Server :: More Than One Root User \ Manage Key Based Login?
Oct 21, 2010
So if I get their public key for ssh how do I add and then how do I delete it my problem is in .ssh/authorized_keys file I do not understand how to add and how to delete the key so that I can enable and disable root login this way.I am not sure as how do I comment the key assuming that the person sends me his public key then in .ssh/authorized_keysfile how do I add so that a comment can also be added so that I can identify that person as a legitimate user.

When I try to login root from my normal user, I can see this:
Code:
Cannot exec /usr/libexec/openssh/sftp-server: File or directory doesn't exist
(Translateted from my nativ language)
I think that is my bad shell configuration so I check file /etc/ssh/sshd_config and see in the end (this lines couse this bug):
Code:
Match User root
ChrootDirectory /home
AllowTCPForwarding no
X11Forwarding no
[Code].....

i'm trying to use the database that was used by vpopmail and vqadmin with postfix and dovecot. By setting up dovecot to use mysql, i can query username and password for authentication but how do i create a user and edit its information in the database? Poastfixadmin only use database that was created along when installing it.
Any viable option aside from recode postfix to meet my criteria?

I have setup SFTP and it is running without any problems. The problem I have is finding a client that supports key based logins through Linux. I do not want user based logins available and so far the solution works through my Windows machines using WinSCP. The only client I have found for Linux seems to be FileZilla but I have to convert my private key to the FileZilla format which removes the passphrase leaving it nice and insecure.

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.

I 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?

how to forward a user to a Microsoft IIS server under the SAME domain name (e.g. www.MySite.com) depending upon url parameter. My goal is to do this without using a subdomain (e.g. events.MySite.com). The diagram below depicts my goal. I want my linux server to decide whether to forward the user to an IIS server or serve them content from apache based on the url (e.g. www.MySite.com/Events).

I setup a server with vmware esxi 4. I installed opensuse 11.2 and I have successfully setup an internet gateway and I manually configured (static) my client IP. My question is, is there any software or commands that I could use to manage the bandwidth usage for each client? eg. only 5Mbps for 192.168.1.5, 10Mbps for 192.168.1.10, etc

Since 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).
Sep 25 02:24:43 cooler systemd[1]: Child 937 (login) died (code=killed, status=6/ABRT)

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.

After upgrading FEdora 13, user ravi was added. Then after few days neel was added. Both of the users were already existing. 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)

I cannot see what the problem is here. I have installed MySQL 5.1.36 via YaST on my openSUSE 11.2 (32-bit) system.I can log in as root. I can "create user MY_user identified by 'my_passwd';" and a new user is created. But I cannot log in to the database using that new user name. I keep getting the message:
Code:
> mysql -b -u MY_user -p
Enter password:

I have just upgraded my laptop from F8 to F10, and I am unable to login to the system as root user.At login, it provides 2 options, one is the user I created and another called 'other'.On selecting 'other' and providing uid/passwd as 'root/<rootpassword>, it says "Unable to Authenticate User"!!However, when I tried to access my windows partition, it happily accepted the root 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?
