Hilarious... I just put something up a little bit like this. It's something I started a while back and finished up this morning:

It must be the National Day of Command Line File Transfer Utilities.

I wrote this tool 4 years ago :)

We're pretty much in need of tools like this. The alternative is to send the file to file sharing services in other countries then fetch them again from the other computer in the same LAN.

But unfortunately this is still too cumbersome for my personal use cases, which involve Windows machines I don't personally use unless sporadically.

A SAMBA share would be a better option there.

That said, I agree this sort of tool would be useful. I'm not sure why I'd use this rather than piping cat into nc, though.

SAMBA is still too complicated. I was thinking something that didn't need to be installed.

Heh, I was actually having the same issue yesterday, and so I whipped up a quick program to fix it: https://github.com/andyleap/fileportal Not encrypted or anything fancy, only works if the 2 computers can see each other via UDP broadcast, but run `fileportal -i <filetosend>` on one and just `fileportal` on the other and the file will pop out there! (and I have builds for all kinds of platforms up there, windows/linux/macos/netbsd/openbsd/freebsd, and multiple archs for each!)

One critique, this "encryption" is just "seed pseudorandom RNG with a shared int, and then xor each byte with the next value from the RNG". Not exactly a high quality encryption method.

This is correct. Maybe we can say "unreadable" not encrypted :)

What does this do that scp/sftp doesn't?

This is pure socket programming and contains very simple encrypt method. I wrote this for socket programming example about four years ago.
