Disable confirmation dialog for opening external application on EVE-NG

May 21, 2020 k2hiro Windows 0

If you use Chrome browser, you may feel annoyed seeing the confirmation dialog every time you click a node to open a console on EVE-NG virtual lab.

You can disable it by adding a key to windows’ registry. Save below texts as a .reg file and double-click it to install.

Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Google\Chrome]
"ExternalProtocolDialogShowAlwaysOpenCheckbox"=dword:00000001
[HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Edge]
"ExternalProtocolDialogShowAlwaysOpenCheckbox"=dword:00000001

Now you will see a checkbox in the dialog as below.

Once it is checked, the dialog will no longer pop up for the same application.

The steps above no longer work in the latest versions of Chrome/Edge browsers. You need to import the following keys in your registry.

[HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Google\Chrome\URLAllowlist]
"1"="telnet://*"
"2"="capture://*"
