; - (int)connectionCount; - (BOOL)acceptData:(int)connectionId; - (void)setAcceptData:(int)connectionId :(BOOL)newAcceptData; - (int)bytesSent:(int)connectionId; - (BOOL)connected:(int)connectionId; - (void)setConnected:(int)connectionId :(BOOL)newConnected; - (NSString*)connectionId:(int)connectionId; - (NSString*)dataToSend:(int)connectionId; - (void)setDataToSend:(int)connectionId :(NSString*)newDataToSend; - (NSData*)dataToSendB:(int)connectionId; - (void)setDataToSendB:(int)connectionId :(NSData*)newDataToSend; - (NSString*)EOL:(int)connectionId; - (void)setEOL:(int)connectionId :(NSString*)newEOL; - (NSData*)EOLB:(int)connectionId; - (void)setEOLB:(int)connectionId :(NSData*)newEOL; - (int)idleTimeout:(int)connectionId; - (void)setIdleTimeout:(int)connectionId :(int)newIdleTimeout; - (NSString*)localAddress:(int)connectionId; - (BOOL)readyToSend:(int)connectionId; - (int)recordLength:(int)connectionId; - (void)setRecordLength:(int)connectionId :(int)newRecordLength; - (NSString*)remoteHost:(int)connectionId; - (int)remotePort:(int)connectionId; - (BOOL)singleLineMode:(int)connectionId; - (void)setSingleLineMode:(int)connectionId :(BOOL)newSingleLineMode; - (int)timeout:(int)connectionId; - (void)setTimeout:(int)connectionId :(int)newTimeout; - (NSString*)userData:(int)connectionId; - (void)setUserData:(int)connectionId :(NSString*)newUserData; - (NSData*)userDataB:(int)connectionId; - (void)setUserDataB:(int)connectionId :(NSData*)newUserData;
Default Value
3
Remarks
The SSLStartMode 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 SSLStartMode 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 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. |
DefaultEOL Property (IPDaemon Module)
A default EOL value to be used by incoming connections.
Syntax
public var defaultEOL: String {
get {...}
set {...} }
public var defaultEOLB: Data {
get {...}
set {...} }
@property (nonatomic,readwrite,assign,getter=defaultEOL,setter=setDefaultEOL:) NSString* defaultEOL; - (NSString*)defaultEOL; - (void)setDefaultEOL :(NSString*)newDefaultEOL; @property (nonatomic,readwrite,assign,getter=defaultEOLB,setter=setDefaultEOLB:) NSData* defaultEOLB; - (NSData*)defaultEOLB; - (void)setDefaultEOLB :(NSData*)newDefaultEOL;
Default Value
""
Remarks
This property contains a default End Of Line (EOL) value to be used by incoming connections. Once the class accepts and establishes an inbound connection, it will set that connection's EOL to the value in this property. By default, this value is empty (""), meaning that data will be fired as it is received.
DefaultIdleTimeout Property (IPDaemon Module)
The default idle timeout for inactive clients.
Syntax
public var defaultIdleTimeout: Int32 {
get {...}
set {...} }
@property (nonatomic,readwrite,assign,getter=defaultIdleTimeout,setter=setDefaultIdleTimeout:) int defaultIdleTimeout; - (int)defaultIdleTimeout; - (void)setDefaultIdleTimeout :(int)newDefaultIdleTimeout;
Default Value
0
Remarks
This property specifies the idle timeout (in seconds) for clients. When set to a positive value the class will disconnect idle clients after the specified timeout.
This only applies to clients that have not sent or received data within DefaultIdleTimeout seconds.
If set to 0 (default) no idle timeout is applied.
Note: DoEvents must be called in order for the class to check existing connections.
DefaultMaxLineLength Property (IPDaemon Module)
The default maximum line length value for inbound connections.
