How to kill a users SSH Connection


Recommended Posts

Hi,

Yes I have been using kill however listing the processes for sshd will list ALL processes of sshd, sometimes I want to kill just 1 user and killing sshd will kill everyone which I dont want. If I want to kill every I just restart sshd with 'service sshd restart'

The only way using kill to kill sshd would be handy is if I could find out which user was using which instance of sshd so I could kill just that 1 instance of sshd. is there any way to find out what user is using what PID for sshd?

using 'w' will only display the programs a user is currently running so that doesnt work.

Anyone got any other ideas?

can't you just ps -u username (do you know their username?) this will give you the pid of their connection

[bud@<hidden> bud]$ ps -u bud

PID TTY TIME CMD

20444 ? 00:00:00 sshd

20445 pts/0 00:00:00 bash

20478 pts/0 00:00:00 ps

[bud@<hidden> bud]$

And then kill that PID ;)

Never thought of that until now :laugh:

BudMan you are TheMan!

Cheers so much, it works a treat :thumbsup:

Whey you kill -1, you are killing and restarting a process on your server (In this case the SSH Daemon (sshd) or ssh session process). Since the SSH session is actually a connection initiated by the SSH client, you have really no way of affecting what happens on that end, and that includes an auto restart of the session. As far as the client is concerned, when your process stops, it losses the connection and the remote user will see something like "Remote Server termintated connection" OR "Remote Connection lost".

    • Staged. It's a requirement that vehicles are strapped down to the bed. Usually wheel and/or chassis tie downs are used. That appears to just be on the winch.
    • I feel Apple's big problem is the lack of big data to train any AI LLM model. They have statistics on usage, but they don't have the written social media, messaging (they were early adopters of end-to-end encryption), they didn't scrape the Internet before the book companies and new sources were wise. So they have no choice but to use a third party LLM provider. Which ties them in knots with their own stance on security and privacy. In short, they are royally stuffed when it comes to developing an in-house AI.
    • Nothing is black and white. Democracy can suck, just as communism can. The risk is people who blindly think one is vastly superior over the other. Democracy needs a lot to make it work well, and there are many examples around the world of it. Good education, mandatory voting, accessible voting, and removing money from politics are just a few elements that need to be sorted for a functional democracy. The USA is the playbook on what not to do with democracy.
