HP CD-ROM Server User's Guide

3-4 Network Configuration
Assigning an
IP Address and
Host Name
To establish communication with the TCP/IP network, an IP
address must be assigned to the CD-ROM server and, if
necessary, associated with a unique host name in your system
host table. The IP address must be sent to the CD-ROM server
to configure it.
If you are using host names, associate a host name with your IP
address using the appropriate procedures for your system
(consult your Network Administrator or refer to your system
manuals).
Sending the IP
Address to the
CD-ROM Server
The IP address can be sent to the CD-ROM server in several
ways, depending on your network operating system.
There are two manual methods:
• Editing the
config.ini
file for the CD-ROM server. This
requires that you already have network access to the
CD-ROM server (see chapter 5.)
• Using
ARP
– (Address Resolution Protocol). On supported
systems (Windows NT and UNIX), this the easiest method.
However, it requires that the IP address is sent to each new
device individually. The protocol is not routable, that is, the
workstation from which the configuration is made must be
located on the same network segment as the CD-ROM
server.
There are three automated methods:
RARP
,
BOOTP
and
DHCP
.
The main characteristics for each method are:
•
RARP
– (Reverse Address Resolution Protocol) downloads
the IP address to each device automatically. It requires a
RARP
daemon on your system. RARP operates within a
single network segment only.
•
BOOTP
– (Bootstrap Protocol) is similar to RARP, but
operates on the entire network. It requires a
bootp
daemon
on your system.
•
DHCP
- (Dynamic Host Configuration Protocol) allows for
the automatic but temporary assignment of IP addresses
from a predefined pool of addresses. In the absence of either
an active RARP or BOOTP daemon running on the host,
DHCP will, when enabled, cause the selected host to
automatically allocate and download a free IP address,
Default Gateway (Router) address and subnet mask to the
requesting CD-ROM server. It also provides data that
defines how long the IP addresses will remain valid.
