Hi,
I think I have my radius server configured properly (I followed the configuration advice in http://tldp.org/HOWTO/html_single/8021X-HOWTO/).
I can get it running (using radiusd -X) and see all the expected output.
Please post this output, even if it's just the server startup info.
I have also configured my AP to point to the correct location, and it is pingable from the radius server.
So, the AP is configured with the RADIUS server's IP, you have configured your FR "clients.conf" file with the APs information and the shared secret is correct on both devices?
Does your AP have any ping functionality? If so, can it ping the RADIUS server? Does the AP provide any logging data indicating it connected to the RADIUS server? Sounds suspiciously as if the RADIUS box's firewall settings may be at fault.

However, when I try to connect, user validation always fails. And the radius server (which is in debug mode) doesn't show me anything. It's like nothing is connecting to it at all. I also tried to test it using NTRadPing, and his won't connect either.
Any help or suggestions here would be appreciated. I am running version 1.1.1 of freeRADIUS.
Thanks,

If the server is running, nmap *will* say that the port is open on localhost. In any case, the definitive answer is that an external nmap says it's filtered. Delete the firewall rules that block the RADIUS ports. Alan DeKok.

When I run nmap on the Radius server, just watching port 1812, I get conflicting results depending on what machine I run nmap on. When I test the port from the client machine, it returns saying the port is filtered, but when I run nmap on the actual server, === message truncated ===
If you're not seeing any output after "Ready to process requests." then the packets aren't making it to FR. Rather than looking at packet level information, it may be of more value to look at the firewall details. If you're running iptables, for example, "iptables -L -v --line-numbers" will give you a clear and detailed view of what the firewalling is blocking and allowing. If this server does not have any interfaces exposed to the public Internet, try turning off the firewall completely and test (be sure to turn it back on though :) Laker __________________________________________________ Do You Yahoo!?
