REDHAT5 virtual machines in VMware cannot connect to the network

REDHAT5 virtual machines in VMware cannot connect to network problems

Environment: Vmware10,radhat Enterprise 5.8, the virtual machine network uses the bridge connection way.

Problem: REHL5 in virtual machine cannot connect to network

Unable to access network: Ping baidu.com

Return: Ping:unknown host www.baidu.com

Reason: Unable to obtain IP dynamically:

[[email protected] ~]# ifconfig:eth0 IP display is IPv6

[Email protected] ~]# service network restart

Return: dertermining IP information for eth0....failed

Workaround:

1. Add the following script to the/etc/sysconfig/network-scripts/ifcfg-eth0:

Check_link_down () {

return 1;

}

Take the files in my virtual machine as an example:

[Email protected] ~]# Vim/etc/sysconfig/network-scripts/ifcfg-eth0

# advanced Micro Devices [AMD] 79c970 [PCnet32 LANCE]

Device=eth0

Bootproto=dhcp

Hwaddr=00:0c:29:93:c0:95

Onboot=yes

Check_link_down () {

return 1;

}

#保存退出

2. Restart Eth0:

[Email protected] ~]# Ifdown eth0

[Email protected] ~]# ifup eth0

3, test (now can be connected to the normal network)

[[email protected] ~]# Ping baidu.com

A bit of confusion is: After the deletion of the previously added script can also be normal access to the network ...
