I was just wondering if there was a package/script out there that could be used to notify the sys. admin every time a user logged into a debian system.
The simplest two ways, as was already noted, is to add something to /etc/profile or some other script that is called at login time that will notify you in some or other manner, or to parse your log files. I remember years ago there used to be a program similar to xconsole that would highlight certain lines for you. Strangely enough, someone else asked me about this too a while ago. We talked about doing this using pam. A couple of years ago I wrote a simple pam (pluggable authentication module) that does session management -- whenever a user logs in or out it calls a script. Initially I only cared about session end, I used it with kdm at the time so that when a user's kde session ends it would kill off certain processes which at the time were known to "hang arround in the background", and unmount floppy drives. We used it in a lab setting at a university. This little module quickly expanded, today it does both session and authentication management and can hook into login or logout. It is called pam_script, non-officially renamed to libpam-script to match debian policy, and there are two places you can get it, on mentors.debian.net, or on freshmeat (which will redirect you to some google address that currently only hosts a subversion repo). Unfortunately it isn't part of debian (yet). Sponsors welcome. http://mentors.debian.net/debian/pool/main/l/libpam-script/ I was thinking that a very cool way to implement this into the system would be to use dbus: when a user logs in this would inject an signal into the dbus system, and an interested application can listen for this event somewhere and display it on screen. This is rather an elaborate idea, but one that can certainly be extended to other uses. You could write a generic send and receive program that can be used in other ways as well (or use the dbus-send and dbus-viewer programs). An example of writing dbus server and client can be found here: http://www-128.ibm.com/developerworks/opensource/library/l-dbus.html If I had more time I'd probably do it too, for the moment I put this idea out there in case someone feels like toying with it.
