Configuring a Relay Agent
Chapter 10916
To configure the relay agent, follow these steps:
NOTE You must make the changes on the relay system manually (that is,
without using SAM).
Later, when you use SAM to configure a gateway client, use the IP
address of the relay system in the “Default Route” field of the “Define
Clients” screen.
Step 1. In the file /etc/inetd.conf, add the following line if it does not already
exist:
bootps dgram udp wait root /usr/lbin/bootpd bootpd
Step 2. In the file /etc/bootptab, add the following information for each client
that may be booted across the gateway served by this relay system. (See
bootpd (1M) and comments in the file /etc/bootptab for further
information.)
# The following is a client that boots from server :
client's_host_name :\
ht=ethernet:\
ha= client's_hardware_address :\
bp= server's_IP_address :\
hp=1
The hop count, hp, must be 1.
For example, using the information displayed by the ping command
above to configure client wendy to boot from server peter across a
gateway using relay system tinkrbel, install the following entry on
tinkrbel:
# client 'wendy' (ha) boots from server 'peter' (bp)
wendy:\
ht=ethernet:\
bp=153.13.115.149:\
ha=08009935c990:\
bp=153.13.115.149:\
hp=1
Step 3. In the /etc/rc.config.d/netdaemons file, set the value of
START_RBOOTD to 1 to ensure that the rbootd daemon starts at boot time:
