Other ways to set the IP address (for advanced users and
administrators)
For information on how to configure your machine for a network using the BRAdmin Professional utility or a
web browser, see
Setting the IP address and subnet mask on page 2-3.
Using DHCP to configure the IP address
The Dynamic Host Configuration Protocol (DHCP) is one of several automated mechanisms for IP address
allocation. If you have a DHCP server in your network, the print server will automatically obtain its IP address
from DHCP server and register its name with any RFC 1001 and 1002-compliant dynamic name services.
Note
If you do not want your print server configured via DHCP, BOOTP or RARP, you must set the BOOT
METHOD to static so that the print server has a static IP address. This will prevent the print server from trying
to obtain an IP address from any of these systems. To change the BOOT METHOD, use the BRAdmin
Professional utility.
Using BOOTP to configure the IP address
BOOTP is an alternative to rarp that has the advantage of allowing configuration of the subnet mask and
gateway. In order to use BOOTP to configure the IP address make sure that BOOTP is installed and running
on your host computer (it should appear in the
/etc/services file on your host as a real service; type man
bootpd or refer to your system documentation for information). BOOTP is usually started up via the
/etc/inetd.conf file, so you may need to enable it by removing the “#” in front of the bootp entry in that
file. For example, a typical bootp entry in the /etc/inetd.conf file would be:
#bootp dgram udp wait /usr/etc/bootpd bootpd -i
Depending on the system, this entry might be called “bootps” instead of “bootp”.
