If you actual sessions are card based, I wouldn't worry too much about
it. A psuedo session just running yaf-splash isn't going to create
enough load to sway the load balancing algorithm.
If you're worried about them, then run a utaction on disconnect that
will pkill $USER for pseudo sessions.

Kiosk mode enabled with custom uttsc wrapper
My custom wrapper paints a security classification warning and instructions to insert
a smartcard to continue for each pseudo.<MAC> token. For other tokens, it
starts up the uttsc script supplied with SRS.
The pseudo session sits at the banner screen for long periods. I'm not to
concerned about burn-in since LCDs don't tend to have that problem. What I am
looking at is the impact on load balancing within the server group.
Since I use yaf-splash to display the instructions and wait, I thought that
using the -timeout option with a random interval might be a good approach. I
put in the code and assigned the test script to a DTU and my smartcard. Testing
proved that everything works as expected. So what's the problem?
Well, looking at /var/opt/SUNWut/log/messages, there seems to be a lot of activity
related to the kiosk script exiting, the kiosk session getting torn down and a new kiosk
session getting built on another member of the group. Now, that's not really a big
problem for a few DTUs, but I have 1100! I've disabled this feature until I can get a
little help from my friends (sorry, John L.!). SO, what do think? Is this sort of thing
necessary? Am I creating to much churn in my server group for little value? On most days,
I have about 400 running uttsc and 700 with the "idle" DTU display.
Thanks in advance!
