One thing I've noticed is that when connected via Ethernet & DHCP,
openSUSE 42.2 does not use duplicate address detection (RFC 5227) when
bringing the connection up. DAD is used to avoid IP address conflicts.
On the other hand, Windows 10 does use it. However, DAD is used on 42.2
for link local connections, where it is mandatory, so the code for doing
it is there. Any idea why Linux doesn't use DAD on IPv4 DHCP? It's
also mandatory on IPv6, using ICMP6 Neighbor Discovery.
When DAD is …
[View More]used, the computer will arp it's assigned address, but with
0.0.0.0 as the source address. If there is no response, it will assume
the address is safe to use and then send out a gratuitous arp, to let
all the other devices know the address is being used.

I have a headless machine which I access via ssh. How would I execute a
command such as "akaonatictl restart" on that machine?
tks

Hello:
I noticed that network-manager configured networks are different for
different users.
I would like to make a default system setup and I want that
network-manager offers
every user the same choices.
I would like to setup some default connections as admin. All users
should see the same
default connections, able to start and stop those connections but not
able to modify
the connections (add new connection or remove connection). (That is, I
would like to
imitate the previous smpppd/…
[View More]kinternet/ifup combo behavior with nm.)
How to do this in Leap 42.2? Does it matter which nm-applet is run (kde
or gtk)?
Links to good network manager manuals or howtos are also welcomed.
Thanks,
Istvan
