Server
DHCP is used for dynamic allocation of IP address services, when a network of more computers, we need to manually set the IP address for each client, subnet mask, DNS and gateway and other addresses, operation is very troublesome. With DHCP we can be a dedicated DHCP server

Let's do a simple experiment on Ros today, in a typical dozens of-person small company or a few people's home, if you come to how Ros do the most basic internet operation.Knowledge Points:
Ros as a DHCP Server for the intranet.
Ros as the client of PPPoE (the average person rarely uses ADSL access)
Ros makes a pat so that intranet users can surf the Internet.

During the DHCP learning process, we need to know about the DHCP server operations. This includes a lot of content. It can be seen that the application of the DHCP server is very important. This time, we will mainly explain the definition of the scope. To create a new scope,

Fixed-address IP is assigned to a client with a fixed address. Authritative rejects the request for an incorrect IP address. declarations (declaration) in the 2.

In the previous article, we explained the troubleshooting ideas of the DHCP service. I don't know if you already have a clear understanding of it? Here we will focus on the client issues.
Client troubleshooting:
DHCP faults mainly involve two aspects: client problems and server problems. First, we will introduce the troubleshooting methods on the client.
Step 1:
To configure the DHCP server dhcpd, edit the dhcpd. conf sample file from the server directory and install it as/etc/dhcpd. conf20. At the same time, you must create an empty lease database file named/var/db/dhcp. leases and run the touch Command. Make sure that dhcpd can be written...
