[pptp-server] pptp server and Win98 -- *sigh*

Hi all,

I'm new to this list so be kind even though I'm asking a question that's 
probably been answered a thousand times

I recently set up pptp (1.0.0) on an old 486 (gotta do something with the 
old hardware) running linux 2.0.35
pppd is version 2.3.10 with the appropriate patches

NT4.0 connects just fine 
Win98 (not SE) get's an error 720 - something about not being able to 
negotiate protocols

I *did* check out the archive, but I could not find a complete answer - 
most solutions seem to center around de-installing and re-instlling VPN in 
Win98 and applying the DUN40.exe patch from M-$oft -- been there, done 
that, still no good.

it seems that authentication is (finally) working - what seems to be 
sticking is the negotiation of encryption

here's a 'dump' of /var/log/debug with a few (guesses) comments thrown in

Can anyone tell me what I can try next or what I should be looking at?

hmmm - ppp_lzscomp.c looks incomplete so I don't have a ppp_lzscomp.o 
module

OK - so Win98 doesn't like bsdcomp ...

Aren't we all in agreement to use mppe (40 bit??) 'compression' now?
