Bug 1399448

the linked case from the portal is a bit hard to follow, because it talks about various things and there are some incorrect assumptions. In general,

 - enabling both (legacy) network.service and NetworkManager.service together 
   is  supported and possible.
 - note that network.service (aka initscripts) will delegate commands to 
   NetworkManager, if:
     - NetworkManager is running
     - NetworkManager claims to manage the ifcfg-file (e.g. because it doesn't
       contain "NM_CONTROLLED=no"
   So very often, `ifup eth0` ends up calling:
      nmcli connection load /etc/sysconfig/network-scripts/ifcfg-eth0 &&
      nmcli connection up $UUID
   That is, initscripts call out to nmcli.


Anyway. A failure of network.service usually means that one of the ifup commands fails. In that case, the output of the following commands would be helpful:
  journalctl -u network.service
  journalctl -u NetworkManager.service
  ls -la /etc/sysconfig/network-scripts/
  grep ^ /etc/sysconfig/network-scripts/ifcfg-*

also, for more helpful logfiles, please enable debug-logging of NetworkManager before reproducing the issue. In short: edit /etc/NetworkManager/NetworkManager.conf and add there [logging] level=TRACE, followed by `systemctl restart NetworkManager.service` (for more details, see https://cgit.freedesktop.org/NetworkManager/NetworkManager/plain/contrib/fedora/rpm/NetworkManager.conf?id=c90ec2d8c8a12b44c908bf7f80b23059c29f68fa )


Thank you.

Hello thanks for that info and the misconception of Network Manager.


I'd like to find out why the following occurs after an upgrade.

systemctl status network (checking status of legacy network)
We can see in new versions we get bad;vendor preset;disabled


--> Rhel 7.3
 network.service - LSB: Bring up/down networking
   Loaded: loaded (/etc/rc.d/init.d/network; bad; vendor preset: disabled)  < --- bad vendor
   Active: active (exited) since Mon 2016-11-21 19:15:16 CST; 5s ago
     Docs: man:systemd-sysv-generator(8)
  Process: 11107 ExecStop=/etc/rc.d/init.d/network stop (code=exited, status=0/SUCCESS)
  Process: 11294 ExecStart=/etc/rc.d/init.d/network start (code=exited, status=0/SUCCESS)


Previous versions showed it as the following:
--> Rhel 7.2
● network.service - LSB: Bring up/down networking
   Loaded: loaded (/etc/rc.d/init.d/network)
   Active: active (exited) since Tue 2016-12-13 09:22:49 AEST; 1h 55min ago
     Docs: man:systemd-sysv-generator(8)


Why does the new version show this status.

I don't know that.

But as the exit-status seems to be 0, it is likely unrelated to NetworkManager.

Reassigning to initscripts.

--> Rhel 7.3
>  network.service - LSB: Bring up/down networking
>    Loaded: loaded (/etc/rc.d/init.d/network; bad; vendor preset: disabled) 
> < --- bad vendor

This part is fine, network does not have a unit files ("bad"), and it is statically enabled (so not enabled in presets), we should fix both of those things, but it is just a cosmetical issue.

So is there any other bug here?

Hello, 

Thanks, for letting me know that the status "bad" is nothing to be concerned about. 


For comparison, I can see what you mean by the unit causing the error.

in 7.2 ---->
systemctl list-unit-files | grep network
dbus-org.freedesktop.network1.service       invalid 


in 7.3 ---->
systemctl list-unit-files  | grep network
dbus-org.freedesktop.network1.service         bad  


-------------------------------------------------------------------
       |"bad"             | Unit file is invalid or | > 0       |
       |                  | another error occurred. |           |
       |                  | Note that is-enabled    |           |
       |                  | will not actually       |           |
       |                  | return this state, but  |           |
       |                  | print an error message  |           |
       |                  | instead. However the    |           |
       |                  | unit file listing       |           |
       |                  | printed by              |           |
       |                  | list-unit-files might   |           |
       |                  | show it.                |           |
       +------------------+-------------------------+-----------+


Both versions have the symlink pointing to the networkd.service

In 7.2 -->
ls -la /usr/lib/systemd/system/dbus-org.freedesktop.network1.service
lrwxrwxrwx. 
1 root root 24 Jul 10 11:43 /usr/lib/systemd/system/dbus-org.freedesktop.network1.service -> systemd-networkd.service
[root@rhel7b network-scripts]# 


In 7.3 --> 
ls -la /usr/lib/systemd/system/dbus-org.freedesktop.network1.service 
lrwxrwxrwx. 1 root root 24 Nov 21 21:27 /usr/lib/systemd/system/dbus-org.freedesktop.network1.service -> systemd-networkd.service




systemctl --all | grep networkd
In 7.2 --> empty


The different being is that Rhel 7.2 doesnt have this service.

But in 7.3 --> We can see the service is the issue.


● systemd-networkd.service                                                                                       not-found inactive dead      systemd-networkd.service
  systemd-networkd.socket                                                                                        loaded    inactive dead      networkd rtnetlink socket


git clone https://github.com/systemd/systemd.git
I had a look at the systemd code and the vendor preset is called on an 
--> else if condition to determine if an array is empty.


3896         if (i->load_error != 0)
3897                 printf("   Loaded: %s%s%s (Reason: %s)\n",
3898                        on, strna(i->load_state), off, i->load_error);
3899         else if (path && !isempty(i->unit_file_state) && !isempty(i->unit_file_preset))
3900                 printf("   Loaded: %s%s%s (%s; %s; vendor preset: %s)\n",



It cannot find the service, but I cannot track down where the network is looking for the file.
>>>
cat ./system-preset/90-systemd.preset
enable systemd-networkd.service

dbus-org.freedesktop.network1.service this is not related to the classic network initscript in any way. It is a dbus interface for systemd-networkd and again a cosmetic error. We need to move /usr/lib/systemd/system/dbus-org.freedesktop.network1.service out of the systemd package and we already have a bug for that https://bugzilla.redhat.com/show_bug.cgi?id=1404444

Hello Lukas, thanks for that info and clearing up the issue, 

closing bug...
