Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

Hello everyone, I tried searching on google but not finding answers, I decided to post an interesting topic I hope for you too. Having logged in "es. 4 user" on my Debian, eg. from 4 different locations all with the logged user "debian" from one of these positions as I can do a logout of a single host connected? I try to explain better: - 4 hosts connected to the Debian server as a "debian". - From one of these hosts using "who-to" visualize all user related, but all are "debian", if I want to disconnect, and of course stop the operation that was running as that user I can do? using pkill-u debian-kill me disconnettte them all. thanks
to identify you can use the command last. You may need to use grep/awk to find out the the important lines probably, you need to investigate what is the way you like.

You can start by using 'last' as suggested by @pan64 in order to find the the tty and the location of users. For example:
Code:
└─› last | head | grep ^d
d pts/9 host/ip Sat Jun 2 20:13 still logged in
d ssh host/ip Sat Jun 2 20:13 still logged in
=> d pts/8 host/ip Sat Jun 2 20:13 still logged in <=
d ssh host/ip Sat Jun 2 20:13 - 20:13 (00:00)
d pts/7 host/ip Sat Jun 2 20:13 still logged in
d ssh host/ip Sat Jun 2 20:13 - 20:13 (00:00)
then you can get the processes executed by your user, by executing:
Code:
└─› ps -fu d
UID PID PPID C STIME TTY TIME CMD
d 17943 17917 0 Mar23 ? 00:00:00 sshd: d@pts/7
d 17946 17943 0 Mar23 pts/7 00:00:00 -bash
d 17987 17973 0 Mar23 ? 00:00:00 sshd: d@pts/8
d 17993 17987 0 Mar23 pts/8 00:00:00 -bash
d 18021 18001 0 Mar23 ? 00:00:00 sshd: d@pts/9
d 18022 18021 0 Mar23 pts/9 00:00:00 -bash
d 18858 17993 0 Mar23 pts/8 00:00:00 vim /home/d/example.txt
** in this example my user is 'd'.
so let's say I want to kill the session for the user 'd' logged in from 'host/ip', using the tty 'pts/8' which is running 'vim' for example. I would kill the '-bash' process which will kill user's session.
Code:
└─› kill -9 17993
or better yet you may want to send a SIGHUP (-HUP switch) to the PID instead of killing it with '-9' priority, because this will allow them to exit gracefully.
so you have a solution? Is this ok, or you have still some troubles? Why do you need another solution?
