Hello, For a while now I have had this problem that apcupsd doesn't restart properly on system boot - e.g. after power failure. The log appears fine: 2018-10-11 16:43:44 +1100 apcupsd 3.14.14 (31 May 2016) debian startup succeeded I can't remember for sure if the process is running or not. I think it might be, just to confuse matters more. However there is no connection been establed to the device (using SNMP over IP) and "apcaccess" reports dummy values. Furthermore it doesn't do anything on a power failure. If I manually restart it it starts working fine: /etc/init.d/apcupsd restart The logs appear as before: 2018-10-11 18:48:15 +1100 apcupsd exiting, signal 15 2018-10-11 18:48:15 +1100 apcupsd shutdown succeeded 2018-10-11 18:48:15 +1100 apcupsd 3.14.14 (31 May 2016) debian startup succeeded But now "apcaccess" returns correct values. Any ideas? I thought maybe the problem was using the hostname in /etc/apcupsd/apcupsd.conf and putting the lookup in /etc/hosts - should work but was wondering if it was trying to use DNS regardless and DNS is provided by a VM on the box that is still booting. So I now put the IP address in /etc/apcupsd/apcupsd.conf, but it is still failing. Regards -- Brian May <brian(a)linuxpenguins.xyz> https://linuxpenguins.xyz/brian/
