How to Install FreeRADIUS and Daloradius on Ubuntu 20.04
FreeRADIUS is a free open source server for UNIX and Unix-like operating systems that allows one to set up a RADIUS protocol server. You also need a correctly configured client that communicates with the server when you want to use it, which could be used for authentication or accounting various types of network access. Sample applications are hotspots, VPN protocols such as OpenVPN, Strongswan, or SoftEther (Wireshark) on an Android smartphone.
