I have been trying to generate a config myself, without success.

Would it be possible to get the source code of the sc generator so that i can do it offline? if you have some sort of offline binary that would be cool too :)

Best regards,

JC

The generator just make a 7zip sfx file.
You need 7zip
http://www.7-zip.org/

1) download
http://www.uvnc.com/custom.zip
2) http://support1.uvnc.com/cgi-bin/upload9.pl
select the zip, user foo passwd foobar
3) download custom.exe

You now can open the exe ( this is actual a 7zip sfx) with 7zip and extract to a folder.

You now can make all changes to the helpdesk.txt and test it by running winvnc.exe
When all settings are ok, open 7zip, add all files select create sfx

There exist also a 7zip sfx maker project, they just added some GUI to create the sfx
http://sourceforge.net/projects/sfx-maker/

The icon insite the exe is changed with a resource tool
http://www.angusj.com/resourcehacker/

Code: Select all
7z a -mx=9 -t7z UltraVncSC.7z winvnc.exe rc4.key MSRC4Plugin.dsm helpdesk.txt icon1.ico icon2.ico logo.bmp background.bmp enter.bmp
copy /b UltraVnc.sfx + config.txt + UltraVncSC.7z UltraVncSC.exe

UltraVncSC.7z=7zip sfx extractor (default name=7z.sfx)
config.txt
Code: Select all
;!@Install@!UTF-8!
Title="UltraVnc"
RunProgram="winvnc.exe"
;!@InstallEnd@!

Thank you Rudi.

I have been playing around with 7zip sfx and winvnc(SCII) that is available as a separate download as a workaround for the failure in gettin a propperly generated SC from the perl script.

I found a curious detail: winvnc behaves differently with the presence of the dlls and only presents the SC gui if they are present falling back to simple standard vnc server when they are not.

I did not realise that the user and password that you need to use on that web interface http://support1.uvnc.com/cgi-bin/upload9.pl was actually the one that you provided as i was trying to get it working with another credentials because i thought that it was some kind of credential that was going to be bundled with SC. As it turns out it's just some security measure you implemented on the perl script usage.

Anyway, that mistake made me dive into some basic of understanding on how SC works by trying out some things and going through the forum :)

The sc online generator is not working. I selected the zip file to upload but the page does not issue the download links. Thanks.

Any idea about when the binaries on the page will be replaced with newer versions? Most Windows 10 PCs are having a hard time getting anything through...

First of all, thank you very much for your tools.

And second... Are online creator tools working? I mean, I've tested the "Experimental June 2015 win8 win10", and it seemed to work... Until yesterday.

I've even tried to upload a zip that was just the "vanilla custom" file (no folder in the middle, ofc) and still no luck. Also the plain "helpdesk.txt" alone zipped and also fails.

SecureVNC-Plugin with creator tool?

Postby Chaka » 2018-07-11 19:54

Just tested last sc online creator method "May 2018 win10" here. It worked but only with unsecure msrc4plugin. Contained files in my zip-file like ClientAuth.pubkey and SecureVNCPlugin will be ignored. Is it possible to use the more secure plugin with online creator?

Second question: Whats the benefit using online creator then local creation? Local created executable are not signed, so most security suites have problems with my file. Therefore online creator would be the better way. Am I right?

Indeed, the online creator sign the file.

Because we sign it, you can not upload exe, dsm or dll
You can only add the config, icon, bmp.

msrc4plugin is also secure, it only use a smaller key.

msrc4plugin make use of the buildin MS encryption -> no export restrictions
SecureVNCPlugin use openssl -> could be restricted

Hi, I tried "May 2018 win10" online creator but it runs without admin rights on start, also it show max 11 connection before scrollbar is visable.

In "June 2015 win8 win10" it runs with admin rights and show max 13 connection before scrollbar is visable.

Could you please make additional version, with admin rights prompts + 13 connection on list before scrollbar show?

Added the admin right start, that's something on the website that needed to be set.

The max number is something in the code. I will change it next time i make a sc update.

How about releasing manual tools to build on one's own server / PC? The last update is 3 years old :(

I created SC for Win10.
Starting SC and doubleclicking a host sometimes generates a Showmessage containing the commandline parameters. Instead I would have expected the reason of the error, so a user is now left clueless of what happened.
It can easily provoked by connecting SC to a host (host is shut down for this test) and quickly start a 2nd instance doing the same.

Today a client had just one instance running and got the commandline display also. We had no idea what the actual error was, and gave up, and had to use teamviewer.
Can this please be examined and fixed?

Another similar problem: SC immediately closes when the PC firewall blocks outgoing traffic. It would great to see an error message before closure.

