VPN over TOR not working

[dYu784jseDsJ 5]

Hi there. VPN by itself works great. Thanks

TOR by itself works, both using the TBB and using 127.0.0.1:9050 (SOCKS5) in all other browsers/software. However, when I put that info into AirVPN, I get "fails to connect". I've seen some others post this problem, but without much debug info. But here's mine:

And from TOR's perspective, the connection attempt from AirVPN above adds this to its logs:

Oct 24 01:58:47.060 [warn] socks5: command 3 not recognized. Rejecting.

Oct 24 01:58:47.060 [warn] Fetching socks handshake failed. Closing.

Help?!

Hello!

Quite difficult to figure it out... anyway, can you please make sure that the proxy types match? OpenVPN supports connections over both http and socks proxies, but it must know in advance which proxy type it will meet. Perhaps OpenVPN is expecting a http proxy instead of a socks one.

Kind regards

[dYu784jseDsJ 5]

Yeah, selected SOCKS in AirVPN's settings.

[Staff 9751]

Hello!

Can you please try with OpenVPN or OpenVPN GUI directly? The generator for the files you need is available in menu "Member Area"->"Access Without Our Client".

After that, please send us again the OpenVPN logs and your configuration file.

Kind regards

Ive been having this same exact problem with the same error codes. Interesting.

[dYu784jseDsJ 5]

I spent an hour fooling around yet couldn't get OpenVPN working directly. Can't test it over TOR until I figure out how to get it working directly. I think I was successful the last time I tried it, but this time it says connected, yet my connection remains direct. :dry:

I'm having the exact same problem.

I'm running Vidalia Tor bundle, configured AirVpn to use SOCKS on 127.0.0.1 on 9050

I'm wondering if Openvpn uses a different version of the SOCKS protocol when communicating with Tor.

As I have this message in the Tor logs:

[sat 15. Dec 12:33:41 2012] Unknown SOCKS Protocol - One of your applications tried to establish a connection through Tor using a protocol that Tor does not understand. Please ensure you configure your applications to use only SOCKS4a or SOCKS5 with remote hostname resolution.

I'll try and investigate further to see what version it uses by default - and get back to you if it is any different.

It's taken me a while, but I think I have it working, but could someone's advice to make sure.

I had set up Comodo firewall following the guide on the forum, so that if the OpenVPN dies then all apps are blocked.

However to get OpenVPN talking to TOR I had to allow access to port 443

otherwise I got the errors stated before.

I've tried OpenVPN using the Openvpn gui on with configs for ports 53 and another for 443, and had TOR setup to allow 53 within it's allowed ports.

But this too was only able to connect on 443.

On the face of it the end point IP in TOR is the start point for the VPN, so it seems to be doing the right thing.

However, what risks to me in terms of P2P by exposing port 443?

I've a feeling there is a better way of doing this.

Tor cannot forward UDP packets, only TCP. Check the mode tab to ensure TCP protocol is selected.
