    @joodle

    Is this on a vps? if so xen or openvz?

    Regards

  • @joodle WHAT ARE YOU PLANNING? All these questions.. what's it leading up to eh?

    Don't worry, i don't think he's going to start a hosting service or so :D

    Port 28960 is CoD 4 so he probably just wants to protect his CoD server.

  • @rsk openvz
    @AsadHaider i keep getting dos attacks from like 6-8 mb/s and i want to close all ports now except the ones i need to use

    speak to your host for openvz, unless if they actually allow you to control your own iptables from within your VPS.

    If you have iptables, you could something like

    iptables -N WHITELIST
    iptables -A INPUT -j WHITELIST
    iptables -A WHITELIST -p tcp -m tcp --dport 21 -j ACCEPT
    iptables -A WHITELIST -p tcp -m tcp --dport 22 -j ACCEPT
    iptables -A WHITELIST -p tcp -m tcp --dport 28960 -j ACCEPT
    iptables -A WHITELIST -p tcp -m tcp --dport 9987 -j ACCEPT
    iptables -P INPUT DROP

  • Easier using csf.

  • @garrett thanks, tried that
    i hope that helps...
