Create user with sudo ability to root.

Hi All,

I need to give an user sudo ability to root.
We have also generated RSA key but unable to proceed further.

For example after a user logs into the server normally and when he executes below command

$ssh root@server_name

This should take you to root prompt #

Please help me.

How is sudo involved in this question?

Generally you cannot login to root directly over ssh, check the 'permitrootlogin' option.

What I am confused by your post is that do you need a user say xyz to have root permissions through sudo?
If this is the case, you need to edit your sudoers file.


ssh to the server with root user?

what Corona688 said should resolve the issue. There are many other options in ssh config that will decide which users are allowed to ssh to the server.

After creating the ssh key for the user, you need to add the public key under user's ssh folder of the target server.

Hi Guys,

Thanks for your support.
I had got the solution from one of the posts and had it resolve my problem. I thought of sharing it here.

Step 1 --- Login to the physical server and navigate to /usr/local/bin

# cd /usr/local/bin

Step 2 --- Take a backup of keyaccess file

# cp –p keyaccess keyaccess_original

Step 3 --- Add an entry in the keyaccess file

# vi keyaccess

ssh-rsa AAAAB3NzaC1yc2EAAAABJQAAAIEAlems+KrluE84R3dpuS7mPU/uGJqm77YjWbx+Yqvj8geijykD55qf2QeqSiJc0dVakk7tykTm60++HwCAGv5DFArm1DSP+nDRd0pK68FsQywH9lblYj1daLrH/xL/WQypmg5sM2CqXFHPMqPX5+Vm8bu6dXQbLQ5bXNZEDEcBTPU= Testuser

Step 4 --- Execute the keyaccess script file

syntax: ./keyaccess -a username zonename

I hope my posting would help someone in life somewhere....
