Connection Timed out

I connect to a Sun Box through telnet but it timed out in couple of minutes.

Advance thanks for any idea...help...

This pretty much could be anything. Can you ping the Sun Box from your pc? If you can't ping you have a network problem. Could there be a firewall between your pc and the Sun Box? It could be blocking this. Can anyone else telnet into the Sun? Maybe it isn't even running telnet. A lot of site sare switching to ssh conectivity only.

Hi:-

Yes, I can login to system and if did not do anything on the system it timed out.
Its a firewall of our department and using Checkpoint. But the person who managed it, did not know how to solve this problem.

Thanks in advance.
