I once wanted to check every printer to see if they worked, so I made a small script which did echo $printer|lp -d$printer This "printer" did a chmod on /$inputfile. As there wasn't any input file when lp got its input from stdin, it chmod / instead, so as in your case, only root could log in. 4 hours of downtime, and a bill from support, because I did the damage. I think I succeded to brush it off on the company who made the spooler... </ANECDOTE MODE> Leif Neland leifn@image.dk --- |Fidonet: Leif Neland 2:234/49 |Internet: leifn@image.dk To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
