Preface:
I asked myself, how to get our appliances into ZENworks Service Desk, while I wanted to configure outages. Creating them manually wasn’t an option. So getting the Linux Inventory Agent installed on an appliance was the idea. Then I found an article from ethanspoelstra, who described installing the full agent on linux. I took some parts from his appnote.

Get ZENworks Inventory Only Agent
Installing the ZENworks Inventory Only Agent on a Linux server through SSH
Log into the appliance through SSH. I use Putty, while doing it through a Windows box. This requires an appliance to have SSH activated through the admin interface.

Now change directory ‘cd’ to the /tmp folder.

zsd:/# cd /tmp

Use ‘wget’ to download the ZIOA installer. The syntax varies based on whether you are using a self signed certificate or not. If you have a self signed certificate you will need to use --no-check-certificate as an option. For example: ‘wget --no-check-certificate https://path-to-agent’

Otherwise you can simply wget the file without the --no-check option. See appendix A for the ZIOA example links to use with ‘wget’ for x86 and x86_64 in ZCM 20.1.0.

zsd:/tmp # wget --no-check-certificate https://your.servername.here:port:443/zenworks-downloads/inventory/Linux/ZENworks_Inventory_Only_Agent_Linux_x86_64.tar.gz

Get lsb-release RPM

The install script tries to determine the operating system, but this rpm isn’t provided on the appliances. In this example I will download the generic rpm for SLES12 boxes

zsd:/tmp # wget --no-check-certificate https://download.opensuse.org/repositories/home:/efagra:/SLE12/SLE_12/noarch/lsb-release-2.0-24.1.1.noarch.rpm

Extract ZENworks Inventory Only Agent

zsd:/tmp# tar -xopf ZENworks_Inventory_Only_Agent_Linux_x86_64.tar.gz

Switch to the directory

Zsd:/tmp# cd ZENworks_Inventory_Only_Agent_Linux_x86_64

And run the script

zsd:/tmp/ZENworks_Inventory_Only_Agent_Linux_x86_64 # ./install.sh
