Block Skype on Your Network
With the news last week that a subsidiary of China Telecom was blocking Skype, I wondered when the next announcement of someone blocking Skype would come. I didn't have to wait long. At VON this week, Verso Technology announced that they now have a solution for monitoring and blocking Skype. Here is my article on the Advanced IP Pipeline website --
"Verso Appliance Lets Enterprises Block Skype"
According to Verso's man on the show floor, John O'Reilly, blocking Skype is actually a really hard problem. He tells me that Skype jumps around trying different ports and protocols to find a way through your firewall. I'd love to hear from someone who knows if this is really true...

I've heard that this solution is what companies use to forbid skype within their network. China is suspected to use this or a derivative
I think that providing that kind of censorship technology is in total contradiction with the opensource philosophy. Some people suspect Skype to be at the origin of this blocking initiative, for political reasons.
