HELP! UNDER ATTACK!

[SHSaeed]

We've been under attack for a couple of hours now. I tried to block the attacker with [b:4f8a97f080]iptables -I INPUT 1 -s xxx.xxx.xxx.xxx -j DROP[/b:4f8a97f080] but I get &iptables v1.2.5: can't initialize iptables table `filter': iptables who? (do you need to insmod?) Perhaps iptables or your kernel needs to be upgraded.& I also tried to use /sbin/route to block them but it's of no use!!! How can I block these attacks, they're causing Apache to reach maxclients (which is set to 256).

Please HELP!!!!!!!!

Here are the IPs that were attacking if anyone's interested...

24.185.148.33
68.36.123.27
66.76.93.157
68.11.36.65
24.205.209.230
12.220.192.165
68.5.224.66
4.46.204.175
24.76.66.39
66.189.215.241
128.111.71.114
212.202.128.213
4.46.204.175

We finally got our datacenter to null route the listed IPs.

Found a way to do it ourselves...

ipchains -A input -s &IP&/255.255.255.255 -d 0.0.0.0/0.0.0.0 -j DENY

By replacing &IP& with the attacking IP you will block them on all ports.
