Firstly, ensure that all relevant security patches have been applied. Check http://www.freebsd.org/security/index.html to get more information on how to track these. Secondly, make sure that no unneeded services are running on the machine. If you don't need lpd, don't run it. Same goes for any other service. Lastly, keep a close eye on your logfiles, and if possible implement a firewall using ipfilter or ipfw. -- Wayne Pascoe Things fall apart; the center cannot hold; Mere anarchy is loosed upon the world. - Yeats To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