Syntax
public var defaultMaxLineLength: Int32 {
get {...}
set {...} }
@property (nonatomic,readwrite,assign,getter=defaultMaxLineLength,setter=setDefaultMaxLineLength:) int defaultMaxLineLength; - (int)defaultMaxLineLength; - (void)setDefaultMaxLineLength :(int)newDefaultMaxLineLength;
Default Value
2048
Remarks
This property controls the default size of an internal buffer which holds received data while waiting for an end-of-line (EOL) string.
The minimum value for this property is 256 bytes. The default value is 2048 bytes.
DefaultSingleLineMode Property (IPDaemon Module)
Tells the module whether or not to treat new connections as line-oriented.
Syntax
public var defaultSingleLineMode: Bool {
get {...}
set {...} }
@property (nonatomic,readwrite,assign,getter=defaultSingleLineMode,setter=setDefaultSingleLineMode:) BOOL defaultSingleLineMode; - (BOOL)defaultSingleLineMode; - (void)setDefaultSingleLineMode :(BOOL)newDefaultSingleLineMode;
Default Value
False
Remarks
This property instructs the component whether or not to treat newly established connections as line-oriented protocols. If this value is True, newly accepted connections will read the incoming data stream as lines separated by CRLF, CR, or LF, and will ignore the end of lines (EOLs).
DefaultTimeout Property (IPDaemon Module)
An initial timeout value to be used by incoming connections.
Syntax
public var defaultTimeout: Int32 {
get {...}
set {...} }
@property (nonatomic,readwrite,assign,getter=defaultTimeout,setter=setDefaultTimeout:) int defaultTimeout; - (int)defaultTimeout; - (void)setDefaultTimeout :(int)newDefaultTimeout;
Default Value
0
Remarks
This property is used by the class to set the operational timeout value of all inbound connections once they are established.
By default, the timeout is 0, meaning that all inbound connections will behave asynchronously.
KeepAlive Property (IPDaemon Module)
When True, KEEPALIVE packets are enabled (for long connections).
Syntax
public var keepAlive: Bool {
get {...}
set {...} }
@property (nonatomic,readwrite,assign,getter=keepAlive,setter=setKeepAlive:) BOOL keepAlive; - (BOOL)keepAlive; - (void)setKeepAlive :(BOOL)newKeepAlive;
Default Value
False
Remarks
This property enables the SO_KEEPALIVE option on the incoming connections. This option prevents long connections from timing out in case of inactivity.
Please note that system TCP/IP stack implementations are not required to support SO_KEEPALIVE.
This property is shared among incoming connections. When the property is set, the corresponding value is set for incoming connections as they are accepted. Existing connections are not modified.
Linger Property (IPDaemon Module)
When set to True, connections are terminated gracefully.
Syntax
public var linger: Bool {
get {...}
set {...} }
@property (nonatomic,readwrite,assign,getter=linger,setter=setLinger:) BOOL linger; - (BOOL)linger; - (void)setLinger :(BOOL)newLinger;
Default Value
True
Remarks
This property controls how a connection is closed. The default is True. In this case the connection is closed only after all the data is sent. Setting it to False forces an abrupt (hard) disconnection. Any data that was in the sending queue may be lost.
The default behavior (which is also the default mode for stream sockets) might result in an indefinite delay in closing the connection. Although the class returns control immediately, the system might indefinitely hold system resources until all pending data is sent (even after your application closes). This means that valuable system resources might be wasted.
Setting this property to False forces an immediate disconnection. If you know that the other side has received all the data you have sent (by a client acknowledgment, for example), setting this property to False might be the appropriate course of action.
This property is shared among incoming connections. When the property is set, the corresponding value is set for incoming connections as they are accepted. Existing connections are not modified.
Listening Property (IPDaemon Module)
If True, the module accepts incoming connections on LocalPort.
Syntax
public var listening: Bool {
get {...}
set {...} }
@property (nonatomic,readwrite,assign,getter=listening,setter=setListening:) BOOL listening; - (BOOL)listening; - (void)setListening :(BOOL)newListening;
Default Value
False
Remarks
Use this property to make the class 'listen' (accept connections) on the port specified by the LocalPort property. Setting this property to False will make the class stop listening (please note that this does not close any existing connections).
