Telnet port number.


[Telnet]    Port=n


The value n is the TCP/IP port number for Telnet connections. If multiple Caché configurations are to run on the same host, 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.

Caché Telnet settings apply only to Windows configurations in which InterSystems supplies the Telnet servers. This parameter is ignored for UNIX® systems.



Range of Values

Valid TCP/IP port number. The default is 23.

Management Portal
