Quoting Matt Jonkman (mjonkman@infotex.com):
What these vendors may be doing it trying to block access to centralized login or directory servers by known IP ranges... I don't know if that'll be completely effective.
If I understand the protocol correctly, central servers are contacted only on a first run (after install). I(D|P)S systems can have sigs with IP addresses of those servers, but if user X installs Skype client on his corp. laptop at home... it doesn't help much. -- .signature: No such file or directory ------------------------------------------------------------------------ Test Your IDS Is your IDS deployed correctly?
