pptp server woes

[Raan Young <raan@graand-visions.com>]

I'm trying to configure an OpenBSD 2.8 system to function as a PPTP
server, so I can make a VPN connection with a Win98 client...

I've reviewed the archives, etc, and got this far --

Installed pptpd (PoPToP v1.0.1), removed the gre device, and have pppd
configured for noauth.  The Win98 client can contact the server and
attempts to "verify login and password".  After about 30 seconds it
reports an error claiming the server does not respond to network
requests.  Mean while, the pptpd debug output to messages looks like
this...

Jun  5 23:31:35 ozma pppd[19040]: pppd 2.3.5 started by root, uid 0
Jun  5 23:31:35 ozma pppd[19040]: Connect: ppp0 <--> /dev/ttyp2
Jun  5 23:31:35 ozma /bsd: ppp0 output:
ff03c0210101000e05068c3466b507020802
Jun  5 23:32:05 ozma pptpd[7465]: CTRL: Error with select(), quitting
Jun  5 23:32:05 ozma pppd[19040]: LCP: timeout sending Config-Requests

Jun  5 23:32:05 ozma pppd[19040]: Connection terminated.
Jun  5 23:32:05 ozma pppd[19040]: Modem hangup
Jun  5 23:32:02 ozma last message repeated 9 times

The client and server are sitting next to each other, connected by a
10Base-T cable (no modems involved).  Before I removed the gre device
I was getting an error about it (I forget the details), so the pptpd
CTRL error is new -- unfortunately, documentation on pptpd is not very
robust.  Nor do I know enough about ppp to understand the
Config-Requests timeout.

Can anyone give me a clue as to what to look at?

Thanks,
Raan
