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

If either can be set, what's the different?
Again, what's the different if set option... (1 Reply)

To create RAW socket in Unix/Linux why should one have root permissions?

create_makefiles
CREATE_MAKEFILES() CREATE_MAKEFILES()
NAME
create_makefiles - Recreates all Makefiles beneath a directory
SYNOPSIS
create_makefiles [dir]
DESCRIPTION
create_makefiles recreates all Makefiles in dir and its (recursed) subdirectories from the corresponding Makefile.am templates.
This script must be run from the toplevel directory (the one containing configure). This script saves time compared to re-running configure
completely.
If the source directory is different from the build directory (see the environment variables below), it will be assumed that each
Makefile.am and Makefile.in belongs beneath the source directory and that each Makefile belongs beneath the build directory.
This utility is part of the KDE Software Development Kit.
ENVIRONMENT
One of the following variables (but not both) should be set if the source directory is different from the build directory. If the build
directory is simply a subdirectory of the source directory, the simpler variable OBJ_SUBDIR should be used.
OBJ_SUBJDIR
Indicates that the build directory is in the given subdirectory of the source directory. For instance, if the source directory is
kdesdk and the build directory is kdesdk/obj-i386-linux, then OBJ_SUBDIR should be set to obj-i386-linux.
OBJ_REPLACEMENT
A sed expression that is used to transform the source directory into the build directory. For instance, if the source directory is
kdesdk/obj-i386-linux, then OBJ_REPLACEMENT should be set to s#kdesdk#kdesdk-obj#.
