I have a RHEL5 server with 4GB ram running SRSS 5.1. We have about 10
users across 15 DTUs. We "were" using uttsc to connect to a remote (states
away) Win2008R2 termserver that once logged in pushes a single app. We
found that when a user pulled their card to move to another DTU, the
portmapper in RHEL5 changed the printer ports from the original session
used to new ports. This caused printers not to redirect to the new session
correctly and caused all kind of print fun for the users! If they did
redirect, the "printer number" changed and the this confused the users.
So we moved to using RHEL5's rdesktop implementation. It does not seem to
have issues with the mapper and the session and printers stay statefull.
Printers work great. However, as DTU usage has increased with students in
full session, we are seeing lockups on the DTUs. The lockups seem to be
random. We can not pin it to any one operation done on the Win2008R2
server. Interestingly enough, if the user goes to a laptop and pulls the
rdesktop session to it, the session unfreezes and they can work. They
then pull it back to the DTUs and continue.
Are you running rdesktop in full screen mode, or in a window? RHEL5
ships with rdesktop 1.6.0, which does not work very well with 2008
R2. I suggest that you try rdesktop 1.7.0 instead. If the problem
persists, try a "strace" on the rdesktop process. That should give you
a clue about what's going on.
Best regards,
