Used to be "root@localhost". The system is CentOS Release 6.4 in a VMware virtual machine. Yesterday I did some test of the user and group commands. And I noticed the tty1 login prompt changed to be "bogon login". And then the pts prompt changed after that. My question is how to change it back?
Since the prompt change was not due to my deliberate modification to variable PS1, I suspect that there must be some reason for this. I want to dig it out and thus prevent future auto change to the "bogon" name again. Also, I want to know the what the word bogon stands for.
As I indicated in the comment, this is not the first time that happened to my Linux virtual machine. Yes, the virtual machine is connected to a DHCP wifi router.
