LocalPort Property

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

Syntax

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

Default Value

3305

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

This property must be set before OFTPServer 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 this property after OFTPServer 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 OFTPServer 'listening' on a particular port at one time).

The default value for plaintext communication is 3305. If UseSSL is set to true, set this value to 6619 (the default port for SSL communication).

Data Type

Integer
