Allow SSH Root Access

By default SSH would not allow you to SSH login as root user, thus the following error message will appear:
Permission denied, please try again.
You have two options in order to be able to SSH into your Kali Linux. First option is to create a new non-privileged user and use its credentials to log in. Second, allow the root user to access the secure shell. To do so, either edit or insert the following line within the /etc/ssh/sshd_config SSH config file:
FROM:
#PermitRootLogin prohibit-password
TO:
PermitRootLogin yes
kali linux enable ssh root access


After you have made the above change of the /etc/ssh/sshd_config, restart ssh service before you attempt SSH login as a root user:
# service ssh restart
