n is a valid TCP/IP port number. The default is value 23.
Port is the TCP/IP port number for Telnet connections. If multiple InterSystems IRIS® data platform configurations are to run on the same host at the same time, a different Telnet port number must be specified for each configuration. Clients can attach to configurations using the non-default port number by specifying the port number when they invoke Telnet on the client system. Telnet, with or without SSL, can be configured on any port; it does not require the use of port 992.
InterSystems IRIS Telnet settings apply only to Windows configurations in which InterSystems supplies the Telnet servers. This parameter is ignored for UNIX® systems.
Changing This Parameter
On the Telnet Settings page of the Management Portal (System Administration > Configuration > Device Settings > Telnet Settings), in the Telnet Port Number field, enter a TCP/IP port number.
Instead of using the Management Portal, you can change Port in the Config.Telnet class (as described in the class reference) or by editing the CPF in a text editor (as described in the Editing the Active CPF section of the “Introduction to the Configuration Parameter File” chapter in this book).
