From: Louis Maher Sent: Sunday, February 10, 2013 12:49 PM To: Orca List (orca-list@gnome.org) Subject: Orca Running on Remote Servers Folks, My company uses Red Hat 5.7 on Massively Parallel computers. A few of the nodes of the cluster of processors are login nodes. These login nodes are used for code editing and job submission. People in our company access the cluster through VNC (virtual network computing) which provides a graphical user interface (GUI) window running on Windows 7. I access the cluster using the character-based SecureCRT windows program which provides a SSH (secure shell) session into the cluster. Once in the cluster, I use the Linux screen program to get as many character- based windows as I want. The character-based approach is limited, and I do not have access to the GUI-based job setup and queuing systems. Often we write plug-ins to commercial software, and that commercial software brings its own powerful and inaccessible GUIs. Questions: If I had a laptop running Linux, is there a way to place Orca on the remote server and give me a GUI interface into the remote cluster? Technically I could make my Linux laptop part of the cluster, but would the job editing and job queuing programs need to be running on my laptop before I could access them? We have several domains, each with its own cluster. If I wanted to access these other domains, would I have to have a laptop specifically dedicated to each domain? Commercially available job-setup GUI's are extremely powerful for they provide a means to connect several smaller plug-ins to make complex flows. The output of the job scheduling GUI is an extremely complex XML file. I can make small changes in this file, but writing one of these files from scratch is not practical. So my base question is: If I had a laptop running Linux, is there a way to place Orca on the remote server and give me a GUI interface into remote computers? I will have to use Red Hat 5.7 for my effort.

I wonder if vnc would transfer braille. Under KVM there is a mechanism to forward braille to an instance of BRLTTY running on the host. On the guest system, if I remember rightly, a Baum braille display is emulated, then Qemu/KVM takes care of the communication with the instance of BRLTTY that runs on the host, and which drives the real braille device. I hope I have this roughly right. I haven't tried it in practice because I access guests via terminal sessions or ssh, but it should allow you to run Orca on a guest system. Brlapi has network support, I think, so you might be able to send the traffic to another machine. _______________________________________________ orca-list mailing list --
