[pptp-server] GRE: read error: Protocol not available

[Jamie Miller]

Howdy folks,

I'm running kernel 2.4.9, pptpd-1.1.2 (tried the stable version too), and
ppp-2.4.1.

I'm unable to connect my pptpd server from either Win98SE, or Win2K. The logfile
output follows:

/var/log/messages:

pptpd[656]: CTRL: Client 200.200.190.160 control connection started
pptpd[656]: CTRL: Starting call (launching pppd, opening GRE)
pppd 2.4.1 started by root, uid 0
pppd[657]: Using interface ppp0
pppd[657]: Connect: ppp0 <--> /dev/pts/1
pptpd[656]: GRE: read error: Protocol not available
pptpd[656]: CTRL: PTY read or GRE write failed (pty,gre)=(4,5)
pptpd[656]: CTRL: Client 200.200.190.160 control connection finished
pppd[657]: Modem hangup
pppd[657]: Connection terminated.
pppd[657]: Exit.

/var/log/pptpd.log:

Any help would be appreciated,

Thanks,
