This article mainly explains "Suse Linux DHCP server configuration method", the explanation content in the article is simple and clear, easy to learn and understand, please follow the idea of Xiaobian slowly in-depth, together to study and learn "Suse Linux DHCP server configuration method"!

A lot of Suse Linux DHCP server configuration, and this article explains the DHCP server configuration in detail, here and share with you, I hope to help you.

There are two types of statements in configuration files:

Parameters indicate how to perform the task, whether to perform the task, or which network configuration options to send to the customer.

Declarations describe the layout of the network; describe customers; provide addresses for customers; or apply a set of parameters to a set of declarations.

Some parameters must begin with the option keyword, and they are also called options. Options configure optional options for DHCP; parameters configure values that are required or control DHCP server behavior.

Parameters (including options) declared before the part with braces ({ }) are usually treated as global parameters. Global parameters apply to all sections below them.

Note that each parameter is separated by semicolons.

configure the DHCP server

You can configure DHCP servers using the configuration file/etc/dhcpd.conf.

DHCP also uses the/var/lib/dhcp/dhcpd.leases file to store the customer lease database. Please refer to Section 18.2.2 for details.

profile

The *** step in configuring a DHCP server is to create a configuration file that stores customer network information. Global options can be declared for all customers and optional options can be declared for each customer system.

The profile can be formatted simply with any additional tabs or blank lines. Keywords are case-sensitive, and lines that begin with a pound sign (#) are comments.

Two DNS update schemes are currently implemented

Special DNS update mode and transitional DHCP-DNS interactive sketch update mode. If these two modes are accepted as part of the IETF standards process, a third mode, the standard DNS update method, will emerge. DHCP servers must be configured to use one of these two current schemes. Version 3.0b2pl11 and earlier used a special pattern; however, this pattern is obsolete. If you want to keep the same behavior, add the following line to the beginning of the profile:

ddns-update-style ad-hoc;

To use the recommended pattern, add the following line to the beginning of the configuration file:

ddns-update-style interim;

This way you can easily configure the Suse Linux DHCP server.

Thank you for reading, the above is the "Suse Linux DHCP server configuration method" content, after learning this article, I believe we have a deeper understanding of the Suse Linux DHCP server configuration method, the specific use of the situation also needs to be verified. Here is, Xiaobian will push more articles related to knowledge points for everyone, welcome to pay attention!
