VNC Ports

[waliddz]

How do you open Ports 5800/5900 and 5500 in order to use UltraVNC?

[Nevil]

Use the following commands on your VPS:

Open port 5500:

iptables -A INPUT -p tcp --dport 5500 -j ACCEPT

Open port 5800:

iptables -A INPUT -p tcp --dport 5800 -j ACCEPT

Open port 5900:

iptables -A INPUT -p tcp --dport 5900 -j ACCEPT

After that save the rules with:

/etc/init.d/iptables save

Restart iptables to accept the new rule:

/etc/init.d/iptables restart

The port should be open, if not you maybe need to open them with the udp protocol instead of tcp. Change -p tcp to -p udp in the commands.

don't you need to open more ports for vnc?

Depends on your server and config. You can get away with just opening 1 port if you want.

By the way, I'd suggest using FreeNX instead.
It runs on your SSH port, so you don't have to open another port. Also, it's quite a bit faster (from my experiences).

its also secure, if you can about that.

Did you open up the port in your windows firewall or any other firewalls on your computer? Also are you sure you are using ports 5801/5900 and not 5901 or something?

I use Windows XP I desactivated Firewall
About Ports I don't know I not sure

[f8ll]

Try port 5901. You can check by running "netstat -an | grep vnc" on your sever
