The message type of CHAP and the random number of R2. The second is to put the random number and the key on your own side (this key fact is a pre-shared key pre-negotiated by R2 and R1) into the MD5 key generator for MD5 calculation, then extract a digest message from the MD5 calculation result.

Preface: Today I saw the chap certification experiment of the Yan brothers. I think I helped my classmates solve a problem about pap and CHAP authentication, now we will summarize the PAP and CHAP authentication in PPP. Lab level: aassistant lab topology:

I. Prerequisites: 1. PPP definition: Point to Point Protocol (PPP) is an IETF (Internet Engineering Task Force, Internet Engineering Task Group) launched the data link layer protocol for point-to-point lines. This protocol is not a proprietary protocol and can connect devices of different vendors. Supports multiple protocols, optional authentication services, various data compression methods, dynamic address negotiation, and multi-link bundling. 2. PP
PAP (Password Authentication Protocol) is a simple plaintext authentication method. NAS (Network Access Server) requires users to provide user names and passwords, and PAP returns user information in plaintext. Obviously, this authentication method is less secure. A third pa
Through understanding the PPP protocol, we also entered the configuration phase. We know that the PPP protocol (point to point protocol) is the predecessor of the point-to-point protocol, SLIP, the PPP protocol provides a standard method for encapsulating multiple network data packets on point-to-point links. Now we will focus on the configuration of PPP protocol and PAP authentication.

Java Implementation of Radius secondary verification based on RSA securID (PAP authentication method) and securidradius
Secondary Verification Based on rsa SecurID. The RSA server itself can be used as a Radius server, RSA can also be used with other software sets, and other servers can be used as a Radius server.
The general process of radius verification is as follows:

Then, use a SIP client to register it with your Asterisk. What happened?You will find that the client can also be registered!
In fact, the true significance of type lies in how the asterisk processes requests sent to and from the external.Type = p
