DHCP Server Configuration Part-1

DHCP Server Configuration

Step-1:  To check dhcp  rpm package is installed or not by following this command:

                       

(if installed then it will show dhcp packages)

[root@dhcp ~]# rpm -qa | grep –i dhcp*    or

[root@dhcp ~]#  rpm –qa dhcp*

dhcp-3.0.5-21.el5

dhcp-devel-3.0.5-21.el5

libdhcp-devel-1.20-10.el5

dhcpv6-client-1.0.10-17.el5

libdhcp-1.20-10.el5

libdhcp4client-3.0.5-21.el5

libdhcp6client-devel-1.0.10-17.el5

libdhcp4client-devel-3.0.5-21.el5

dhclient-3.0.5-21.el5

           If not installed, then installed the packages using  Yum command:

[root@dhcp ~]# Yum Install dhcp* lib*

Step-2: Check and Configure the Network Card:

[root@dhcp ~]# vi /etc/sysconfig/network-scripts/ifcfg-eth0

(Original File):

#Broadcom Corporation Net link BCM57875 Gigabyte Ethernet PCI Express

DEVICE=eth0
BOOTPROTO=dhcp
HWADDR=00:0C:29: EB: B2: CA
ONBOOT=yes

(Modified File):

#Broadcom Corporation Net link BCM57875 Gigabyte Ethernet PCI Express

DEVICE=eth0

BOOTPROTO=static

HWADDR=00:0C:29: EB: B2: CA

ONBOOT=yes

TYPE=Ethernet

PEERDNS=no

USERCTL=no

IPV6INIT=no

IPADDR=210.207.201.4

NETMASK=255.255.255.0

NETWORK=210.207.201.0

BROADCAST=210.207.201.255

Press Esc → Shift + : → x! → Enter (For Save and Exit the Vi Editor).

After changing you have to reload/restart the NIC(eth0) card by following command:

[root@dhcp ~]# ifdown eth0

[root@dhcp ~]# ifup eth0

[root@dhcp ~]# service network restart
