When I try to ssh into my friends computer in the same LAN with his host-name and IP I am able to login successfully. But when I try to login using the root user password it shows me the following error. What could be the possible reason?

ssh [email protected]
[email protected]'s password: 
Permission denied, please try again.
[email protected]'s password: 
Permission denied, please try again.
[email protected]'s password: 
Permission denied (publickey,password).

  • In the host /etc/ssh/sshd_config add (or modify) the line: PermitRootLogin yes

  • Thanks for that. I wish to know whether there exists any other options available to ssh without enabling this thing in sshd_config

  • Well, maybe there is one I know not, but it would be really strange (from a security point of view), if you could be able to login as root on some computer which don't allow it explicitly. Anyway, why logging as root ? If you use an account member of the sudoers group, you will be able to do anything you could do as root.

There are three ways to configure SSH. Al three ways have the same options wich will be passed as arguments to SSH.

1-System wide configuration file: /etc/ssh/ssh_config

2-Personal configuration file: ~/.ssh/config

3-Command line arguments

  • Yes, but you can't setup the login as root permission from the client side which obviously what's OP wants.

You need to check if the SSH root connection is activated in the remote laptop !

Open the file /etc/ssh/sshd_config

vim /etc/ssh/sshd_config

Turn the PermitRootLogin option from No to Yes

PermitRootLogin Yes

Reload the ssh service

/etc/init.d/sshd reload

Hope it helps ...
