Guys I'm neither a PAM fan or guru but without doubt this is comprehensivley handled by PAM. I also have no doubt that you would need to write your own module. But a suitable module, using a database would work well and all the time and effort channeled into scripting hacks would be available for ltsp for all future needs of a similar nature (whereas the hacks stay as inconvenient hacks) James - This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.

Maybe this will help others out. Basic Idea: User is give XX hours "allowance" for the month. (say with your request earlier, 30 days x 1 hour each = 30 hours). Using the idea above, user can get on for 60min at a time, then kicked off. BUT they can then get back on. (that is where my idea kind of breaks down from your original post) 1) When USER_X logs in, time gets recorded in /tmp/USER_X-on (make sure user does not have write access to this file) 2) At log off, total time is calculated. If user waited to be kicked, then of course this time would be 60 min. So part of the "sleep" line above you can just have it assume 60 mins, without doing the math. 3) Total time used recorded in /root/USER_X-used (or some other secure place) 4) At the beginning of the script, you could have an IF/THEN that checks the /root/USER_X-used file. If it is less then the allowance, then X is started with the default .xsession If it is greater-then or equal to, then X is started with your own special .xsession file that posts a message about time used up already. (xsession is assuming X only logins, you may want/need to use a different startup script) I know this is not exactly what you wanted, but I think it should be a bit easier to script up. The idea of including a limit of 1 hour PER day I think would add a large bit of complexity to the script(s). -- http://gentgeen.homelinux.org # Associate yourself with men of good quality if you esteem your own reputation; for 'tis better to be alone then in bad company.- George Washington, Rules of Civility - This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.

[Ltsp-discuss] Ltsp time counter
Dear All, I'm looking for help regarding time controlled logins to ltsp workstations. I have ltsp 4.2 with Fedora Core 6 installed, authentication is done through LDAP. This is for a proposed public access solution at one of our educational institutions, with about 8000 students. The plan is to start off with a 30 station solution and than expand at a later stage. What remains a big issue is that with these limited resources available, we would like to give as many students as possible access to a workstation per day. Which means that we need to limit the time these guys spend on a workstation to maximum 1 hour per day, they should not be able to login again for that day, inactivity logout, say after 10 min, etc I know there is no easy solution nor off the self solution to this, but could be done with some scripts. Now this is where the problem comes in. My scripting is not great, not even at entry level, but I know somethings could be done with linux through "last", finger, etc. I need you help, any suggestion would be much appreciated.

Re: [Ltsp-discuss] Ltsp time counter
Rudolf, I have set up timed LTSP systems in a number of public libraries for 4 or 5 years now. The system uses a mysql back end to track the time, number of sessions per day, etc. and xscreensaver as the locking mechanism, with a bunch of scripts that do the heavy lifting such as warnings, time renewals, etc. Some problems: This isn't exactly what you are looking for. You probably want a new session for each user whereas in the libraries, the same session is used all day. Some modifications would be needed to log the student out instead of just locking the session. There is also the problem of a student losing their work if they ignore the warning messages, don't save their work and the system logs them out. Everything is GPL'd but the documentation is virtually non-existent. If you are interested I can post everything on the Web and you can have a whack at it. I'd be glad to help where I can.
