supported urls on the map by the host adding vnc:// ulr

[krzysztof.tech]

Hello, I have found a simple solution to add VNC web to the host on the map using Apache Guacamole. The link is below.

https://www.zabbix.com/forum/zabbix-...nc-integration

Now I've decided that it would be useful to add a link that automatically opens the VNC Viewer application.
So I made changes to the Windows registry that added support for the VNC:// protocol to the system, meaning that if I enter the address vnc://127.0.0.1 in my browser,
the application will open. Similarly, if I issue the command in Run, the application will open. The registry entry is shown below.

REGEDIT4

[HKEY_CLASSES_ROOT\vnc]
@="URL:VNC Protocol"
"URL Protocol"="http://www.realvnc.com/"

[HKEY_CLASSES_ROOT\vnc\DefaultIcon]
@="C:\\Program Files\\uvnc bvba\\UltraVNC\\vncviewer.exe,0"

[HKEY_CLASSES_ROOT\vnc\shell]

[HKEY_CLASSES_ROOT\vnc\shell\open]

[HKEY_CLASSES_ROOT\vnc\shell\open\command]
@="C:\\Program Files\\uvnc bvba\\UltraVNC\\vncviewer.exe -connect %1"

[HKEY_CLASSES_ROOT\vnc]
@="URL:VNC Viewer Protocol"
"URL Protocol"="http://www.realvnc.com/"

[HKEY_CLASSES_ROOT\vnc\DefaultIcon]
@="C:\\Program Files\\uvnc bvba\\UltraVNC\\vncviewer.exe,0"

[HKEY_CLASSES_ROOT\vnc\shell]

[HKEY_CLASSES_ROOT\vnc\shell\open]

[HKEY_CLASSES_ROOT\vnc\shell\open\command]
@="C:\\Program Files\\uvnc bvba\\UltraVNC\\vncviewer.exe"​

I will now explain what these changes consist of. In the Windows registry, I added a new entry called "VNC" in the "HKEY_CLASSES_ROOT" key.
Then, when adding a new entry, I set the value "URL:VNC Protocol" in the "HKEY_CLASSES_ROOT\VNC" key to the local VNC address, which in this case is "vncviewer.exe".
In this way, if I type "vnc://127.0.0.1" in the browser or in Run, the "vncviewer.exe" application will be launched.



And now, unfortunately, there is a problem. Zabbix by default only accepts http:// and https:// links, and it does not allow adding a vnc:// URL. I'm afraid it won't work without editing sysmap.php.

I tried to use "Scripts" and use Webhooks, but I couldn't come up with anything sensible. Does anyone have any ideas for a small modification?

Hello users, below is an improved registry entry for Windows 10/11. It is set by default to use UltraVNC viewer, so you need to install UltraVNC to use it.
Regarding adding support for the vnc:// url link to the Zabbix map, follow these steps:

Administration > General > Other > add "vnc" after a comma in the Valid URI schemes line.

That's it. The VNC password is included in the registry entry. If you remove the "-password YOURPASSWORD" string,
it will require a password when you connect.
You can also add additional options such as: -notoolbar -nostatus -quickoption 3.

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\vnc]
"URL Protocol"=""
@="URL:VNC Protocol"
"DefaultIcon"="\"C:\\Program Files\\uvnc bvba\\UltraVNC\\vncviewer.exe\",1"

[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\vnc\shell]

[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\vnc\shell\open]
"FriendlyAppName"="VNC Viewer"

[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\vnc\shell\open\command]
@="cmd /V:ON /C set address=%1 && set address=!address:~6,-2! && \"C:\\Program Files\\uvnc bvba\\UltraVNC\\vncviewer.exe\" -connect !address!-password YOURPASSWORD -8greycolors"
