[cobalt-users] OFF TOPIC - CHINESE CYBER ATTACK



Speaking of which... What's the proper command to block-out entire blocks of
IP's using IPChains?

I've tried this:

ipchains -A input -i $EXTERNAL_INTERFACE -s 202.93.*.* -j DENY

But IPChains just complains and won't accept the entry so I have to use the
full IP address. What would be the proper syntax to block everything under
202.93.xxx.xxx with IPChains (if possible)?

Thaxs!
David
