Best Top 25 Open Source RADIUS Server Solutions

In this article, we take a look at the top 25 open source RADIUS server solutions available for Linux, Windows, Unix and other platforms. 

Are you looking for a Remote Authentication Dial-In User Service (RADIUS) server to authenticate users for network access, authorize how much network access they are allowed, and account for all their activity on the network (Authentication, Authorization, and Accounting – AAA)? An AWS RADIUS server goes beyond your wired infrastructure, to your wireless clients giving them access to your network with their existing identities.

RADIUS Server applications are available with various features and at different price ranges. However, there are a number of open source alternatives that can be easily integrated into your system. You can benefit from the high-quality software, tech support, simple license management, and more services – all at a cost-effective price.

25. jquery locationpicker plugin

The JQuery Location Picker plugin allows easily finding and selecting a location on Google maps. Other than single point selection, it also allows area selection by providing a point and specifying a radius. All data can be saved onto any HTML input element or processed by Javascript with callback support. Another feature of this plug-in is automatic address resolver which allows getting an address from the selected latitude and longitude. The plug-in also supports searching by address typed into the bound input element which uses auto-complete feature from Google API to make the search process easier. Here, the marker will be automatically positioned on the map after successful address resolution.
