DHCP :


Dynamic Host Configuration Protocol (DHCP) is a client/server protocol that automatically provides an Internet Protocol (IP) host with its IP address and other related configuration information such as the subnet mask and default gateway.

 Simply in this we can host remote pc's as per our requirements.

 And in this we can allocate ip address then it will set automatically within range.

 Just like to which pc(mac address of perticular pc) we wanna to create our client or which we want to restrict this will be possible through this dhcp. 

Steps for  DHCP are as follows :

(note : only for fedora 19)

1.first of all open terminal->

service iptables stop

 service firewalld stop
 yum install dhcp

 systemctl start dhcpd.service

 systemctl enable dhcpd.service

 service dhcpd status

o/p:

Redirecting to /bin/systemctl status  dhcpd.service
