Access control and authentication: Using protocols like Challenge-handshake authentication protocol (CHAP) or Password authentication protocol (PAP) it has to provide and check authentication data. Layer 3 configuration: If using Internet Protocol Control Protocol (IPCP), it will negotiate or determine IP parameters such as the IP addresses ...
Password Authentication Protocol (PAP) is a password-based authentication protocol used by Point-to-Point Protocol (PPP) to validate users. [1] PAP is specified in RFC 1334. Almost all network operating systems support PPP with PAP, as do most network access servers. PAP is also used in PPPoE, for authenticating DSL users.
The Point-to-Point Protocol over Ethernet (PPPoE) is a network protocol for encapsulating Point-to-Point Protocol (PPP) frames inside Ethernet frames. It appeared in 1999, in the context of the boom of DSL as the solution for tunneling packets over the DSL connection to the ISP's IP network, and from there to the rest of the Internet.
For example, IP uses IPCP, and Internetwork Packet Exchange (IPX) uses the Novell IPX Control Protocol . NCPs include fields containing standardized codes to indicate the network layer protocol type that the PPP connection encapsulates. The following NCPs may be used with PPP: IPCP for IP, protocol code number 0x8021, RFC 1332
Tools exist to trivially extract the NT Password hashes from a captured MSCHAP-v1 exchange. [6] When using MS-CHAP-v1, MPPE uses the same RC4 session key for encryption in both directions of the communication flow. This can be cryptanalysed with standard methods by XORing the streams from each direction together. [7]
If the resulting hashes match, then the user is deemed to be authenticated. If the hashes do not match, then the user's authentication attempt is rejected. Since the authentication server has to store the password in clear-text, it is impossible to use different formats for the stored password. If an attacker were to steal the entire database ...
Requests the direct IP address of the user with the specified nickname. This command is often used to obtain the IP of an abusive user to more effectively perform a ban. It is unclear what, if any, privileges are required to execute this command on a server. This command is not formally defined by an RFC, but is in use by some IRC daemons.
PPP configuration generally includes: user credentials, user name and password, and is unique to each user. ATM configuration includes: Virtual channel link (VCL) – virtual path identifier and virtual channel identifier (VPI/VCI), such as 0/32 (analogous to a phone number)
