: Provisions local instances of WireGuard, IPsec, and OpenVPN configurations. It handles the background architecture for UniFi Site Magic SD-WAN .
If a configuration change breaks connectivity (e.g., setting a wrong IP on the WAN port), advanced users can sometimes rescue the unit by editing the JSON file located at /mnt/data/udapi-config/ubios-udapi-server/ubios-udapi-server.state .
Restarting the server can sometimes break the loop. service ubios-udapi-server restart Use code with caution.
Ubios-udapi-server is the foundational software component responsible for managing networking services on Ubiquiti’s UniFi OS platforms. It serves as the bridge between the high-level UniFi Controller interface and the low-level Linux networking stack. 🛠️ What is Ubios-udapi-server? ubios-udapi-server
is a core background service (daemon) running on Ubiquiti’s UniFi Dream Machine (UDM), UniFi Dream Machine Pro (UDM-Pro), and UniFi Dream Router (UDR) product lines. It serves as the local API gateway and interaction layer between the UniFi OS (the operating system managing the device) and the UniFi Network Application (the controller software).
: It handles DHCP, DNS (via dnsmasq), Firewall rules (iptables/nftables), and Routing.
: It processes changes you make in the dashboard and writes them to configuration files for tools like (DNS/DHCP) and strongSwan Monitoring : Provisions local instances of WireGuard, IPsec, and
Handles local user sessions, API keys, and permissions – critical for scripts and third-party tools to interact securely with the UniFi OS.
: It acts as the configuration engine for the device.
: Ubiquiti Input/Output System (the localized firmware baseline). Restarting the server can sometimes break the loop
The daemon controls almost all Layer 3 (routing) and management plane activities on a UniFi gateway:
UDAPI implements a JSON-RPC 2.0 compliant interface for structured command execution. This ensures that commands sent from the controller (e.g., "Change Port 5 to VLAN 20") are executed transactionally.
