Introduction

Purists among you will note that the commands covered in this section are usually associated with TCP/IP and thus might organizationally have been included in that chapter. My justification for organizing them into two chapters is that these commands are concerned with accomplishing actual work in a network environment, whereas the commands in the TCP/IP chapter are more concerned with the infrastructure used to facilitate that work. Also the TCP/ IP chapter was getting awfully long.

The commands covered in this chapter include

`ftp`	Transfer files between networked machines.
`hostname`	Display or set name of host.
`netstat`	Display network usage information.
`ping`	Request confirmation packed from remote host.
`rarp`	Reverse Address Resolution Protocol.
`rcp`	Display remote copying service.
`rdate`	Get date information across network.
`rdist`	Distribute files across network.
`rlogin`	Login to remote computer.
`rsh`	Execute a remote shell.
`rusers`	Display network user information.
`rwall`	Write to all users on network.
`rwho`	Display network user information.
`telnet`	Display remote access to network host.
`tftp`	Display trivial file transfer protocol.
