Installing zDM Server

Summary

zDM (Device Management Server) is the CoAP/LwM2M proxy between zMAN Director and zTC endpoints. Install it after zMAN Director to enable device check-ins and command delivery :contentReference[oaicite:0]{index=0}.

Prerequisites

• Ubuntu 22.04 LTS on a dedicated VM: SSD ≥ 32 GB, RAM ≥ 2 GB, CPU ≥ 2 cores
• zDM binaries (e.g. zdm-deployment-x.x.x.7z)
• p7zip-full installed via sudo apt install p7zip-full

Procedure

1. Create and enter the install folder:

   mkdir ~/zDM && cd ~/zDM

2. Copy the zdm-deployment-x.x.x.7z archive into ~/zDM and extract:

   7z x zdm-deployment-x.x.x.7z

3. Run the installer:

   sudo ./zdm-setup.sh

   Choose option **1. Install zDM Server** and follow prompts :contentReference[oaicite:1]{index=1}.

4. When asked about certificates, enter **n** to generate a self-signed cert (or **y** to import your own).
5. Register with zMAN: choose **3. Register ManagementPortal** and provide:
   • zMAN Director URL (e.g. https://zman.example.com)
   • API Access Key (from zMAN → Server Configuration → API Access Key)
   • Local IP for zDM to listen on
6. Upon success, the new zDM appears in zMAN under **Server Configuration → zDM Management → Pending zDM**; click **Onboard** to complete integration.

Post-Install Verification

• Confirm the zdm-service is running: sudo systemctl status zdm
• Check that UDP 5683 is open between zDM and your zMAN host.
