Hi Mark, 

What does your /etc/radsec.conf file look like?

It should contain this:

realm gss-eap {
    type = "UDP"
    timeout = 5
    retries = 3
    server {
        hostname = "freeradius host name" (can be 127.0.0.1)
        service = "1812"
        secret = " radius secret"
    } 
}

Also, check that on CentOS, the firewall has ports 1812-1814 open. :-)

Stefan
