[pptp-server] Configuration Nightmares

[Johnny L Wales]

Hello! I'm having some serious problems getting PoPToP working correctly
on RedHat 6.1 with a Win98 client. Here's the deal: I set up a connection
on the windows machine exactly as specified on the PoPToP web page. I've
checked and rechecked this. Further, I set up the Linux machine running
the pptpd exactly as specified on the web page. Everything is an almost
exact copy of what is recommended. 

When I try to connect from said 98 machine, the logs on the redhat machine
look like this:
Mar  2 11:34:05 mail pptpd[3307]: CTRL: Client 199.174.132.14 control
connection started
Mar  2 11:34:05 mail pptpd[3307]: CTRL: Starting call (launching pppd,
opening GRE)
Mar  2 11:34:05 mail pppd[3308]: pppd 2.3.11 started by root, uid 0
Mar  2 11:34:05 mail pppd[3308]: Using interface ppp1
Mar  2 11:34:05 mail pppd[3308]: Connect: ppp1 <--> /dev/pts/1

At this point, the windows machine throws up an error box saying: "Error
645: The microsoft Dial-up adapter is in use or not responding properly.
Disconnect other connections and then try again. If this problem persists,
shut down and restart your computer." Gotta love that microsoft error
reporting! So helpful! :/ Upon closing this dialog box, the following
stuff shows up on the linux machine's log files:

Mar  2 11:34:10 mail pptpd[3307]: CTRL: Error with select(), quitting
Mar  2 11:34:10 mail pptpd[3307]: CTRL: Client 199.174.132.14 control
connection finished
Mar  2 11:34:10 mail pppd[3308]: Modem hangup
Mar  2 11:34:10 mail pppd[3308]: Connection terminated.
Mar  2 11:34:10 mail pppd[3308]: Exit.

And that, as they say, is pretty much that. I think it's relevant to note
that while the error message claims the "dial-up adapter is in use or not
responding correctly", the VPN Connection is set up to use the VPN adapter
and not the standard dialup adapter.

Another thing to note: The win98 machine is connected via modem to an
outside ISP, rather than already being on the LAN here. 

Any ideas what exactly is wrong here?
