From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Sort of command that would pull a download that is self executed to the host machine?

That's worded a bit fucky, if I need to elaborate, please chime in.

And when you say "can't know" do you mean it would be impossible to tell strictly through SSH?

the ssh protocol doesn't provide any mechanism for your server to identity the client host architecture, nor does it provide any mechanism i'm aware of to send any payloads back to the host client for arbitrary execution.

The thing is ssh is a protocol and it's implementation is not going to be identical across clients.

So if you found a bug in an ssh client that allowed for this your hypothetical attack vector would only work on intruders using that broken client. ssh is one of the most scrutinized protocols there are and you should be a hero if you found this bug. what you're asking for, if it were as easy as you might hope, well ssh wouldn't be the ubiquitous security connection protocol if it were simple like that right?

Very true. Thanks for the education. SSH to me is just magic portal that lets me talk to my server in my closet lmao

it's a fun thought experiment as it's a very complex protocol
