Setting up vpnd

[JoseyWales]

I’ve followed the instructions in the vpnd article to the letter, but it doesn’t work!

When I try connecting via PPTP, I get the message “Authentication failed”.

In the log file, it says (I’ve taken out my IP address):

pppd[529]: PPTP incoming call in progress from ‘nnn.nnn.nnn.nnn’…
mach_kernel: pptp_wan_attach, link index = 0, (ld = 0x1acb304)
pppd[529]: PPTP connection established.
pppd[529]: Using interface ppp0
pppd[529]: Connect: ppp0 <–> socket[34:17]
pppd[529]: Warning – secret file /etc/ppp/chap-secrets has world and/or group access
pppd[529]: MSCHAP-v2 peer authentication succeeded for pflvpn
pppd[529]: MPPE 128 bit, stateless compression enabled
pppd[529]: Could not determine local IP address
pppd[529]: Connection terminated.
pppd[529]: Connect time 0.1 minutes.
pppd[529]: Sent 605 bytes, received 332 bytes.
pppd[529]: PPTP disconnecting…
pppd[529]: PPTP disconnected
pppd[529]: Exit.

Any ideas?

They’re in /etc/ppp/pptp_addresses – but yes, they’re there.

I have followed the instructions to set up the VPND but when I try to connect using a PPTP client I get the following message in the vpnd.log:

2002-11-07 04:56:02 ESTPPTP connection accepted <my IP Address>; leased IP 10.0.1.156 to child 22284
2002-11-07 04:56:02 ESTChild process 22284 quit with exit status 2.

Any ideas?

I have the same error on my log. Has anyone got an answer for this one?

I’ve setup and tested VPN as per your instructions. Works fine. I’m connecting from ‘Mac Internal IP (192.168.50.25)’ to ‘Server Internal IP (192.168.50.100)’. However, when I use the ‘External Subdomain (vpn.server.com)’ with port 1723 (TCP) routed through to ‘Server Internal IP (192.168.50.100)’ VPN connects, then immediatly disconnects.

So…

192.168.50.25 <–> 192.168.50.100 – works
192.168.50.25 <–> vpn.server.com <–>192.168.50.100 – immediate disconnect.

Here’s the log:

Oct 2 15:09:41 theserver pppd[10123]: pppd 2.4.0 started by admin, uid 0

Bearing in mind I haven’t tested this from an external source as yet. That may be the issue (the loop through). But I thought I’d post just incase it could be something else.

Thanks

Just a quickie to say, I went though my setup again, and found that I had 2 typos, and one change that needed to be corrected.

The first was in the – /etc/hostconfig file.
I had a space between the quotes in the line – VPN_ARGS=””
After removing this spac eit worked much better.
The next change was in – /etc/ppp/pptp_service
I had a semi-colon instead of a colon, after my own IP address.
The final one was instead of naming the Password file chap-secrets, i had used an underscore instead of the hypen.

I dont know if this will help anyone, but it would pay to have a close look at your typing. It now works perfectly except that I have to run the VPN Server on a different subnet and bridge it to the network, because of a Allied Telesyn Router that we use for a VPN to other branches.
