ssh root denied 1

[alexia32]

Hi,

I am trying to allowed my nim server to ssh to the clients without asking the passwd but I still have the passwd asked and even if I put the good passwd I have access denied...

I have put the id_dsa.pub on the authorised file on my clients.

Do you know where I have to modify to allow root to login as ssh?

I think the user root is really somewhere not allowed but I want to modify it on the nim server...

Thanks in advance

Check your /etc/ssh/sshd_config file on the client, there is an entry like this:

PermitRootLogin no

Change "no" to "yes" and restart sshd.

Beware though, this not good practice as it will allow anyone to log in with root remotely. Use with care.

Hi,

Thanks a lot!! It was set to no and they want it to be set to no...... So I will write a script that use sudo and create a user that have root access to do it...
