Hello Jamf Community,

 

iam looking for a Script to uninstall the Cisco Client Silent.

I have a script that does it, but the Users will always get a Pop-Up Message that the Socket Filter needs Admin Permission. You can ignore the window, and it is uninstalled, but I would like to have it more clean.

 

Greetings TGD

Are you running this script?

 

#!/bin/bash

/opt/cisco/secureclient/bin/cisco_secure_client_uninstall.sh

 

exit 0

If you use the XML custom setup, this pop-up doesn't appear. Would highly recommend but takes some time to setup. https://docs.umbrella.com/umbrella-user-guide/docs/customize-macos-installation-of-cisco-secure-clie...

Otherwise, I had to make a script to make the user an admin, install the software, remove the components (thousand eyes, DART, etc...), and then demote the user admin rights. This way the user can at least use their credentials to accept or cancel out. We found an issue with the umbrella going this route, that the umbrella wasn't active until after the first time the user connected to the VPN.

I used Suspicious Package https://mothersruin.com/software/SuspiciousPackage/ to copy out uninstall script(s) from the pkg installer(s). To make back up "clean up" removal policies when the normal process (invoke the uninstall script) fails.

Here's the VPN/VPN Socket removal script from the pkg (but won't remove the other module(s) from 5.1.2.42
