Check Users Logged In To a Router

Purpose

You may need to take note of the users currently logged in to a router.

Action

To list all users who are currently logged in to a router, enter the following JUNOS command-line interface (CLI) operational mode command:


            
                                     user@host> show
                     system users

Sample Output

user@host> show system users

1:49PM PDT up 6:44, 3 users, load averages: 0.00, 0.00, 0.00
USER     TTY      FROM                              LOGIN@  IDLE WHAT

blue     p2       level5.company.net               2:30PM      - -cli

Meaning

The sample output lists information about the users who are currently logged in to a router. There are three users, one of whom has not recently accessed the router. Two of the users are running the CLI, and one is working from the UNIX-level shell (csh). Table 43 lists and describes the fields in the output of the show system users command.
