Install DHCP Server on Ubuntu

DHCP Server will greatly assist us in providing computers ip address on the LAN, because the DHCP server will provide ip address automatically, and I install the DHCP Server on the server version of ubuntu 8:10.

OK, straight to the practice !

The first step is to take the package and install dhcp3-server :

root@server:/# aptitude update && aptitude install dhcp3-server

Once installed dhcp3-server, you must edit the file / etc/dhcp3/dhcpd.conf. For example, add the following line :

root@server:/# vim /etc/dhcp3/dhcpd.conf

subnet 10.14.10.0 netmask 255.255.255.0 {
range 10.14.10.100 10.14.10.150;
option routers 10.14.10.1;
option domain-name-servers 10.14.10.1;
}

Description:

Adding the above lines would configure the DHCP server to serve requests from the network LAN IP 10.14.10.0 and each computer will get an IP from IP 10.14.10.100 to 10.14.10.150, a default gateway configuration 10.14.10.1, and 10.14.10.1 DNS servers.

And if we want to give specific IP for a particular computer, we can add the following line in the configuration file /etc/dhcp3/dhcpd.conf, the following steps :

root@server:/# vim /etc/dhcp3/dhcpd.conf

host server {
hardware ethernet 08:OI:89:0e:86:21;
fixed-address 10.14.10.100;
}

host server1 {
hardware ethernet 00:24:8A:0e:86:C5;
fixed-address 10.14.10.101;
}

Description:

Above configuration will cause the dhcp server to give IP 10.14.10.100 to the computer with MAC address 08: OI: 89:0 e: 86:21 and give Ip address 10.14.10.101 to the computer with MAC address 00:24:8A:0e:86:C5
