[pptp-server] pptpd/pppd/mppe + kernel 2.2.19

Wed May 30 12:19:56 CDT 2001

The deal is... Untill recently... everything but true ppp support was kept
as a module to the kernel. So deflate and bsdcomp moduels were only
allowed to be modules.  This has Changed recently.... So in theory, I
guess you could build a monolithic kernel supporting mppe... How... Is
beoynd me at the moment... look at the patch that patche's the kernel for
mppe support.
