I have run vncserver without passwords by just commenting out the parts of
the vncserver script that refer to passwords.  It runs without errors, and
users simply connect through a shortcut to their batch file on a server (the
DOS batch file just runs the vncviewer command and connects them to their
individual session, then exits the command window).  Of course, this is on a
closed network where users are sharing machines anyway, so security in this
application was not needed.

I know this doesn't get down to your core question of how to make the RFB
protocol work the way you want it outside the vncserver script (I'm assuming
that's what you're talking about), but it does indeed work on Linux.

Subject: Using VNC without authentication


Hello!

When I look at the RFB-protocol it seems to be possible to run VNC without 
authentication, i. e. without having to provide a password. Is this possible
with 
Linux, too? (Security doesn't matter at all!)
Alternative question: the RFB-protocol says something about DES encryption 
of the challenge sent by the server using the password. How is this DES 
encryption exactly done and where can I find e. g. a C function which does 
this for me in a simple way, like:
answer_to_send = vnc_des_function (challenge_sent_by_server, 
my_passwrd);

Regards,
Hans
