Configure The Ip Address Using Bootp; Configure The Ip Address Using Rarp - Dell E515dw User Manual

Configure the IP Address Using BOOTP

Before you configure the IP address using Bootstrap Protocol (BOOTP), you must set the machine's Boot Method to
BOOTP. To change the Boot Method, use the machine's control panel Network menu.
BOOTP is an alternative to Reverse Address Resolution Protocol (RARP) that has the advantage of allowing
configuration of the subnet mask and gateway. To use BOOTP to configure the IP address, make sure 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 see 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".
NOTE: To enable BOOTP, use an editor to delete the "#" (if there is no "#," then BOOTP is already enabled) . Then edit
the BOOTP configuration file (usually /etc/bootptab) and enter the name, network type (1 for Ethernet), MAC
Address (Ethernet Address) and the IP address, subnet mask and gateway of the print server . Unfortunately, the
exact format for doing this is not standardized, so you will need to see your system documentation to determine how
to enter this information (many UNIX systems also have template examples in the bootptab file that you can use for
®
reference) . Some examples of typical /etc/bootptab entries include:
DELL310107 1 00:80:77:31:01:07 192.168.1.2
and:
DELL310107:ht=ethernet:ha=008077310107:\ip=192.168.1.2:
Certain BOOTP host software implementations will not respond to BOOTP requests if you have not included a
download filename in the configuration file. If this is the case, create a null file on the host and specify the name of
this file and its path in the configuration file.
As with RARP, the print server will load its IP address from the BOOTP server when the machine is powered on.

Configure the IP Address Using RARP

Before you configure the IP address using Reverse Address Resolution Protocol (RARP), you must set the machine's
Boot Method to RARP. To change the Boot Method, use the machine's control panel or Web Based Management.
The Dell print server's IP address can be configured using the RARP facility on your host computer. This is done by
editing the /etc/ethers file (if this file does not exist, you can create it) with an entry similar to the following:
00:80:77:31:01:07 DELL008077310107
where the first entry is the MAC Address (Ethernet Address) of the print server and the second entry is the name of
the print server. (The name must be the same as the one you put in the /etc/hosts file.)
If the RARP daemon is not already running, start it (depending on the system, the command can be rarpd, rarpd -a,
in.rarpd -a, or another command; type man rarpd or see your system documentation for additional information).
To verify that the RARP daemon is running on a Berkeley UNIX based system, type the following command:
®
ps -ax | grep -v grep | grep rarpd
For AT&T UNIX -based systems, type:
®
ps -ef | grep -v grep | grep rarpd
The Dell print server will get the IP address from the RARP daemon when the machine is powered on.