Note: It is recommended to use the StartListening or StopListening method instead of setting this property.
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 setListening(listening: Bool) throws
LocalHost Property (IPDaemon 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 (IPDaemon Module)
The TCP port in the local host where the module listens.
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
0
Remarks
This property must be set before the class can start listening. If its value is 0, then the TCP/IP subsystem picks a port number at random. The port number can be found by checking the value of this property after the class is listening (ie. after successfully assigning True to the Listening property).
The service port is not shared among servers so two classs cannot be listening on the same port at the same time.
SSLAuthenticateClients Property (IPDaemon Module)
If true, the server asks the client(s) for a certificate.
Syntax
public var sslAuthenticateClients: Bool {
get {...}
set {...} }
@property (nonatomic,readwrite,assign,getter=SSLAuthenticateClients,setter=setSSLAuthenticateClients:) BOOL SSLAuthenticateClients; - (BOOL)SSLAuthenticateClients; - (void)setSSLAuthenticateClients :(BOOL)newSSLAuthenticateClients;
Default Value
False
Remarks
This property is used in conjunction with the SSLClientAuthentication event. Please refer to the documentation of the SSLClientAuthentication event for details.
SSLCertEncoded Property (IPDaemon Module)
This is the certificate (PEM/base64 encoded).
Syntax
public var sslCertEncoded: String {
get {...}
set {...} }
public var sslCertEncodedB: Data {
get {...}
set {...} }
@property (nonatomic,readwrite,assign,getter=SSLCertEncoded,setter=setSSLCertEncoded:) NSString* SSLCertEncoded; - (NSString*)SSLCertEncoded; - (void)setSSLCertEncoded :(NSString*)newSSLCertEncoded; @property (nonatomic,readwrite,assign,getter=SSLCertEncodedB,setter=setSSLCertEncodedB:) NSData* SSLCertEncodedB; - (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
SSLCertStore Property (IPDaemon Module)
This is the name of the certificate store for the client certificate.
Syntax
public var sslCertStore: String {
get {...}
set {...} }
public var sslCertStoreB: Data {
get {...}
set {...} }
@property (nonatomic,readwrite,assign,getter=SSLCertStore,setter=setSSLCertStore:) NSString* SSLCertStore; - (NSString*)SSLCertStore; - (void)setSSLCertStore :(NSString*)newSSLCertStore; @property (nonatomic,readwrite,assign,getter=SSLCertStoreB,setter=setSSLCertStoreB:) NSData* SSLCertStoreB; - (NSData*)SSLCertStoreB; - (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 are designations of the most common User and Machine certificate stores in Windows:
MY | A certificate store holding personal certificates with their associated private keys. |
CA | Certifying authority certificates. |
ROOT | Root 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. PKCS12 certificate store).
SSLCertStorePassword Property (IPDaemon 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; - (void)setSSLCertStorePassword :(NSString*)newSSLCertStorePassword;
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.
SSLCertStoreType Property (IPDaemon Module)
This is the type of certificate store for this certificate.
Syntax
public var sslCertStoreType: IpdaemonSSLCertStoreTypes {
get {...}
set {...} }

@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. |

""
Remarks
This is the subject of the certificate used for client authentication.
This property must be set after all other certificate properites are set. When this property is set, a search is performed in the current certificate store certificate with 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 displayed below.
Field | Meaning |
CN | Common Name. This is commonly a host name like www.server.com. |
O | Organization |
OU | Organizational Unit |
L | Locality |
S | State |
C | Country |
E | Email 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 setSSLCertSubject(sslCertSubject: String) throws

Syntax
public var sslEnabled: Bool {
get {...}
set {...} }
@property (nonatomic,readwrite,assign,getter=SSLEnabled,setter=setSSLEnabled:) BOOL SSLEnabled; - (BOOL)SSLEnabled; - (void)setSSLEnabled :(BOOL)newSSLEnabled;
Default Value
False
Remarks
This setting specifies whether TLS/SSL is enabled in the class. When False (default) the class operates in plaintext mode. When True TLS/SSL is enabled.
