You're probably going to have to tune that a bit, but this is
the approach I'm using to manage both server and switch
booting, and it works well.</div>

again!<br>
<br>
Since the 1.1 release i decided to try and migrate from
isc-dhcp. And there is a few things I have questions about.<br>
<br>
For years I have been using a python script to feed my
PowerDNS it's records using this:<br>
<br>
on commit {<br>
set ClientIP = binary-to-ascii(10, 8, ".",
leased-address);<br>
set ClientMac = binary-to-ascii(16, 8, ":",
substring(hardware, 1, 6));<br>
log(concat("Commit: IP: ", ClientIP, " Mac:
", ClientMac, "Hostname: ", option host-name));<br>
execute("/etc/pdns/dhcp-event"<wbr>,
"commit", ClientIP, ClientMac, option host-name);<br>
}<br>
<br>
Is it still possible to call and external script?<br>
<br>
At the same time I've been using a php file that loads the
designated boot menu for the booted mac-address:<br>
<br>
subnet 10.0.0.0 netmask 255.255.255.0 {<br>
[...]<br>
<br>
if not exists gpxe.bus-id {<br>
filename "undionly.kpxe";<br>
} else {<br>
filename "<a href="http://10.0.0.9/tftp/boot.php" rel="noreferrer" target="_blank">http://10.0.0.9/tftp/boot.php</a><wbr>";<br>
}<br>
[...]<br>
}<br>
<br>
I'm not sure I can still use this line of code?<br>
<br>
Thanks in advance!<br>
