BOOTP Service
The bootpd Configuration File
• Maximum number of hops that the client’s boot request can be
forwarded
Syntax of bootpd Configuration Entries
An entry in the bootpd configuration file consists of a single line with
the following format:
hostname:tag=value tag=value tag=value
The hostname is the actual name of a BOOTP client and the tag is a
two-character case-sensitive symbol. Most tags are followed by an equal
sign and a value, as shown above, though some tags do not require a
value. The BOOTP daemon uses these tags and values to recognize a
client’s boot request, supply parameters in the bootreply to the client, or
relay the boot request.
For example, here is an entry for client printer01:
printer01: ht=ether: ha=080009030166: ip=15.19.8.2:\\
sm=255.255.248.0: gw=15.19.8.1: bf=/printer01
This entry tells bootpd that the host printer01 uses an Ethernet
network interface (ht=ether) whose hardware address (ha) is
080009030166. The IP address (ip) is 15.19.8.2, the Subnet mask
(sm) is 255.255.248.0, and the address of the gateway (gw) is
15.19.8.1. The bootfile that tftpd will transmit to boot this printer
(bf) is /printer01.
