As a DHCP server, it can be configured in many systems and methods. We implement it in a virtual machine environment. Generally, when a virtual machine is opened, it will slow down. We only use one 2003 Server for customer service machine verification, during verification, you only need to set the 2003 Nic channel. In this experiment, the Red Hat Enterprise Editi

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...
To configure the
One principle of self-building a server is to first let it work.
Let the DHCP server go to Ubuntu,
I wrote this article mainly because there is a small one, but it is not mentioned on the Internet as a key step. Looking at the instructions on the Internet, of course I chose a dhcp3-sever package.

Build a route, DNS, and DHCP server in a simulated Public Network EnvironmentToday, we will continue to add a server in the test environment to simulate a vro in the public network environment. This server can simulate common vro functions in the public network as much as possible, it includes three functions: routing,
Most of the time, Linux is a configuration platform we need. We implement it in a virtual machine environment. Generally, when a virtual machine is opened, it will slow down. We only use one 2003 Server for customer service machine verification, during verification, you only need to set the 2003 Nic channel. In this experiment, the Red Hat Enterprise Edition 4 is used. The following describes how to implement the

Sales of the LAN scale is increasing, the number of clients increased sharply, sales department of the network management wax gourd to avoid manually assigning IP addresses to clients, want to use DHCP server to achieve dynamic allocation of IP addresses. In this way, the IP address of the client is often changed, and the day-to-day maintenance work is caused by difficulties.

DHCP Server Configuration:
Dynamic Host Configuration Protocol (DHCP) is a LAN network protocol that uses UDP for two purposes: to automatically assign IP addresses to internal network or network service providers, it provides users or internal network administrators with central management measures for all computers.
