dead ssh sessions
Sometimes, when I use ssh to log into my Linux box from Windows (puTTY program), it happens that Win crashes and then I lose my ssh connection.
Then I have to reconnect and log in again. But, when I check who is logged by who command, I see not only my current session, but also the old one (the one that I lost before due to Win crash)...
It looks like two users are on, but there is only one actually.
What to do now? How to remove the old session - or how to reuse it, if possible?
