If both UPSes were the same model, purchased at the same time, and used by identically configured computers, you might be OK with the margin provided by the low battery signal. > I was wanting my server to send a broadcast packet across my LAN > to force all PC's (that are still powered by UPS's) to shut down... Note that the solutions mentioned previously require TCP connections, and as such, won't broadcast. But you can definitely configure multiple machines running upsmon.

Re: [Nut-upsuser] Slave as master
Citeren Rob MacGregor : I have a similar question to this as well, in that I have my server set up using NUT with a SOLA-330 (working nicely!) and my desktop is using an APC BackUPS-300 (this model has no serial/USB comms) as the SOLA & APC are rated the same, I was wanting my server to send a broadcast packet across my LAN to force all PC's (that are still powered by UPS's) to shut down... (I have a third desktop without a UPS at this time! and in the event of a power outage this will already be down!) Is this possible to be done? if so, where can I find such information? A machine can be a master for an UPS that it isn't powered by. The documentation has covered this for at least 5 years now ;) There seems to be a lot of confusion about the meaning of 'master/slave' for 'upsmon'. The major difference between 'upsmon' running as master or as a slave, is that when it is a master for a certain UPS, it can command it to shutdown. Whether or not it is powered by said UPS is of no importance for that (although in most cases, both master and slaves will be). See also 'man 8 upsmon' for more information on this. The second thing is, that there is no need for a 'upsmon' to be powered by a UPS in order to run. It is quite possible, to listen in on a UPS and shutdown a system if the UPS is shutting down. See the explanation of MONITOR and MINSUPPLIES in 'man 8 upsmon.conf'.

I have a similar question to this as well, in that I have my server set up using NUT with a SOLA-330 (working nicely!) and my desktop is using an APC BackUPS-300 (this model has no serial/USB comms) as the SOLA & APC are rated the same, I was wanting my server to send a broadcast packet across my LAN to force all PC's (that are still powered by UPS's) to shut down...

Re: [Nut-upsuser] Slave as master
Citeren "Dr. Madhurjya P. Bora" : I need to set up machine as slave which will act as a master to some subordinate clients. The machine is question is a master node a parallel cluster which I want it to act as a master for the computing nodes but set itself as a slave with a master exclusively controlling the UPS elsewhere. Is this possible and how? The question is, why do you want/need this? Please be as specific as possible about the shutdown scenario you're trying to setup.
