Unless you have a situation where you=20 absolutely have to block, ie, you have users that won't listen to a kind=20 request, ie, school kids, your kids, management, I would not pick blockin= g as=20 a strategy, instead, tell them that the use of IM services is not allowed= on=20 the network, and that infringement will be considered time not spent on=20 business activities, take it off their salaries, they'll stop trying righ= t=20 away. --=20 Willie Viljoen Freelance IT Consultant 214 Paul Kruger Avenue, Universitas Bloemfontein 9321 South Africa +27 51 522 15 60 +27 51 522 44 36 (after hours) +27 82 404 03 27 (mobile) will@unfoldings.net To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
