Radclient is an open source Linux-based RADIUS client command-line program, included with the FreeRADIUS server. Its monitoring capabilities give you the ability to keep stats on up to hundreds of RADIUS servers and supports email alerts. Its debugging functionality displays and validates the raw RADIUS attribute packet information from your NAS or RADIUS server.

Its testing functionality lets you simulate RADIUS authentication, accounting and CoA/Disconnect requests with custom fields, built in counter variables, random characters and pseudo session IDs. You can use Radlogin to simulate, debug and monitor most RADIUS and Network Access Servers (NAS).

It’s developed by IEA Software, which also offers RADIUS servers and solutions. Radlogin is a free web-based RADIUS client, installable on Windows, Sparc Solaris, FreeBSD and Linux platforms. Then we’ll check out programs to help you better understand and validate the RADIUS and 802.1X security vulnerabilities. We’ll start by discovering a few RADIUS client programs that have an integrated authenticator and supplicant functionality, which allow you to easily test and monitor your RADIUS server from within a program and also see the RADIUS server responses.
