[Nut-upsuser] nut-server service fails to start at boot

Hello,

     I have a Raspberry Pi model B running Raspbian Stretch.  I have installed
version 2.7.4-5 of nut from the raspbian repos.  I have a CyberPower 1500PFCLCD
UPS.  When I reboot the Pi, the nut-server service fails to start.

root at nut:~# service nut-server status

preset: enabled)

root at nut:~#

I have looked through the syslogs, but have not been able to find anything
obvious.

I have attached an excerpt from the syslog from when the server is rebooted and
the nut-server service fails.  Any help or advice is greatly appreciated. 
Thanks!

Using the LISTEN directive to selectively ignore certain interfaces worked a lot
better when 1) we didn't have to worry about interfaces being removed and
added at runtime and 2) when NUT was guaranteed to start after all of the
network interfaces were already up.

Can you just use "LISTEN 0.0.0.0"? If there is one particular
interface you are excluding, can you handle that with firewall rules?

Can you please try replacing "after=network.target" with 
"after=network-online.target" ?

[Nut-upsuser] nut-server service fails to start at boot

Thanks Charles,

     Looks like setting LISTEN to 0.0.0.0 did the trick.  I use iptables so no
worries on the filtering.
