View 5 Replies View RelatedWhat's the easiest way to have a system script (running as root) execute remote commands over ssh? I've written some scripts that execute commands remotely via ssh, and they work great when I run them as myself, as I've set up ssh-agent and keys for passwordless login. I'd like to call these when my laptop docks and undocks. I've been successful at running arbitrary scripts when docking/undocking, but since the ACPI event scripts run as root, trying to run my ssh script fails during authentication.
I tried using sudo with the -u and -i flags to simulate running the script as my user, e.g.: sudo -u redmoskito -i /home/redmoskito/bin/remote_command which successfully finds my private key and tries to use it, but the ssh-agent credentials are still missing, so it still needs my passphrase.

I have created some users in this server and I would like to login from one user to the other users in the same server without a password prompt by using SSH. I was using rsh for this purpose before, but since it is against our security policy , I have to switch to SSH.I have done the ssh configuration by creating the keys and copying the public keys to the file .ssh/authorized_keys of the other users in the same server.But unfortunately still I am not able to login to other users in the same system WITHOUT a Password.I did the following settings.From user1:
mkdir ~/.ssh
chmod 755 ~/.ssh
/usr/bin/ssh-keygen -t rsa

I have key-based authentication working for one user on a cluster--
Code:
user@thisnode > ssh user@othernode
last login blah blah blah..
user@othernode >
but if I switch to that user and try it, I get an error--

we are running a small cluster (CentOS 5.5) for research in fluid dynamics, using OpenFOAM and Fluent togehter with Sun Grid Engine. For these programs, ssh without password prompt in console is required. So far, I did the method described here: [URL]... with keys distributed at each node. However, imagine a new users needs to be created:
1. Creating user at every node.
2. Create key at every node
3. Distribute key to every node
Makes password prompt threetimes, for 50 nodes - quite a lot. The students dont like that really much, me neither. What I am asking for is any help to make this more comfortable. I am not really a system admin, but more a researcher with some knowledge in admin tasks. Actually, I would like to use a ldap authetication, were passwords are stored centrally. When the user first logs in to a machine, the home directory should be created. I think I can manage it to work.
[Code]...
I can't get this to work on my machines.
So far I have:
1. created a key with ssh-keygen on the server to be logged in to
2. copied the .pub key to my local machine
3. chmod 700 ~/.ssh on both machines
4. chomd 600 ~/.ssh/ic_rsa on the server, and on known_hosts on my local machine
5. added the .pub key to ~/known_hosts on my local machine
my local machine doesn't have an "authorized_keys" file which is what everything is telling me I should append my .pub key to. The only thing that was in my .ssh folder was known_hosts, so I tried that. I also tried making an authorized_hosts file to no avail, changing permissions appropriatly on all files.
Should I/Can I reset ssh in some way? Is there are reason I don't have an authorized_keys file or is my known_hosts file my authorized_keys file?
Would it be better just to uninstall/reinstall ssh?
Well I did something pretty stupid and now I can't log in with my user other than the root user. Basically, I wanted to change my username and so I when to the admin > user & accounts - and selected the account I wanted to change. Anyway I did that and then logged out. Since then all I get when I reseted is a spinning mouse ball and a black screen. I can get into the shell prompt - but I'm not sure how I'd go about fixing this issue I created. At the moment I'm logged in the shell with root, and if I type 'id' I can see my old username, but I think the links behind it are broken.

View 2 Replies View RelatedI created a new user lets call it X. I disallowed the root login from SSH, so I login with X and after I call "#su root" command. But when I login that way, I can't use some commands like "service". I can access all the files, I can even change the sshd_config file but some commands say "not found". Do I need to get X to a group? Or make it some priveledges etc? What should I have to do to run this free of problems?
View 4 Replies View RelatedSince upgrading my Debian/unstable amd64 installation a few days back I can no longer log in as either root or user, whether to SDDM, via the console, or via ssh. When trying with the console, I can see the login message flash briefly on the screen, before the console resets itself.
I can boot into recovery mode, and examine log files. I enabled systemd debug logging and, amid reams of messages, these seem the most pertinent:
Sep 25 02:24:43 cooler systemd[1]: Received SIGCHLD from PID 937 (login).

I have a problem, I have installed Fedora 11. And i need to login as root user.
How to do so?
I've recently upgraded my hardware. Now, the system boots perfectly fine, but I can't login to the tty as root or any other user. Infact yes, I can login, but as soon as it shows Last Login, it exits and then I'm back to a login prompt. I've successfully booted into single user mode, and changed all the passwords, but still it fails. X doesn't start, although I think it's due to the old xorg.conf having the wrong driver.

So when attempting login to neel, we found that every file is owned by ravi. So we did$chown -R neel:neel But after that problem started and when we rebooted the machin, there were no list of users on login screen. (then I connected to that comp remotely, it worked, but somehow I was not able to switch to root) It says incorrect password (though I new it very well). So I went to maintenance mode and changed the root password, and rebooted. Still problem persists.Now I am not able to login as root (from anywhere, login screen , terminal, remote)No list of usernames on login screen ( but i can choose, other and type login-password)

Debian 8/Cinnamon fresh install. /home is being shared with two other OS's, Mint and openSUSE. At the login screen I enter my user name and password and the screen blacks for 1-2 seconds and comes back asking for user name and password. I can login as root. As root I can launch the Group & Users GUI and attempt to set the user's password, and pressing the 'change' button does nothing obvious.
I can set the user's password in a terminal, which reports success. I tried to switch users and login with the changed password and I get the same failure. If I try to login with the original password I get an incorrect password error, suggesting that the password is being processed properly and the problem is elsewhere.
On previous installs with Mate and the default desktop (Gnome) I didn't have this problem. So, the questions are: Is it Cinnamon? Is it an unlucky chance bad install? Config files are typically in /home, which is being shared with Mate and KDE, is this the problem?
