<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Hi Eugène<br>
<br>
Are the dhcp server and clients physical systems or virtual? What<br>
operating system are the server and clients?<br>
<br>
What version is dhcpd? This will be in the startup message in the logs, of<br>
use dhcpd --version<br>
<br>
What happens if you comment out one of the host statements so that the<br>
client gets a dynamic lease?<br>
<br>
