Hi,

I have typical problem.

I have 2 linux boxes both connected to a switch. One having IP address starting with 203.X.X.X and the other 202.X.X.X. I can telnet form the box with IP 202.X.X.X to 203.X.X.X but can't telnet from 203.X.X.X to 202.X.X.X.

Same is the case when I try to ping.

Can anyone help me out.

You have a digital switch? I'm impressed.

Can you ping from 203 to 202?

Probably not.

How does the switch know how to route things? Maybe it
has a virtual router or something?

I have recently started using "The Complete Linux OS 6.5" from McMillan Publishing, based on Linux-Mandrake 6.1 and was having much the same problem.
If you're using the same or similar Linux:

Read your error log at /var/log/secure.
if it says as mine did "cannot execute /usr/sbin/in.telnetd - no such file or directory"
(on the machine you can't telnet to)
mine did. I had not installed the telnet-server.
(rpm -i (path to it)/telnet-server(whatever the rest is) )
Good luck - mine works now.
