If you want to disable this sort of behaviour you can disable SSH from sending keys automatically, and then tell SSH which identity files need to be sent to each host.
In your .ssh/config, something like:
# Ignore SSH keys unless specified in Host subsection
# Send your public key to github only
ssh -o IdentitiesOnly=yes -i /dev/null host
In what manner?
> Specifies that ssh(1) should only use the authentication identity and certificate files explicitly configured in the ssh_config files or passed on the ssh(1) command-line, even if ssh-agent(1) or a PKCS11Provider offers more identities.
Configuring your ssh correctly would avoid a specific system to link you to another one. More privacy issue than security.
I was curious about this, so I did some research.
First, if you run `ssh -v`, you can see that there's a key exchange (eg, Diffie-Hellman), then a cipher and MAC are negotiated, and only once you get to the user authentication portion do your public keys get sent to the server.
So, only Alice and Bob can see the public keys: not Mallory.

If I recall correctly, if you specify it for a single host, it tries all your default keys then tries the specified key if nothing else worked. Which seems weird and wrong to me, but what do I know. Anyway, thanks for (possibly) solving a mystery for me.
Configuration options may be separated by whitespace or
optional whitespace and exactly one `='; the latter format
is useful to avoid the need to quote whitespace when
specifying configuration options using the ssh, scp, and
sftp -o option.
I would love to see something that stays with the stuff I actually like about them. Philosophy and psychological exploration can be fine but I would absolutely love to see a show like one of those that stays closer to the ground.
GitS is primarily cyberpunk as I see it rather than focused on hacking. Hacking is just an element. Lain is focused on philosophy, psychology and spiritual weirdness and uses technology for aesthetics and as a tool to explore the bigger themes.
I'd love something like a heist-movie that stays close to the keyboard, like the most techie and coherent parts of Mr. Robot.
Human societies and technological infrastructure are already complex enough to behave sort of like intelligent beings. They comprise humans and machines but are inhuman and more than mechanical. I find Lain to be one of the most thought provoking examination of the psychology of such super-intelligence that I've enjoyed.
- The research scenes in The Girl with the Dragon Tattoo.
- The texting scenes in Personal Shopper and House of Cards.
Does anyone have any other recommendations of close-to-the-keyboard style portrayals of communication, research, and hacking?
And GITS is not? I relate more with the Laughing Man than whatever the hell happens in SEL. You know the girl is dead and her spirit lives in a computer, right? SEL has more to do with spirituality than technology while GITS is almost exclusively tech and politics focused.
I had a chance to see the new movie a week ago and was pretty blown away by the levels of future-shock I experienced. I think they did a wonderful job building off the anime and manga to re-build the GITS world in live action. The first half of that movie had me enthralled at how good of a job was done here. I really think from set-design, costume, and setting perspectives this movie on par with visual feasts from the 70s/80s like Bladerunner, Dune, Star Wars, or Alien.
Story-wise its a poorly paced and milquetoast origin story that we've seen a million times. If this production had a more daring script I think we'd see the wisdom of trying to bring it to the big screen as live action. "Mindfuck" anime like SEL really isn't going to translate well, and trippy mindfuck stories have been beaten to death by now and are just another tiresome trope. Worse, it would have even less of an anticipated audience thus budget which would force the production into cheesy B-movie territory. Its also a non-existent franchise while GITS is an established fan favorite and for fairly valid reasons including a focus on the realpolitik of power, terrorism, technology, cybercrime, etc which a lot of other tech-oriented stories simply get wrong and lean far too often on a simplistic 'right vs wrong' moralism.
For those who haven't seen the live-action movie, Kotaku just put up an article showcasing some of the concept art:
(Except for die-hard fans of GitS, I would not recommend the new movie.)
Tbh I really liked the spiritual themes from GitS. It's in the original movie, also in 2004 Innocence, and at the finale of 2008 Solid State Society (not going to make sense without seeing the whole anime series start to finish)
Also to be fair, when we look at the original movie, its more about AI rights than an avante-garde pondering of "dead waifus living in the ether" SEL is based on. I would classify these two things are completely different categories. One is a fairly rational take on the age old "Are AI alive" argument while the other is more or less fantasy dressed up as sci-fi.
>seems to have more to do with being an actual hacker

I wish the new anime Yoshitoshi ABe was planning, Despera ,would come out soon but that doesn't seem like the case.
It's also not really about hacking the way a "hacker" movie is.
Bit of a callout  to Be, I should think, cf. . That's neither Unix nor Apple, although it's fairly close to both.
But I am checking out Serial Experiments Lain right now, thanks for the recommendation! I love GitS to death and it might be my favorite anime/manga franchise but it still feels a little bit too corny every time someone gets called a Super Wizard Class Hacker
Another recommendation (though completely unrelated to the discussion) is Berserk, quite possibly the best anime/manga I have seen/read, and the manga really is a must-read after you finish the anime.
Tried the classic telnet towel.blinkenlights.nl but noticed that it doesn't allow me to connect. Anyone know if it's still available somewhere?
On IPv6, it works (as mentioned by others already).
So maybe only works within Europe, or has some other IP/location restriction.
The actual “movie”, not so much

I'm not even being glib. That is what it is.
The title is "GHOST IN THE SHELL | remake", please leave it as such.
edit: Thank you!