TLS/SSL may also be enabled by setting SSLStartMode. Setting SSLStartMode will automatically update this property value.
SSLProvider Property (IPDaemon Module)
TBD.
Syntax
public var sslProvider: IpdaemonSSLProviders {
get {...}
set {...} }
public enum IpdaemonSSLProviders: Int32 { case sslpAutomatic = 0 case sslpPlatform = 1 case sslpInternal = 2 }
@property (nonatomic,readwrite,assign,getter=SSLProvider,setter=setSSLProvider:) int SSLProvider; - (int)SSLProvider; - (void)setSSLProvider :(int)newSSLProvider;
Default Value
0
Remarks
TBD.
SSLStartMode Property (IPDaemon Module)
Determines how the module starts the SSL negotiation.
Syntax
public var sslStartMode: IpdaemonSSLStartModes {
get {...}
set {...} }
public enum IpdaemonSSLStartModes: Int32 { case sslAutomatic = 0 case sslImplicit = 1 case sslExplicit = 2 case sslNone = 3 }
@property (nonatomic,readwrite,assign,getter=SSLStartMode,setter=setSSLStartMode:) int SSLStartMode; - (int)SSLStartMode; - (void)setSSLStartMode :(int)newSSLStartMode;
Default Value
3
Remarks
The SSLStartMode 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 SSLStartMode 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 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. |
ChangeRecordLength Method (IPDaemon Module)
Changes the length of received data records.
Syntax
- (void)changeRecordLength:(int)connectionId :(int)recordLength;
Remarks
This method defines the length of data records to be received (in bytes) for the specified ConnectionId.
If RecordLength is set to a positive value, the class will accumulate data until RecordLength bytes of data is received and only then fire the DataIn event with data of length RecordLength. This allows data to be received as records of known length. This method can be called at any time to change the record length, including within the DataIn event.
A value of 0 (default) means this functionality is not used.
Config Method (IPDaemon Module)
Sets or retrieves a configuration setting.
Syntax
- (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.

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.
Interrupt Method (IPDaemon Module)
Interrupts a synchronous send to the remote host.
Syntax
Remarks
This property is called using the Connection Id if you wish to interrupt a connection and stop a file from uploading without disconnecting the client connected to the class. If you use SendFile to upload a file, the class will run synchronously on that Connection Id until it is completed.
PauseData Method (IPDaemon Module)
Pauses data reception.
Syntax
Remarks
This method pauses data reception for the connection identified by ConnectionId when called. While data reception is paused the DataIn event will not fire for the specified connection. Call ProcessData to re-enable data reception.
ProcessData Method (IPDaemon Module)
Re-enables data reception after a call to PauseData .
Syntax
Remarks
This method re-enables data reception for the connection identified by ConnectionId after a previous call to PauseData. When PauseData is called the DataIn event will not fire for the specified connection. To re-enable data reception and allow DataIn to fire call this method.
Note: This method is only used after previously calling PauseData. It does not need to be called to process incoming data by default.
Reset Method (IPDaemon 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.
Send Method (IPDaemon Module)
Sends binary data to the specified client.
Syntax
- (void)send:(int)connectionId :(NSData*)text;
Remarks
This method sends binary data to the client identified by ConnectionId. To send text use the SendText method instead.
When ConnectionsTimeout is set to 0 the class will behave asynchronously. If you are sending data to the remote host faster than it can process it, or faster than the network's bandwidth allows, the outgoing queue might fill up. When this happens, the operation The BytesSent property shows how many bytes were sent (if any). If 0 bytes were sent, then you can wait for the ReadyToSend event before attempting to send data again. (However, please note that ReadyToSend is not fired when part of the data is successfully sent).
SendBytes Method (IPDaemon Module)
Sends binary data to the specified client.
Syntax
- (void)sendBytes:(int)connectionId :(NSData*)data;
Remarks
This method sends binary data to the client identified by ConnectionId. To send text use the SendText method instead.
