I guess you didn't type " radtest username password localhost 0 sharedsecret" but " radtest username password localhost 1812 sharedsecret" why send it to the port 0? richard Bai <baixin@gmail.com> wrote: Hi, everyone, I face a very strange problem right now when I configure a freeradius server with PEAP + LDAP. I can start the radius in debug mode properly. I get following lines: Listening on authentication *:1812 Listening on accounting *:1813 Ready to process requests. Then I did test by using " radtest username password localhost 0 sharedsecret" And the radius server replied with Access-Accept message. So, I think the serve works just fine. But when I tested by using "radtest username password IP of server 0 sharedsecret" from a client conneted to the server through a hub, I can not get anything back. I even did not see any Access-Request information in debug mode on the radius server. It looks like the radius doesn't receive anything. However, I sniffered the interface via Ethereal and used " tcpdump -v port 1812 " in the server, I do see the Access-Request packet received by the interface on the server, I confirmed that the 1812 port is open. Please give me some idea. Any advices or solution is welcome. Thank you very much! Best Regards Richard - List info/subscribe/unsubscribe?
