DESCRIPTION

Service Port

For Telnet, SSH, FTP, HTTP or HTTPS services, you may change the default service

 

port by typing the new port number in the Server Port field. If you change the default

 

port number then you will have to let people (who wish to use the service) know the

 

new port number for that service.

 

 

Timeout

Type how many minutes a management session (via the web configurator) can be left

 

idle before the session times out. After it times out you have to log in with your

 

password again. Very long idle timeouts may have security risks.
