I’ve got the server and client running in debug mode and the last line in the client reads:

http_write_request: GET /index.html?crap=1313771171 HTTP/1.1

On the server side the last line reads:

connection from 123.456.789.100:12101

…and just sits there doing nothing. Any idea what is happening?

I’ve tried using Telnet to emulate the client and I get a full response when I manually type in an HTTP GET request.

HTTPtunnel itself does NOT encrypt your network traffic — so the answer is NO. But if you use HTTPtunnel with SSH the answer is YES.

I personal use super network tunnel, can find it at http://www.networktunnel.net, it’s more easy.

How can I lunch my home server behind restricted firewall and router to Internet use by your HTTP tunnel without touch router and firewall.

hey adam, there is no vs project file as this is a cygwin port. I guess you have some ntlm issues, you need to authenticate yourself on the isa proxy…

Having similar problems trying to connect through an ISA proxy… any chance you could post a link to your Visual Studio project files & Windows source to allow us to debug more fully?

I’m trying to get through my company firewall. Until recently I could just use PuTTY to set-up a connection to my home sshd and everything was fine. But now the proxy’s configuration has been changed. It seems that the proxy blocks the http_connect command. And it also uses NTLM authentication.

So, I’ve installed CygWin on my WinXP work PC. In CygWin I’ve installed NTLMAPS, which creates a ‘normal’ HTTP proxy. NTLMAPS connects to the company proxy. This sort of transforms the NTLM proxy into a regular one. My plan was to use HTTPTunnel to connect to my home server (running hts) through the NTLMAPS proxy. This way, I can still use HTTPTunnel (which doesn’t understand NTLM) to bypass the http_connect restriction.

The NTLMAPS proxy works, I can have my Firefox connect through it and receive pages (although it’s slower of course than directly through the company proxy).

But, like Lorenzo, when I try to have ssh use the hts-htc tunnel, the htc client dies with any error message. Seeing the htc is connected to NTLMAPS, it shouldn’t see the NTLM authentication at all, so I doubt Lorenzo’s conclusion is correct, I fear that there is a different problem.

Does anyone have an idea?

Just find how to tunneling without HTTP proxy :) Have fun! Thanks to Dave!!

You could try to use a NTLM proxy: http://apserver.sourceforge.net/ (old website: http://www.geocities.com/rozmanov/ntlm/). Good luck!

It seems I had just overlooked the fact that HTTPTunnel does not support NTLM authentication.. and this caused all of the problems.
A shame, since most firewalls are ISA and they do require NTLM auth.. any chance of having it implemented?
Thanks again!
Lo.

Thanks for the new build! I’ll try it immediately and I’ll let you know as soon as possibile.
Again: thanks!

I will release a debug build of htc, this should help to trace some issues

Hi
I’m sure I’m not missing any file because the HTTPTunnel does actually work, as long as I don’t use it for ‘complex’ traffic like SSH or OpenVPN.
The process remains alive until I open Putty and connect to the localhost:forwardedport or openvpn (same), at wich point HTC simply disappears from the process list (and the tunnel closes of course..)
Thanks!

You could use filemon from sysinternals to check if you miss some files…

I fixed the issue (installed on fresh machine) but…
whenever I use SSH or openvpn (in tcp of course) HTC process dies.. any hint?
(using the same cygwin1.dll that came with it)

you could use openssh and httptunnel in different directories, windows allways looks in the current directory for the dll.

Don’t know why, but it seems the version of cygwin that comes with the latest openssh does not work along with the one who comes with httptunnel.
At beginning, i used httptunnel alone and it seemed to work. After that, I tried installing OpenSSH, and then httptunnel began complaining about it having an older version of cygwin1.dll.
Following the on-screen suggestions, I’ve updated to the latest cygwin from cygwin.com and updated all the .dll to the latest rev..
Now .. there’s no way to make httptunnel to work: when I launch HTS, it just hangs.
removing-Reinstalling cygwin does not solve the issue.
Please, give me some advice, thanks!
