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

[Fabien Michalon (fmichalo)]

I try to use the "on commit/lease/expiry" trigger in isc-dhcp-server(IPV6 - 4.2.4).

I made prefix delegation, and I have problem with updadting routing table, so i want to use the isc dhcp triggers to manually update routing tables when a commit or release happen.

First I make a simple test but it doesn't work, I have disabled ddns-update according to the documentation but nothing happens. I don't have any error when I start the server.

my /etc/dhcp/dhclient6.conf is like this :

    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;
    }

I've tried to put the triggers in the "host client1" scope and in the subnets scopes but it is the same: nothing happens.
The DHCP server works properly because the client receive its prefix but the text is not added to the log. (And when I try to use execute function like `on commit { execute("/home/user/myscript");}` the script is not executed)

So Have I make something wrong ? Or if someone have an idea to make it works?

Thanks in advance for your responses :)
