Actually, I discovered that's not what's happening. I was wondering why
I was getting ping responses, but nothing else works. I did a telnet
jackie 25, and to my surprise I was connected to the mail server. It was
surprising because I didn't recall ever installing one on jackie. So I
did a telnet jennifer 25, and when I found myself connected to the same
mail server I knew something was wrong. I ran nmap against both hosts
and found that in both cases it was reporting my server's condition. I
now believe that since I don't have crossover cabling the ping responses
are false, and apparently each nic is `bouncing' all tcp/ip frames back
at the server's kernel, which responds back to the nic cards, which in
turn bounce the frames back at the terminal. I have no idea why it's
acting this way, but that's what's happening. I will simply have to get
a switch - no doubt about it now.

Done all that, but I'll have to redo it as soon as I get the switch and
reassign ip addresses again.

The switch should solve this too, shouldn't it? I hope so. With the
switch they'll be put back on the same subnet. I'll probably be back
with other problems after the switch is installed --- and hopefully
running right.
Thanks!
