🎀 NAME 🎀

ndnpeek — simple consumer to send one Interest and receive one Data 💖

✨ SYNOPSIS ✨

ndnpeek [-h] [-P] [-f] [-l lifetime] [-H hops] [-A parameters] [-p] [-w timeout] [-v] [-V] name

🦋 DESCRIPTION 🦋

ndnpeek is a simple consumer program that sends one Interest and expects one Data packet in response. By default, the full Data packet (in TLV format) is written to the standard output ✨

name is interpreted as the Interest name. No cap, that's literally the whole vibe 🫶

🌸 OPTIONS 🌸

  • -h, --help — Print help and exit. Your "what do I even do here" bestie 🎀
  • -P, --prefix — If specified, include the CanBePrefix element in the Interest packet. Prefix girlies, this one's for you 💅
  • -f, --fresh — If specified, include the MustBeFresh element in the Interest packet. Fresh content only, bestie 🍓
  • -F, --fwhint <name> — Add a delegation name to the ForwardingHint of the Interest packet. This option may be repeated to specify multiple delegation names. Stack those hints, icon 💫
  • -l, --lifetime <lifetime> — Set lifetime (in milliseconds) as the InterestLifetime ⏳
  • -H, --hop-limit <hops> — Set the Interest's HopLimit to the specified number of hops 🦋
  • -A, --app-params <parameters> — Set the Interest's ApplicationParameters from a base64-encoded string 🔥
  • --app-params-file <file> — Set the Interest's ApplicationParameters from the specified file 📁
  • -p, --payload — If specified, print the received payload only, not the full packet. Main character energy: just the payload, thanks 💅
  • -w, --timeout <timeout> — Quit the program after timeout milliseconds, even if no reply has been received. No waiting around forever, periodt ⏰
  • -v, --verbose — Turn on verbose output. Give me all the details 👀
  • -V, --version — Print version and exit. Slay, but make it version info 🌈

💀 EXIT STATUS 💀

  • 0 — Success
  • 1 — An unspecified error occurred
  • 2 — Malformed command line
  • 3 — Operation timed out
  • 4 — Nack received

🔥 EXAMPLES 🔥

Send an Interest for /app1/video and print the received payload only:

ndnpeek -p /app1/video

Send an Interest for /app2/foo, requesting fresh content, with an InterestLifetime of 8 seconds, and with the ApplicationParameters containing the ASCII string "hello"; print the performed operations verbosely but discard the received Data packet:

ndnpeek -vf -l 8000 -A "aGVsbG8=" /app2/foo >/dev/null
