How to change port number in vino ubuntu 11.10?
Cannot find option to change from port 5900 on vino vnc 'remote desktop' window, nor can I find it via gconf-editor as was available in previous ubuntu version.
sudo apt-get install dconf-tools
Press alt+f2 and type
remote access and change your port there, don't forget to tick the
use-alternative-port option so that vino uses the one you set:
Failing finding the configuration, you could set up iptables (the kernel-level firewall) to redirect another port to 5900 using something like this:
iptables -A PREROUTING -t nat -i eth0 -p tcp --dport 59000 -j REDIRECT --to-port 5900
Port 5900 would still be used for hosting it but so would port 59000.
I'm not sure if that it acceptable for your problem or not.
There is a brainstorm idea that was closed because it was thought of as a bug report: http://brainstorm.ubuntu.com/idea/25109/
Here is another question regarding this and the second answer mentions how to do it but I recommend using iptables: Enable remote VNC from the commandline?
UPDATE - As mentioned by the answer from Oli that would be the way to do it until the
vino-preferences readds the option again.
On Ubuntu 14.10, gconf-editor was required. dconf-editor set a value, but it was not used, and displayed as 0 (5900) in gconf-editor.
sudo apt-get install gconf-editor gconf-editor
