Restrict keyboard short-cuts in x11vnc

How can I restrict keyboard shortcut options in x11vnc? for example, I want to res开发者_运维技巧trict Alt+F4, Alt+x, Ctrl+Q, etc.

Is -skip_keycodes option of any help here?

You can probably configure such shortcuts in your window manager. That way, such shortcuts won't be passed to the application, and you should be able to handle them.

But, since you seem to want an application running all the time (you want to prevent users from closing it), then it might be a good idea to write a simple script like this:

while true; do run_your_application ; done

That way, if the application crashes or is closed, it is restarted. (be careful about applications that fork themselves or detach from the terminal!)

On the other hand, if you just want a browser, you can try using the kiosk mode from Opera browser. See also kiosk software at Wikipedia.

Update: So you are using Gnome... I don't use Gnome, but a quick search at SuperUser gave me this answer:

https://superuser.com/questions/132666/how-to-disable-control-alt-arrow-gnome-window-manager-control-for-redhat-linux

[…] all the keyboard shortcuts gnome uses are under System, Preferences, Keyboard shortcuts.

But... Are you sure you want a Gnome environment running there? Do you really want users to be able to run and configure anything from your Gnome interface? Maybe you would prefer another more minimalistic Window Manager. Which one? I'm not sure, must look what are the alternatives and try some of them. Depending on the application, it might even be possible to run it with no window manager at all.

I don't what kind of problem you are trying to solve, but maybe using a VNC applet in a webpage in order to have access to one application might not be the best solution. Of course, it depends on what is the problem and who are the users.
