[pptp-server] 619 Error, problem with pppd

[Vodo Baas]

I am running PoPToP version version 1.0.1 as a server and when I try to 
connect with a Win 2000 computer I get a 619 error stating that the port is 
not connected.  When I check the log I see this:

pptpd[2370]: MGR: Manager process started
pptpd[2379]: CTRL: Client 12.147.193.69 control connection started
pptpd[2379]: CTRL: Starting call (launching pppd, opening GRE)
pppd[2380]: pppd 2.4.0 started by root, uid 0
pppd[2380]: Couldn't set tty to PPP discipline: Invalid argument
pppd[2380]: Exit.
pptpd[2379]: GRE: read(fd=5,buffer=804da20,len=8196) from PTY failed: status 
= -1 error = Input/output error
pptpd[2379]: CTRL: PTY read or GRE write failed (pty,gre)=(5,6)
pptpd[2379]: CTRL: Client 12.147.193.69 control connection finished

If I am reading this right, the call that pptpd uses to call pppd is 
incorrect and causing my connections to fail.

Here is the version information for what I am using:
Red Hat Linux 7.1
Linux Kernel 2.4.17 (From kernel.org)
PoPToP 1.0.1
ppp 2.4.0

I noticed that in the mailing list the version of ppp that most peopl use is 
2.3.8 through 2.3.11 is there a compatibility issue with 2.4.0?  Regardless, 
I have been searching for a while and have not been able to locate any other 
versions of ppp.

Under normal circumstances I do have a firewall in place (through ipchains) 
but when I test the VPN I disable it with this script:

ipchains -F
ipchains -P input ACCEPT
ipchains -P output ACCEPT
ipchains -P forward REJECT
ipchains -A forward -p 47 -j ACCEPT
ipchains -A forward -i eth1 -j MASQ
ipchains -A input -p 47 -j ACCEPT
ipchains -A output -p 47 -j ACCEPT

The last 2 lines dealing with the GRE protocol should be redundant with the 
ACCEPT policy, but I have them in there just to be safe.

The options.pptp (I have it named pptp.options though) file:

lock
debug
auth
+chap
proxyarp

The pptp.conf file:

debug
option /etc/ppp/pptp.options
localip 172.16.0.200
remoteip 172.16.0.225-250
