Hi, The following command returns no error # iptables -A OUTPUT -m string --algo bm --string show -j LOG But it doesn't log anything when I'm sure package contains 'show'. My system is RHEL4, compiled iptables 1.4.2, I also recompile kernel 2.6.29.1 to support module string with "CONFIG_NETFILTER_XT_MATCH_STRING=m". Does anyone know what the problem is? Thanks.
