UltraVNC

UltraVNC is one example of a VNC Server and Client, a standard means of remote access.

Running VNC server software on Windows allows you to connect to the Windows graphical environment using VNC client software on a remote computer. There are various VNC client and server softwares, such as TightVNC and UltraVNC. There are VNC clients for probably every operating system, so you don't need to be running Windows to connect to and use Windows. VNC uses the RFB protocol, a defined standard method for remote access, so generally speaking any VNC client will connect to any VNC server, however occasionally some VNC implementations have added non-standard features that other clients may not support, examples of this are UltraVNC's remote login and file transfer features.

VNC clients connect into the session currently running on Windows, so the remote user and the person who might be sat at the computer see the same thing; the client doesn't get a separate login prompt, if someone is already logged into the computer then you see that, otherwise you get to login.

For remote administration or remote staff working, for security reasons you are strongly advised not to enable remote access to desktop computers directly over the Internet, instead you should have a firewall in place (for example pfSense), running a VPN server, which clients are required to securely VPN into before they have unfettered access to connect to VNC on desktop computers running Windows (or other operating systems).

[edit] Package for UltraVNC 1.1.8 x86/x64

This is a modification of the 1.1.7 example below. In theory, this should work on XP/Vista/Win7 32-bit and 64-bit architectures, but it's only been tested on WinXP x86 and Win7 x64 so far.

This version will also set your (pre-encoded) password in ultravnc.ini using "replacetext.vbs", which can be found [here]. Note that I've set the %VNC_PASSWORD% variable in the profiles/userprofile.xml for security reasons, but you can create a variable directly in the package definition.

You need four setup files: UltraVNC_1_1_8_x64_Setup.exe, UltraVNC_1_1_8_x64_Addon.exe, UltraVNC_1_1_8_x86_Setup.exe and UltraVNC_1_1_8_x86_Addon.exe.

You also need to create two .inf files for unattended installation - one for the main installer, one for the addons installer. Run both the main installer and the addons installer from the command line using the argument "/saveinf=filename". Customize your installation as you like, and the .inf file will record your preferences. You should be able to use the same .inf files for both x86 and x64 installations. Save both .inf files in your install directory.

Once UltraVNC is installed, configure it however you like, then copy the %PROGRAMFILES%\uvnc bvba\UltraVNC\ultravnc.ini file to your install directory. If you want to set your password via replacetext.vbs, replace the password with the value "CHANGEME".

For the mirror Driver you need three Windows files: devcon.exe (x64 and x86 version) and certmgr.exe. You can find these via Google. To get rid of the certificate warning from Windows 7 during the driver Installation we need the .cer file.

You can extract it after installing the driver ona test machine. Right click on the file %PROGRAMFILES%\uvnc bvba\UltraVNC\driver\driver\mv2.cat -> properties -> digital signature -> Details -> View Certificate -> Details ->Copy to File and export the DER-formatted .cer file. After the Installation I had the problem that the driver wasn´t recognized by the System. So i manually had to update it with the devcon.exe.

In the end there should be two Setup.exe, two addon.exe, two .inf files, two .cer files, certmgr.exe and two versions of devcon.exe in your setup folder.

[edit] Package for UltraVNC 1.1.7 x64

This builds slightly on the example from 1.0.6.4 and was tested with Windows 7 x64 Clients.

You need UltraVNC_1_1_7_x64_Setup.exe and UltraVNC_1_1_7_x64_Addon.exe and create two install files (installer.exe /saveinf=file for both Setup and Addon). For the mirror Driver you need two Windows files certmgr.exe and devcon.exe (x64 Version) which you can find via Google. To get rid of the certificate warning from Windows 7 during the driver Installation we need the .cer file. Extract it from the setupdrv.exe (Right click on the file %PROGRAMFILES%\uvnc bvba\UltraVNC\driver\driver\mv2.cat -> properties -> digital signature -> Details -> View Certificate -> Details ->Copy to File). After the Installation I had the problem that the driver wasn´t recognized by the System. So i manually had to update it with the devcon.exe.

In the end there should be the Setup.exe, addon.exe, both .inf files, .cert file, certmgt.exe and devcon.exe in your setupfolder.

[edit] Windows Firewall

[Note: This may not be necessary as of UltraVNC 1.1.8.]

When installing silently the Windows Firewall won't prompt you to allow the VNC Server. You can script allowing traffic to the VNC server (on TCP port 5900, from all sources) using:

:: allow incoming TCP connections to port 5900 
netsh advfirewall firewall add rule name="VNC SERVER" dir=in protocol=TCP localport=5900 action=allow

old command (out-of-date)

netsh firewall add portopening TCP 5900 "VNC server" enable all
