IP-Filter on Linux 2.0.31
|
|
-------------------------
|
|
|
|
NOTE: I have *ONLY* compiled and created patches for using IP Filter on
|
|
Linux 2.0.31. Any other kernel revision may need seprate patches.
|
|
Also, I've only tested on a x86 CPU so I can't make any guarantees
|
|
about it working on Sparc/Mac/Amiga.
|
|
|
|
First, you should do a sanity check of your system to make sure it will
|
|
compile IP Filter. You will need a "libfl" and a "libelf". If you don't
|
|
have these, install them before proceeding.
|
|
|
|
The installation and compiliation process assumes that Linux 2.0.31
|
|
will be in the /usr/src/linux directory and that all the symbolic links
|
|
in /usr/include match. /usr/src/linux may be a symbolic link too, but
|
|
it must point to a 2.0.31 kernel source tree.
|
|
|
|
The first step is to make the IP Filter binaries. Do this with a
|
|
"make linux" from the ip_fil3.2.x directory. If this completes with
|
|
no errors, install IP Filter with a "make install-linux".
|
|
|
|
Now that the user part of it is complete, it is time to work on the
|
|
kernel. To start this off, run "Linux/kinstall". This will patch your
|
|
kernel source code and configuration files so you can enabled IP Filter.
|
|
You must now go to /usr/src/linux and configure your kernel using one of
|
|
the available interfaces to enable IP Filter. IP Filter will be presented
|
|
as a three way choice "y/m/n" - select "m" to enable it. Save your kernel
|
|
configuration file, rebuild, install and reboot with the new kernel.
|
|
|
|
When you've rebooted with the new kernel, you should be able to load
|
|
IP Filter with the command "insmod if_ipl". All going will, you will
|
|
see a message like this on your console:
|
|
|
|
IP Filter: initialized. Default = pass all, Logging = enabled
|
|
|
|
indicating that IP Filter has successfully been loaded into the kernel
|
|
and is awaiting.
