Bug report "couldn't write GET header"

[Kevin Levillain]

Hello,

I'm having trouble with httptunnel and I hope you might help me because I haven't find anything conclusive on the Internet.

I'll try to be as precise as possible, but I'm quite new to these things so please feel free to ask for more information if needed !

I have installed httptunnel on my ubuntu server 12.04.2 LTS yesterday 

sudo apt-get install httptunnel

and launched hts with

sudo hts -F localhost:22 80

Then I have installed httptunnel on my Mac OS X 10.8.2 today thanks to httptunnel-3.0.5.tar.gz that I found on your website. (I had to install Xcode with the command line options to do that with your script configure. I must say it has not copied hts and htc in my /usr/local/bin folder, I have done that myself).

Then I launched htc on my client side (just testing before serious things begin, without proxy as I am able to connect to my ubuntu server with openssh directly, without httptunnel)

sudo htc -F 2222 SERVER.IP.ADDRESS:80

Then I try to connect with ssh on my mac :

ssh -l username -p 2222 localhost

and after a while I get the error ssh_exchange_identification connection closed by remote host

Knowing that the first step to debug is to know where the connection failed I looked in my logs and pasted it below.

As you will see, the connection itself doesn't seem to be the problem : I get the connection on the server side but I get the error "tunnel_accept: couldn't write GET header: Invalid argument".

I would be very grateful if you could help me (or tell me where to get help !)

Thank you very much,

Kevin Levillain
