The most likely cause is a problem with the reverse DNS for the IP
address you're coming from (either your IP address doesn't have a
reverse DNS entry, or the web server is unable to look it up). Try
this once you're logged in on the web server:
/bin/sh -c 'host ${SSH_CLIENT%% *}'
(mind the space before the star!)
If your reverse DNS is working, this should print out a single line
almost immediately; if it hangs for more than a few seconds, you have
a DNS problem.
