UltraVNC file transfer issues.

[star521]

Hi, everyone!

When trying to use EchoVNC viewer to connect to another PC, which
is running UltraVNC Server(1.0.5.6), the progress bar appeared.
But after waiting 5 minutes, the progress bar still at 2%.
It seemed that the file transfer would never complete.

Then I installed UltraVNC viewer, it just worked fine!

Can UltraVNC work with other vncs, or its just a bug of EchoVNC(v2.35).
Any ideas?

thanks

I can't speak to EchoVNC, but I've found UltraVNC to be very picky about connecting to other VNCs, or even to itself. I've generally had better luck with TightVNC.

Theoretically, however, I think it's supposed to work.

echovnc not use ultravncviewer but tightvnc and in fact not compatible with ultravnc server.
UltraSam wrote is started before tight and real made their own file transfer as i remember from mind and made uncompatible.... vnc exactly opposite of the VNC multi OS cross plateform.

Hi, B & redge

Thank you for your quick reply.

Not familiar with tighvnc.
As UltraVNC and EchoVNC are open-source, I intend to custom one of them for my needs.

However, I'm surprised, the files containing in the two project's source code are almost the same.
UltraVNC can be opened and compiled(although have one or two errors) by using Visual Studio 2005.
But EchoVNC is not, the IDE threw out an error 'Project file is corrupted or damaged'. It cannot be rebuild.
What's going on ?
Do you familiar with EchoVNC ?
If anyone have the experience of compiling EchoVNC before, please give me some advise.


many thanks

EchoVNC isn't really open source at all. Its entire functionality is dependent on a "packet relay" that is closed source shareware. That's why I stopped looking at it long ago. ChunkVNC is much more an open source project, in that it incorporates an open source Repeater instead.

Of course the reason the bulk of the client and server are so similar is that all VNCs are derived from the original Olivetti/AT&T project.

I'm curious... What is it about EchoVNC that keeps you using it? Did you purchase their relay? (And how's it work compared to the UltraVNC repeater?)

Heyaz. Please note that you can configure both the EchoVNC Viewer and EchoVNC Server to handle just the "firewall-friendly" connection part, and then offload to a different VNC Viewer or VNC Server to handle the actual VNC session. Our app runs alongside other VNC apps just fine.

Sorry, I don't understand. (Also, I've gone off topic, since the OP really was asking about file transfer, which I gather just isn't compatible across VNCs.)

Are you suggesting using EchoVNC to establish a connection (presumably using your demo relay) and then essentially tunnelling something like Tight or Ultra through it? Or do you just mean that an Echo client can be used to talk to an Ultra server?

Hello, guys

I just download full source code of UltraVNC from the SVN on SourceForge.
It can be compiled using visual studio 2005.
Have to say the words: I love UltraVNC.

thanks

Yes to both.

Yes, you can use EchoVNC to establish a connection via an echoServer (which itself is a try-before-buy piece of shareware), and then use UltraVNC's Viewer and Server for the actual VNC session.

And yes, you can use the EchoVNC Viewer to connect to the UltraVNC server. Usually it works fine; the original poster here discovered an incompatibility in the file-transfer.
