Configuring WAN connections

WAN software

UnixWare provides the following facilities for data communication over WANs:


Basic Networking Utilities (BNU)
The BNU software includes the UNIX-to-UNIX system copy (UUCP) facility for remote file transfer and command execution. It also provides the foundation for remote login commands such as cu(1bnu) and ct(1bnu), as well for as the SLIP and PPP protocols. These protocols allow the establishment of network layer protocols such as the Internet Protocol (IP) over WAN connections.

The BNU software on its own does not provide support for running network layer protocols over point-to-point links. It must be used in conjunction with SLIP or PPP to achieve this.


Serial Line Internet Protocol (SLIP)
The SLIP protocol allows the transmission and reception of IP datagrams over point-to-point links. It has been superseded in many respects by PPP.

Point-to-Point Protocol (PPP)
The PPP protocol allows the transmission and reception of network packets over point-to-point links. Unlike SLIP, however, it has the potential of supporting network layer protocols other than IP. PPP also provides many other features that are not available with SLIP.
