Re: VNC client/server combo doing VNC over HTTP

2 short infos to clarify :

1. VNC over http doesn´t exist

Is that strictly true? Both Ultra@VNC and RealVNC Personal Edition offer a version that allows access through a web browser on the client side, specifically to be more firewall-friendly; what are they doing if they are not putting VNC over HTTP(S)?

2. Port-Numbers can be altered with any version

I do know that much, but that's only half the problem; the protocols allowed by the corporate firewall are the other half...

Solution would be : ssh on Port 443 ... with that you can trick most proxies with the "connect" method to use any proxy-capable ssh-client (putty for example) -> after ssh-connection is ok .. you can do vnc-over-ssh (simple Port-forwarding)

more professional :
use SSL-VPN-software like ssl-explorer( http://3sp.com/showSslExplorer.do?referrer=sslexplorer), which can do port-forwarding in y very simple manner

Thanks for the suggestion, I'll try it right away, but I don't expect it to work as I expect I'll find the firewall is not configured to allow SSH going out of the network to the internet any more than it would allow incoming SSH (we are talking about a multinational corporation here...)

Unless I am being inordinately stupid, in which case please have patience with me and correct me, hard-core firewalls are filtering based not only on port number but also on protocol. I am not sufficiently senior in my organisation, nor is what I'm trying to do sufficiently strategically important, to give me the power to influence my company's internet facing firewall policy; so the only option left is to find a way to tunnel this traffic over an existing open port/protocol combo. The most reliably available is HTTP(S) over the usual HTTP(S) ports eg 80, 81, 443, etc...

    I'm looking for a VNC server to run on my home Debian setup that will
    allow me to connect to it from work. Trouble is, work is behind a
    (justly) paranoid corporate firewall which will allow me to
    connect out
    on HTTP/HTTPS on the usual web ports and not a lot else. So I'm
    for a solution where the server can be Debian, the client can be
    2000 and comms between the two can be HTTP or better HTTPS over
    80/81/443/8080 etc.

    I stumbled over x11vnc which looks good but doesn't appear to support
    communicating over HTTP(s). And my searches on sourceforge etc find me
    products that do what I want but the server side has to be Windows.
    Anyone got any alternative ideas?
