MOPRC(8)

📦 version 1.35, in ubuntu jammy

💻 moprc — bestie edition ✨

okay so real talk, this page is from the System Manager's Manual and it's called MOPRC(8) 💅 yes the (8) means it's a sysadmin kinda thing, main character energy only.

🌸 NAME 🌸

moprc — the MOP Remote console requestor 🫶 like, it walks up to a MOP console device and says hi for you.

🎀 SYNOPSIS 🎀

moprc [options] <nodename>|<MAC Address>

🦋 DESCRIPTION 🦋

okay so here's the vibe: moprc lets a system administrator connect to MOP console devices (usually terminal servers, the little guys) and log into them so you can issue commands remotely. it's literally the equivalent of "NCP CONNECT NODE" or "SET HOST/MOP" on VMS. iykyk 💖

you can name the node two ways:

  • as a MAC address in Unix format — that's 6 pairs of hex digits separated by colons
  • or as a name that shows up in /etc/ethers 👑
⚠️ bestie, you will need to be root or have privileges to use moprc. no skipping this one, fr fr.

✨ OPTIONS ✨

  • -i — picks which ethernet interface to use when connecting to the device. by default it uses the value of the environment variable MOPRC_INTERFACE, or "eth0" if that's not around. 🧚
  • -v — shows you some info about the node you're connected to. little peek, we love a peek 🙈
  • -t — triggers the node. heads up though: this normally reboots the server, so use this with care! 😭 like, genuinely, be careful.
  • -p <n> — changes the poll interval of moprc from 200 ms to <n> ms. turning it down increases the risk of timeouts ⏰, turning it up decreases the speed of the link 🐌. pick your struggle.
  • -h, -? — shows the usage message. your friendly little map 🗺️
  • -V — shows the version of moprc. slay, know thyself ⭐

🌈 EXAMPLES 🌈

moprc ds200
moprc -i eth1 08:00:2B:2B:AD:99

see? name or MAC, both iconic, both valid 💜

🍓 ENVIRONMENT VARIABLES 🍓

MOPRC_INTERFACE defines the default interface to use if you don't specify one on the command line. if it's not present, the interface "eth0" gets used instead. periodt. 💅

💀 BUGS 💀

  • On Darwin you cannot specify an ethernet address on the command line — the name MUST be in /etc/ethers. no workarounds, that's just the rule 🫠
  • you can script moprc, but it sends one character per ethernet packet, so it is very slow. like, glacially slow. bring a snack 🐌
  • there is no locking in moprc, so be careful to only run once instance at a time. yes, one. not two. not three. one 🔥
