Norton: To follow on Andy's "If you can ssh...", what is your overall situation here? Is the remote box running a regular LinuxCNC (or EMC2 if earlier) over Ubuntu? If you can ssh into it and if your account permissions allow you to execute 'sudo' commands. then you can gain access to the entire desktop. Just enable the 'Remote Desktop' on the remote box and connect to it with a VNC client on your local box (such as "Applications/Internet/Remote Desktop Viewer" from the menu bar on a Ubuntu 10.04 box). Ubuntu's documentation of all this is pretty awful. Try resources such as http://ubuntuforums.org/archive/index.php/t-266981.html. OK, so the VNC protocol on which Remote Desktop is based can seem as slow as molasses in January (do people in the southern hemisphere use molasses?), which I expect the tcp/ip packet latency over the multiple gateways implicit in a 3000 mile journey exaggerates. Still, I've found it helpful where simple command-line access via ssh or single X-client access wasn't enough. One respondent in the URL noted above points out some alternatives to VNC. It's all a matter of how desperate you are:-) A quick Internet search took me to your CV based on which I could hazard an educated guess but I wonder if you are at liberty to tell us what this linear actuator is pushing back and forth? Regards, Kent PS - I know this final thought is elementary and I don't mean to be patronizing, but all this is easier to work out if you start with a 2-PC setup in your lab with one running a LinuxCNC simulator. Both the remote access and the LinuxCNC tricks being offered up can be freely exercised without danger of borking the remote host. ------------------------------------------------------------------------------ Learn Graph Databases - Download FREE O'Reilly Book "Graph Databases" is the definitive new guide to graph databases and their applications.
