ouch. ok.. I thought I briefly covered most of what you are asking me.
I have two computers, A & B.
A & B are networked through a hub.
A & B are on the same subnet ( 192.168.1.* )
A is Windows 98 and runs SBBS (SBBS box)
B is SCO OpenServer 5.0.4
I have both A & B entered in the hosts file on both A & B
I can telnet from A to B, both by IP and by hostname
I can telnet from B to A, both by IP and by hostname
I can telnet from A to the world, since any external IP or hostname goes
through my router. The same goes for Computer B.
Did I mention I do Network administration as my real job?
I use a firewall for my *incoming* traffic, and port 23 (telnet) is fixed to
forward to my SBBS box ( A ).
When logged in to Synchronet, and choosing the external doors, and picking the
'other BBS systems', Synchronet successfully telnets out to the ones that are
up.
When I duplicate one of the entries that is working, and put my the IP or
hostname of my Computer B in, save, shutdown SBBS and restart SBBS, log in and
try to connect... it goes through the motions but does not connect. When
monitoring port 23 from Computer B, nobody ever knocks.. yet I can open a
telnet window and connect immediately without problems....
Sooo... what is Sychronet doing differently than my telnet program?
I guess I could try adding the route command, but should not have to since we
are on the same class c network. I'll drop to ;dos and see if it helps....
