BOOTP/TFTP Concept
BOOTP / TFTP make it possible to configure network settings
for network printers and other devices from a
central BOOTP/TFTP server
My MAC is 0x080009000001. What’s my IP?
BOOTP broadcast/response
Use IP = 128.1.1.1

Enabling bootp and tftp Services
1. Enable BOOTP and TFTP services:
# /usr/sbin/setup_bootp
# /usr/sbin/setup_tftp -h
2. Verify that the services are defined in /etc/services:
# cat /etc/services
bootps
67/udp
tftp
69/udp
3. Verify that the services are defined and enabled in /etc/inetd.conf:
# cat /etc/inetd.conf
bootps dgram udp wait
tftp
dgram udp wait
root
root
/usr/lbin/bootpd
/usr/lbin/tftp
bootpd
tftp
4. Verify that the tftp account is defined in /etc/passwd:
# cat /etc/passwd
tftp:*:510:1:Trivial FTP User:/home/tftpdir:/usr/bin/false
5. Verify that /home/tftpdir exists:
# ll -d /home/tftpdir/

Configuring /etc/bootptab
The bootpd server process uses the /etc/bootptab file
to determine which IP address should be associated
with#each
address. This file can be manually edited.
vi MAC
/etc/bootptab
myprinter:\
hn:\
ht=ether:\
ha=080009a752c3:\
ip=128.1.1.4:\
sm=255.255.0.0:\
gw=128.1.0.1:\
dn=ca.hp.com:\

Configuring /etc/bootptab via hppi (1 of 2)
You can add entries to /etc/bootptab using any editor,
but for network printers it’s easier to use HP’s hppi utility.
1.
Enable BOOTP and TFTP
# setup_bootp
# setup_tftp –h
2.
Install the HP Network Printer Library product
# swlist HPNPL
3.
Add the printer’s hostname to DNS or /etc/hosts
# vi /etc/hosts
4.
Run the HP Printer Installer
# hppi -> JetDirect Configuration
-> Create printer configuration in BOOTP/TFTP database
