and then copy the following code into: @echo off REM ETH//eth is the name of the network adapter, which can be queried in a networking connection, such as "local link" Set eth= "Wireless network Connection" REM IP//ip for the IP you want to change Set ip=192.168.1.8 REM GW//GW for gateway address Set gw=192.168.1.1 REM netmasks//netmasks for subnet masks

Nowadays, with more and more users of the Win7 system using laptops, laptops have the incomparable advantage of desktop, which is to carry conveniently. Users can use the notebook computer in different places, but because of the system IP address setting reason, the user is unable to connect the network when using the notebook computer, but often changes the IP to be very troublesome. So what's the best way to solve this problem? In fact, we can quickly change the IP through batch files, the fol

For example:(1) Configure the IP address of the eth0 and activate the device at the same time. 　　#ifconfig eth0 192.168.1.10 netmask 255.255.255.0 up(2) Configure the IP address of the eth0 alias device eth0:1 and add the route. 　　#ifconfig eth0 192.168.1.3　　#route add–host 192.168.1.3 Dev eth0:1(3) Activate the device. 　　#ifconfig eth0 up(4) Disable the device. 　　#ifconfig eth0 Down(5) Vie

Finally, we save these commands as a bat file (setip192168423.bat): Copy Code code as follows: @echo off Rem ETH is the name of the network adapter, which can be queried in a networking connection, such as "Local link" Set//eth "Local link" eth= R>rem IP//ip for the IP set ip=192.168.4.23 rem GW//GW you want to change for the gateway address Set

The network configuration command under Linux is ifconfig similar to the ipconfig in the Windows command line. You can use the Ifconfig command to configure and view the configuration of network interfaces. For example: (1) Configure the IP address of the eth0 while activating the device. #ifconfig eth0 192.168.1.10 netmask 255.255.255.0 up (2) configures the IP address of eth0 alias device Eth0:1 and adds a route. #ifconfig eth0 192.168.1.3 #route add–host 192.168.1.3 Dev eth0:1 (3) activates t

In order for the device to access another subnet, you need to increase the routing to the sub-network in the device, here are some information. The basic operations are as follows:In general, to be able to access other subnets to set up the route, for example, your host is in 192.168.10.0/24, and you want to access the 192.168.20.0/24 network host, of course, you know a gateway IP, For example 192.168.10.1 (must be on the same subnet as your host), you can configure the route as such.Add routeRo

We have learned from the article ARP working principles that the host will save and update the local ARP cache table in two cases,1. When receiving the "ARP broadcast-request" Packet2. When an "ARP non-broadcast-reply" packet is received We can see that the ARP Protocol has no authentication mechanism, and any host in the LAN can forge ARP packets at will. The ARP protocol design is inherently flawed. Assume that there are three hosts (GW refers t

(which cannot ping the company network ), but Linux cannot ping the XP system machine. This problem has been solved, and now the XP system can be connected to the company's network segment 192.168.4.0, but also to the Internet The solution is static routing settings + NAT translation of iptables, which enables the XP system (IP 111.111.112.112) to access the Internet through the IP address eth1 (IP 192.168.4.129) and implement Nat translation.
