The ip_wccp module linked from the Squid FAQ works with any Linux-2.4
release.

You can only have one installed at a time.

You can select if you want to use the WCCP-specific ip_wccp module, or
a patched gre module with support for WCCP added.

What have you tried, and what error do you get.


A almost fail-safe method of building the ip_wccp module is to

1. Build and install your own kernel. Take note what the gcc lines
typically look like while running "make modules".

2. Reboot into this new kernel to verify that it works fine before
continuing.

3. Compile the ip_wccp module using a command line which looks a lot
like the line noted in step '1' above, but specifying the ip_wccp.c
module instead of the other module which the line was for.

3. Install the resulting ip_wccp.o module in
/lib/modules/<kernelversion>/net/

4. Run "depmod -a".

5. Run "modprobe ip_wccp" to load the ip_wccp module.

Henrik, I got your post. I have chosen to go with the gre tunnel as
that already has a module in place and I can run all the commands as
designated in the FAQ. At this point, I assume that I need to set up
iptables on my server to forward the requests and I also guess I need
to set up my router with the proper WCCP statements?

What I am wondering at this point is whether or not the router talking
WCCP will know how to communicate with my squid server talking gre.
Am I missing something here?
