How to login to server via SSH as root?

Question

linux

I fully configured the Debian 8 x64 server on VirtualBox, I log in under the standard IP (192.168.56.10), I can easily connect via Putty, but I enter the data and writes that the data is not correct, I return to virtualbox, restart, enter the same data as in putty , I'm all right. Please help, what is the reason why I can not log in not from root not through a regular user

Answer 1

/etc/ssh/sshd_config
Parameter PermitRootLogin
But remote login as root is not the best solution.
Log in as a normal user and use sudo.

Answer 2

Because it is NOT possible to do so .
Do not go into the reasons why this should not be done yet - just take it on faith, as a mathematical axiom - remote login under the root is FORBIDDEN .
Create a regular user, write it to /etc/sudoers, log in as a user, and do commands to manage the system through sudo

Answer 3

Set up authorization using SSH keys, it's much more convenient and you don't need to enter anything.

Answer 4

if it's not too late.
Is there any certainty that through putty you get to the virtual machine, and not to the host's sssh?
you can try ssh [email protected] (to yourself via sssh) in a virtual machine
? then you need to deal with where you connect from putti.
I usually configure the network as a bridge in the virtual machine settings, and it receives a "normal network address" and you can connect to it from any device on the network.
all of the above options are good, but relevant after resolving the connection issue.
