VNC: disable physical mouse/keyboard

asymptote · 04-07-2008, 12:32 PM

Sometimes when I VNC into my box, people agitate me by moving the mouse or pressing keys on the keyboard. Is there a way to disable the physical mouse and keyboard will retaining control of the VNC mouse pointer and keyboard input? Thanks!

What OS is VNC server running under? What brand is it? Most of them have some settings for grabbing input.

I believe when you run vncviewer, if you go into options, there is a way to disable it. It's there when I remote in to other machines.

Regards,

I'm using VNC on Fedora 8. I've been through the Remote settings under System -> Preferences -> Internet and I don't see any options for disabling the physical mouse and keyboard

One thing I wondered about is the /dev directory. I've no experience with this directory, but I thought maybe it would have something to do with the peripherals. The keyboard is connected via PS/2, and mouse via USB. I know I can see the mouse using the lsusb command, but I'm not familiar with any command to disable it. Does the /dev directory have anything to do with it?

You do not want to disable anything by removing /dev/ entry.

Well, I think you should have some VNC server process.. Run

ps -auxwww | grep -i vnc

When I try and run your command I get the following:

Code:

[root@localhost ~]# ps -auxwww | grep -i vnc
Warning: bad syntax, perhaps a bogus '-'? See /usr/share/doc/procps-3.2.7/FAQ
root      5891  0.0  0.0   4044   744 pts/0    R+   21:50   0:00 grep -i vnc

I also tried 1, 2, and 3 w's but the same effect. Is that the correct command you wanted me to type? Thanks!

you could always rmmod the usb drivers form the kernel

Well, maybe no "-" before auxwww

Here's my output:

Code:

[root@localhost ~]# ps auxwww | grep vnc
root     11586  0.0  0.0   4016   460 pts/0    R+   22:40   0:00 grep vnc

I'm going to bed so I'll read the man page on this later as far as what its supposed to mean. Thanks!

Strange.. I cannot understand what is your VNC server..

asymptote · 04-16-2008, 07:06 PM

LoL why didn't you just ask? It's vino-server. I dunno why Fedora 8 uses that instead of just vnc-server but for some reason it does and for the most part it works

raskin · 04-17-2008, 01:57 PM

Well, I know that keyboard and mouse should be disabled in server settings. I know that it is only relevant when you have VNC server like x11vnc (or maybe vino-server..) that doesn't create a virtual screen, and uses physically attached X11 display instead. I know that it should be called grabbing input if not disabling input. But I have no idea of how is vino-server configured..

i do sharing with Tightvnc Viewer using x11vnc on fedora then both have mouse and keyboard control.is it possible if server side using mouse than automatically viewer should loose control.?
