Solaris PPP 4.0 (Overview)

This section covers serial networking topics. Serial networking refers to the use of a serial interface, such as an RS-232 or V.35 port, to connect two or more computers for data transfer. Unlike LAN interfaces, such as Ethernet, these serial interfaces are used to connect systems that are separated by large distances. PPP (Point-to-Point Protocol) and UUCP (UNIX-to-UNIX CoPy) are distinct technologies that can be used to implement serial networking. When a serial interface is configured for networking, it is made available for multiple users, in much the same way as any other network interface, such as Ethernet.

This chapter introduces Solaris PPP 4.0. This version of PPP enables two computers in different physical locations to communicate with each other by using PPP over a variety of media. Starting with the Solaris 9 release, Solaris PPP 4.0 is included as part of the base installation.

The following topics are discussed:
