LocalPort Property

The TCP port in the local host where the component listens.

Syntax

 sshdaemon.getLocalPort([callback])
 sshdaemon.setLocalPort( localPort, [callback])

Default Value

22

Callback

The 'callback' parameter specifies a function which will be called when the operation completes (or an error is encountered). If the 'callback' parameter is not specified, then the method will block and will not return until the operation completes (or an error is encountered).

The callback for the getLocalPort([callback]) method is defined as:

function(err, data){ }

'err' is the error that occurred. If there was no error, then 'err' is 'null'.

'data' is the value returned by the method.

The callback for the setLocalPort([callback]) method is defined as:

function(err){ }

'err' is the error that occurred. If there was no error, then 'err' is 'null'.

'err' has 2 properties which hold detailed information:

err.code
err.message

Remarks

The LocalPort property must be set before IPDaemon starts 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 the LocalPort property after IPDaemon is in listening mode (after successfully assigning True to the Listening property).

The service port is not shared among servers (i.e. there can be only one IPDaemon 'listening' on a particular port at one time).

Data Type
