Systems Administration

Killing a Dangling SSH Session.

Background: I had previously SSH'd into a server and CD to directory /opt/foo when I got kicked out by network troubles. A colleague was trying to delete that directory and could not delete it.

• SSH into the server
• Execute who to get the active sessions.
• Try to locate the pts/N session from the list.
• Now execute ps -ef | grep -i sshd and from the list, locate the PID for the SSHD session that has pts/N.
