Configuring the Serial Line Internet Protocol (SLIP)

Configuring the Serial Line Internet Protocol (SLIP)

SCO SLIP is a STREAMS-based computer networking facility that provides for the transmission and reception of IP packets over serial lines. As such, SCO SLIP provides for the use of TCP/IP networking applications such as rlogin and telnet over serial lines. SCO SLIP is an implementation of the Serial Line Internet Protocol (SLIP) as defined in the following Internet documents: RFC 1055, RFC 1144.

Use SLIP when an Ethernet or Token-Ring network connection between the local host and another location is not possible but a serial line connection is. SLIP can be used to connect the local host to another host via a single, physical serial line connection between serial ports or over longer distances using telephone lines and modems. A computer that is running SLIP over one or more serial lines and that is also connected to a computer network (such as an Ethernet) can serve as a communication gateway between computers on the network and the computers at the far ends of the serial lines.

This chapter describes:

Also available for serial line communication, for use instead of SLIP, is PPP. See ``Configuring the Point-to-Point Protocol (PPP)'', for more information on PPP, and ``Serial line communications'' for a comparison of the two protocols.

SCO SLIP supports only asynchronous communications. SCO provides SLIP as a part of the discrete PPP package within the SCO TCP/IP runtime system. To use SLIP, you must either install the entire TCP/IP runtime system or ensure that PPP is one of the packages selectively installed.

Terminology used in this chapter:

as in serial line -- the physical medium over which data flows

as in SLIP link -- the virtual connection between two machines over which data flows

as in SLIP interface -- the abstract entity to which the IP driver routes datagrams
