HP CD-ROM Server User's Guide

Network Configuration 3-5
Choose the method best suited to your needs. If necessary, the
RARP, BOOTP and DHCP methods can be enabled or disabled
by editing the
RARPEnable
,
BOOTPEnable
and
DHCPEnable
parameters in the config.ini file as described in chapter 5
“CD-ROM Server Configuration”. See appendix B for default
values.
Note ❏
Only one of the RARP, BOOTP, DHCP methods for setting
the IP address should be enabled at the same time. If both a
BOOTP and a DHCP server on the network provides an IP
address, then the BOOTP address is used. If both a RARP
and a BOOTP or DHCP server provides an IP address at the
same time, the results are undefined.
In Windows NT,
Set the IP Address
Using ARP
In Windows NT, the IP address can be sent to the CD-ROM
server using an ARP command. Perform the following
commands from a DOS prompt to send the IP address to the
CD-ROM server and to verify that it was successfully
configured. Enter the LAN hardware address (specified on the
label attached to the bottom of the CD-ROM server). Each pair
of digits must be separated by a hyphen. See the example below:
Example:
The host will return ‘Reply from
192.124.138.80...
’ or similar
message indicating that the address has been set and that
communications with the CD-ROM server is established.
Note ❏
When you execute the ping command for the first time, the
response time may be longer than usual. The ping command
is used to write the IP address to the CD-ROM server.
❏
Once the CD-ROM server has communicated using its IP
address,
the
arp
and
ping
commands cannot be used to
change the IP address
. This inhibits accidental or
unauthorized changes of the IP address. To enable the CD-
ROM server to accept setting of the IP address using ARP,
you must restart it (cycle power).
arp -s <IP address> <LAN hardware address>
ping <IP address>
arp -s 192.124.138.80 00-60-b0-11-00-86
ping 192.124.138.80
