Configuring Juniper Steel Belted Radius to grant exec and or enable access to Cisco IOS device

Scenario

Using the plug-in modular nature of PAM we can get a linux server to use RADIUS to authenticate users connecting via SSH. This guide tells you how to setup a Centos 5.2 server as your Radius "client" and Juniper Steel-Belted as your radius server authentication "server". We are going to use the pam_radius_module from free radius to provide the mechanism of authenticating ssh logins against a radius box.

For this example my environment consists of

A centos 5.2 radius client called "cyclone"
A Steel-Belted Radius server is called "turbo"
