In Linux, IP and MAC are bound to the Internet-Linux general technology-Linux technology and application information. The following is a detailed description. Because our school data center uses IP and MAC binding to access the Internet, each computer has a fixed IP address and MAC address, and I tried many ways to access the Internet. I don't think there is no way to access the Internet, instead, they do not know how to operate on the basis of others' methods. Originally installed UBUNTU, And now installed a REDHAT. The interface is more inclined to WINDOWS. After the interface is installed, I did not successfully configure the internet. Give up. Today's whimsy, REDHAT is much easier to operate than UBUNTU, and it should be easier to configure the internet, so I made up my mind to configure it well. Haha, I finally succeeded.
First, configure the IP and MAC in the XP system to enable it to access the Internet. Then go to the LINUX system. System-management-network, enter your password. Go in. In the device, set the IP address and Its subnet mask, default gateway, DNS, MAC., and then activate. Make its location active. Restart the network: in the terminal: Super User: #/etc/init. d/network restart. Theoretically OK. You can still be unable to access the Internet. PING your own machine and the machine in the LAN can be connected. It's really depressing. As a result, we can check in #/sbin/isconfig eth0 under the terminal Super User. HWaddr hasn't changed yet, and TMD is ready to restart the network again. You can just press/etc/init. d/network and press ENTER accidentally. Haha, I'm lucky.
The following five options are available: start, stop, restart, reload, and status. So I tried/etc/init. d/network reload at will. Haha succeeded. Later, I found in Kingsoft's word Overlord that reload means reload.
I tried restarting. After the restart, it was a one-time task. One-time deployment. Who makes me a cainiao. So pay attention to this use is also satisfied. The method for setting one time is as follows:
You must first disable the NIC device. Otherwise, the system is reported to be busy and cannot be changed.
Command:
#/Sbin/ifconfig eth0 down
Modify the MAC address. This step is simpler than that in Windows.
Command:
#/Sbin/ifconfig eth0 hw ether 00: AA: BB: CC: DD: EE
Enable Nic again
#/Sbin/ifconfig eht0 up
The MAC address of the NIC is changed.
Restart the network (reload)
#/Etc/init. d/network restart or reload
