VPN setup

requirements:

Kernel 2.4.19
PPP 2.4.1 - ftp://cs.anu.edu.au/pub/software/ppp/
PPTP Server 1.1.3 pptpd-1.1.3.tar.gz
Kernel Patch for MPPE support linux-2.4.19-openssl-0.9.6b-mppe.patch.gz
PPP Patch for MPPE support ppp-2.4.1-openssl-0.9.6-mppe-patch.gz
I suppose you also need openssl-0.9.6, but I already had it on my RH 7.2 box.

unpack all archives
build kernel:

cd /usr/src/linux
patch the kernel: patch -n1 -i ../linux-2.4.19-openssl-0.9.6b-mppe.patch
make mrproper
make menuconfig
make dep
make bzImage
make modules
make modules_install

build ppp:

cd /usr/src/ppp-2.4.1
patch ppp: patch -n1 -i ../ppp-2.4.1-openssl-0.9.6-mppe.patch
./configure
make
make install

build pptpd:

cd /usr/src/pptpd-1.1.3
./configure
make
make install
