MPPE Encryption HOWTO OS: Linux - Debian Woody Files Needed.

ppp v2.4.2

linux kernel (I used 2.4.25)

libpcap development files

  • apt-get install libpcap-dev

ppp-2.4.2 mppe patch.

gcc-2.95 and make etc, all the tools to build a kernel.

apt-get install libpcap-dev cd /usr/src/ wget http://ccache.samba.org/ftp/ppp/ppp-2.4.2.tar.gz wget http://www.kernel.org/pub/linux/kernel/v2.4/linux-2.4.25.tar.bz2 wget http://pptpclient.sourceforge.net/mppe/ppp-2.4.2_cvs20040216-linux-mppe.tar.gz tar -zxf ppp-2.4.2.tar.gz tar -jxf linux-2.4.25.tar.bz2 tar -zxf ppp-2.4.2_cvs20040216-linux-mppe.tar.gz

:;If you like you can symlink /usr/src/linux to /usr/src/linux-2.4.25/ This is usefull because some things that require kernel source to build look here for it.

ln -s /usr/src/linux-2.4.25 /usr/src/linux cd ppp-2.4.2_cvs20040216-linux-mppe/ ./mppeinstall.sh /usr/src/linux-2.4.25/ cd ../linux-2.4.25/ make menuconfig

(or whatever way you prefer to set up your kernel config) :;Build support for all ppp related modules as modules, It will fail for some unknown reason if you dont compile as a module.

build the kernel and modules as usual, install it and reboot. Dont forget to run lilo

or whatever. Fixing up a broken kernel build is beyond the scope of this document. For now I'll assume that all has been sucessfull and you are running your new kernel.

cd /usr/src/ppp-2.4.2/ ./configure make make install

Your ppp should now have support for mppe encryption a quick test to see if pppd is ready.

strings /usr/sbin/pppd |grep mppe

next load the kernel support

modprobe ppp_mppe

to make it easier put these into /etc/modules or add these lines to /etc/modules.conf

alias ppp-compress-18 ppp_mppe alias ppp-compress-21 bsd_comp alias ppp-compress-24 ppp_deflate alias ppp-compress-26 ppp_deflate

This should make them load automaticly when they are needed.

Now configure your pptp connections, or whatever you needed this support for.
