powerman: powerman (cluster power management utility) powerman: powerman: Powerman is free UNIX/Linux software that controls (remotely and in powerman: parallel) switched power distribution units. It was designed for powerman: remote power control of Linux systems in a data center or cluster powerman: environment, but has been used in other environments such as embedded powerman: management appliances, home automation, and high availability service powerman: management. powerman: Powerman can be extended to support new devices using an expect-like powerman: scripting language. It communicates with devices natively using powerman: telnet, raw socket, and serial protocols. It also can drive virtual powerman: power control devices via a coprocess interface. The coprocess powerman: mechanism has been used to extend powerman to communicate with powerman: devices using other protocols such as SNMP, IPMI, Insteon, X-10, and powerman: VXI-11. Powerman can control equipment connected using any powerman: combination of the above methods and provide unified naming for the powerman: equipment and parallel execution of control actions. powerman: powerman: Packaged by Georgi D.
