i have blocked myspace. here's how to do it.
echo "127.0.0.1 www.myspace.com" | sudo tee -a /etc/hosts
i dont believe the person is smart enough to use instant message from a
website, but if i need to, ill start blocking all those websites. how can i
use block the instant messengers with iptables? be more specific on how to
do it please. what's the command? yahoo uses port 5050 for logging in with
the server for IM, so how can I block that? There should be one command to
do it instead of installing squid and a bunch of other software. I just
blocked websites without installing squid, so please don't suggest it.
