dhcpd

Nainštalujeme si dhcp daemona:

#yum install dhcp

Skopírujeme defaultny config:

#cp /usr/share/doc/dhcp*/dhcpd.conf.sample /etc/dhcpd.conf

Config je úplne jednoduchý a okomentovaný takže s nasatvením by nemal byť problem.

#cat /etc/dhcpd.config
ddns-update-style interim;
ignore client-updates;

subnet 192.168.0.0 netmask 255.255.255.0 {

# — default gateway
option routers 192.168.0.1;
option subnet-mask 255.255.255.0;

option nis-domain “domain.org”;
option domain-name “domain.org”;
option domain-name-servers 192.168.1.1;
