[solved] sshd not disconnecting clients on close

rezza · 2011-02-02 16:07:54

When I shut down my sshd, either restarting the machine or manually, currently connected clients are not disconnected. Their ssh sessions just hang, and the terminal has to be closed. How can I make "/etc/rc.d/sshd stop" actually boot clients off?

Their ssh sessions just hang, and the terminal has to be closed.

You don't have to close the terminal. The OpenSSH client (i.e. ssh) supports 'escape sequences', and you can force the disconnect between the client and the server by pressing '~' and then '.'. That said, you must have entered a newline just before, so the sequence if often '<enter>', '~', '.'.

If you want more info about this, look at the 'ESCAPE CHARACTERS' sections of the ssh man page.

Add to /etc/rc.d/sshd inside 'stop)' case:

for i in `/bin/netstat -lantp | /bin/grep -e ' \+[0-9]\+/sshd:' | sed 's|.* \+\([0-9]\+\)/sshd[:] .*|\1|g' | /usr/bin/sort -u`; do /bin/kill -s HUP $i; done

HUP sends a "hang up" signal to client. For best results use '/bin/kill' (vs 'kill' as it belongs to bash).
