In OpenBSD, you can reload, restart, or stop the dhcpd daemon by sending a signal to the dhcpd process.
To reload the dhcpd daemon, you can use the SIGHUP signal. To do this, you can use the kill command followed by the -HUP option and the process ID of the dhcpd process.
For example, to reload the dhcpd daemon with process ID 12345, you can use the following command:
kill -HUP 12345
To restart the dhcpd daemon, you can use the SIGINT signal. To do this, you can use the kill command followed by the -INT option and the process ID of the dhcpd process.
For example, to restart the dhcpd daemon with process ID 12345, you can use the following command:
kill -INT 12345
To stop the dhcpd daemon, you can use the SIGTERM signal. To do this, you can use the kill command followed by the -TERM option and the process ID of the dhcpd process.
For example, to stop the dhcpd daemon with process ID 12345, you can use the following command:
kill -TERM 12345
Keep in mind that you may need to run the kill command as the root user or with superuser privileges in order to send a signal to the dhcpd process.
You can also use the rcctl command to manage the dhcpd daemon. Consult the OpenBSD documentation for more information on the rcctl command and how to use it to manage system services.
Keep in mind that these are just general steps, and your specific configuration may vary depending on your system's setup. Consult the OpenBSD documentation for more detailed information.
