I am using radius to authenticate request from the radiusclient-ng2 with the digest method. I have a strange situation because client log the following problem: "received invalid reply digest from RADIUS server" This is strange because as I read on web this error is due to wrong secrets configuration.
Yes. The shared secrets are wrong, or there is some miscalculation of the reply digest.
I checked a few times and secrets are the same I even tried to reinstall both freeradius and libradiusclient-ng2. Please help me and point what could be a reason for this??
Which OS are you running on? Is it 64-bit? What CPU? The libradiusclient code MAY be doing MD5 incorrectly.
here is my radius debug (maybe will help): rad_recv: Access-Request packet from host 127.0.0.1 port 32894, id=198, length=300 User-Name = "hellboy@voip.touk.pl" Digest-Attributes = 0x0a0968656c6c626f79 Digest-Attributes = 0x010e766f69702e746f756b2e706c Digest-Attributes = 0x022a34356264656531363664353437333838393736323162356564343730383331323661316461636633 Digest-Attributes = 0x04187369703a746f6d697840766f69702e746f756b2e706c Digest-Attributes = 0x0308494e56495445 Digest-Attributes = 0x050661757468 Digest-Attributes = 0x090a3030303030303031 Digest-Attributes = 0x08223639464435383136374435424646364631304633363746453943433138333339 Digest-Response = "2c8b62ee23ac6cbe4a551b8b698a509c" Service-Type = 0x0000000f00000000
That looks like a bug in libradiusclient. The Service-Type attribute should be 4 bytes of data, not 8.
SER-Service-Type = 0x0000000300000000 SER-Uri-User = "hellboy" NAS-Port = 0x000013c400000000 NAS-IP-Address = 0x7f00000100000000
Again, the NAS-Port & NAS-IP-Address attributes should be 4 bytes of data, not 8. This makes me suspect you're running on a 64-bit system, and that the libradiusclient code isn't 64-bit clean.
