It is an absolute fact that VNC Server does *not* attempt to connect to a
DNS server except in the case that it has been requested to make an outgoing
connection to a listening viewer.
Either the program you are using to detect these accesses is wrongly
attributing them, or some aspect of
Steve & Joel,
The VNC Server's process is *not* called vncserver on Unix! It's called
Xvnc. vncserver is just the front-end used to launch the Xvnc process.

Assuming the routing capabilities of the first server allow you to forward
ports, all you need to do is forward port 5901 from the 1st server to the
second server.
Case 1: Port 5901 forwarded to 2nd server port 5901

Hi,
I have two servers that I want to control remotely. The first one has
the direct connection to the Internet and the second one connects
through the first one using NAT. This means that only one server has a
public IP, the other has an internal IP.
Can I use VNC to connect to both servers?

I probably have the name wrong. (I usually use Linux.) It might have
been winvnc, or something. It was, without doubt, the vnc server
under Windows.

The next version of VNCScan due out within a week will have this exact

It has a tab that shows you the date, time, logged in user, and duration

Correct me if I am wrong. I am assuming first an encrypted session is setup

authentication. Once all the authentications are performed, it results in
secured data across the link.

The public/private key exchange *is* the server authentication stage, and is
used as the bootstrap for the secure encrypted session.
Please refer to my previous replies to your mailing list messages regarding

KDE also has this problem. You might try KDE for your VNC user session

I just installed internet-monitoring s/w on a Windows computer as part
of ridding it of a virus, and I saw the the service-level vnc server
was accessing a DNS port, even when no one was supposed to be
