Netdisco on Ubuntu 24.04 LTS

Netdisco on Ubuntu 24.04 LTS

Netdisco is an open source, web based network management and discovery tool for small to very large networks. It polls your switches, routers and access points over SNMP (and CLI or device APIs), collects IP and MAC address data into a PostgreSQL database, and presents a web interface to inventory every device, browse and search ports and nodes, locate where a given MAC or IP address is connected, and view how devices link together. Network and operations teams use it to answer questions like which switch port a machine is on, what changed on the network, and where unused ports are.

This cloudimg image is a complete, self contained appliance on first boot. Netdisco 2.101000 runs from the official netdisco/netdisco Docker images (a web frontend and a backend poller daemon) behind an nginx reverse proxy on port 80, backed by a bundled local PostgreSQL 16 database that already holds Netdisco's schema and the MAC vendor (OUI) reference data, so device and node vendors are identified out of the box.

Secure by default. Netdisco ships by default with an anonymous guest that has full admin rights. This image disables that guest, so a real login is always required. On the first boot of every VM a one shot service generates a unique admin password, a unique PostgreSQL password and a unique SNMP read only community, and writes the login to a root only file. No usable credential ships in the image. The bundled database listens only on loopback and is never exposed to the network.

What is included:

• Netdisco 2.101000 (BSD-3-Clause) run from the official netdisco/netdisco Docker images, managed by systemd units
• Netdisco published on port 80 via nginx, with a web frontend and a backend SNMP poller
• A bundled local PostgreSQL 16 database with Netdisco's schema and MAC vendor (OUI) reference data preloaded
• The default anonymous admin guest disabled, and a per VM admin login generated on first boot
• A unique admin password, PostgreSQL password and SNMP read only community generated on first boot
• Fully patched Ubuntu 24.04 LTS with unattended security upgrades enabled
• A paired step by step deployment guide and 24/7 cloudimg support

Licensing: Netdisco is BSD-3-Clause licensed and free. The cloudimg charge covers packaging, security patching, image maintenance and 24/7 support. Netdisco serves plain HTTP on port 80 in this image; front it with TLS and your own domain before production.
