Problem with radzap

Hello, I have a mistake with my freeradius. On server with 1.1.7 the command : "radzap -u username -P port-nas 127.0.0.1 secret" work with no problem On a new server with FR 2.0.5, with the same command i have this error radclient:: failed to get value I have no more message with the "-x" option and nothing in the log. I have the same things if i replace "127.0.0.1" by "localhost" my client.conf client localhost { ipaddr = 127.0.0.1 secret = secret require_message_authenticator = no shortname = localhost nastype = other # localhost isn't usually a NAS... } I don't understand. Thanks for your help. ph
