Hmm. Weird. I dimly remember that tcpwrappers did something
similar: to check the host name they sometimes tried a
reverse host lookup, which took its time when it failed.
But perhaps I'm up the wrong alley.
Possibly watching the connection attempt with tcpdump or
wireshark sheds light on this.
The behavour of ssh you describe is weird indeed -- the
MOTD must be coming from the server side, so the connection
is established already. As if the shell were checking something
before it decides to talk to you.
Hmmm. Sorry to be so unspecific.
