Starting "Script" when user logs on.

Starting "Script" when user logs on.

[Md Shanto]

Hi all,

I am trying to force "script" for logging all text I/O activities at
the moment user logs in. Most of the users are running bash at this
moment.

Initially I tired with "ttyrec" a tty recorder and failed, as it says
"Out of pty's - Terminated". Now, I tried something like below:

------------------
#!/bin/bash -l
USER=`whoami`
LOGTIME=`date +%Y-%m-%d-%H:%M:%S`
/usr/bin/script -q /var/log/commlog/$USER-$LOGTIME
------------------

and assigning this script in /etc/passws. This script will log scripts
with time stamp in /var/log/commlog/.

what happen is: when user logs in the process becomes a loop and I see
lot of script instances are running.

Any idea.

I don't think script will help you, as even if you get it working, your  
users can just Ctrl-D out of it. Unless you trust your users.
Once upon a time I used ttysnoop:

Unless you can get this script running as some kind of wrapper to bash. 
  Then you can change the default shell for your users to point at this 
wrapper ..

use screen to start their shell and turn on logging in screen.

I think (not sure) that script also tries to start the default shell for the
user and calling the script in the process...

Perhaps you could try a line like:
/path/to/script ; exit
at the end of your /etc/profile?


Not sure if it'll work, though.

Unless these processes aren't being cleaned up (in which case, you
will probably have over a hundred stale ttyrec processes), it may be
that ttyrec was compiled for BSD-style ptys but your system is using
Unix98 ptys (or vice-versa).

Apart from anything else, you should probably use "exec" for the last
statement, i.e.:

	exec /usr/bin/script -q /var/log/commlog/$USER-$LOGTIME

This causes the "script" process to replace the bash process running
the shell script, rather than leaving the bash process hanging around
until script exits.
