Tips

How to fix Chrome protocol handler “Always open these types of links in the associated app” pop up.

Windows

Save the following content in a .reg file and execute as an Administrator.

[HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Google\Chrome]
"ExternalProtocolDialogShowAlwaysOpenCheckbox"=dword:00000001

Note: the GNS3 all-in-one installer already does this.

Linux

Create the folders as needed.

sudo mkdir -p /etc/opt/chrome/policies/managed/

Create an empty JSON file.

sudo touch /etc/opt/chrome/policies/managed/managed_policies.json

Add the following content in this JSON file.

{
  "ExternalProtocolDialogShowAlwaysOpenCheckbox": true
}

MacOS

Run the following in a terminal.

defaults write com.google.Chrome URLWhitelist -array 'gns3+telnet://*' 'gns3+vnc://*' 'gns3+spice://*' 'gns3+pcap://*'
