Hi there, i'm wondering if anyone can help me out here. I'm behind my university network firewall (who have blocked some ports) and i'm wondering how to get wrong certain ports, or find out which ports are open. I'm trying to have access to certain programs ( msn works thankfully) and i managed to get IRC to work by directing it to port 7000. basically i want to get DC++, which is another program to work externally (out of the university) but it won't connect me. Anyone have any clues or can shed some light here as to what i can do?

Please go to GFI.com & download lannet scanner & install in your client machine and scan your firewalled ip whether your needed port is allowed or not. and another way is just try with the passive IP in the configuration of DC++.

feel free to ask..

get a boot distro of Knoppix SDT and run it if you can change the boot order on the machines.

Don't be naughty with it though. There are lots of scanning tools on there.
