I get a error in iptables when i write this code:
Code:
iptables -A INPUT -p udp -m string --algo bm --string "BANNED_CDKEY" --sport 20700 --dport 28961 -j DROP
iptables -A INPUT -p udp -m string --algo bm --string "INVALID_CDKEY" --sport 20700 --dport 28961 -j DROP
Error message:
Code:
iptables: No chain/target/match by that name.
What to do?
