Chapter 1. Getting Started with RedBoot
Enable BOOTP/DHCP server on Red Hat Linux
First, ensure that you have the proper package, dhcp (not dhcpd ) installed. The DHCP server provides Dynamic
Host Configuration, that is, IP address and other data to hosts on a network. It does this in different ways. Next,
there can be a fixed relationship between a certain node and the data, based on that node’s unique Ethernet Station
Address (ESA, sometimes called a MAC address). The other possibility is simply to assign addresses that are free.
The sample DHCP configuration file shown does both. Refer to the DHCP documentation for more details.
Example 1-1. Sample DHCP configuration file
--------------- /etc/dhcpd.conf -----------------------------
default-lease-time 600;
max-lease-time 7200;
option subnet-mask 255.255.255.0;
option broadcast-address 192.168.1.255;
option domain-name-servers 198.41.0.4, 128.9.0.107;
option domain-name “bogus.com”;
allow bootp;
shared-network BOGUS {
subnet 192.168.1.0 netmask 255.255.255.0 {
option routers 192.168.1.101;
range 192.168.1.1 192.168.1.254;
}
}
host mbx {
hardware ethernet 08:00:3E:28:79:B8;
fixed-address 192.168.1.20;
filename “/tftpboot/192.168.1.21/zImage”;
default-lease-time -1;
server-name “srvr.bugus.com”;
server-identifier 192.168.1.101;
option host-name “mbx”;
}
Once the DHCP package has been installed and the configuration file set up, type:
# service dhcpd start
Enable DNS server on Red Hat Linux
First, ensure that you have the proper RPM package, caching-nameserver installed. Then change the configura-
tion (in /etc/named.conf ) so that the forwarders point to the primary nameservers for your machine, normally
using the nameservers listed in /etc/resolv.conf .
Example 1-2. Sample /etc/named.conf for Red Hat Linux 7.x
--------------- /etc/named.conf -----------------------------
// generated by named-bootconf.pl
options {
directory "/var/named";
