OpenBSD Change Hostname

Q. How do I change my hostname under OpenBSD operating system?

A. The hostname command displays the name of the current host. The superuser (root) can set the host name by editing a /etc/myname file. This is used at system boot time by netstart to initialize the hostname.

Task: OpenBSD Display hostname

Type the any one of the following command
# hostname
# cat /etc/myname
Output:

openbsd.nixcraft.in

Task: OpenBSD Chane Host Name

Simply login as root and type the following command:
# echo "new-hostname.domain.com" > /etc/myname
# echo "server.nixcraft.in" > /etc/myname
# echo 'unixbox' > /etc/myname