When ConnectionsTimeout is set to 0 the class will behave asynchronously. If you are sending data to the remote host faster than it can process it, or faster than the network's bandwidth allows, the outgoing queue might fill up. When this happens, the operation The BytesSent property shows how many bytes were sent (if any). If 0 bytes were sent, then you can wait for the ReadyToSend event before attempting to send data again. (However, please note that ReadyToSend is not fired when part of the data is successfully sent).

When ConnectionsTimeout is set to 0 the class will behave asynchronously. If you are sending data to the remote host faster than it can process it, or faster than the network's bandwidth allows, the outgoing queue might fill up. When this happens, the operation The BytesSent property shows how many bytes were sent (if any). If 0 bytes were sent, then you can wait for the ReadyToSend event before attempting to send data again. (However, please note that ReadyToSend is not fired when part of the data is successfully sent).
Shutdown Method (IPDaemon Module)

StartSSL Method (IPDaemon Module)
Starts SSL negotiation on a connection.
Syntax
Remarks
This method is used to start SSL negotiation on a plaintext connection. Please refer to the SSLStartMode property for more information.
Note that the Connected event will fire again after SSL negotiation is complete.
StopListening Method (IPDaemon Module)
Stops listening for new connections.
Syntax
public func stopListening() throws -> Void
- (void)stopListening;
Remarks
This method stops listening for new connections. After being called any new connection attempts will be rejected. Calling this method does not disconnect existing connections.
To stop listening and disconnect all existing clients call Shutdown instead.
Connected Event (IPDaemon Module)
Fired immediately after a connection completes (or fails).
Syntax
- (void)onConnected:(int)connectionId :(int)statusCode :(NSString*)description;
Remarks
If the connection is made normally, StatusCode is 0, and Description is "OK".
If the connection fails, StatusCode has the error code returned by the system. Description contains a description of this code. The value of StatusCode is equal to the value of the system error.
Please refer to the Error Codes section for more information.
ConnectionRequest Event (IPDaemon Module)
Fired when a request for connection comes from a remote host.
Syntax
func onConnectionRequest(address: String, port: Int32, accept: inout Bool)
- (void)onConnectionRequest:(NSString*)address :(int)port :(int*)accept;
Remarks
This event indicates an incoming connection. The connection is accepted by default. Address and Port will contain information about remote host requesting the inbound connection. If you want to refuse it, you can set the Accept parameter to False.
DataIn Event (IPDaemon Module)
Fired when data comes in.
Syntax
- (void)onDataIn:(int)connectionId :(NSData*)text :(BOOL)EOL;
Remarks
Trapping the DataIn event is your only chance to get the data coming from the other end of the connection specified by ConnectionId. The incoming data is provided through the Text parameter.
EOL indicates whether the EOL string was found at the end of Text or not. If the EOL string was found, then EOL is True.
If Text is part of data portion of length larger than either DefaultMaxLineLength or with no EOL strings in it, then EOL is False. Please note that this means that one or more DataIn events with EOL set to False can be received during a connection.
If the EOL property is "" (empty string), then EOL can be disregarded (it is always True).
Note that events are not re-entrant. Performing time consuming operations within this event will prevent it from firing again in a timely manner and may impact overall performance.
Disconnected Event (IPDaemon Module)
Fired when a connection is closed.
Syntax
- (void)onDisconnected:(int)connectionId :(int)statusCode :(NSString*)description;
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 system. Description contains a description of this code. The value of StatusCode is equal to the value of the system error.
Please refer to the Error Codes section for more information.
Error Event (IPDaemon Module)
Information about errors during data delivery.
Syntax
- (void)onError:(int)connectionId :(int)errorCode :(NSString*)description;
Remarks

ErrorCode contains an error code and Description contains a textual description of the error. For a list of valid error codes and their descriptions, please refer to the Error Codes section.
ConnectionId indicates for which connection the error is applicable.
ReadyToSend Event (IPDaemon Module)
Fired when the component is ready to send data.
