Hi Cristian,

listening
on one of its statically configured IPv4 addresses and with a fixed size
pool of
leases determined from it.

Hi Lennart,
I am tempted to say that we should try to apply as much information from
DHCP as we can by default, but make sure it doesn't become a security
problem. i.e. we should probably use metrics or so so that manual routes
always win, or routes to other interfaces.
I think using
Hi Michael,
I think the lease should be remembered and reused in this case.

out it should send the same identifying information to the server, and
hence be given the same lease back again. Wireshark should tell you if

Hi Lennart,
There seems to be no way in systemd-networkd to put a link in
Promiscuous mode. This is needed to make macvlan work correctly
(Otherwise it receives no traffic with its mac address as the
destination). If I am not mistaken this could be a boolean in *.link
files.

Hi Lennart,
Now that networkd can send the systems hostname to the dhcp server, I would
find it useful to have an option to override the hostname that gets sent.
In my use case, I would like to setup a number of macvlans with different
hostnames.
Something as simple as

Hi Greg,
This patch set implements a DHCPv4 client library named libsystemd-dhcp

Nice stuff. Where did this code come from, conman? If so, for some

Hi Tom,
I just pushed a change[0] which allows the match syntax

We had a discussion on IRC whether we should call it Type=wired or
Type=ethernet. I think the former may be more intuitive, but the
latter seems to be more in line
Hi Tom,
we can easily update ConnMan to handle DEVTYPE= and DEVTYPE=ethernet. That
is an easy change and will keep things working. As I explained in the other
reply, the main reason for DEVTYPE=something is to detect that it is a

Guess what we have done that twice now and both of our clients are

ConnMan is a single daemon solution doing NTP, DHCP and DNS all in
