🌸 NAME 🌸

fence_powerman — Fence Agent for Powerman 🫶

---

🦋 DESCRIPTION 🦋

okay so fence_powerman is a Power Fence Agent for the Powerman management utility, and it was literally designed for LLNL systems. no cap. it's giving specialized.

the fence agent is so flexible bestie — it accepts options on the command line as well as from stdin. when fenced execs the agent, it sends parameters through stdin. but the agent can also be run all by itself with command line options, which is highkey useful for testing and for turning outlets on or off from scripts. main character energy fr fr 💅

• -u, --ipport=[port] — TCP/UDP port to use for connection with device (Default Value: 10101)
• -n, --plug=[ip] — IP address or hostname of fencing device (together with --port-as-ip)
• -q, --quiet — disable logging to stderr. does not affect --verbose or --debug-file or logging to syslog.
• -v, --verbose — verbose mode. multiple -v flags can be stacked on the command line (e.g., -vvv) to increase verbosity. stack 'em like bracelets 💜
