RE: commands "w" "who" & "finger"
No nothing was changed as far as I know. I usually log on as a super user through telnet and there are few others that I have also given access to as a super user. I have not tried the console yet, but what am I looking for.

What's the solution, do I need to rebuid some process or rebooting might solve it.

Assuming I am on the right track (off to a good start - we are!), you could perform a forensic analysis: http://www.l0t3k.org/security/tools/forensic/ ...and/or copy the binary(ies) from a repair/live FreeBSD CD. I am not an expert in this, so there will be others with better advice. ...D ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"

I have not tried the console yet, but what am I looking for. Thanks, Urk. Logging in via telnet exposes your password in cleartext. If it wasn't another 'authorized' superuser who changed things, it could easily be that you've been cracked six ways from Sunday. You should definitely reinstall from CD. It is very strongly recommended that you *always use SSH* for remote login, and that you don't give blanket superuser privileges to others -- give them discrete added privileges with sudo, and/or sink their accounts into a jail environment. -- Greg Barniskis, Computer Systems Integrator South Central Library System (SCLS) Library Interchange Network (LINK) , (608) 266-6348 ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"

Will,
Thanks for the clarification! My own ignorance on the subject led me to
post bad info to the list! I'll have to read up on all this.
Thanks,
