RAW socket and CONFIG_FILTER
Hi,
Im doin a project on DHCp client-server setup. i have to use RAW sockets in the code for this. The call PF_PACKET, SOCK_RAW as the first two arguments. The code compiles but when i try to start the Dhcp client, I get an error saying "Make sure CONFIG_PACKET and CONFIG_FILTER is enabled". I tried to build the kernel using a source tree. I found CONFIG_PACKET=y but didnt find CONFIG_FILTER. So i added a line CONFIG_FILTER=y. I got the foll error
Heres a full snapshot of the error :
bash-3.1# make
HOSTLD scripts/kconfig/conf
scripts/kconfig/conf -s arch/i386/Kconfig
.config:384:warning: trying to assign nonexistent symbol FILTER
#

SYMLINK include/asm -> include/asm-i386
ln: creating symbolic link `include/asm' to `asm-i386': Operation not permitted
make: *** [include/asm] Error 1
bash-3.1#
How else can i add it? Is there ne other way out. Im using Fedora 6 with 2.6.20 source tree.

Pls help
Thanks in advance
