....oh. I have used it a few times in the past for the classic task "move large file between two computers that are next to each other, how the hell do I do this simply", but yeah, I can't see how that would be cost-effective for Firefox.

    Ssh with tar is handy for multiple files. Just be careful you're sending and receiving from the right place. Similar for rsync. (cd /right/place && tar -cf - patt*) | ssh remote '(cd /dest && tar -xvf -)' Of course, you can also use the compression flags with tar.

    It does require having an account on both machines though. I've used nc in situations where one machine is owned by someone else.

  Looks like you've got the receiver and sender commands reversed. The sender should use input redirection (< file) to read the file and the receiver should use output redirection (> file) to save the file.

    Look again. :) That's how I have it.

  Could easily introduce compression too: receiver$ nc -l 2000 | zcat > file sender$ nc receiver 2000 < $(cat file | gzip -f) But probably something like `rsync -azvP` will be much better in every way yet still quite portable and prevalent.

Magic wormhole is your friend

  Does magic wormhole do firewall poking or just pass traffic through a 3rd party host? I couldn’t tell exactly what happens if the direct connection doesn’t work.

  Magic Wormhole is a security disaster. Do not use if you have other options. 1) By default, authentication key has only 16 bits of entropy. (I wish I was making this up…) 2) There's no good UI to make the key stronger: you can either use, say, "--code-length 16", which makes the receiving code ridiculously long, or provide your own code with "--code", in which case it's visible to other local users via ps(1). 3) Between "wormhole send" and "wormhole receive" on the other side, anyone on the Internet can attempt to intercept the transfer. Conveniently, you can list all currently valid channel ids (nameplates). 4) If the interception succeeds, the attacker can immediately run "wormhole send" with the same code, so that the intended side wouldn't notice anything is off. 5) If the interception fails, the attacker still ruined the transfer. (DoS) All of this would be fixable, if not the maintainer's bizarre insistence on using weak crypto.

That might be tough. Anyway, if it’s not brute-forceable and/because attacks are visible, it’s not really an issue.

Easy ways to copy files between nearby computers: scp The python 3 equivalent of -mSimpleHTTPServer Samba Or maybe I’m missing something.

  python3 -m http.server

    To specify the port number explicitly: python3 -m http.server 8080 (Listening on port 80 may require more privileges.)

      the default one is port 8000 so permission should be no problem.

      Can also tack on an optional `-d directory_name` to be specific on where to serve from. It's my go to when developing my blog which consists of just HTML+CSS.
