I have a shell server that I am a little worried about because of script kiddies :-( ---Mike ------------------------------------------------------------------------ Mike Tancsa, tel +1 519 651 3400 Network Administrator, mike@sentex.net Sentex Communications www.sentex.net Cambridge, Ontario Canada To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
