I had to hard reboot my server because I wasn't able to login through ssh and what was really strange is that
everything else (nat, dhcp, lighttpd, ntpd ..) was working. And now I see in the logs that the connections
were accepted, but I wasn't getting a shell and out of a few attempts I only once got a "Last login" message,
but nothing more. Neither was ssh server command_foo working. I can't find anything suspicious in the logs,
but maybe I am looking in the wrong place, any clues?
