Re: [Dnsmasq-discuss] Need some indications to patch dnsmasq, to bypass /64 limit
You should be able to configure DHCPv6 in dnsmasq to handle larger prefixes. You can't do SLAAC address allocation that way, because it depends on a 64-bit prefix and a 64-bit EUI-64 id, but DHCP works. Something like dhcp-range=start-address,end-address,92 The prefix length MUST match the prefix length configured in the local inerface. Thanks for the response i try I make the modification on /var/lib/libvirt/dnsmasq/reseau.conf and kill up the process so my dnsmasq.conf is : ##WARNING: THIS IS AN AUTO-GENERATED FILE.

[Dnsmasq-discuss] timing of dhcp-script for tftp downloads
When is dhcp-script called after doing a tftp download? Is that script invoked immediately, or is it queued operation that has an indeterminate delay between tftp completion and script start? Also, is there any way to know when a tftp download starts vs.ends? thanks Mark___ Dnsmasq-discuss mailing list Dnsmasq-discuss@lists.thekelleys.org.uk http://lists.thekelleys.org.uk/mailman/listinfo/dnsmasq-discuss

Is that script invoked immediately, or is it queued operation that has an indeterminate delay between tftp completion and script start? It's queued at transfer completion. There are at least two sources of delay. 1) Only one instance of the script is running at any time, so a TFTP completion event can be queued indefinitely waiting for a previous invocation of the script to exit. 2) transfer completion is defined as receipt of the ACK for the last block, but some clients never send this: as soon as they have all the blocks they return, and never send the last ACK; also the last ACK may be lost. In this case, the transfer complete at the server occurs after multiple timeouts and retransmissions, at the point at which a failed transfer would otherwise be signalled. Also, is there any way to know when a tftp download starts vs.ends? No, I don't think so.

You'd be able to use any server side language to do actions when a download starts/ends. ___ Dnsmasq-discuss mailing list Dnsmasq-discuss@lists.thekelleys.org.uk http://lists.thekelleys.org.uk/mailman/listinfo/dnsmasq-discuss
