With IPTables.

rsk

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

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

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

rsk

@joodle

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

Running SSH on default port? Tsk, tsk...
