How to use "on commit" with isc-dhcp-server (IPV6)

[Fabien Michalon (fmichalo)]

Hi !


Thanks for your response.

I’ve upgraded my dhcp server to the 4.3.2 version and with the same config file, only the “on commit” is executed, nothing happens when the prefix is released or expired.

Is there something wrong in my config ? If not, how can I execute an action when the prefix is released ?

Thanks for your help

Ps : this is my /ec/dhcp/dhcpd.conf :

option dhcp6.domain-search "foo.net";
    option dhcp6.name-servers X:X:X::X, X:X:X::X;
    option dhcp6.preference 255;
    default-lease-time 7200;
    max-lease-time 14400;
    authoritative;
    option dhcp-renewal-time 3600;
    option dhcp-rebinding-time 7200;
    ddns-update-style none;
    log-facility local7;

    on commit {log("========COMMIT===========");}
    on expiry { log("=======EXPIRY==========="); }
    on release { log("=======RELEASE========="); }

    subnet6 2001:db8:0::/48 {
      #I have also tried to put the on commit/expiry/release here (but it stil doesn’t work)
    }
    subnet6 2001:db8::/32 {
      #I have also tried to put the on commit/expiry/release here (but it stil doesn’t work)
    }
    #One client example, I have 4000 others like this :
    host client1 {
     #I have also tried to put the on commit/expiry/release here (but it stil doesn’t work)
     host-identifier option dhcp6.client-id X:X:X:X:X:X:X:X:X:X;
     fixed-address6 2001:0db8:3000::1;
     fixed-prefix6 2001:0db8:3000::/48;
    }

The on [ commit expiry release ] was upgraded to included support for v6 in 4.3.0.
If you are using 4.2.4 you will need to update.
