Subject: Re: bash and linux audit
To: chet.ramey@case.edu
Organization: Red Hat
OK, I released audit 1.4 Sunday which has the logging function for user
commands. It produces audit events like this:
type=USER_CMD msg=audit(01/30/2007 18:23:45.793:143) : user pid=22862 uid=root
auid=root subj=system_u:system_r:unconfined_t:s0-s0:c0.c1023
msg='cwd=/root/test dir cmd=ls -l (terminal=tty1 res=success)'
