FENCE_AGENT(8)

💖 NAME 💖

okay so bestie, this is fence_cdu — the fence agent for a Sentry Switch CDU, and it does all its little tasks over telnet. It lives in the FENCE_AGENT(8) section of the System Manager's Manual, iykyk. 🎀

🦋 DESCRIPTION 🦋

So like, fence_cdu is a Power Fencing agent and its whole thing is hanging out with the Sentry Switch CDU. It logs into the device via telnet and powers an outlet on or off. That's it. That's the job. 💅

The fence agent takes options on the command line and from stdin. When Fenced execs the agent, it sends the parameters through stdin, periodt. But you can also just run the agent by itself with command line options, which is genuinely so useful for testing and for turning outlets on or off from scripts. 🌸

• -o, --action=[action] — the fencing action you want, bestie. (Default Value: reboot)
• -a, --ip=[ip] — IP address or hostname of fencing device. This parameter is always required. no skipping it 🙈
• -u, --ipport=[port] — TCP/UDP port to use for connection with device. (Default Value: 23)
• -p, --password=[password] — login password or passphrase 🔐
• -S, --password-script=[script] — script to run to retrieve password
• -n, --plug=[id] — physical plug number on device, UUID or identification of machine. This parameter is always required. 🫶
• -s, --switch=[id] — physical switch number on device
• -l, --username=[name] — login name. This parameter is always required.
• -q, --quiet — disable logging to stderr. Does not affect --verbose or --debug-file or logging to syslog. shhh 🤫
• -v, --verbose — verbose mode. Multiple -v flags can be stacked on the command line (e.g., -vvv) to increase verbosity. stack 'em like bracelets ✨
• --verbose-level — level of debugging detail in output. Defaults to the number of --verbose flags specified on the command line, or to 1 if verbose=1 in a stonith device configuration (i.e., on stdin).
