Mark,
It sounds like the PC you are trying to connect from does not have
an appropriate IP route to the dialed-in machine. Try one of the
following:
1) On the PC where you want to run the viewer, set the RAS server
as the default gateway in "Network Nbrhood->Properties->Protocols->
TCP/IP->Prope
My apologies for spamming the list with my previous reply to
Mark's message. Apparently all vnc-list messages come with
a "Reply-To" setting of "vnc-list", which I did not notice
at the time.
Why is this the case? Personally I expect my MUA's "Reply"
function to reply to the author and "Reply All

Oops. Better make sure that FP only gets allocated

Here's a patch for WinVNC. I've also made a WinVNC 3.3.3r
Hi Frank,
You need to point your browser at
http://hostname:58xx
where xx is the display number (almost certainly zero if
you are using WinVNC). The browser downloads the Java viewer
from that port using HTTP, then connects to the VNC server
at port 59xx and initiates the VNC session using RFB.
The patches for serving the Java viewer via the RFB port
are now available at
http://home.earthlink.net/~jknapka/vncpatch.html
The patched WinVNC is there as well.

Hi, Harmen,

Toward the bottom are patches for Xvnc and WinVNC
that attempt to implement HTTP tunnelling. They
just look for a POST request on the RFB port,
reply with an HTTP "OK", and then start the RFB
handshake. These patches should not interfe

Indeed, Xvnc allows loopback connections by default.

Is it a firewall or a proxy server? Those are two different
problems, one of which is solved more-or-less completely
and one of which is solved in a sort of half-fast way.
If the machine between you and your VNC server is a packet-filter
firewall that only allows connections to particular ports,

SSH (scp) is probably the best solution. However, you can use
FTP in PASSIVE mode, in which case it only will use one port.
I'm not sure if all clients support passive mode, though
(all servers should).

We've discussed VNC plugins here recently, and I seem to recall that
