Debian MPPE HOWTO, build kernel module
SUPERCEDED, OBSOLETE AND NOT MAINTAINED.
26th May 2004
These are instructions for building the MPPE kernel module on Debian GNU/Linux, using the kernelmod package. No reboot is required. No package is generated.
Log in as root
Note: the commands below were tested after logging in as root. We know they fail if you merely su, because doing that may leave your PATH without a reference to /usr/sbin. Use su - to force a root login.
Install kernel packages
The kernel-source and kernel-headers packages for the currently running kernel are needed for the build process:
| # apt-get install kernel-source-`uname -r` kernel-headers-`uname -r` |
| Note: the above command is a suggestion, for some kernels you will
need to strip a revision number or processor type from the uname
-r string. Check with the documentation for the kernel you are
running, and use apt-cache search kernel-source.

Download kernelmod
Download the package kernelmod-0.7.1.tar.gz from the Poptop project's files list. Then install it like this:
| # tar xfz kernelmod-0.7.1.tar.gz # cd kernelmod # ./kernelmod.sh |
Note: it is important to avoid the -o option, for compatibility with the version of PPP used by Debian.
Test MPPE Module
Test that the MPPE module loads on request:
| # modprobe ppp-compress-18 && echo success |
If the word "success" appears, then the module was loaded successfully. A warning may appear:
| Warning: loading /lib/modules/2.4.20-8/kernel/drivers/net/ppp_mppe.o will taint the kernel: non-GPL license - BSD without advertisement clause See http://www.tux.org/lkml/#export-tainted for information about tainted modules Module ppp_mppe loaded, with warnings |
This is expected and does not change the operation of the module; the test may still be successful.

You have now installed MPPE support. Return to the Installation step in the main HOWTO.
