Server Configuration

A static IPv4 address with subnet mask and default gateway must be configured directly on the FDC server. DHCP - even with a static lease must be disabled.

DNS with public name resolution must be enabled. Use your internal DNS server rather than a public resolver such as 8.8.8.8 - using a public server may have compliance implications and will prevent resolution of internal hostnames. A DNS A record should also be created for the FDC server to support agent deployment.

Time synchronization must be configured and active. Ubuntu 24.04 includes systemd-timesyncd by default - verify it is active. Accurate time ensures logs are recorded in the correct order and that updates are applied correctly.

A unique static hostname must be assigned to the FDC server. Use hostnamectl to view or set the hostname. The hostname is stored at /etc/hostname.

All third-party software must be installed post-deployment, after the K3s and Rancher cluster has been initialized. It is recommended to disable antivirus or any other third-party security software before proceeding with FDC installation. If full disablement is not possible, configure the AV exclusions listed in the FDC Agent Requirements section below.
