But it is not always easy/obvious what name to look for in kernel config file: $ grep -i filter /boot/config-2.6.35.14-103.fc14.i686 ... < quite many results > ... If first looking at kernel source code: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux.git;a=tree;f=net/ipv4/netfilter;hb=HEAD you can confirm the existence of that module file: drwxr-xr-x .. -rw-r--r-- 11796 Kconfig blob | history | raw -rw-r--r-- 2414 Makefile blob | history | raw ... -rw-r--r-- 3158 iptable_filter.c blob | history | raw ... and then you can look up that kernel config file Kconfig: ... 94 # `filter', generic and specific targets 95 config IP_NF_FILTER 96 tristate "Packet filtering" 97 default m if NETFILTER_ADVANCED=n 98 help 99 Packet filtering defines a table `filter', which has a series of 100 rules for simple packet filtering at local input, forwarding and 101 local output. See the man page for iptables(8). 102 103 To compile it as a module, choose M here. If unsure, say N. ... which may not be so obvious to associate with our iptable_filter.c file name. Only then you can get at it precisely: $ grep -i IP_NF_FILTER /boot/config-2.6.35.14-103.fc14.i686 CONFIG_IP_NF_FILTER=y and see that it is compiled in. In other cases it could be worse than that. We depend on the mercy of a kernel hacker with regard to clarity of description and naming conventions.
