Graphical management tool for multiple systems?
Does anyone know of a graphical tool or some tools for remotely managing a number of Linux systems? I've checked out Webmin and it's very nicely done, but it doesn't do quite what I want. You can apply some configuration functions to multiple systems, but only one at a time. There is not functionality to, for example, add a particular user to five different machines at once, or manage Apache config simultaneously across several machines.
We are using Red Hat Enterprise at our shop and our system administrators are hating it because they come from a Windows and Novell background and are not accustomed to doing everything on the command line. There are the Red Hat graphical administration tools of course but they are of very uneven quality. Some are OK, some are virtually unusable. Also, those tools all only work on the system they're installed on. They don't work on a whole bunch of machines at once.
Any advice would be appreciated. Thanks.
