Need a quick freeradius server up and running on a 64bit CentOS 6.7 VM?
In a previous post I installed freeradius on a 32bit platform and it went very smooth.
Recently I needed to add freeradius service on a X86_64 machine and I noticed there are some differences in the install process.
If you need to stand up freeradius on a 32 bit machine use the instructions from my previous blog: http://thgtn.blogspot.com/2015/06/junos-space-and-free-radius.html
If you need to stand up radius on a X86_64 machine keep reading.
The process is pretty much the same from and I am currently using a CentOS 6.7 VM.
First, we need to grab the freeradius server and the freeradius-utils using the yum repositories.

SUMMARY
As you can see the radtest worked and the password was accepted by radiusd so we should now be able to start pointing network devices to the radius server.
