We have 2 Dhcp server, dhcp3 service former debian, then changing<br class="">
of virtualizing server, I have to reinstall them on new esxi virtualizing servers,<br class="">
so did install debian 10 and isc dhcp server, copie dhcpd.conf config file and adapt it,<br class="">
verify it with dhcpd -t dhcpd.conf got not error,<br class="">
so start it and got error message:<br class="">
<br class="">
no subnet declaration for start (no ipv4 adresses)<br class="">
<br class="">
not configured to listen on any interfaces!<br class="">
<br class="">
I then checked /etc/default/isc-dhcp-server and /etc/network/interface files<br class="">
which looked ok.<br class="">
I had been advised to start with simpler dhcp.conf files to start and add bit by bit areas?<br class="">
But I always get the same error message whatever subnet declration I have inside my config file.<br class="">
<br class="">
I don?t understand what happens or what to do now? looks like what ever the dhcpd.conf file is, I get same error<br class="">
message, is there any other config file I don?t know about ? or anything missing ?<br class="">

Hi Charles,<br class="">
<br class="">
The broadcast address in the interfaces file doesn't match the subnet:<br class="">
<br class="">
broadcast 192.134.130.31<br class="">
<br class="">
should be<br class="">
<br class="">
broadcast 192.134.130.47<br class="">
<br class="">
and that might cause dhcpd to think the local ip address is not in the <br class="">
subnet.<br class="">
<br class="">
Second thing is that the ip address of the dhcpd server is in the <br class="">
defined range for dhcpd to hand out. The range should be specified as<br class="">
<br class="">
range 192.134.130.34 192.134.130.42;<br class="">
range 192.134.130.44 192.134.130.46;<br class="">
<br class="">

Hi!</div>
<div><br class="">
</div>
<div>thank you very much! that was it!</div>
<div><br class="">
</div>
<div>after many tries and changes may be the broadcast address of the interface fil finally ended wrong.</div>
<div>but I didn’t think about the server itself being in subnet…</div>
<div>I changed and tried and no more error message, but this one instead:</div>
<div>There’s already a DHCP server running.</div>
<div><br class="">
</div>
<div>I so changed the IP to the former server and stopped it, it was secondary…</div>
<div>Got same « There’s already a DHCP server running »</div>
<div>So did the same for primary server, and got always same message error There’s always a DHCP server running.</div>
<div>Both new server have now the former server Ip adresse, and former servers are stopped.</div>
<div>Well, so did go back, changing IP and stopping new servers and running former servers till tomorrow.</div>
<div><br class="">
</div>
<div>Is there timing to stop and replace, to avoid this and let new server replace formers ?</div>
