DHCP Server

Set DHCP ( Dynamic Host Configuration Protocol ) Server in Linux Box.

Lets first install DHCP package in
1. yum -y install dhcp

Now that you have installed the dhcp package in your linux box, lets start configuring it.

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

3. vim /etc/dhcpd.conf

#line 4: specify your network and subnet

subnet 192.168.0.0 netmask 255.255.255.0 {

# line 7 : specify default gateway
option routers192.168.0.1;

# line 8: specify subnetmask
option subnet-mask255.255.255.0;

# line 10: specify NIS domain name if you are using.
# make it comment if you don not use.
option nis-domain "bhutanhorizon.com";

# line 11: specify domain name
option domain-name "bhutanhorizon.com";

# line 12: specify IP address of DNS
option domain-name-servers 192.168.0.10;

# line 14: make it comment
# option time-offset-18000;

# line 21: specify the range of IP addresses for clients
range dynamic-bootp 192.168.0.128 192.168.0.254;

# line 22: default's terms of lease
default-lease-time 21600;

# line 23: maximun terms of lease
max-lease-time 43200;

# line 26: make following lines comment
#host ns {
#next-server marvin.redhat.com;
#hardware ethernet 12:34:56:78:AB:CD;
#fixed-address 207.175.42.254;
#}

4. Now you have configured the DHCP server. Now you need to start the service named dhcpd

service dhcpd start

5. Now you have to make the service start when ever the linux box starts/reboot

chkconfig dhcpd on


That's it! you see how easy it is to configure DHCP in linux box compare to Windows Server OS.
