Permission Denied Root Linux
takes a minute: Sign up Here's how it works: Anybody can ask a question Anybody can answer The best answers are voted up and rise to the top PAM login permission denied up vote 1 down vote favorite I have permission denied for root user in linux an OpenSuSE 12.3 machine and can't login to the box either on tty or via ssh. As soon as the user logs in the session terminates and in the message "login [1234] permission denied" is printed. The machine was set to autologin on KDE so that user autologs-in. Any Ideas? Update: I am not sure what has changed on the system, I am not the only one who has access to the box and according to everybody nothing has changed. The only ubuntu permission denied root thing that went wrong on the system was that it takes a backup of a DB on a different machine and there wasn't any space on it. I cleared all the space after some googling updated PAM, that solved the problem. But then the problem repeated when I check the system there wasn't any space again, cleared the system re-installed PAM to no avail. Upgraded the system from 12.1 to 12.3 but didn't help. There isn't a /var/log/secure log. The only relevant message is permission denied. Users are not locked on KDE I can login with any user but not on tty or ssh, can su/sudo. There are lot of files in /etc/pam.d/ which one do I need to check linux login pam share|improve this question edited Jul 21 '14 at 10:14 Tejas 1,59021432 asked Jun 27 '13 at 14:52 rojanu 10613 That's pretty vague problem description What have you done so far and what are the results? What's changed recently? etc... More information can help us get you to what you're after sooner. At this point all I can think to tell you is to check /var/log/secure to see if anything descriptive got printed there. –Bratchley Jun 27 '13 at 15:48 It might also be worthwhile to get the PAM configuration in case there's a problem there. I'd update your question with this information so people have more to work with. –Bratchley Jun 27 '13 at 15:50

Quote Postby shadeless » 2014/04/29 02:36:00 Hi all,I've been trying to solve this problem for a very long time and I now come to ask for help. I recently updated my permission denied server using yum update. Since then I haven't been able to ssh into the account. I know that I am entering the correct password since I use the same password to log in to the physical machine. If I do:Code: Select allssh -vg raphael@zwarg.physics.sunysb.edu

last updated September 13, 2007 in Howto, Linux, Linux login control, Networking, OpenBSD, RedHat/Fedora Linux, Security, Suse Linux, Sys admin, UNIX The idea is very simple you want to limit who can use sshd based on a list of users. The text file contains a list of users that may not log in (or allowed to log in) using the SSH server. This is used for improving security.
PAM (Pluggable authentication modules) allows you to define flexible mechanism for authenticating users. My previous post demonstrated how to deny or allow users using sshd configuration option. However, if you want to block or deny a large number of users, use PAM configuration.A note for new sys adminsBackup all data and PAM configuration files before any modification :)Please be careful to perform the configuration option. Wrong configuration can lock down all login access including root access.Read this Linux-PAM configuration file syntax guideNow continue reading below for pam_listfile.so configration…Use of pam_listfile.so moduleThis PAM module authenticates users based on the contents of a specified file. For example, if username exists in a file /etc/sshd/ssh.allow, sshd will grant login access.How do I configure pam_listfile.so module to deny access?You want to block a user, if user-name exists in a file /etc/sshd/sshd.deny file.Open /etc/pam.d/ssh (or /etc/pam.d/sshd for RedHat and friends) # vi /etc/pam.d/sshAppend following line: auth required pam_listfile.so item=user sense=deny file=/etc/sshd/sshd.deny onerr=succeedSave and close the fileNow add all usernames to /etc/sshd/sshd.deny file. Now a user is denied to login via sshd if they are listed in this file: # vi /etc/sshd/sshd.denyAppend username per line: user1user2
...Restart sshd service: # /etc/init.d/sshd restartUnderstanding the config directives:auth required pam_listfile.so : Name of module required while authenticating users.item=user : Check the usernamesense=deny : Deny user if existing in specified filefile=/etc/sshd/sshd.deny : Name of file which contains the list of user (one user per line)onerr=succeed : If an error is encountered PAM will return status PAM_SUCCESS.How do I configure pam_listfile.so module to allow access?You want to ALLOW a user to use ssh, if user-name exists in a file /etc/sshd/sshd.allow