Syntax
func onReadyToSend(connectionId: Int32)
- (void)onReadyToSend:(int)connectionId;
Remarks
The ReadyToSend event indicates that the underlying TCP/IP subsystem is ready to accept data after a failed DataToSend. The event is also fired immediately after a connection is established.
SSLClientAuthentication Event (IPDaemon Module)
Fired when the client presents its credentials to the server.
Syntax
func onSSLClientAuthentication(connectionId: Int32, certEncoded: Data, certSubject: String, certIssuer: String, status: String, accept: inout Bool)
- (void)onSSLClientAuthentication:(int)connectionId :(NSData*)certEncoded :(NSString*)certSubject :(NSString*)certIssuer :(NSString*)status :(int*)accept;
Remarks
This is where the server can decide whether to continue 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").
SSLConnectionRequest Event (IPDaemon Module)
Fires when an SSL connection is requested.
Syntax
func onSSLConnectionRequest(connectionId: Int32, supportedCipherSuites: String, supportedSignatureAlgs: String, certStoreType: inout Int32, certStore: inout String, certPassword: inout String, certSubject: inout String)
- (void)onSSLConnectionRequest:(int)connectionId :(NSString*)supportedCipherSuites :(NSString*)supportedSignatureAlgs :(int*)certStoreType :(NSString**)certStore :(NSString**)certPassword :(NSString**)certSubject;
Remarks
This event fires when an SSL connection is requested and provides an opportunity to select an alternative certificate to the connecting client.
Note: This setting is only applicable when UseInternalSecurityAPI is set to True.
This event allows the class to be configured to use both RSA and ECDSA certificates depending on the connecting client's capabilities.
ConnectionId is the connection Id of the client requesting the connection.
SupportedCipherSuites is a comma separated list of cipher suites that the client supports.
SupportedSignatureAlgs is a comma separated list of certificate signature algorithms that the client supports.
CertStoreType is the store type of the alternate certificate to use for this connection. 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. |

Remarks
The event is fired for informational and logging purposes only. Used to track the progress of the connection.
Connection Type
This is a currently connected client.
Remarks
This type describes the connection of a client that is currently connected to the class. You may use the different fields of this type to manage the connection.
Fields
acceptData Bool |
Setting this property to False, temporarily disables data reception (and the DataIn event) on the connection. Setting this to True, re-enables data reception. Note: It is recommended to use the PauseData or ProcessData method instead of setting this property. |
bytesSent Int32 |
This property shows how many bytes were sent after the last assignment to . Please check for more information. Note: This property will always return 0 when the class is operating in the synchronous mode (i.e., the Timeout property is set to a positive value). |
connected Bool |
This property is used to disconnect individual connections or to show their status. The property may be set to to close the connection. also shows the status of a particular connection (connected/disconnected). How and when the connection is closed is controlled by the Linger property. Please refer to its description for more information. Note: It is recommended to use the Connect or Disconnect method instead of setting this property. |
connectionId String |
This property contains an identifier generated by the class to identify each connection. This identifier is unique to this connection. |
dataToSendB Data |
This property contains a string of data to be sent to the remote host. It is a write-only property. Assigning a string to the makes the class send the string to the remote host. The Send method provides similar functionality. When is set to 0, the class will behave asynchronously. If you are sending data to the remote host faster than it can process it, or faster than the network's bandwidth allows, the outgoing queue might fill up. When this happens, the operation The BytesSent property shows how many bytes were sent (if any). If 0 bytes were sent, then you can wait for the ReadyToSend event before attempting to send data again. (However, please note that ReadyToSend is not fired when part of the data is successfully sent). Note: It is recommended to use the Send or SendBytes method instead of setting this property. |
dataToSend String |
This property contains a string of data to be sent to the remote host. It is a write-only property. Assigning a string to the makes the class send the string to the remote host. The Send method provides similar functionality. When is set to 0, the class will behave asynchronously. If you are sending data to the remote host faster than it can process it, or faster than the network's bandwidth allows, the outgoing queue might fill up. When this happens, the operation The BytesSent property shows how many bytes were sent (if any). If 0 bytes were sent, then you can wait for the ReadyToSend event before attempting to send data again. (However, please note that ReadyToSend is not fired when part of the data is successfully sent). Note: It is recommended to use the Send or SendBytes method instead of setting this property. |
eolB Data |
