ethpingall(8)

💖 ethpingall — the manual page, but make it bestie 💖

okay so real talk, this is ethpingall(8) from the EFSFFCLIRG man page collection, and it's genuinely one of my faves because it does exactly one thing and does it beautifully. 🦋

✨ NAME ✨

ethpingall — pings a whole group of hosts or switches so you can vibe check that they're actually powered on and reachable over TCP/IP ping. like, are you alive bestie? hello?? 👑🌸

🌈 SYNTAX 🌈

ethpingall [-C] [-p] [-f  hostfile] [-F  switchesfile] [-h 'hosts']
[-H 'switches']

that's the whole shape of it. flags go in, pings come out. periodt. 💅

🎀 OPTIONS 🎀

• --help — prints the full help text. the "what does this even do" button. use it, love it. 💜
• -C — does the ping against switches instead of hosts. default is hosts, so if you don't say anything, it's host pinging hours. 🫶
• -p — pings all the hosts/switches in parallel. no waiting around one at a time, we're multitasking girlies now. 🔥
• -f hostfile — tells it which file holds the hosts in the cluster. default is /etc/eth-tools/hosts. 🍓
• -F switchesfile — tells it which file holds the switches in the cluster. default is /etc/eth-tools/switches. 🧚
• -h hosts — hands it the actual list of hosts to ping, right there in the command. ⭐
• -H switches — same energy but for switches. hands it the list of switches to ping. ✨

🌸 EXAMPLE 🌸

ethpingall

ethpingall -h 'arwen elrond'

HOSTS='arwen elrond' ethpingall

ethpingall -C

NOTE: this command pings all hosts/switches found in the specified host/switches file. using the -C option selects the default file and/or environment variable to use. for this command, it is totally valid to use a file that lists both hosts and switches. 😌 no cap.

ethpingall -C -H 'switch1 switch2'

SWITCHES='switch1 switch2' ethpingall -C

see how pretty that is? -C + -H + the env var, all living their best life together. 💖

💅 ENVIRONMENT VARIABLES 💅

• HOSTS — the list of hosts. gets used if the -h option wasn't supplied. 🦋
• SWITCHES — the list of switches. gets used if the -H option wasn't supplied. 🐚
• HOSTS_FILE — a file containing the list of hosts. kicks in when there's no -f and no -h. 📁
• SWITCHES_FILE — a file containing the list of switches. kicks in when there's no -F and no -H. 📁
• FF_MAX_PARALLEL — when the -p option is used, this is the maximum number of concurrent operations that get performed. so this is literally the "how many at once" dial. 🔥

and that's the whole page bestie. go ping something. ily. 🫶
