System Requirements
Hardware (on-premise server)
| Item | Recommended |
|---|---|
| Server | A well-branded server (Dell, HP, Lenovo…) |
| CPU | At least 4 cores (more for large networks) |
| RAM | At least 8 GB (16 GB or more above 5,000 users) |
| Disk | 250 GB SSD (or SAS 15K) |
| Backup disk | A second disk for backups |
| Internet | Required for license activation and updates |
Large networks need more CPU, RAM and fast SSD storage; ask Snono support for sizing.
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).
