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 ;)

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".

    • "The company has recently announced the forming of a new agentic AI team to develop an agentic AI framework for use in robotics." I wonder if any of their executives attented, "Microsoft Build 2025" last month?
    • Microsoft Build conference to leave Seattle after years in the city by Pradeep Viswanathan Microsoft Build is a flagship annual developer conference held by Microsoft since 2011. In 2017, Microsoft relocated Build from San Francisco to its home turf in Seattle. The proximity to its main campus allowed greater participation from its own engineers and executives, offering attendees a more integrated experience. Today, Jonathan Choe revealed on X that Microsoft has decided to move its Build developer conference out of Seattle. He discovered this information via an email sent by Visit Seattle to its members. Visit Seattle is a private, non-profit destination marketing organization that promotes travel to Seattle and King County. As a result of the move, Seattle-based hotels could lose approximately 9,314 room nights annually. Surprisingly, Visit Seattle’s message included several details about Microsoft’s reasons for the change. The primary reason appears to have come from within Microsoft itself. The company feels that Build lost momentum post-COVID, and the scheduling conflict with Google I/O, a competing event, has made it harder to attract the intended audience. Microsoft’s leadership believes they can better re-energize the program and boost attendance by moving it out of Seattle. The note even suggests that Build will likely be relocated to San Francisco or Las Vegas in 2026. Another factor contributing to the decision is the condition of the city. Last month, during the conference, Microsoft leadership and attendees walked between the Hyatt Regency and the Arch building on 8th Street. Reportedly, there were complaints about the general uncleanliness of the area, the visible presence of individuals using drugs, and unhoused individuals in a recurring tent in the Arch Tunnel. Visit Seattle believes these concerns also played a role in Microsoft’s final decision to relocate Build. Given Microsoft's high-profile presence and the economic impact of the event, this relocation may spark a political storm within the Seattle mayor’s office, drawing criticism over the city’s handling of downtown conditions.
    • This is very exciting, happy to see it come back to RC.
    • What did you have to do for that? Are the steps similar to W10?
