Unable to connect to a port using telnet

[schamarthy]

Hi

i have installed our application on a suse linux box. i am actually tryin to connect to the suse linux box on the port specified by that application.

i am unable to connect to the application with that port.

things i have done

i made sure that the application is running

i am able to connect to that port from the localhost(suse) from that suse box

to verify i have installed tomcat and i am able to connect to tomcat port from my windows box

can anybody help me what might have gone wrong with that particular port

i am testing with telnet <ip> <port> to check if that port is open

Have you opened the port on your router?

hi ...i have checked the port its open it was working till yesterday

Ok, so what has been changed since yesterday?
And dont say "nothing"

Other than that, you could check on the server with tcpdump, if and what connects there.
(assuming, eth0 is the network card with the right IP, please insert the correct port)

tcpdump -i eth0 -n port <PORT>

Also try to do a ping and tracert from your windows box to the server and check if it is even reachable.
