[pptp-server] connect problem when another connection is using ppp0

[Jason Osborne]

as far as killing my vpn connection, i have not had to kill it at all. i am
running pptpd-1.1.2. when i finish with a connection, it kills the client
itself.

/var/log/messages (pay close attention as i try to bring both up):

what does you pptpd.conf listen to as a IP address??
How did you kill your pptp session, via kill `cat /var/run/ppp-pptp.pid`  ?

HELP.....PLEASE

I don't understand whats wrong. Well I do, but I don't know how to fix it.
First I connect up with the VPN on a system on the LAN. Works great. Then I
kill the VPN connection.

I start the ISDN connection with pppd. Everything works great there. Now I
run ifconfig and get:

	eth0      Link encap:Ethernet  HWaddr 52:54:05:F0:25:90
	          inet addr:192.168.0.1  Bcast:192.168.0.255
Mask:255.255.255.0
	          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
      	    RX packets:33846 errors:0 dropped:0 overruns:0 frame:0
	         TX packets:76141 errors:0 dropped:0 overruns:0 carrier:0
	         collisions:4 txqueuelen:100
	         Interrupt:10 Base address:0xfce0

	lo        Link encap:Local Loopback
	          inet addr:127.0.0.1  Mask:255.0.0.0
	          UP LOOPBACK RUNNING  MTU:3924  Metric:1
	          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
	          TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
	          collisions:0 txqueuelen:0

	ppp0      Link encap:Point-to-Point Protocol
	          inet addr:208.188.23.110  P-t-P:151.164.1.249
Mask:255.255.255.255
	          UP POINTOPOINT RUNNING NOARP MULTICAST  MTU:1500  Metric:1
	          RX packets:1798 errors:0 dropped:0 overruns:0 frame:0
	          TX packets:1796 errors:0 dropped:0 overruns:0 carrier:0
	          collisions:0 txqueuelen:10

Now I start the VPN connection and get this.

	Nov 14 19:57:02 legacycarpets pptpd[21103]: CTRL: Client 4.40.159.70
control connection started
	Nov 14 19:57:02 legacycarpets pptpd[21103]: CTRL: Starting call
(launching
pppd, opening GRE)
	Nov 14 19:57:02 legacycarpets pptpd[21103]: Error reading from pppd:
Input/output error
	Nov 14 19:57:02 legacycarpets pptpd[21103]: CTRL: GRE read or PTY
write
failed (gre,pty)=(7,6)
	Nov 14 19:57:02 legacycarpets pptpd[21103]: CTRL: Client 4.40.159.70
control connection finished

It appears as if pptpd or pppd will not open ppp1 for the vpn to use. How do
I fix this? I have researched the PPPD Howto, the PopTop Website, and the
pppd man file with no luck. I've even searched previous posts. It appears
everyone automatically assumes this works. So what happens when it doesn't?
Does anyone have an answer?
