Start with telling us what UPS you have. APC makes their software source available, though I am told it does not use the smart mode. The SuSE 7.1 CDs have argoups, smartups, and upsilon. I could not get smartups to work with my APC Back-UPS 650. It detected power failure but never detected low battery and so never did the shutdown. I use the APC SSD package. The communication between slaves and masters is over the LAN. HTH, Jeffrey Quoting Ivan Gustin <ivan.gustin@pu.tel.hr>:
Connect the UPS to one Linux, the master. It tells the slaves to shutdown, wait a period for comfirmation, shuts itself down and turns off the UPS. Details depend on the UPS brand and model and which UPS software you are using.
Wow... Great.
But, *how* tells the slaves to shutdown? UPS software on master, or must I write some script? (I don't use any UPS monitoring software by now).
