Hi, All, When Using a Server by Radius Authtication, always failed, check in Radius Server by Radius -A -X , see below. rad_recv: Access-Request packet from host 10.10.7.190:5672, id=0, length=87 User-Name = "tester" User-Password = "\010\n\rINCORRECT" NAS-IP-Address = 10.10.7.190 NAS-Identifier = "sshd" NAS-Port = 4647 NAS-Port-Type = Virtual Service-Type = Authenticate-Only Calling-Station-Id = "10.10.7.5" But if other client using same radius server authticate with same username and pasword, the "User-Password" field is in clear text and all works. Could some one look this for me, many thanks.
