voici le log

Aug 27 08:57:09 SVR511 dhcpd: DHCPDISCOVER from 00:03:81:ee:e7:8a via eth1
Aug 27 08:57:10 SVR511 dhcpd: DHCPOFFER on 192.168.22.30 to 00:03:81:ee:e7:8a (MMMPUNEEETUA) via eth1
Aug 27 08:57:10 SVR511 dhcpd: DHCPREQUEST for 192.168.22.30 (192.168.22.2) from 00:03:81:ee:e7:8a (MMMPUNEEETUA) via eth1

mais cette adresse ip est configuré dans le serveur dhcp et le pc est fonctionnel sur l'adresse ip en question. Donc après le branchement de l'autre appareil, ca me donne un conflit d'adresse ip sur le réseau. voici l'exemple de la config.

host marcelb {
        hardware ethernet 00:1c:c0:71:bc:4f;
        fixed-address 192.168.22.30;
        }

dans la version 8.04 dhcp3-server : version 3.0.6.dfsg-1ubuntu9.1 , je n'avais pas ce genre de trouble .

merci

Here is the log:

Aug 27 08:57:09 SVR511 dhcpd: DHCPDISCOVER from 00:03:81:ee:e7:8a via eth1
Aug 27 08:57:10 SVR511 dhcpd: DHCPOFFER on 192.168.22.30 to 00:03:81:ee:e7:8a (MMMPUNEEETUA) via eth1
Aug 27 08:57:10 SVR511 dhcpd: DHCPREQUEST for 192.168.22.30 (192.168.22.2) from 00:03:81:ee:e7:8a (MMMPUNEEETUA) via eth1

but this IP address is configured on the DHCP server and the machine is running using this address. After the other machine starts, I get an IP address conflict on the network. Here is an example of the configuration:

host marcelb {
        hardware ethernet 00:1c:c0:71:bc:4f;
        fixed-address 192.168.22.30;
        }

On the dhcp-server 3.0.6.dfsg-1ubuntu9.1 on Ubuntu 8.04 I do not have this type of problem.

@Sebastien: the official language here is English. Although you can open bugs in other languages, this can restrict response until someone fluent in this other language translates it.

summary: - DHCPOFFER assigne une ip déjà attribué
+ DHCPOFFER assigns an IP address already in use (assigne une ip déjà
+ attribué)

@Carlos: thank you for the excellent translation!

Hello Sebastien, thanks so much for taking the time to file this bug report.

Even though you have a fixed IP assigned, you must still manually remove this IP from the range of IP's that you make available to dynamic hosts.

So if you have

       subnet 192.168.22.0 netmask 255.255.255.0 {
         subnet-specific parameters...
         range 192.168.22.1 192.168.22.40;
       }

192.168.22.30 will still be handed out.

You would need to change it to something like this:

       subnet 192.168.22.0 netmask 255.255.255.0 {
         subnet-specific parameters...
         range 192.168.22.1 192.168.22.29;
         range 192.168.22.31 192.168.22.40;
       }

Marking status as Invalid, as this is not a bug.

Changed in dhcp3 (Ubuntu):
status: New → Invalid
