Affirmed for the general case. "30 second delay, then normal
network activity" _screams_ DNS misconfiguration, usually but not
always in the client side.

Forgive me if I am dense. According to the readout of "ssh -vvv gateway"
the connection is made immediately. Does that not indicate that it knew
where to go?
It's not the forward case that's the problem. The sshd daemon on the
server side attempts to find out where the connection is from by doing
a reverse-lookup. If the incoming IP hasn't got a DNS entry, the failing
DNS ip-lookup will time out in ~30s.
Cheers.

Thanks for responding. In all of my systems /etc/hosts is populated with
the name and LAN IP address of all other boxes. My gateway/firewall is a
5.4 Rel computer. I can ping that box "it's called gateway" with ping
gateway or ping 10.0.0.1 no problem.
I ssh there and it takes 40 seconds to provide me with a request for
passphase. Once I'm in there I can ping all other boxes with name or IP.
If I ssh from there to any box it takes 40 seconds for that next box to
request a password. This happens from any box to any box. It was working
perfectly until this week. It might be realted to me updating the
gateway box from 5.3 to 5.4 but I know I had accessed it right after
upgrade because it is headless and I had to ssh into it to do the
world/kernel thing.
Other than /etc/hosts and /etc/resolv.conf is there any other config
files I should check.
Thanks again for your time.
Robert
