Hi,
already try that syntax but the same is not the syntax that I need, know any others? or there is no other place?
all you random new people who are mysteriosuly asking for this MAC authentication....whatever course you are on, please reprimand the organiser for not having local help/hints/cribs to help you out. a public mailing list is not a commercial course support structure! fix: run FreeRADIUS in debug mode radiusd -X look for the request, and note the form of the User-Name then, in users file, add the User-Name, followed by Cleartext-Password, operator := and the User-Name again eg 00-11-22-33-44-55 Cleartext-Password := "00-11-22-33-44-55" or 001122334455 Cleartext-Password := "001122334455" - this sort of thing will depend on your NAS kit installed and what method you are using... eg for 802.1X wireless you cannot do this. alan
