[EN] |Solved] systemd-networkd misconfigured: Network lost
« on: 2015/06/29, 13:53:56 »
Following the recipes of the thread http://forum.siduction.org/index.php?topic=5580.0 I switched from ifupdown to systemd-networkd but, unfortunately, did not succeed.
That is, no more working (wired) internet connection.
Code: [Select]
# ping 8.8.8.8

connect: Network is unreachable


Network service is active, but with a name conflict:

Code: [Select]
# systemctl status systemd-networkd
● systemd-networkd.service - Network Service
   Loaded: loaded (/lib/systemd/system/systemd-networkd.service; enabled; vendor preset: enabled)

Any hints appreciated.

If I'm not wrong, systemd configuration files are case sensitive.
Does

Code: [Select]
[Match]
Name=eth0
work?

Thanks, Gabriel, for your quick reply.
Indeed, the "name error" vanished, you were right  :) .
Unfortunately network still unreachable, configuration error remaining  :'(

Please try for DHCP= either 'ipv4' or 'both' and see if that changes something.

Hi samoht,

did you disable networking.service and/or NetworkManager.service? These services do not need any more your system with the networkd runs.

Yesterday after d-u had delivered a fresh systemd

Code: [Select]
# LANG=C apt-cache policy systemd
systemd:
  Installed: 221-1
  Candidate: 221-1
  Version table:
 *** 221-1 0
        500 http://ftp.de.debian.org/debian/ unstable/main amd64 Packages
        100 /var/lib/dpkg/status
     220-7 0
        500 http://ftp.de.debian.org/debian/ testing/main amd64 Packages

network worked again  :) .

Code: [Select]
# networkctl list
IDX LINK             TYPE               OPERATIONAL SETUP
  1 lo               loopback           carrier     unmanaged
  2 eth0             ether              routable    configured
  3 eth1             ether              off         unmanaged

3 links listed.

Code: [Select]
# less /etc/systemd/network/eth.network
[Match]
Name=eth0

[Network]
DHCP=yes
# DHCP=ipv4
# DHCP=ipv6
# DHCP=both

Thanks to all supporters
