UltraVNC

Oh man, this has got to be something simple. I'm sure someone has run into this situation, before. I surely can't be the first person to encounter this. I have already done an sfc scan and a Windows refresh. That should only leave a video driver and it's the latest from Lenovo.

I'm really stuck ...

I assure you I am trying to connect from a laptop to a lan server. Two totally different ip addresses.

I am embarrassed to tell you that three computers are involved. I just assumed that everyone these days did it the way I do. On my remote lan server (linux), I have one port open to the outside ...

I am running a fully up to date ultravnc server on windows 10 (also fully up to date) version 1.4.3.6 . I have all kinds of machines connecting to this server. I have Windows 11 machines, and various linux machines. All work just fine: except one Windows 11 Lenovo IdeaPad machine.

On that Win 11 ...

I have not been satisfied with the cursor when I connect to an Ubuntu 12.04 LTS system that I have. I usually get just a 'dot' for a cursor. I am running Win 7 (32 bit) on the viewer system, so I setup a shortcut on my desktop like so:

"C:\Program Files\uvnc bvba\UltraVNC\vncviewer.exe" -connect ...

I am running uvnc 1.1.9.0 ( but this happens on previous versions as well) on a win7 & win 8 client machines. When I login to my Ubuntu 12.04 LTS desktop, all I get is a 'dot' for a cursor. All the windows uvnc servers display an 'arrow' when connected. I've noticed this for some number of releases ...

Rudi,
I am following up on my latest observations. I have discovered that the new vnchook.dll is, in fact, the culprit for Windows XP. The following is the info on the vnchook.dll installed with 1180:

Description: VNC hook for Win32
Size: 53.7KB

The info on vnchook.dll for 10962 is:

Description ...

Rudi,
I have done a clean install of ver 1.0.9.6.2 on my XP machine. I downloaded the ver 1.1.8.0 bin zip file and extracted JUST the winvnc.exe file (no other files were extracted). I replaced the ver1.0.9.6.2 winvnc with the ver1.1.8.0 version and then rebooted. I have retained my oringinal fast ...

Thanks for your help, Rudi. You are so right! Identifying the problem is always the hardest part.

I am still functional with ver 1.0.9.6.2, so as I get time I will try other things and let you know what I discover. My xp machine is so bare bones (only use as file server) that I can't see anything ...

Rudi,
I have run more tests and the results are the same: extremly slow. When I say 'extremely slow' I mean that I can watch windows draw each patch of the windows as if they are in slow motion: borders, scroll bars, title bar, etc. I am always rebooting after the changes.

I have made sure that ALL ...

Thanks, Rudi. I'll do another clean install and then check the polling options then reboot.

I'll report back...

My poll options are:

Poll Full Screen - (checked)
Poll Forground Window - (checked)
Poll Window Under Cursor - (checked)

System HookDll - (checked)
Low Accuracy (Turbo Speed) - (checked)

All others unchecked.

Rudi,
Sorry for not getting back quicker. I had a lot of tests to run.

I tried your suggestion of renaming old uvnc and extracting new (v. 1.1.8.0 from bin zip) in it's place. I then rebooted and everything was fast!. I then uninstalled uvnc from the xp machine and installed ver 1.1.8.0 again. I ...

Hi all. I have been using uvnc for so long I can't remember when I started (~2005?). Any way, I have a uVNC server running on an xp machine that I use for a file server (single processor, 1gig ram). My development machines all use Win 7. Also, I have a laptop running Win 7 and a Linux machine that I ...

I, too, am getting the Microsoft Security Essentals message saying that 1.0.9.6.2 is a threat.

I just installed uvnc 1.0.9.6 (32bit) on an XP server at home. I connect locally to this server from a Win7 (32bit) desktop and a win7 (32bit) laptop. Both exhibit strange mouse pointer movement after connection.

If I move the mouse rapidly to a position on the screen and stop, the mouse pointer ...

I have been experiencing the same issues described above. Today's fix (reupload) fixed the problem for me.

Thanks, Rudi...

3. Consider this situation:
winvnc + secureplugin (key not exist)
vncviewer + secureplugin + *_ClientAuth.pkey

reversed connection still OK

In this case, the server's secureplugin is a patched version from a hacker, which always provide an special key (selected by the hacker) to the listening ...

@YY,
I tried your test with a browser already running on the server and you are right, the Website button works under those circumstances. As you indicate, it appears to be a coding error. Nice catch!

Dick

@redge,
After further testing I have found that on the viewer I can press the SecureVNCPlubin's Website button and it does open up Adam's web site.

However, I get nothing when I press the Website button on the server running as an installed service on XP.

Dick

YY,
You are correct. After I copied the *.pkey to my viewer machine, I DID NOT restart the server. When I restarted the server, all worked well.

As to the second issue, what I meant was: why have the "Generate Client Authentication" button available on both the server and the viewer? Convenience ...

@YY:
I, too, have read Adam's site and have read that passage many times. It really doesn't say how to use the 'Client Generation' button. I tried it anyway and it generated two keys: a *.pkey and a *.pubkey. What are we supposed to do with those keys? I tried copying the *.pkey to the viewers ...

YY,
Thank you for your clear explanation. Where were you able to find this information? Or did you just figure it out for yourself? I have looked everywhere.

Could you also explain how to use the advanced options of using the Client & Server Generation buttons?

Also, what does the Website button ...

Sandman,
I can get the plugin to work in the default mode; that is, enable the plugin and set a uvnc password. At least the info popup says encryption is working.

However, I've tried numerous things with the Generate Keys buttons and nothing seems to work. I've read Adam's site several times and ...

I recently installed 1.0.9.5 on my systems. I enabled the SecureVNC Plugin. In this default condition it works just fine. However, I want to try the Passphrase option to increase the length of the 'password' (i,e, more than 8 chars). Here's where I start to have problems.

Do I need to set the ...

Thanks, Rudi,

I guess it's time to experiment.

Dick

Rudi,

Excellent explanation.

If I have SCHook.dll and VNCHook.dll present, how do I tell uvnc which to use?

Or do I just have one or the other present when running and uvnc automatically picks up the dll?

Dick

Redge and/or Rudi,

I am very confused about the video drivers for uvnc. In your most recent posts (and Rudi's post), you mention SCHook.dll, VNCHook.dll hook.dll and mirror driver.

What are each of these?

When should I consider using one or all of these?

I see in the options list there is an ...
