server running FreeRADIUS. Rackspace typically puts a Cisco ASA firewall in
front of a customer’s Linux server. When you ran the nc test, was the system
that you ran nc from on the same network with the Linux server running
FreeRADIUS? They both might have been behind the same firewall. Check with Rackspace
to see if there is a Cisco Firewall in front of your Linux server.<o:p></o:p></span></p>
