Chapter 7 Unix Ethernet Interface Configuration
102
Using BOOTP
BOOTP allows you to dynamically assign an IP address to the Ethernet
Interface upon bootup. In addition, the BOOTP server can provide
additional details like a default router/gateway address. To configure the
Ethernet Interface with its TCP/IP settings using BOOTP:
1. On your BOOTP server, make an entry in the /etc/bootptab file for the
Ethernet Interface.
Syntax:
EthernetInterfaceIPname
:\
:sm=
netmask
:\
:hd=
homedirectory
:\
:bf=null:\
:gw=
defaultgateway
:\
:ht=ethernet:\
:ha=
ethernetaddress
:\
:ip=
ipaddress
:\
:ts=
timeserver
:\
:to=
timezone
:
Example:
spike:\
:sm=255.255.255.0:\
:hd=/usr/null:\
:bf=null:\
:gw=192.75.11.1:\
:ht=ethernet:\
:ha=008072070060:\
:ip=192.75.11.9:\
:ts=192.75.11.7:\
:to=25200:
2. Turn the Ethernet Interface on so that it immediately sends out a
BOOTP request. Wait one minute to allow the IP address assignment
process to complete. You should see the STAT LED, on the Ethernet
Interface, slow down indicating it knows about an IP address to use.
3. Try to “
ping” the Ethernet Interface IP address from a network
station to see if it can be seen on your network.
