4Workaround for hostname changed to Bogon

Modify configuration files for Linux hosts/etc/sysconfig/network and/etc/hosts
1). Modify the host name inside the/etc/sysconfig/network.

[[email protected] ~]#  VI/ETC/SYSCONFIG/NETWORKNETWORKING=YESHOSTNAME=XG                //modify hostname for XG in this

2). Modify the name inside the/etc/hosts

[Email protected] ~]#  vi/etc/hosts127.0.0.1              xg

3). Do not need to restart the host, and finally execute under the terminal:

[[email protected] ~]# hostname xg     //XG for modified Hostname[[email protected] ~]#

This method is not useful after restarting
