7.1 Functional Overview
A host is addressed by its world-wide unique
hardware address
. This hardware address is pre-set in
the network interface of the host by the manufacturer.
On the Internet protocol level the host is addressed by its
Internet address
. This address consists of
four address groups which are separated by a period and which have values between 0 and 255. The
Internet addresses in a local network must be unique and assigned by the system administrator.
On the user level, the host is normally addressed by its name which can be chosen by the user. This
hostname
is used at user level by network services like FTP (File Transfer Protocol).
Before installing the print server into your network you must determine all parameters needed or ask
your system administrator for the values. All changeable parameters may be loaded, edited and saved
in the
params
file using
ftp
.
Printer Hardware Address
This address is pre-set by the manufacturer and can be found on the print server (refer to the
Appendix). The address consists of 12 hexadecimal numbers divided into 6 address groups of two
numbers each. The first three address groups designate the manufacturer of the network board. The last
three address groups stand for the individual board.
Example:
If you see the hardware address 00c0eb0001ff on your print server, the manufacturer code is 00c0eb,
while 0001ff is the individual number of your print server.
For better readability, the 6 address groups of the hardware address are normally separated in by a
period or a colon in data entries. In our example, it would be written:
00.c0.eb.00.01.ff or 00:c0:eb:00:01:ff.
Hostname of the Print Server
This entry is the hostname by which the print server will be addressed in the local network. You may
choose any name, but it is recommended to use a name which has some connection to the network
board or printer used.
Internet Address of the Printer
The Internet address is the address by which the printer will be logically addressed in your local
network. This address may not be used more than once in your local network. No other restrictions are
made, but it would be better to ask your system administrator for a free network Internet address. An
Internet address is marked free if this address is not entered in the
/etc/hosts
file on any of the
local network computers.
A 4 Byte long Internet address is made up of a Network ID and a Host ID. However, the address
depends on the network classification used; in a classification C network, the Network ID is formed by
the first 3 Bytes of the Internet address.
Example:
You have a Network ID of classification C and you have been allocated the Network ID 192.0.0. The
Host IDs 0 and 255 are reserved for broadcast addresses. So your valid Internet addresses lie in the
range from 192.0.0.1 to 192.0.0.254, for example 192.0.0.123.
