Iptable Rule

realvz · #1 26th February 2008, 06:39 PM

alright i am connected to a machines miles away through ssh and i need to vnc into my machine. I have already configured the firewall to allow ssh but forgot about opening 5900 port, so i cannot tunnel vnc through ssh now.
I need the rule to open port 5900 from anywhere, without loosing my firewall (the default one that comes for F8) the next time i use it.

Thanks.

iptables -A INPUT -m state --state NEW,ESTABLISHED,RELATED -p tcp --dport 5900 -j ACCEPT

You can also vnc over ssh as well. Google for vnc over ssh for help there. it would be a bit more secure this way. This way you only have one port open to maintain for vulneriblities.
