To connect, we need data, if you don't know where to get it, don't worry, everything is here.
We will work on a UNIX system.
Step one, introductory.
ssh root @ your_ip, for example
ssh root@92.244.163.58
Step two, unexpected.
We will be asked if we want to join the server with this hash.
The authenticity of host '92 .244.163.58 (92.244.163.58) 'can't be established.
ECDSA key fingerprint is SHA256: b5u9Iaefasfwetrkyuvz4JFKx2uSprD7zi5F9BtYmU.
Are you sure you want to continue connecting (yes / no / [fingerprint])?
We write yes
Further, we are warned that the hash for this IP has been entered, if you reinstall the system on your virtual machine, the hash will change, and you may have the "WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED!" Problem, but you can find its solution here.
Here's a warning:
Warning: Permanently added '92 .244.163.58 '(ECDSA) to the list of known hosts.
Step three is obvious.
Next, we will be asked to enter a password
root@92.244.163.58's password: your_password
After successfully entering the password, we will get into our virtual machine, hurray:
