/><br /><br />><br />><br />><br />><br />> Hi everybody!<br
/>><br />> I'm looking for your help, I need to make a reverse connection
with <br />> FreeNX, like the reverse connection of VNC that the server
connects <br />> to the client and the connection is succeful, no router or
firewall <br />> configurations, can it be made? how?<br />></p><p>I
won't say that it's impossible (nothing is impossible in the Open Source world
:p), but I can't see any easy way of accomplishing this. </p><p>VNC uses
(AFAIK) a rather simple authentication mechanism, but the NX technology
uses SSH (with pub/priv key) + user&password. "Reversing" this
mechanism doesn't look (to me) to be a simple task. You would also need to make
a custom client (look at the FreeNX Client QtNX for GPL'ed code) that would
accept the connection from the server.</p><p>Maybe I'm looking all wrong at
this; a simple program (on the server) could send a special command to a custom
client with info about the server/IP that it (the custom client) should initiate
a connection to. That might be a more probable workaround to it...</p><p>My 2
cents :-)</p><p>Regards,</p><p>Terje</p>
