is free UNIX/Linux software that controls (remotely and in parallel) switched
power distribution units.
powerman is suitable for remote operation of Linux systems in a data center or compute cluster environment. (See conman for complementary serial console management)
powerman can be extended to support new devices using an expect-like scripting language.
powerman can use ethernet, serial, or pipe connections to communicate with remote power distribution units or power control daemons such as ipmipower from the FreeIPMI project.
