Hi All, I want to use the Radius Server where the requesting Client are IPv6 Host. I have changed the clients.conf like : client 2001:0:0:1::9 { secret = pass shortname = admin } I have changed the users file: vikas User-Password == password Service-Type = Administrative-User But, the RADIUS SERVER is showing: rlm_pap: WARNING! No "known good" password found for the user. Authentication may fail because of this. I have enabled the IPv6 connection line form radiusd.conf file. Is am i require to do any changes which impact of responding to ipv6 client host THANKS IN ADVANCE...I am waiting for early reply. Thanks Vikas S --------------------------------- Got a little couch potato? Check out fun summer activities for kids.
