[pptp-server] encryption - doesn't work under linux?? but under w2k - please read

[Phil Van Baren]

Right, it is a patch to the kernel module.  The example you mention patches
the kernel module in the pppd source directory before it is copied into the
kernel source tree.  If you have already copied the updates into the kernel
source tree (i.e. run 'make kernel' in ppp directory) you should apply the
patch to the ppp_mppe.c file in /usr/src/linux/... or run 'make kernel'
again after applying the patch, and verify that the change gets propagated
into the ppp_mppe.c file in the kernel source.
