Ah ok.  Thanks.

I’ve just tried this and it kills the kea daemon completely.  Ubuntu 16.04, kea 1.0.0 for the apt repo.

Using “service kea-dhcp4-server start” to start the daemon.

root at az01-dhcp-02:/# ps -ef | grep kea
root     14798     1  0 16:39 ?        00:00:00 /usr/sbin/kea-dhcp4 -c /etc/kea/kea-dhcp4.conf
root     14994 14631  0 16:47 pts/1    00:00:00 grep --color=auto kea

root at az01-dhcp-02:/# kill -SIGHUP 14798

root at az01-dhcp-02:/# ps -ef | grep kea
root     14999 14631  0 16:47 pts/1    00:00:00 grep --color=auto kea

root at az01-dhcp-02:/# ps -ef | grep kea
root     15001 14631  0 16:47 pts/1    00:00:00 grep --color=auto kea

root at az01-dhcp-02:/# ps -ef | grep kea
root     15003 14631  0 16:47 pts/1    00:00:00 grep --color=auto kea

root at az01-dhcp-02:/# ps -ef | grep kea
root     15005 14631  0 16:47 pts/1    00:00:00 grep --color=auto kea


Hmmm.  There is no keactrl with the package either, may have to hunt that down in manually install it.

    Sending SIGHUP instructs the running server to reload the configuration
    file.  Using "service" to restart would actually tell the OS to stop the
    current instance of the server and then restart it.
