<snip> > 9141 /lib/modules/2.6.26-1-amd64/kernel/net/ipv4/netfilter/ipt_ecn.ko > 9975 /lib/modules/2.6.26-1-amd64/kernel/net/ipv4/netfilter/ipt_ECN.ko > 8762 /lib/modules/2.6.26-1-amd64/kernel/net/ipv4/netfilter/ipt_ttl.ko > 9232 /lib/modules/2.6.26-1-amd64/kernel/net/ipv4/netfilter/ipt_TTL.ko I just went and looked at the code, and my guess, based on http://lxr.linux.no/linux+v2.6.29/net/netfilter/Makefile http://lxr.linux.no/linux+v2.6.29/net/ipv4/netfilter/Makefile and a quick glance at http://lxr.linux.no/linux+v2.6.29/net/ipv4/netfilter/ipt_ecn.c http://lxr.linux.no/linux+v2.6.29/net/ipv4/netfilter/ipt_ECN.c is that the lower case modules (such as ipt_ecn.ko) are those responsible for matching rules (e.g., matching an ECN flag) while the upper case modules (ipt_ECN.ko) are responsible for targets (e.g., modifying the ECN flag). As for Googling, my first attempt to search for "netfilter module naming convention" yielded http://jengelh.medozas.de/documents/Netfilter_Modules.pdf at #2 from the top, and the very beginning of this document supports my guess.
