cannot telnet

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?

do you have trunking turned on on the port where your
203.x.x.x machine  is pluged in..?

another thing..  are you blocking anything from your box in your hosts.allow or hosts.deny files.?

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.