I've been trying to make VNC SC to use the new Encryption plugin with the newest VNCViewer in Listen mode, but no matter what I try it does not work...
In the download section you say that support for SecureVNCPlugin.dsm has been added, but it is not clear how to set up the listening side...
VNCViewer 1.2.3-1.3.2 in listening mode with either SecureVNCPlugin.dsm or SecureVNCPlugin64.dsm can't establish connection with VNC SC...
Special VNC SC Viewers on the SC download page don't support newer SecureVNCPlugin, and the newest VNCViewers (1.2.3-1.3.2) don't support the older MSRC4Plugin for SC...
The only working combination seems to be the old SC Viewer for SC (1.1.9.5 at the top of SC download page) with MSRC4Plugin, and SC client built with May 2018 win10 SC builder...

I don't understand what the purpose of the Listen mode is in the newest VNCViewer if none of the VNC SC can connect to it...

Retested:
Sc is working with 1.3.2 and SecureVNCPlugin.dsm

1) viewer 64 bit + 64bit plugin SecureVNCPlugin64.dsm
2)helpdesk.txt, entry with and without encryption
[HOST]
Internet support
-connect localhost:5500 -noregistry

[HOST]
Internet support encryption
-secureplugin -connect localhost:5500 -noregistry

https://www.uvnc.com/downloads/single-c ... loads.html
Last creator, buttom

win10 Same as pevious, but exe request UAC on start
-Added support for the SecureVNCPlugin
Howto
*Add SC_Server_ClientAuth.pubkey to zip
helpdesk.txt
[HOST]
Internet support new encryption
-secureplugin -connect localhost:5500 -noregistry
Viewer
Make sure the viewer use also SecureVNCPlugin.dsm and call the viewer key SC_Viewer_ClientAuth.pkey
if only one pkey exist you don't have to rename it.

Tried to reproduce... Created new key pair, put SC_Viewer_ClientAuth.pkey into my 1.3.2 Viewer x64 with DSMPlugin x64... Generated new SC with SC_Server_ClientAuth.pubkey...
After several seconds of "Negotiate protocol version" I'm getting Server closed connection -ManualClosed -Network disconn message in the viewer...

I thought maybe I have a conflict with other keys I have in my Viewer, so I randomly renamed SC_Viewer_ClientAuth.pkey to -SC_Viewer_ClientAuth.pkey
And for some reason VNC OC managed to connect with encryption this time... Ummm... What???
While laughing, I tested other symbols in front of SC_Viewer_ClientAuth... Adding letters does not work (Server closed connection), but any numbers do... Exclamation mark works, but underscore does not...

When I use SC_Viewer_ClientAuth.pkey and try to connect, vncviewer in listening mode often crashes... I have tons of vncviewer crash logs:
Exception 0xc0000005 in SecureVNCPlugin64-tmp.d1_unloaded version 2.4.1.0

Reverting to version 2.4.0.0 of DSMPlugin (published on this site) resolved viewer crashing issue, but didn't help with connecting if the key is named "SC_Viewer_ClientAuth.pkey"...

In the end, it was fun, but this setup is still suboptimal because there's no file transfer, no chat, and no support for most encoders... I would really like Tight or Ultra2 support in SC for helping those people who have slow internet connection... Right now it only seems to use ZRLE or Hextile...

UPDATE: Now I wonder, where did I get that v2.4.1 plugin?.. I can't find it anywhere on the Internet... And I've just discovered that it crashes the server too when I click the Config button... Hmmm... Version 2.4.0 is fine, though...

Verified.
2.4.1 is the dsm plugin that's used for more then a year.
It was a security update of the openssl version.

It's the plugin that get installed whet you run the setup.

It's also the plugin i used to test SC and the vncviewer

Rebuilding plugins with Opelssl-1.1.0f and also 1.1.1i

https://www.uvnc.eu/download/132/Secure ... 1.1.1i.zip
https://www.uvnc.eu/download/132/Secure ... 1.1.0f.zip

I can repeat the crashed with any version, can you verifi if this behave better.

1.1.1 openssl libs, own build
1.10 prebuild libs

Tested SC connection, even generated the new key pair for that – and got the same results – Connection closed error if the pkey is named as it should be, and normal connection if I rename it to -SC_Viewer_ClientAuth.pkey or 1SC_Viewer_ClientAuth.pkey... (This is a weird bug)
With the normal client/server both your new versions don't seem to crash through loopback at least... They also seem to operate well with older 2.4.0 server... Cannot test more, very drunk now... Happy New Year!..
