using openvpn via an ssh tunnel via http proxy

This is how to use openvpn via an ssh tunnel via http proxy on windows to create a network route between 2 LANs or for you to access your office computer directly from home.

I'm using Windows at the office and Linux at home. You will need Openvpn 2 and putty for this. This is theoratical and should not work, however for some reason you decide to try this and have it work, Let me know. However if you publish your openvpn service on port 22, this should have no issues. Just skip the following ssh step.

To start ssh tunnel with putty. make sure that the http proxy is configured with a keepalive and in the SSH section create a new rule that uses L1194 localhost:1194

The server command you can run on your linux box at home:

openvpn --port 1194 --proto tcp-server --dev tun --comp-lzo --ifconfig

The client command you run on the workstation in the office is:

openvpn --remote localhost 1194 --http-proxy 8080 proxy.txt --http-proxy-timeout 5 --dev tun --proto tcp-client --ifconfig --comp-lzo

This creates an additional IP address. Test with a ping. Although TCP is not recommended, its still the easiest to setup.

Well, I guess it has to happen at some point. the home automation raspberry pi has died. Much to do with the stupid Strontium mini SD card. ...
