[OpenSIPS-Users] Rebooting a Linksys through OpenSIPS

[Matti Zemack]

Hi again,

 

Yes, we tried almost that (as we don't receive a cnonce nor nonce-count in the 401 from Linksys, we only get the qop="auth" which actually by the RFC forces us to use your suggested longer response code.).

We did try with an empty cnonce and nonce count= "nc=00000001" (or empty).

Without success.

 

/Matti

Hi Bogdan.

For our particular need, it looks like we need to send the response in a more complex way:

response = md5(HA1:nonce:nonceCount:clientNonce:qop:ha2)

Could you give us any hint about nonceCount and clientNonce parameters? Documentation is not very clear.

Thanks and regards.

Sergio.

Hi Matti,

Actually it is SIP auth, so digest auth (RFC 2617)
Shortly:
   HA1=MD5( auth_usernam ":" realm ":" passwd )

   HA2=MD5( method ":" ruri )

   response=MD5( HA1 ":" nonce ":"  HA2)


Regards,
Bogdan
