At work I've been asked to set up vnc for a remote user (a vendor sysadmin to install 3d party software we've purchased). Of course I'm a bit skittish about allowing root access to this. Is there a way to configure vnc so that root cannot log in through it...? Or do I have to use some other utility to deny root access (e.g., securetty).

Maybe check the wiki: http://wiki.centos.org/HowTos/VNC-Server I would guess you just don't give root's vnc password?

That's a better doc than the one I was looking at... got it working now. Thanks much.

You can set the machine up to use VNC for the console.

Then, give the person a normal login which they will use to login to the machine from the console interface. Basically, it will be just like they are sitting at the machine a logging in with a user account.

I would also require the VNC to be tunneled through SSH for encryption since VNC does not do that internally.

Neil,

Thanks for the reply. Is it possible to make the ssh connection connecting to a linux box from a windows machine. The only ssh clients we have now for windows are winscp and putty. Realvnc (the Windows vnc client we have) has an encryption option (a box you can click), but it's grayed out (not clickable).

Is there some other windows client which has the ssh capability?

Thanks again.

I use cygwin ssh to connect CentOS servers from my windows laptop.

Or you could do it with putty. But, if you need more than occasional remote GUI access you should probably look at freenx/NX. It is much more responsive than vnc and runs over ssh by default.
