Solve the problem of hostname changing Bogon under Linux

Wake up in the morning find the Linux hostname changed to Bogon

Bogon refers to addresses that should not appear in the Internet routing table.
These addresses should include:
1, private address such as 10,172.16-32,192.168 .....
2. Address not officially assigned

After Google found a way to change the name

One: Using the hostname command
[Email protected] ~]# hostname yourname
This only changes the host name temporarily.
Two: Modify the Linux host configuration files/etc/sysconfig/network and/etc/hosts
1. Modify the host name inside the/etc/sysconfig/network.
# vi/etc/sysconfig/network
Networking=yes
Hostname=yourname//Modify HOSTNAME in this
gateway=192.168.1.1//Your IP address
2. Modify the name inside the/etc/hosts
# vi/etc/hosts
127.0.0.1 localhost.localdomain localhost
192.168.1.121 yourname//In this change hostname//Your IP address
Sometimes this is the only line.
127.0.0.1 yourname localhost.localdomain localhost
3. Make the name of the change effective without restarting the machine
# hostname Yourname
# su
