[comp.unix.xenix.sco] Strange TCP/IP problem, Please help.

Help,

This is pretty lenghtly so please bare with me.

I had a 2 node tcp/ip lan running on thin wire using 3Com 3c053
cards running between 1 386/20 running SCO XENIX and 1 486/25 running
SCO UNIX 3.2 in both cases I am using SCO TCP/IP.  Lets call there nodes
A and B.

         A <---------> B
address
--------
A = 132.147.160.5
B = 132.147.160.10

All communication between A and B works great (ftp,telnet,rcmd,rlogin).

Then I added node C another 386/25 running SCO XENIX with same 3Com and
same TCP/IP.  Like so.

	A <---------> B <--------> C

addresses
---------
A = 132.147.160.5
B = 132.147.160.10
C = 132.147.160.7

Now here comes the part that stumps me. Systems A and B still work fine
as described above but System C cannot telnet,ftp to machine B.  It
just says trying.... and the eventually times out.  But System C can
telnet,ftp,ping.... to System A. Also System A and B can telnet,ftp,
ping to C.

Does anyone have any ideas.  I could really use some.  

Please e-mail all responses.

Thanks,
Bryan
