How to find out the password from ssh through a direct connection of a lan cable?

Question

SSH

I have a server and a laptop. I want to connect a laptop to a server and find out the password from ssh. That is, a direct connection from the server to the laptop.
How can this be done without entering any command in the server terminal

Answer 1

the wording is terrible, figs you will understand what exactly you mean.
If you are considering whether there is a danger that an attacker can steal the password, then if you are watching for messages from the ssh client that the encryption keys have changed on the server (this message is issued the first time you connect, suggesting that you save the information on your client so as not to ask a question), no, you can't know.
But if you do not follow this, then an attacker can use a man in the middle attack by installing his equipment between your laptop and the server (for example, slipping you a fictitious open wifi or slipping your server into a cable break, such exist, and are placed in the network connector) then by slipping their server at your address, an attacker can steal your password.
Here is an example of utilities for this www.securrity.ru/terms/631-mitm-attack.html
ps If an attacker could get into your laptop, your passwords will be stolen without any problems with a simple keylogger or by replacing utilities with infected ones.
----------
ssh is considered the most secure and secure way to connect a client to a server, many utilities (database applications, remote screen access utilities, etc.) usually offer to connect to a remote service directly in the interface without directly, but through opening an ssh connection (and tunneling) and the best methods of hacking revolve around trying to speed up the cracking of passwordless authentication encryption keys through errors in key generators or, for example, access to RAM, where they are temporarily stored.