The EOL property is used to define boundaries in the input stream using the value of the property. The EOL property is especially useful with ASCII files. By setting it to , the incoming ASCII text stream can be split into lines. In this case, one event is fired for each line received (as well as in packet boundaries). The . bytes are discarded. The EOL property is a binary string. This means that it can be more than one byte long, and it can contain NULL bytes. |
eol String |
The EOL property is used to define boundaries in the input stream using the value of the property. The EOL property is especially useful with ASCII files. By setting it to , the incoming ASCII text stream can be split into lines. In this case, one event is fired for each line received (as well as in packet boundaries). The . bytes are discarded. The EOL property is a binary string. This means that it can be more than one byte long, and it can contain NULL bytes. |
idleTimeout Int32 |
This property contains the idle timeout for this connection. This property is similar to DefaultIdleTimeout but may be set on a per-connection basis to override DefaultIdleTimeout. This property specifies the idle timeout (in seconds) for the connected client. When set to a positive value, the class will disconnect idle clients after the specified timeout. This applies only to clients that have not sent to received data within the specified number of seconds. If set to 0 (default), no idle timeout is applied. Note: DoEvents must be called for the class to check existing connections. |
localAddress String |
This property shows the IP address of the interface through which the connection is passing. is important for multihomed hosts so that it can be used to find the particular network interface through which an individual connection is going. |
maxLineLength Int32 |
This property is the size of an internal buffer that holds received data while waiting for an string. If an string is found in the input stream before bytes are received, the DataIn event is fired with the EOL parameter set to True, and the buffer is reset. If no EOL is found, and bytes are accumulated in the buffer, the DataIn event is fired with the EOL parameter set to False, and the buffer is reset. The minimum value for is 256 bytes. The default value is 2048 bytes. |
readyToSend Bool |
This indicates whether the class is ready to send data. This property indicates that the underlying TCP/IP subsystem is ready to accept data. This is True after a client connects but will become False after a failed . After a failed , the ReadyToSend event will fire and this property will be True when data can be sent again. |
recordLength Int32 |
If set to a positive value, this setting defines the length of the data records to be received. The class will accumulate data until RecordLength is reached and only then will fire the DataIn event with the data of length RecordLength. This allows data to be received as records of known length. This value can be changed at any time, including within the DataIn event. A value of 0 (default) means this setting is not used. Note: It is recommended to use the ChangeRecordLength method instead of setting this property. |
remoteHost String |
This property shows the IP address of the remote host through which the connection is coming. The connection must be valid or an error will be fired. If the class is configured to use a SOCKS firewall, the value assigned to this property may be preceded with an "*". If this is the case, the host name is passed to the firewall unresolved and the firewall performs the DNS resolution. |
remotePort Int32 |
This property shows the Transmission Control Protocol (TCP) port on the remote host through which the connection is coming. The connection must be valid or an error will be fired. |
singleLineMode Bool |
This property shows the special mode for line-oriented protocols. When SingleLineMode is True, the class treats the incoming data stream as lines separated by carriage return (CR), line feed (LF), or CRLF. The EOL property is ignored. |
timeout Int32 |
This property specifies a timeout for the class. If the property is set to 0, all operations return immediately, potentially failing with a WOULDBLOCK error if data cannot be sent immediately. If is set to a positive value, data is sent in a blocking manner and the class will wait for the operation to complete before returning control. The class will handle any potential WOULDBLOCK errors internally and automatically retry the operation for a maximum of seconds. The class will use DoEvents 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 . Please note that by default, all timeouts are inactivity timeouts, i.e. the timeout period is extended by Timeout seconds when any amount of data is successfully sent or received. The default value for the property is 0 (asynchronous operation). |
userDataB Data |
The property holds connection-specific user-specified data. User-specified data may be set or retrieved at any point while the connection is valid. This provides a simple way to associate arbitrary data with a specific connection. |
userData String |
The property holds connection-specific user-specified data. User-specified data may be set or retrieved at any point while the connection is valid. This provides a simple way to associate arbitrary data with a specific connection. |

Configuration Settings (IPDaemon Module)
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.IPDaemon Configuration Settings | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
AllowedClients:
A comma-separated list of host names or IP addresses that can access the class.This setting defines a comma-separated list of host names or IPv4 addresses that may access the class.
