HTTP proxy/firewall

Post by Imago »

I need to connect through a HTTP proxy/filewall.

To do that VNC packets should be encapsulated into HTTP protocol.

Is that possible? Do I need to use something like httport? Why do not implement "http encapsulation" in VNC itself as an option?

use zebedee

You can connect via a firewall setting up zebedee (a tunnelling and encryption freeware program).

Protocoll Option...

Post by louk »

Zebedee can be used, I have done that last week. How to use it is described here:
http://www.winton.org.uk/zebedee/manual.html

But if only port 80 for http traffic is open and the firewall does a check of the protocoll on application level, zebedee does not work on port 80 as it is the case in our companys firewall.
So I choosed port 443 which is the standad port for https (SSL) connections.
For tunneling port 80 I used httport/htthost which can be found here http://www.htthost.com/ . It allows also to pass a proxy but it is quite slow.

It would be very nice, if UltraVNC would offer an protocoll option for the traffic. A tunnel software would not be required any more and in a lot of cases it would ease the use tremendously.

Stunnel/ssh/OpenVPN

Post by Leonard »

I would suggest checking out stunnel.org. It uses openssl (openssl.org).

If you are more adventurous, want more functionality or simply need to authenticate with the proxy (theses can get really involved):

- OPenVPN (http://openvpn.sourceforge.net)

- You couls also use ssh
-- ssh for windows (http://sshwindows.sourceforge.net/)
-- ssh as part of cygwin (http://www.cygwin.com/)
-- putty (client only) (http://www.chiark.greenend.org.uk/~sgtatham/putty/)
