I'm having a bit of trouble. My SSH connection hangs for about 10 seconds when logging in. I've tried disabling the system info MOTD and a number of other things but it just doesn't seem to work. Trying ssh user@host -vvv
doesn't help either as the log ends before the hang. It just says:
Last login: Wed Apr 17 12:52:04 2013 from 194.xx.xx.xx
Then hangs for a few seconds until it displays the prompt (user@host $
) One interesting thing to note: If I press ctrl+c
during this hang, it immediately solves it and the prompt flashes up so I'm guessing it's a process that is hanging. What's the best way to fix this?

This is usually because one of the files used by login has some function that takes a long time to return. It will commonly be either in your own home directory, where you should look at
If it's none of those, look in /etc for the same files, but usually without the dot:
and so on. The culprit will often be something that does a DNS lookup, but it might also be that you have it set to check when you last logged on, and your
utmp
/wtmp
/btmp
is very large.
