Hi all,
I configured my SME-Server according to the HowTo-WIKI
http://wiki.contribs.org/Uninterruptable_Power_Supply, and it is working perfectly (since Version 7, and now Verion 9).
Now I wanted to configure another computer to be working as a UPS-Slave listening to my SME-Server (Master), as mentioned in the same WIKI later on.
But I did not got any connection from remote.
Now I tested as root on my SME-Server:
[root@smeserver /]# upsc [NameOfUPS]@localhost --> working (I get a long list with all the Parameters from my ups

)
now I tried as root on my SME-Server with the IP-Adress:
[root@smeserver /]# upsc [NameOfUPS]@[IP-AddressOfSME-Server] --> "Error: Connection failure: Connection refused"
so I looked into my messages:
...
ACL in upsd.conf is no longer supported - switch to LISTEN
ACCEPT in upsd.conf is no longer supported - switch to LISTEN
REJECT in upsd.conf is no longer supported - switch to LISTEN
...
Now I understand, that this Version of NUT is only accepting a LISTEN in the upsd.conf!
--> So my suggestion (I hope, this will be working after Upgrade...):
add another File (I called it 60LISTEN):
nano /etc/e-smith/templates/etc/ups/upsd.conf/60LISTEN
+++++++++++++++++++++++++++++++++++++++
LISTEN 127.0.0.1
LISTEN {"$LocalIP"}
-----------------------------------------------------------------
... and VoilĂ ! After a Restart of the NUT everything is working:
/etc/rc7.d/S38nut stop
/etc/rc7.d/S38nut start
and I can connect from other Computer

!
maybe this idea is helpful for someone else...
Best regards
Rainer
