Indeed, but in this case they've blocked everything except HTTP(S) and THAT is also increasingly common: block all ports and wait for users to scream. Screaming sometimes gets outgoing SSH back, but hasn't in this case. So, really, that's the scenario I was talking about being fairly common now: pretty much everything blocked. I know of at least two universities now who do this for their wireless networks. -Mary -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html
