Yes, I "get" that, but then I would ask if authentication is transparent to the repeater - which would be fine - then why do I not get the password challenge from the server?

You mentioned this is "because" the server side is using a proxy? It seems bizarre that would be a good reason to drop security. But if true, direct me to more info on that or is there a thread on it?

I'll check out the other two things you mentioned. I want to have a repeater, but I need to do something to prevent anybody who figures out (or hears) the port numbers from using it!

As always, great work, thanks for your input!

Because the UltraVNC server is making a reverse connection to the repeater. If you need authentication you must use a plugin such as SecureVNC.

Bizarre indeed. Authentication when the server is making a reverse connection has been requested before, I don't know what other threads to show you. Remember that basic VNC authentication sucks, it's probably not worth the developers time to add this functionality since authentication does work with reverse connections when using a DSM plugin (which you should be using anyways).

I get security by hosting the repeater on my local LAN and only port forwarding the server port. Since a viewer cannot connect to the repeater from outside the network it makes for very good security. If you need a viewer connect from the outside and still keep high security just setup a VPN.

Well, it occurs to me that very few programmers would pass for "normal" in most social circles - and I'm no exception. :D

I'm getting a strong vibe that the DSM plugin is what I want. I'm going to do some testing with that on the PERL repeater.

Should I update the PERL script to the latest first? (I'm running the one that is with ChunkVNC 3.2)

The one included in 3.2 will work just fine but Rat's modified repeater does have some neat added features for those using a shared hosting account to run their repeater.

Yeah, I actually didn't know SSVNC had repeater support!!! =) =) But I am using SecureVNC plugin, so that probably isn't an option. /me wonders what it would take to integrate that into Vinagre ("Remote Desktop Viewer" in Linux) as well as repeater ID support... </wishful thinking>

Speak for yourself I'm completely normal! :)

I routinely run my ChunkVNC Fork with a DSM plugin, (its all built-in), through the Perl Repeater... works fine. As far as I know the official ChunkVNC release works the same way.

I don't get it. I read the linked post, too. Please elaborate? Are you sure you don't mean "Don't use X11vnc" ?

I found a problem that seems to have something to do with the repeater:

You could try my ChunkVNC Fork. I've never experienced any problems using it with the Perl Repeater.

I guess I get the honor of making the first complaint then. I tested your Fork version 3.1m and found it had the same problem. And another problem with the Viewer exiting. Also is it normal for Windows to ask the EXE security question at least twice running the fork viewer?

Thank you, Rat, for your script and installation instructions.
I've set it up on Ubuntu 11 and it is running fine.

I don't think there's any functional limit, practically though it depends on available bandwidth etc.