The wildcard character "*" is supported. The default value is "*" and all connections are accepted.
When a client connects, the client's address is checked against the list defined here. If there is no match, the ConnectionRequest event fires with an Accept value set to False. If no action is taken within the ConnectionRequest event, the client will be disconnected. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
BindExclusively: Whether or not the component considers a local port reserved for exclusive use. If this is true (default), the component will bind to the local port with the ExclusiveAddressUse option set, meaning that nothing else can bind to the same port. Also the component will not be able to bind to local ports that are already in use by some other instance and attempts to do so will result in failure. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
DefaultConnectionTimeout:
The inactivity timeout applied to the SSL handshake.This setting specifies the inactivity (in seconds) to apply to incoming SSL connections. When set to a positive value
if the other end is unresponsive for the specified number of seconds the connection will timeout. This is not applicable
to the entire handshake, only the inactivity of the connecting client during the handshake if a response is expected
and none is received within the timeout window. The default value is 0 and no connection specific timeout is applied.
Note: This is only applicable to incoming SSL connections. This should only be set if there is a specific reason to do so. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
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. InBufferSize is shared among incoming connections. When the property is set, the corresponding value is set for incoming connections as they are accepted. Existing connections are not modified. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
KeepAliveInterval:
The retry interval, in milliseconds, to be used when a TCP keep-alive packet is sent and no response is received.A TCP keep-alive packet will be sent after a period of inactivity as
defined by KeepAliveTime. If no acknowledgement is received from the remote host the keep-alive packet
will be re-sent. This 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.

KeepAliveTime: The inactivity time in milliseconds before a TCP keep-alive packet is sent.By default the operating system will determine the time a connection is idle before a 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. This setting is applicable to all connections. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
MaxConnections:
The maximum number of connections available.
The maximum number of connections available. This property must be set before Listening is set
to True, and once set, it can no longer be changed for the current instance of the class.
The maximum value for this setting is 100,000 connections.
Use this setting with caution. Extremely large values may impact performance.
The default value is 1000.
Note: Unix/Linux operating systems limit the number of simultaneous connections to 1024. |

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. OutBufferSize is shared among incoming connections. When the property is set, the corresponding value is set for incoming connections as they are accepted. Existing connections are not modified. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
TcpNoDelay:
Whether or not to delay when sending packets.
When true, the socket will send all data that is ready to send at once. When
false, the socket will send smaller buffered packets of data at small intervals.
This is known as the Nagle algorithm.
By default, this config is set to false. |

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 etc). OpenSSL recommends to use the c_rehash utility to create the necessary links. Please refer to the OpenSSL man page SSL_CTX_load_verify_locations(3) for details. |

Whether to check the Certificate Revocation List for the server certificate.This setting specifies whether the class will check the Certificate Revocation List specified by the server certificate. If set to 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 .
When set to (default) the CRL check will not be performed by the class. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
SSLCipherStrength:
The minimum cipher strength used for bulk encryption.
This minimum cipher strength 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.
Please note that this setting contains the minimum cipher strength requested from the security library. The actual cipher strength used for the connection is shown by the SSLStatus event. Use this 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 config setting. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
SSLEnabledCipherSuites:
The cipher suite to be used in an SSL negotiation.The enabled 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 UseInternalSecurityAPI is False (default):
obj.config("SSLEnabledCipherSuites=*");
