We are building that scale of environment. For better or worse, we have been so overrun with consulting work that we are way behind where we hoped to be in our X2Go build but we have taken a different approach.
We integrated X2Go and Linux-VServer. Each user has a dedicated system (great for things like non-repudiation) but the extra resource requirements are minimal.
Even with RAM? I think every user needs his own OpenOffice in RAM, so you need much more RAM this way. But maybe I'm wrong.
We have been thinking about using Linux containers. But we decide first to work with some shared virtual machines because we have more experience with that. http://lxc.sourceforge.net/
We then moved the x2gocleansession processing to the VServer host so there is only one daemon running every five seconds instead of hundreds.
We also adapted the database to use schemas - one per user, and triggers for coordinating individual user changes with the master database used by x2gocleansession and other reporting utilities we created. Thus, we have a single database for all those potentially hundreds of X2Go servers.
Finally, we adapted the x2go printing so that we could use a single CUPS server for all X2Go users and not have hundreds of instances of CUPS running.
So far it has scaled very nicely but I am way behind in seeing how we would make the same changes to 3.99 - John
Does every user have it's own IP on the server?
With regards, Paul.
