I use SRSS 4.2 on Ubuntu 9.10 for a classroom in a university.
I am trying with utpolicy to desactivate hotdesking sessions for
non-card access.
Maybe i should explain a little bit more :
I want that students use their normal login/passwd to open ubuntu
session (non-card) with gdm and i don't want to have hotdesking feature
applied on this. Because if "something or somebody" close the session
(like a network or electric cut), when the DTUs comes up again, the
student's session is still ed open.
Ah, that clarifies things. Usually 'hotdesking' refers to mobile
sessions, i.e. that a session can be disconnected from its initial
client and resumed on any client. You configuration already disallows
this for non-card sessions.
You want user sessions to be ended when a DTU is disconnected. This does
not happen automatically for Sun Ray session. Most people wouldn't like
losing their unsaved work for any network hiccup. But when sessions
continue to run, there should be a way to reconnect to them - otherwise
there is no way to log out or otherwise end them except having an
administrator kill the session from outside.
For this reason SRSS does not offer a built-in facility to disable
'reconnectability'.
But you can achieve the effect you want by running a utaction(1) process
for every session that terminates the session upon disconnect. You
should consider to use a non-zero timeout, so that very short accidental
disconnects don't terminate the session right away.
The best place to do this is probably to place a shell scriptlet in the
xinitrc.d directory which runs
/opt/SUWNut/bin/utaction -e -i -d "kill $$" [-t <timeout>] &
(here $$ should resolve to the PID of the session process sourcing the
xinitrc.d scripts)
But i want that card users would be able to keep the hotdesking ... (for
the administrators or teachers with cards)
For this your scriptlet need to check the session token
($SUN_SUNRAY_TOKEN) before launching the utaction. If the token starts
with "pseudo.", then it is a non-card session.
Do you think it is possible ?
Yes, but you need to install your own script to do it.
