Re: Progress bringing up tom4 and tom5



Tom,
 
You may want to consider (if you haven't already) looking into VNC (http://www.realvnc.com/). Running a local Viewer, you take control of a remote computer running a Server program.
 
I've used it to run equipment in a remote observatory from home over the internet. It works well. You can also connect computers each running different operating systems. The remote pc can still be operated at its location. I haven't controlled more than one pc at a time but I guess that could be done from within Linux.
 
Just a thought.

Mario
