x11vnc change port

[DexterLB]

the default port for x11vnc is 5901, but I want to change it to 5566. On the normal VNC this is done by editing /etc/xinetd.d/Xvnc, but how can I do it for x11vnc?

I'm not sure what script is starting x11vnc for you (please post here the file location when you learn it), but once you find it (perhaps grep -rl x11vnc /usr /etc) it would be something like:

x11vnc -rfbport 5566 ...

IT WORKS!!!! Thanks a lot

P. S. How can I mark the thread as solved?

IT WORKS!!!! Thanks a lot

What is the full path of the file you had to modify?

[DexterLB]

I made a shellscript with the following content:

#!/bin/sh
x11vnc -many -rfbauth ~/.vnc/passwd -rfbport 5566

and I use it to run x11vnc

Does that work with ports below 5900? I tried it with port 80 and it didn't work.

You have to be root/sudo to listen on ports less than 1024. Did you run it as an ordinary user?

[faustism]

No. I didn't. thank you. that worked. but i have to put "-5820" as the port when i try to connect to port 80.

You mean in the viewer, right? Some vncviewers (e.g. tightvnc, ssvnc) support the double colon notation:

vncviewer hostname::80

Hi i have a machine at the office that I SSH into with Putty & x11vnc. Using x11vnc through terminal like this;

ssh -t -L 5900:localhost:5900 "WANIPxx.xx.xx.xx" 'x11vnc -localhost -display :1'

I changed the SSH port from 22 to 3022 for security purposes and my SSH works fine but x11vnc fails, it just won't connect and I already corrected the appropriate ports on my firewall.

Do you know where I need to change the port for x11vnc to work like before the port change?

Thanks!
