The mail part (phpmail) will be easy; I don't know yet how to trigger and pass parameter to this script or redirect info to a file (that I then send by email). Thanks. A cheesy way to do that is to use a popen (tail -f /var/log/auth.log, r) and then read that. It will give you every login regardless of ssh, telnet etc. You could then generate the emails from that. I have no idea just how resource intensive this might be.

$ tail -F -n 0 /var/log/auth.log Definitely use the -F rather than -f option as it will handle log rotation ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org
