Sorry for this newbie question:
Why do I need two ports 5800 + 5900 for TightVNC/UltraVNC?

Ok, the docs talk about 5900 for the VNC viewer and 5800 for Http client.

But what does that mean? When do the VNC server use the first and when the second port?

From my understanding the VNC server needs only ONE port (e.g. 5800) where it listens
for incoming requests. That's it.

Port 5800 can be used by a Web client (like Internet Explorer), port 5900 is
used by the VNC client.

I found out something the other day that I didn't know about VNC. When using
the web interface it uses both ports. The build in "web site" runs on 5800,
but once the Java Applet loads in the browser and engages it uses 5900 just
like the regular VNC Client does. So I guess, when you use the web
interface you actually use both ports.
