ssh debian and ubuntu

Login and su into root. Edit this file:

nano /etc/ssh/sshd_config

Scroll down for a bit and you’ll see a line that says

PermitRootLogin without-password

Put a # and a space in front of this line like so:

# PermitRootLogin without-password

now rewrite it on a new line like this:

PermitRootLogin yes

Now save the file and restart the SSH server.

/etc/init.d/ssh restart

Now you can SSH into it directly as root. Congrats! Your old insecure ways of doing things have returned.

On Ubuntu

sudo passwd

Changes in /etc/ssh/sshd_config

Change PermitRootLogin

PermitRootLogin yes

You may also have to check value of PasswordAuthentication. If it is set to no then set to yes

PasswordAuthentication yes

Then restart SSH:

service ssh restart
