3Com Router 3000 Ethernet Family
Configuration Guide
I. Starting the terminal service
Table 6-8 Enable the terminal service
Enable the shell service
Disable the shell service
Caution:
By default, the terminal service is enabled on all user interfaces.
For example:
[3Com] user-interface vty 0 4
[3Com-ui-vty0-4] undo shell
After you configure the undo shell command, no connection can be set up. This,
however, does not affect those users that have telnetted onto the router.
II. Setting idle-timeout disconnection of a terminal user
Table 6-9 Set the idle-timeout disconnection function for terminal users
Set the
function for the users.
Restore
disconnection setting for the users.
By default, the idle-timeout disconnection function is enabled and the timeout time is
set to 10 minutes. In other words, if there is no operation in 10 minutes, the TTY will
automatically disconnect. Configuring idle-timeout 0 will disable the idle-timeout
disconnection function.
III. Configuring user interface locking function
This configuration is used to lock the current terminal line and remind you to enter the
password, in case any other person operates on the terminal line without your
presence.
