I Could need some help here...

I'm running a java socket server on a 64bit Linux VPS and listening on a port 5555 however my clients aren't able to connect to that port.
When I run a netstat -anp on the server it gives me local address of ::ffff:127.0.0.1:5555and foreign address of :::* and the state is LISTEN.

Is the ::ffff:in the local address part causing the problem?

That address is your localhost interface, not an external interface. I assume your clients are connecting from "outside" the server, correct? If so, you'll need to set your java app to listen on whatever IP address is assigned to an outward-facing interface.

Oh! so if the IP address is for instance 192.168.0.55 I should setup java for 192.168.0.55:5555 rather than 127.0.0.1:5555 right? – Kevin Boyd Feb 5 '10 at 1:04
Yes, that should work. You should also verify that there are no iptables rules that may be blocking traffic to that IP/port. – EEAA Feb 5 '10 at 1:15
Well I am a noob on linux but I will check on how to do that! – Kevin Boyd Feb 5 '10 at 1:17
Well your suggestion worked for me! thanks a lot!! Luckily I didn't have to do up the iptables. – Kevin Boyd Feb 5 '10 at 1:24
