💖 NMRPFLASH(1) 💖

okay bestie, welcome to the nmrpflash manual — she's a firmware flash utility for Netgear devices and she is so iconic. this is the nmrpflash documentation page, and yes, you're in the right place. pull up a chair, we're going in 🫶

✨ NAME ✨

nmrpflash — firmware flash utility for Netgear devices. that's the whole vibe. she flashes firmware. to Netgear devices. slay 💅

🌸 USAGE 🌸

nmrpflash [OPTION...]

just the one binary, just the options. simple. clean. main character energy.

🎀 OPTIONS 🎀

heads up bestie, the -i option and either -f or -c are mandatory. like, you literally cannot run without them. no skipping this, fr fr.
  • -a ipaddr — the IP address to assign to the target device. you're picking what IP the device gets 🍓
  • -A ipaddr — the IP address to assign to the selected interface. yes, different from -a. don't mix them up, i beg 😭
  • -B — Blind mode. she does not wait for response packets. bold. fearless. lowkey scary.
  • -c command — a command to run before (or instead of) the TFTP upload. so much power in one tiny flag 👑
  • -f firmware — the firmware file. the whole reason we're here ✨
  • -F filename — the remote filename to use during the TFTP upload. rename it on the way out, why not.
  • -i interface — the network interface that's directly connected to the device. this one is mandatory, no exceptions bestie.
  • -m mac — the MAC address of the target device, in xx:xx:xx:xx:xx:xx format. exactly that format. don't freestyle it 💀
  • -M netmask — the subnet mask to assign to the target device.
  • -t timeout — the timeout, in milliseconds, for NMRP packets. milliseconds!! she's precise ⭐
  • -T timeout — how long, in seconds, to wait after a successful TFTP upload. seconds this time. the unit switch is giving chaos but okay.
  • -p port — the port to use for the TFTP upload.
  • -R region — set the device region. the valid ones are: NA, WW, GR, PR, RU, BZ, IN, KO, JP. pick your fighter 🌈
  • -v — be verbose. give me ALL the details, i want the tea 🫖
  • -V — print version and exit. bye 👋
  • -L — list network interfaces. super useful when you forgot what your interfaces are called (we've all been there 🙈)
  • -h — show this screen. hi hello, here's the help.

🦋 EXAMPLES 🦋

run as root, bestie. root. don't forget.
# nmrpflash -i eth0 -f firmware.bin

and that's it. that's the whole thing. iconic behavior 💅

when you're using -c, the environment variables IP, PORT, NETMASK and MAC get set to the device IP address, the TFTP port, the subnet mask and the MAC address — respectively, in that order, one for each. so your command knows what it's working with 🧚
