I remember some problems I had with sendmail, when I used dialup. It
would hang the bootup 60 seconds, while trying to resolve its own
hostname. It turned out that I needed to append a '.' to my hostnames in
the hostfile. Seeing that the names from tcpdump are asked for with a
dot at the end (indicating the final "top domain"?), it might be worth
trying to add a dot to your names?

I can understand that a 34 second delay while logging in is annoying :)
