check if root account is disabled for ssh
enable root login, in /etc/ssh/ssh_config

Hello,

I think it is actually a smart thing to leave the direct login for root disabled on servers.

That said, you need to set the PermitRootLogin option in the /etc/sshd_config file.

i cant disable root login because i need that some application that i work with will have access to my root account so i need to take of my rsa key ...
is there a way to give to another user all the permissions like a root account ???

[b2bwild]

only root can add user permissions/ edit the sudoers file..
if you have physical access to the PC, you can boot up in run level 1
but as you are saying i guess you have have physical access?

it cannot be that complicated to take off my keys back a regular ssh access with no keys only password protection ..

SSH is Secured Shell, so it should use keys, and encryption..
if you dont want it.. go for telent

exactly. telnet doesn't require the keys so that is always a choice. although not a secure choice at all. and as far as the direct root login, i would suggest logging in as another user and possibly using "sudo". with "sudo" you can execute any commands that root can as long as the user issuing the command is configured to do so. and using telnet and logging in directly as root just is not a smart move security wise.

ssh is secure shell cause its encrypted telnet is not ..
who use telnet ?? ?? it's a server not a router ..
every linux server in the world use ssh with or without keys its not a big problem .

As others have mentioned, have you checked the PermitRootLogin option in /etc/ssh/sshd_config? Is it set to Yes?
