Linux: how to logout if there is no user access?

Question

Debian

I just noticed that users returned 11 identical users. Presumably these are sessions that ended unexpectedly for me (SSH idle for a while), how do I end all these sessions? root access is.

Answer 1

Output who is currently logged in according to FILE. If FILE is not
specified, use /var/run/utmp . /var/log/wtmp as FILE is common.

If there are no suspicious processes - just score, it happens. If there is, kill the processes, but sometimes that doesn't help either. Of course, you can clean these files with pens, but they are in a "non-human format".

Answer 2

you can find processes and bang them:
ps aux | grep <process name> - find out the PID
kill -9 PID
