Next I will be uploading the configuration of DHCP Server Debian 6, this is the 2nd stage on my tutorial.Before that I will explain in advance about the DHCP Server.
What Is A DHCP Server?
DHCP (Dynamic Host Configuration Protocol) is a service that automatically provides IP numbers to computers that request it. A computer that delivers the IP number is referred to as DHCP servers, while the computer that requests the IP number is referred to as a DHCP Client. Thus Administrators no longer need to have to give the IP number manually at the time of the TCP/IP configuration, but it is enough to give reference to the DHCP Server.
At a time when both the DHCP client is turned on, then the computer doing the request to the DHCP Server to get IP numbers. DHCP replied by giving the IP number that exists in the DHCP database. After the DHCP Server provides IP numbers, then server lend (lease) IP number to DHCP-Client and write off the IP number from the list of the pool. IP number is given along with the subnet mask and default gateway. If there are no more IP numbers that can be given, then the client can not initialize the TCP/IP, by itself can't connect on the network.
After a certain time period, then the DHCP Client usage is stated over and not renew the client request is returned, then the IP number is returned to the DHCP Server, and the server can give the IP number to Clients in need. Long period can be specified in minutes, hours, month or forever. Time period called leased period.

The Workings Of The DHCP Server
DHCP uses a 4 stage process to provide a configuration of the IP number. (If the Client has more than one NIC and need no more than one IP then the DHCP process is executed for each adapter are singly).
DHCP uses a 4 stage process to provide a configuration of the IP number. (If the Client has more than one NIC and need no more than one IP then the DHCP process is executed for each adapter are singly).
- Least IP Request The Client asks for the IP number to the server (Broadcast looking for a DHCP server).
- Least IP Offer DHCP server (can be one or more of the servers if there are indeed two or more DHCP servers) that have a number of IP, provide a quote to the client such.
- IP Lease Selection The Client chooses the first DHCP Server offer received and return to broadcast with a message approving the loan to the DHCP Server
- IP Lease Acknowledge DHCP Server a win gives the answer to the message in the form of confirmation of IP numbers and other information to the Client with an ACKnowledgment. Then the client performs initialization with binding (binding) that IP number and client can work on the network.While the DHCP Server to another attractive his offer again.
- Facilitate in the transfer of data to another PC client or server PC. DHCP provides IP addresses dynamically and other configurations.
- DHCP allows a client to use the IP address that can be used by client not the other.
- DHCP allows a client to use one IP address for a period of time from the server.
- Save energy and time in administering IP.
- Prevent the occurrence of an IP conflict.
- Shortage Of DHCP Server All the granting of IP depends on the server, then from it if the server dies then will disconnect all computers and not connected to each other.
