4.3 Network Communication
An IRIS workstation can communicate with other devices over an Ethernet
local area network using the XNS and TCP/IP protocols. Only one
communication protocol can be used at one time.
The following sections present a brief overview of the commands used for
communicating over the Ethernet. For more information about the network
software for the IRIS workstation, see the manual pages for these commands in
the U
nix
Programmer’s Manual, Volume IA . To make the workstation emulate a
terminal, see Chapter 5.
The following two sections use these terms:
• A network is a collection of computers and terminals connected together.
• A host is a computer on a network.
• A local host is the host you are using.
• A remote host is another computer on the same network.
4.3.1 XNS Network Commands
To communicate over an XNS Ethernet local area network, the IRIS workstation
uses three commands:
xcp Copies a file from one computer to another.
xx Runs a command on a remote host.
xlogin Initiates a login on a remote host.
xcp copies a file from one host to another. The command line specifies both the
source host and file first, followed by the destination host and file:
xcp [
sourcehost:
]
pathname
[
destinationhost:
]
pathname
If no host name is specified, the local host is assumed. In these examples, the
user must have an account with the same user name on both hosts.
xcp sqiral.c olympus:/oh4/doc/install/sqiral.c
This example copies the file sqiral.c in the current directory of the local machine
to the file sqiral.c in the directory /oh4/doc/install on a host named olympus .
xcp sting:/usr/include/stdio.h test
This example copies the file /usr/include/stdio.h from a remote machine sting to
the file test on the local machine.
xcp puppy:temp_vi sting:temp_vi
