[opensuse] No IPv4 duplicate address detection (DAD)
by James Knott 02 Jul '17

02 Jul '17

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 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. https://tools.ietf.org/html/rfc5227 -- To unsubscribe, e-mail: opensuse+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse+owner(a)opensuse.org

I have a headless machine which I access via ssh.

[opensuse] network manager system default setup
by Istvan Gabor 02 Jul '17

02 Jul '17

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/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 -- To unsubscribe, e-mail: opensuse+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse+owner(a)opensuse.org
