Not to be mentioned, direct two examples:
1, Automatic modification network address:
Copy Code code as follows:
@echo off
netsh interface ip set address name= "Local Area Connection" static 192.168.1.55 255.255.255.0 192.168.1.1 Auto >nul
netsh interface ip add DNS "Local Area Connection" 202.98.96.68 index=1 >nul
netsh interface

Modify the IP address First check your host card number and name, related information under/etc/sysconfig/network-scripts/. You can see that I have 2
When there is a problem with our network, we may have to solve it by tracking the IP address. In the WinXP system we may have access to a number of IP addresses, how can we find the IP address that is not used? Today, we will share a solution to the small series.

Article Title: how to configure multiple IP addresses for a network card in Linux. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source.
We know that in Linux, NICs are called eth0, eth1, eth2 ......, All Nic configuration files are

Two NICs may be disconnected in the same network segment, but the IP addresses that ping the NIC can still be pinged. The two IP addresses are directed to the same MAC address.

Three methods for configuring network IP addresses in RHEL7.0GuideThe NIC naming method in RHEL7 is changed from eth0, 1, 2 to enoXXXXX. En represents enthernet (Ethernet), o represents onboard (built-in), and a string of numbers is automatically generated by an index number of the motherboard to ensure its uniqueness. Compared with the original naming method, th

Recently, we need to use the Linux iptablesNAT function to map ports, but the interface machine only has one Nic. To achieve both Intranet access and Internet access, we need to use the methods described below: 1. Assume that the Intranet IP address is address192.168.100.6netmask?255.255.0gateway192.
We recently used the Linux iptables NAT Function to map ports,However, the interface machine has only one Nic, which must be able to access both the Int
