I had already tried DNS settings. I edited nsswitch.conf and changed it to
files first, then dns, with this line:
hosts:      files dns [NOTFOUND=return] files

and made sure the IPs are in /etc/hosts, which they already were. One email
went out with alpine from another PC, but nothing more and it took just about
long enough to time out. Watching it in ps ax showed

startup with 172.20.20.100
then
cmd read: 172.20.20.100

but all the other ones show the startup line only, then when it times out on
the client, it changes from the IP to the entry in the hosts file. It's like
something is preventing things from moving. I'm wondering if I have a bad
cable or switch.

I am going to try sshd_config right now and see if that works. Remember, this
is the box that got duplicate libs which I had to manually delete. There are a
few duplicates again. It may not be related....

Okay, changing UseDNS no didn't help at all. Still taking a couple minutes to
connect via ssh.
