Ping www.baidu.com

Ping does not pass

Ping Baidu's ip:220.181.111.188 but can ping through

This proves to be a problem with DNS

Baidu after check to set the DNS need to run the command: vi/etc/resolv.conf

Add to:

NameServer 192.168.0.1

NameServer 192.168.0.1

However, after running the vi/etc/resolv.conf prompt:

# Generated by NetworkManager
Search an

# No nameservers found; Try putting DNS servers into your
# ifcfg files in/etc/sysconfig/network-scripts like so:
#
# dns1=xxx.xxx.xxx.xxx
# dns2=xxx.xxx.xxx.xxx
# domain=lab.foo.com Bar.foo.com

So run Vi/etc/sysconfig/network-scripts/ifcfg-eth0

Add to

# dns1=192.168.0.1
# dns2=192.168.0.1
# domain=lab.foo.com Bar.foo.com

Running Service Network restart

Find out or ping not pass

Run vi/etc/resolv.conf Discovery added nameserver missing

Find a solution after a network search:

1. #Remove Network Manager from startup service

Chkconfig Networkmanagermangager off

2. #Add Default Net Manager

Chconfig Network on

3. Stop NetworkManager First

Service NetworkManager Stop

4. #and then start Default Manager

Service Network start

5. #restart Network

Service Network restart

Reconfigure the DNS configuration file to restart the network
