[pptp-server] pppd and redhat 7.2

[Jerry Vonau]

Chris:
---------
I've configured it to just use CHAP, Optional encryption,
PPTP VPN.
---------

If you have not patched pppd/kernel, then set the client up
to be able
to use no encryption, that is the level of the server at
this point.

With win2000, there is an option to use "no encryption
allowed"
I'm not sure if that is available with XP, might be KB at MS
for 
that sort if thing if it is not present. 

What version of pppd is installed? You may have to upgrade
2.4.1 
anyway, as others people on the newsgroup comp.protocols.ppp
have
said that redhat's version is a little broken out of the
box.
I think it has problems parsing any options.xxx files.
Hope it helps.....
