How to change port number in vino?

Question

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.

Answer 1

Install dconf-editor

sudo apt-get install dconf-tools

Press alt+f2 and type dconf-editor

Navigate to desktop>gnome>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:

Answer 2

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.

Answer 3

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.

Answer 4

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
