Hello! I recently want to configure a vpn server which is a radiusclient and send accept-request to freeradius for authentication! I create a vpn connection in windows 7 as a vpn client and try to connect to my vpn server. my vpn server is pptp on debian 7.6 and also install radiusclient1 inside pptp and config them through manual!I install freeradius on other debian os and config it. when I try to connect vpn connection to vpn server I entrance with 691 error. and when I run freeradius in debug mode with -X. i see : rad_recv: Access-Request packet from host 192.168.59.3 port 47804, id=118, length=63 Service-Type = Framed-User Framed-Protocol = PPP User-Name = "Deg" Calling-Station-Id = "192.168.69.2" NAS-IP-Address = 192.168.0.113 NAS-Port = 0 # Executing section authorize from file /etc/freeradius/sites-enabled/default +- entering group authorize {...} ++[preprocess] returns ok ++[chap] returns noop ++[mschap] returns noop ++[digest] returns noop [suffix] No '@' in User-Name = "Deg", looking up realm NULL [suffix] No such realm "NULL" ++[suffix] returns noop [eap] No EAP-Message, not doing EAP ++[eap] returns noop [files] users: Matched entry Deg at line 96 ++[files] returns ok ++[expiration] returns noop ++[logintime] returns noop [pap] No clear-text password in the request.
