So, you can telnet to the telnet port, but not to the HTTP port? Why are you using telnet to connect to the HTTP port anyway?

Hi,
i've got this strange n peculier problem,
i have a java server program running on, say mach1, which is listening on port 10991.
when i try to connect client to that server, it just cannot connect.

furthermore, i can telnet the server from client on port 23, but when i telnet the server on port 10991, it fails.

similarly, if the client and the server are runing on same machine and if i specify the destination addres in client as "localhost", it can connect, but when i specify the destn add as ip, it fails.

i havent seen anything like this before,
any help, any clue please

Sameer,

There are NO firewalls involved, or you just don't believe that your firewall should be involved with this connection?

If you're getting different results when you use 'localhost' vs. IP address, then the issue could be that the traffic is diverted outside the box, then back in again, making it subject to the rules of the firewall.

using 'localhost' will use the internal loopback address
using '127.0.0.1' should be the same as localhost
using an internal address such as '192.168.0.1' will confine the traffic to your local net.
using 'mymachine.mydomain.net' may resolve to an external address, which is subject to the firewall.

IF telnet can get through but 10991 cannot, that just seems to indicate further that the firewall is in play and that access has been allowed on some ports and not others.

A more precise description of your network topology would help in this discussion.
