Re: Messenger services

["R. DuFresne" <dufresne () sysinfo com>]

The difficulty here is that many, if not all these applicatiuons now play
a 'find an open port' game, port blocking no longer works for most these
toys.  What has been working is to find out what servers the users have to
login to and block access to those machines.  For AIM, one should get
decent results blocking these machines:

 205.188.7.168
205.188.7.172
 205.188.7.176
205.188.7.164


Thanks,
