Imagine a situation where another Administrator user has connected to your router, and has started some monitoring action, bandwidth test, scan or any other feature that runs indefinitely, and then gone home.

You can terminate other running commands from your console within the “/system script job” menu.

To print running commands:

[admin@Router1-Home] /system script job> pr

# SCRIPT                       OWNER                      STARTED

0                              admin                      jan/12/2010 02:38:46

1                              admin                      jan/12/2010 02:38:53

[admin@Router1-Home] /system script job>

To kill a running command:

[admin@Router1-Home] /system script job> remove numbers=0
