How to know what user belongs to what ip on debian

Is there a way to see a list of all current logged in user on a Debian server? Sometimes it is very useful to do so, e.g. before updating certain plugins etc.

Any software or built-in features? All users will log in through ssh.

debian ssh user-management

    use the who command. It will show you the username and the terminal/pseudo terminal that they are using, as well as what time they logged in:

        migs     pts/0        2012-02-15 17:46 (:0)
    migs     pts/1        2012-02-15 17:46 (:0)
    migs     pts/2        2012-02-15 17:48 (:0)

    Mine shows three instances of me because I've got two terminal windows open, plus my log-in to the box.

    You could also use the last command. This will show the most recently logged in people, as well as currently logged in users.

        migs     pts/2        :0               Wed Feb 15 17:48   still logged in   
    migs     pts/1        :0               Wed Feb 15 17:46   still logged in   
    migs     pts/0        :0               Wed Feb 15 17:46   still logged in

  2. The who command will do the job and show all users logged in.
