RFB ERROR: SSL JavaViewer <-> Distributor5.exe <-&g

Post by Zagrophyte »

I have tried using the SSL Javaviewer to connect to SC.exe via the SSL repeater without luck, I get this error:

Error: Unknown RFB rectangle encoding 16

It changes my desktop BG, and connects, but then fails immediately on this.

If I use UltraVNC Server (1.0.1) to reverse-connect (Both to uvnc.com and my own repeater) it works. Also if I use the VncViewer_SSL.exe to connect, it works.

I've tried this with the UVNC.com SSL Java Viewer, and also my own copy. Something about SCIII.exe does not like the Java Viewer, or vice versa. Here is the debug output for both server and client (why can't I select text or output the debug info?) :P

Server (SCIII.exe):

Client (SSL JavaViewer):

I have tried other encodings via the ENCODING parameter (e.g. ZRLE, Hextile) to no avail.

Rudi, redge; any ideas?

Ah, thank you.

Are there any workarounds such as using a different encoding? My friend and I are working on a GUI standalone Java front-end based on the JavaViewer SSL code:

http://www.juxentente.com/~zenzagg/dist.rar

It allows you to specify all parameters, even User/Pass. It also still accepts command-line entries. Let me know if you think this would be useful in the future.

With the VncViewer.zip you would use:

java -classpath VncViewer.jar VncViewer HOST ID:12345 PORT 0 REPEATERHOST uvnc.com REPEATERPORT 443 USESSL 1 TRUSTALL 1 ENCODING zlib

Since the last reply to this topic is quite a while ago I would like to ask if there has been any change to the Repeater to properly support SSL Javaviewer without the above described problems.

In our situation it would be very helpfull to let the supporting person use Java Viewer instead of VNCViewer_ssl but stil using port 443 and encryption.

At the end of the day we would like to e-mail an URL(with all required parameters) to the supporting person. All he/she has to do is then click on the link to get connected to Repeater and the SCIII waiting with same ID.
Optional the ID can be provided manually by the supporting person.

Was this issue ever corrected?

I found that using hextile for encoding would allow it to work, but unfortunately hextile does not provide suitable compression for use over the internet. When tight or zlib is used, the same error is returned.

Poking around the native server code of old revisions, I've found that pointer position updates seem to be the root of this problem. They were introduced in version 1.5 (I think) and the JavaViewer wasn't updated to account for that. I'm working on fixing that, I'll post my findings if anyone is curious.

Absolutely, please do. The JavaViewer code seems to have been lagging for some time. I think someone else tried to hack in repeater support a while ago.
