Hi Linda Thanks for the response, >> $ mount /dev/hdc /dev/cdrom >> mount: only root can do that $ strace mount shows a few lines plus the following: open("/etc/mtab", O_RDWR|O_CREAT|O_LARGEFILE, 0644) = -1 EACCES (Permission denied) Then the root window that has tail -f /var/log/audit/audit.log does capture unsuccessful mount with exit=-13 I need /var/log/audit/audit.log to be able to capture the mount event automatically without strace intervention.

Same for me. Betty, what does your audit record look like? As it stands today with syscall auditing, I suspect you'll only get an audit record for mount(2) if the mount command succeeds or if it fails for a reason that the mount command itself isn't checking for. -- ljk > > Cheers, > peter > >> Betty >> >> ---------- Forwarded message ---------- >> From: Betty Man <man.bty(a)gmail.com&gt; >> Date: Fri, Jul 6, 2012 at 10:53 PM >> Subject: capture mount event in /var/log/audit/audit.log >> To: linux-audit(a)redhat.com >> >> >> Hi Everyone, >> >> in RHEL 5.5 kernel 2.6.18-194.el5 audit-1.7.17-3.el5 >> >> Have the following in the /etc/audit/audit.rules >> ## non-privilege users using mount command. >> -a exit,always -F arch=b32 -S mount -F auid>=500 -F auid!=4294967295 -k export >> -a exit,always -F arch=b64 -S mount -F auid>=500 -F auid!=4294967295 -k export >> >> from a general user account >> >> $ mount /dev/hdc /dev/cdrom >> mount: only root can do that >> >> but /var/log/audit/audit.log does not capture this event >> >> Any input is much appreciated! >> >> Thanks in advance >> >> Betty >> >> -- >> Linux-audit mailing list >> Linux-audit(a)redhat.com >> https://www.redhat.com/mailman/listinfo/linux-audit > > > -- Linux-audit mailing list Linux-audit(a)redhat.com https://www.redhat.com/mailman/listinfo/linux-audit
