Re: howto block yahoo messenger

[Kunal Walia <kwalia@xxxxxx>]

Also,
I still fail to understand how blocking http://pager.yahoo.com would prevent
the Messenger service from working 'cos that server is a mere http server
thats all. Messenger doesn't use it to connect to its database or nething.
And though Messenger uses port:80 like u said......it also needs port 5050
to effectively "send-messages" across the service.

Something else that this brings up: Even if u do block the port the user can
still configure the service to run on some other port (well not in this
particular case but on a more general basis).
