Unable to connect - where to find server log files?

[kurtharriger]

Currently attempting running it in a boot2docker with minimal changes to see if I can get it to work. When I first tried to build the image I had problems with python package so I changed it to use debian:wheezy instead, but after that was able to build and run the image. I left the username password as student howdyhowdy and shared secret as howdyhowdy to test it, but I'm unable to connect with following error:

"The L2TP-VPN server did not respond. Try reconnecting. If the problem continues, verify your settings and contact your Administrator."

Enabling verbose logging on OS X I get the following in /var/log/ppp.log on the client.

I tried to override the docker start to just be /bin/bash so I could run the run script in background and look around for any logs on the server, but I couldn't find the logs on the server. Where should I look?

Also here is the error I got building the image on ubuntu:12.04, I would send a pull request for my changes, but I wanted to get it working first. My fork is here: https://github.com/kurtharriger/docker-l2tpipsec-vpn

Hey Kurt

I haven't messed with the repo in a while and I commend your efforts. The repo in its current state represents my best effort on this. I spent a ton of time trying to get it working, but ultimately wo success.

I'm really sorry I can't be more help. I wish you the best of luck and let me know if you get it working.

Thanks for the quick reply. I did make a bit more progress I suppose but still unsuccessful.

While I can echo "hello" > /dev/udp/192.168.59.103/1701 and get xl2tpd to spit an error when running in foreground, when attempting to connect from os x vpn client it seems to receive nothing. I'm thinking perhaps there some initial communication that supposedly needs to happen first, but I'm not sure.

I might try the docker openvpn again, but was looking for something that was easy to setup from the client side and didn't require installing additional vpn clients. Thanks!

I was looking to setup native vpn, instead of open vpn, for the same reasons.

I believe that I solved all the dependency issues and now the issue lies at the networking level. Forwarding the right ports and connections from the external interface, to docker, the container, and then back out that stack to the Internet was very hard to debug.

Like I said, never got it working. Good luck!
