[TriLUG] PoPToP connection issue

[Ryan Wheaton]

hey guys,

i'm lost, basically cause i've never set up a VPN server before, but 
i'm trying to set one up using PoPToP on WhiteBox Linux.  I've patched 
the kernel and installed all the right stuff and edited the right conf 
files per the RedHat installation instructions on the poptop.org 
website.  But, when I try to connect a Win2k client to the server I get 
this:

Error 619:  The specified port is not connected.

here's what is in the logs:

Jan  7 09:44:38 hostname pptpd[1823]: CTRL: Client home.ip.add.ress 
control connection started
Jan  7 09:44:38 hostname pptpd[1823]: CTRL: Starting call (launching 
pppd, opening GRE)
Jan  7 09:44:38 hostname pptpd[1823]: GRE: 
read(fd=5,buffer=804d5a0,len=8196) from PTY failed: status = -1 error = 
Input/output error
Jan  7 09:44:38 hostname pptpd[1823]: CTRL: PTY read or GRE write 
failed (pty,gre)=(5,6)
Jan  7 09:44:38 hostname pptpd[1823]: CTRL: Client home.ip.add.ress 
control connection finished


this doesn't make much sense to me.  I don't have much experience with 
GRE, so I'm a little lost.  The only ideas that I have is to disable 
GRE in the kernel and recompile, but, I'm working from home today (to 
test the VPN) and don't really wish to recompile and test a new kernel 
remotely :)


thanks for help in advance.
