I had not known the SFX could be able to start the embedded .exe with " runas admin".

Thanks for the information.

That's the difference of the two SC generator, as mentioned on the website.

But I upload the same custom.zip to the generators, the returned .EXE differ only on the MSRC4Plugin.dsm embedded.
The first generator provides the MSRC4Plugin.dsm ...

If the key "AuthRequired" doesn't exist, you can creat it manually.

It is a DWORD, and give it a value of 0, will result the UVNC server accept No Password configuration.


UltraVNC abandoned the use of registry for holding its setting since ver.1.0.4.
See this post for a detail technical ...

I need to use UltraVNC without a password, i followed your instructions and i dont find the ultravnc.ini, I even performed a windows search and nothing..

I am using UltraVNC 1.0.2

You are using 1.0.2, which is a very old version of UltraVNC.

This version follow the original VNC design, which ...

Check if this trick is still working...

I guess it has to do with unicode and multi char.
If plugin and viewer use a different keyset, the internal representation of chars like ë é ç is different.

Then it is a wrong passphase issue, and the returned status s/b "Authentication Rejected"

How come it can result with the messege:

server ...

Yes, both UltraVNC server and viewer are interpreting the port number in this way.

This may be has its purpose: to make it able run as the old VNC that using a parameter called Display Number (a 2-digit number). I'm not sure the exact meaning this parameter, but its syntax is the same as specifying ...

There are two versions of PcHelpWare. The function of them are the same, but they differs in GUI.

1. The PCHelpware Release 1.0
The server of this version like this:

and only ONE connection definition is allowed



2. PCHelpware server (GUI SC ...

- You had specified to use dsmplugin in the helpdesk.txt;
- the dsmplugin does exist inside the SC package;
- the connection can be established, but the viewer complaining the server is not using any dsmplugin.


Sorry I can explain why this happened

I got the following error(s):
http://s14.postimage.org/azy47xo0x/Capture2.png
You got this error, that means the connection was successfully established at the repeater, only the viewer found that the server was not using encryption.

However, based on your verification: the [HOST] statement ...

Investigate your original generated SC first:

Have you used 7-Zip to open it, and checked if the SecureVNCPlugin.dsm (renamed as msrc4plugin.dsm) existed ?

Here is what my helpdesk.txt looks like:

[HOST]
Test 1
-plugin -id 1239 -connect repeaterIP:5500 -noregistry
This should be OK


My viewer setup is as follows:
http://s17.postimage.org/8crjnlffz/Capture.png
Although the image is too small and difficult to recognize, but looks like you had ...

I have also tried using the SecureVNCPlugin.dsm as stated on the following page:
http://forum.ultravnc.info/viewtopic.php?t=27633&start=5

When using MSRC4Plugin or SecureVNCPlugin, the viewer gets a message box that says: "You have specified an encryption plugin, however this connection is ...

Running the "server" and "viewer" on the same PC should not cause any problem.
I use this method to test my SC.exe frequently.

The SC, since it was born, was designed to use a non standard RFB protocol, the UltraVNC viewer was coded to handle it. But this happened long long time ago, and the x64 ...

Got this error:

Connection Failed - Error reading Protocol Version
that means the SC.exe and the viewer were able to contact, just something went wrong.


In your 1st post, you had mentioned using Ultr@VNC Viewer x64 1.0.9.6.2 in your test, I assume you were using this viewer as well in the local ...

There are several points you need to change/correct:


1. Inside the helpdesk.txt of your created .EXE file

[HOST]
HELP DESK - Dennis, double click HERE
-connect {FRIEND}.hopto.org:5500 -noregistry

The syntax of the statement is correct, but this had NOT configured using encryption.



2. The ...

The default setting of UltraVNC Viewer is saved at a file named "Options.vnc"

This file is located at:
\\Documents and Settings\User_Name\Application Data\UltraVNC
(or = “%appdata%\ultravnc")

So with proper setting inside this file, the viewer will start with your preferred configuration. In your ...

This characteristic has been implemented since 1.0.9.6

The "accept/reject window" is now always displayed on the top.

Sorry, but still the two links just returning the picture of the frog.

I'm not able to watch your posted photos.

What appears on my screen is:

The .vnc file is able to save the native VNC password only.

If you are using the Pass Phrase feature of SecureVNC, it will not be saved inside the .vnc file

Open the ultravnc.ini, check the setting

AllowProperties=

If its value is "0", an authentication-diabled server will bring up the said popup.

In this case, change this setting to "1" will solve the problem.

This bug was found on 1.0.8.0 & 1.0.8.2, and should be have been fixed in the releases after.

See these threads:
VNCviewer Bug - crash when "Server Screen Scale by" not 1/1

ServerScale in 1.0.8.2


You are using 1.0.9.6.1 stable (I suppose you meant viewer), but how about the server?

In fact ...

The "-sc_prompt", by its original purpose, is to trigger a prompt window at the listening viewer, if the server is making a reverse connection to that viewer.

So in my example, it is in fact doing nothing, since the connection is making to a repeater.

The "-multi" is the element to meet your ...

Try running the application session in this way:

This can be achieved by using a Batch Script with some 3rd party utilities.

I submit herewith a sample.
You need to download two free tools:
- vncpwd -- tool to encrypt the VNC password.
- inifile -- tool to write the encrypted vnc password into the file "ultravnc.ini"

Here is the structure of the ...

1. - I deleted all keys on both sides and was able to connect with the password plus 'use DSMPlugin' being marked .
I suppose this connection is NOT encrypted, is it ?
Even though unmarking 'use DSMPlugin' at the viewer-side didn't give me a connection anymore ? Then the server is configured to ...

I want to generate one xxx_Server_ClientAuth.pubkey and deploy that to many maschines.

Now generating one xxx_Server_ClientAuth.pubkey on one maschine and using the xxx_Viewer_ClientAuth.pkey on a remote client works, but only on the maschine the key was generated on.
When I do a fresh install of ...

This will happen on UVNC 1.0.9.x ... I suppose you are using one of these version.

It is because these version implement a feature ... auto re-bind the IP if there is a change, so establishing a PPPoE will triggger this operation. Unfortunately this requires a restart of the uvnc service, thus all ...

I guess your connection was done with SecureVNC plugin.
Nope, again I'm just using stock UVNC 1.0.9.6.1. ........
