System Requirements
Hardware
The hardware you need depends on the number of subscribers and on how busy your network is (number of online users, routers and logins per minute). A small network needs a modest server; a network with tens of thousands of users needs much more CPU, RAM and fast storage.
Contact Snono support with your number of subscribers to get the right server size before buying hardware or a VPS.
General recommendations for every installation:
- A reliable, well-branded server (Dell, HP, Lenovo…) or a good virtual machine / VPS.
- SSD storage (fast disks matter more than disk size).
- A second disk (or Google Drive) for backups.
- A stable internet connection, required for license activation and updates.
- Plan for growth: it is easier to start with spare capacity than to move a busy server later.
Operating system
SAS Radius runs on Ubuntu 18.04. The ISO installs everything automatically. Don't upgrade the operating system to a newer Ubuntu release.
Network
| Traffic | Direction | Ports |
|---|---|---|
| RADIUS authentication and accounting | Routers → SAS Radius | UDP 1812, 1813 |
| Disconnect / CoA | SAS Radius → routers | UDP 1700 (or the port set in the NAS form) |
| Admin panel and user portal | Browsers → SAS Radius | TCP 80 / 443 |
| License, updates | SAS Radius → internet | license.snono.systems, update servers |
There must be no NAT between SAS Radius and the routers (use a VPN tunnel for remote routers).
