The list went through this several times already.
Blocking ports 4444, 5555, 6666, 7777 is useless.. since Beta6, Napster =
has
been able to work on ANY port, INCLUDING 80.. so to kill Napster, you =
would
have to kill all access to http/tcp80.. NOT good. Blocking the IPs is =
the
best and most thorough solution at this time.
Also, besides blocking the access to the main Napster sites will block =
most
users, and for those that go around it, there should be a user policy in
place. It is not totally your job to govern what the users do and do =
not
do.. the users should also be held responsible. Put a political policy =
in
place, and if it is broken by a user by using something such as opennap,
discipline from management will solve this issue.

Blocking these IP addresses will only block users from accessing the =
main
napster servers and will not block access to other napster servers, such =
as,
opennap, which can be found easily by using the napigator program. The =
best
way to block Napster is to block the ports that the client uses which =
are
4444,5555,6666,7777. Don't quote me on these ports because I can't find =
my
documentation at the moment, but I think they are right.
