Teach you how to complete Linux Network Address Configuration

If you want to know about Linux, learn about Linux. This article explains the Linux Network Address Configuration for you. I hope you can understand the Linux Network Address Configuration. Let's talk about this in detail.

1. Disable and enable the network port:

Enable port 81:
Iptables-I input-I eth0-p tcp -- dport 81-j ACCEPT
Iptables-I OUTPUT-o eth0-p tcp -- sport 81-j ACCEPT

Close port 81:
Iptables-I input-I eth0-p tcp -- dport 81-j DROP
Iptables-I OUTPUT-o eth0-p tcp -- sport 81-j DROP

2. Disable and enable physical ports
UP: ifconfig eth0 up
DOWN: ifconfig eth0 down
Or
/Sbin/ifup eth0
/Sbin/ifdown eth0
/Sbin/ifup | ifdown is a symbolic link to/etc/sysconfig/network-scripts/ifup | down

3. Configure the network address

A. ifconfig eth0 x. x netmask x. x broadcast x.

B. Configure through the configuration file
/Etc/sysconfig/network-scripts/file for configuring ifcfg-xx
Such as: ifcfg-eth0
If you want to configure multiple addresses on a network card, the configuration file is ifcfg-eth0: 1, ifcfg-eth0: 2, etc.

C. restart the network service,/etc/init. d/network restart or service network restart

In this way, you can easily complete the Linux Network Address Configuration.
