kppp – A kde GUI frontend for pppd.; gnome-ppp – A (discontinued) gnome GUI frontend for WvDial, which in turns depends on pppd.; pppconfig – It uses the standard ppp configuration files and sets ppp up so that the standard pon and poff commands (to connect and disconnect) and plog (to list the log) can be used to control ppp.
PPP is a layered protocol that has three components: [4] An encapsulation component that is used to transmit datagrams over the specified physical layer. A Link Control Protocol (LCP) to establish, configure, and test the link as well as negotiate settings, options and the use of features.
Packet Tracer is a cross-platform visual simulation tool designed by Cisco Systems that allows users to create network topologies and imitate modern computer networks. The software allows users to simulate the configuration of Cisco routers and switches using a simulated command line interface.
It is used mainly with DOCSIS and DSL carriers, by encapsulating PPP frames in ATM AAL5. Point-to-Point Protocol over Asynchronous Transfer Mode (PPPoA) is specified by The Internet Engineering Task Force (IETF) in RFC 2364. [1] It offers standard PPP features such as authentication, encryption, and compression.
In setting up PPP communications, both the sending and receiving devices send out LCP packets to determine the standards of the ensuing data transmission. The protocol: checks the identity of the linked device and either accepts or rejects the device; determines the acceptable packet size for transmission; searches for errors in configuration
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.
A PPP endpoint can request a specific IP address from its peer. It can also ask the peer to suggest an IP address by requesting the address 0.0.0.0; the peer then sends its suggestion in an IPCP Nak packet, which the first peer must subsequently request in order to complete the negotiation.
In computing, the Challenge-Handshake Authentication Protocol (CHAP) is an authentication protocol originally used by Point-to-Point Protocol (PPP) to validate users. CHAP is also carried in other authentication protocols such as RADIUS and Diameter. Almost all network operating systems support PPP with CHAP, as do most network access servers.
