OpenBSD Change Hostname

To change the hostname on an OpenBSD system, you can follow these steps:

1. Edit the /etc/myname file and specify the new hostname. The /etc/myname file contains the hostname of the system, and changing the contents of this file will change the hostname.

For example, to change the hostname to newhostname, you can use the following command:

echo newhostname > /etc/myname

2. Restart the syslogd daemon to apply the changes. You can use the following command to restart the syslogd daemon:

/etc/rc.d/syslogd restart

3. Reboot the system to apply the changes. You can use the following command to reboot the system:

reboot

After the system has restarted, the new hostname will be in effect.

Note that changing the hostname may also require modifying other configuration files that use the hostname, such as /etc/hosts and /etc/ssh/ssh_host_rsa_key.pub.

For more information about changing the hostname on OpenBSD, you can refer to the OpenBSD documentation or search online for tutorials and examples.
