Can't install software over VNC

Post by gstorm » 2012/05/24 03:50:01

I connected to a Centos 6.2 from a Windows machine via VNC.
It seems to not allow admin functions like install/update software. The authentication is ignored.
It works fine when I use a local terminal.

Am I missing something?

Welcome to the CentOS fora. Please see the recommended reading for new users linked in my signature.

I have seen similar problems with some brain-damaged X servers where consolehelper does not start to request the root password. A work-around is to [url=http://wiki.centos.org/TipsAndTricks/BecomingRoot]become root[/url] and run the required tools from the command-line. If memory serves the underlying problem has something to do with XDMCP.

For what it's worth, I experience this problem if I run vnc by itself. But, if I use nx which tunnels vnc through an ssh session, then I don't. I don't know what the difference is, but the latter is more secure anyway.
