Solution to ping Baidu in Linux

Solution to ping Baidu in Linux

I encountered a problem when I learned about DNS today. My virtual machine can ping the IP address but cannot ping www.baidu.com www.qq.com or other domain names. First, the following error occurs:

After several hours, I finally found a solution.

1. Check whether the virtual machine can ping the Internet. You can ping the gateway.

ping 172.17.0.1

[Plain] view plaincopy

2. Make sure that the gateway is configured

[Plain] view plaincopy

Vim/etc/sysconfig/network-scripts/ifcfg-eth1
[Plain] view plaincopy

GATEWAY = 172.17.0.1

DNS1 = 172.17.0.1

After the modification, You need to restart the network service. Centos6:

Service network restart

3. Make sure there are available domain name servers

Cat/etc/resolv. conf

If not, edit one by yourself.

[Plain] view plaincopy

Vim/etc/resolv. conf

Nameserver 172.17.0.1

Nameserver 114.114.114.114

In this case, there is no problem.

But I still encountered a problem.

It should still be a network problem. I restarted the network service, but it still doesn't work.

So I checked the route table and found that a default route record is missing.

Add a route record.

Failed to add

We had to clear the path with records

Restart the network service, add the default route, and then parse the address.
