Thanks Ralph.
I've done most of that so far. I've got a 3c905 NIC card on one,
and a pcnet based card on the other.
I've got pinging working between the two now. :) The little
network lights flash. Woohoo!
I have both of my boxes shut down pretty tight, so I can't telnet.
How does one allow telnetting, but only from a certain domain? Do I
add the line:
ALL : mydomain.com
in hosts.allow? And if so, do I just need to uncomment out the
telnet line in inetd.conf?
Thanks,
Rob.
