My friend has a office that has all fedora machines.  They are used because of the VOIP dialer they are hooked up to.  Anyway He asked me today to block all web browsing access for the machines.. as the telemarketers are busy looking at porn and not taking calls... lol  

Can I just uninstall mozilla?

    yep you can uninstall mozilla with

    rpm -e mozilla

    or you can add this lines in the host (correct if are wrong please)

    iptables -A INPUT -p tcp -m tcp  --dport 80  -j DROP
    iptables -A OUTPUT -p tcp -m tcp  --dport 1096  -j DROP

    Accepted Solution

    just blocking port 80 is not sufficient, you need to block *all* ports
    or better just allow the port used by VOIP to the next hop

    If the dialer proggie is ncurses based, you could uninstall X alltogether since pr0n in Lynx takes quite the imagination ;)

    ahoffman is correct...set your perimeter firewall to block all traffic, then only allow what is needed for the VoIP and anything else necessary.  Exactly how to do that will depend on your specific it  a separate hardware firewall, integrated into the main router, none, etc...need a lil more info on how the call center is set up unless you want to go around to every machine individually and set the rules there.
