Is there key infrastructure allows one running as sudo remotely without prompting password?

http://askubuntu.com – For example, I can use ssh-id-copy to get the key and login to the remote server without entering the password. Is there a similar mechanism to run as root without prompting password? I don't know. If login with a key is sort of safe, then I argue there should be a mechanism like that for sudo. NOPASSWD is not a good solution, however. Thanks. (HowTos)

I've set up sudo not to prompt for password by editing the sudoers file:

myuser ALL=(ALL:ALL) NOPASSWD: ALL

And it works fine, running sudo with no password prompting. But when entering sudo -v I noticed that it prompted for password, only once.

Hi,

I have an issue coming up with my opensuse 11.2.

Its taking too much time to prompting me to enter password after boot-up and it is asking me to enter PAM_MOUNT password.

I entered the password which i use to login and it is not letting me to log-in.

I tried using safe mode and am not able to login through command line.

Websites tell me to use sudo when I have no password, usually tell me one of two things.

It is bad security Or use 'sudo visudo' and the %admin ALL=(ALL) NOPASSWD: ALL line

I would like to not have a password on anything despite the security risks.

Going with option 2, I'm trying to avoid getting prompted to enter a password at all on my account.

So the problem with option 2, is that sudo is

In /usr/local/bin I've the following script called sdown

/usr/local/bin$ cat sdown #!/bin/bash

if [ $# -lt 1 ]; then echo "no time set" else sudo shutdown -h $1 fi

Permssions are 788: -rwxr-xr-- user user sdown

The point is if I run the script it's prompting for the sudo password:

/usr/local/bin$ sdown 13:37 [sudo] password for user:

I’m trying to execute the login command but it fails.

As root (via SSH) I get:

root@server:~# login Connection to 192.168.0.50 closed.

The SSH connection is closed.

After upgrading the os from 5300-06 to 5300-11, this weird behaviour happened.

My system had another unix account, let's call it "abc", purposely configured its uid to 0 for working as a root with all its authorities.

Finding root password 30 weeks 17 hours ago

I installed a Ubuntu and it only has a user. I can login to the system without login. It doesn't ask me for un/pwd. but when I am in, and I want to run some commands as root (sudo), it ask for password and not allowing me to run it. No password works. How can I find password for this user or root?
