VM under redhat9.0 can't surf the internet

recently I am learning Linux, after installing red Hat Linux9, but can not be on the net, to check the data also have to switch to the virtual machine up, special consumption of time. Fortunately, not crazy! First, test your Linux to see if it is such a problem, enter ping www. 163. com, the following prompt appears, then the problem is right. The main reason: because the virtual network card created by VMware Workstation is too new, and the relative "Red Hat linux9" itself comes with the NIC driver, on this "new network card" will not work properly. I chose a NAT connection , but some people can use bridging, I have not tried.

Second: Enter the setup  command, the interface that appears:

Select the network configuration here and click the Run Tool button to display the interface:

This is, click the SPACEBAR, select the use dynamic IP configuration, in square brackets or "*" to indicate that it is selected, then click the OK button, exit the interface, and then click Quit, exit the total interface, return to the Terminal interface: Input vi/ect/in the terminal interface sysconfig/network-scripts/ifcfg-eth0,:

This interface appears, indicating the current IP device configuration parameters.

Add the following information at the end of the file: then save the exit. (Wq)

At the same time in the terminal input vi/etc/sysconfig/networking/ifcfg-eth0, here the (ifcfg-eth0 file is newly created, so the content is empty), enter the following content in the file: and save the exit.

At this point, in the terminal input ifdown eth0, close eth0, and then in the input ifup eth0 command, this will appear the IP information that is deciding eth0 ... Complete. Below you enter to try the ping command, the miracle finally appeared.

OK, you should be able to do it now, not to try it!
