Here’s nifty toy, with a clever name too: woof, short for “web offer one file.”
It’s a one-shot, single use server with a very primitive web interface for uploading as well.
But the cool part of woof, in my meager opinion, is that all of those things probably require a running daemon.
woof just awaits a connection, and sends its information. Of course, there’s no security, probably no encryption unless you do it manually, and so forth.
I only ran into one jam with woof, and that was trying to send files out beyond my router.
For whatever reason, I couldn’t arrange woof to listen beyond my home network. I blame my router settings, but if you have any ideas, I am willing to listen.
