Rouji / nc2p

netcat -> HTTP POST shim

netcat to POST

Receives raw data via TCP (e.g. sent using netcat) and POSTs it to an HTTP(S) URL.
Useful for adding termbin-like behaviour on top of existing HTTP-based file hosting sites.

Building:

meson build
ninja -C build

Usage:

./nc2p
Usage: ./build/nc2p [-l listen_ip] [-p listen_port] [-t connection_timeout] [-f form_field] [-n filename] upstream_url

Note about timeouts

termbin accepts files as valid, even if clients don't explicitly close the socket after EOF and run into the timeout instead. That has the benefit of your netcat implementation not needing to do that (some do, some don't, some only optionally). Downside is that those that don't will make you wait for the timeout, and if your connection is bad you're potentially left with a truncated file on the server.

That's mostly fine for smaller files and especially text, but kind of bad for anything else.

nc2p will by default (compile-time switch, see ALLOW_TIMEOUT) cancel the HTTP POST to upstream, if a client times out. That does mean you might have to add -N to your netcat command. nc2p will (try to) tell clients about that when they time out.
