Hello gents, I've been trying to solve this problem for a couple of days now. I'm asking for your expert advise since I'm not getting anywhere near a solution: The problem is when FreeRADIUS receives a Accounting-Request it drops the packet without response due to a problem with the signature: rad_recv: Accounting-Request packet from host x.x.x.x port 64514, id=1, length=287 Received Accounting-Request packet from x.x.x.x with invalid signature! (Shared secret is incorrect.) Dropping packet without response. The Access-Request are ok: rad_recv: Access-Request packet from host x.x.x.x port 64986, id=236, length=102 User-Name = "test" User-Password = "\2517Rq\2308Uv\"\204\220\341\377\244(\363" NAS-IP-Address = x.x.x.x NAS-Identifier = "NPR_GGSN_01" Called-Station-Id = "wap1.btcbahamas.com" Framed-Protocol = GPRS-PDP-Context Service-Type = Framed-User NAS-Port-Type = Virtual +- entering group authorize {...} ++[preprocess] returns ok ++[chap] returns noop ++[mschap] returns noop [suffix] No '@' in User-Name = "test", looking up realm NULL [suffix] No such realm "NULL" ++[suffix] returns noop [eap] No EAP-Message, not doing EAP ++[eap] returns noop ++[unix] returns notfound [files] users: Matched entry DEFAULT at line 61 ++[files] returns ok ++[expiration] returns noop ++[logintime] returns noop [pap] Found existing Auth-Type, not changing it. ++[pap] returns noop Found Auth-Type = Accept Auth-Type = Accept, accepting the user +- entering group post-auth {...} ++[exec] returns noop Sending Access-Accept of id 236 to x.x.x.x port 64986 The shared secret key has special characters in it such as $-sign and /-sign. The client is a Juniper NAS. These are the questions I have: - Any issues with FreeRADIUS Accounting-Request in combination with a secret key containing special characters? - Why is the access-request having no issues with these special characters? - Anyone bumped into a similar problems in combination with a juniper NAS - Is there a way to figure out the secret-key the client is using? Thank you. Regards, Shurbann Martes
