I want block a certain packets with some text on it.
Im using iptables 1.3.5 and i want do the follow:

iptables -I FORWARD -p tcp --dport 1863 -m string --string "someuser" -j DROP

And i get this error:

iptables v1.3.5: STRING match: You must specify `--algo'

Why i get that problem?

Thanks.

  1st of all, use the string module in the raw table. Then:

  -m string --string "your string" --algo bm
