 It does not. I'd be open to exposing the handed out leases through the
 sd-network library, which then resolved could pick up (so patches
 welcome!). But maybe Lennart should comment on the resolved part
 first.

Yes, I'd like some kind of integration of NSS and networkd's dhcp
server. But I don't think resolved should be involved. Instead, we
should add another NSS module that queries the DHCP lease database via
dbus, similar to how nss-resolve talks to resolved or nss-mymachines
talks to machined. Of course, we can make that happen only when
networkd gets a bus interface, which is not before kdbus, because it
needs to run in early boot where dbus1 is not available...

Note that if you hand out a lease to a local container, nss-mymachines
will be able to resolve it for you.

[systemd-devel] Systemd-networkd DHCP Server DNS integration?

2014-11-17 Thread William Wilhelm

Hi,

I'm building a router and have been experimenting with DHCPServer=yes for 
the LAN side of things. It's been working well.
I ask if there is any integration between the networkd DHCP server and 
systemd-resolved? When the server hands out an address does it register a 
hosts entry for the client's hostname with resolved?


Thanks,
Will
