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 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 1

Join Date Aug 2012 Posts 9 Pam - otpw -ssh I don't know if I'm at the right place with my question, it's kind of interdisciplinary. To explain my problem - finally I have to provide access to an embedded system running a custom debian linux on ARM. I have to grant access over SSH (Installed Openssh 6.0p1 with OpenSSL 0.9.8k) using PAM in combination with a one-time-password (OTPW library). I am faceing some problems now during the configuration, in fact i configurated the files as following: in /etc/pam.conf Code: # # The PAM configuration file for the `login' service # login auth requisite pam_securetty.so login auth required pam_nologin.so login auth sufficent pam_unix.so login auth required pam_unix.so login auth optional pam_group.so login account requisite pam_time.so login account required pam_unix.so login password required pam_cracklib.so retry=3 login password required pam_unix.so shadow md5 use_authtok login session required pam_unix.so # # The PAM configuration file for the `sshd' service # sshd auth required pam_otpw.so sshd session optional pam_otpw.so and in /etc/sshd_config Code: ChallengeResponseAuthentication yes PasswordAuthentication no UsePrivilegeSeparation no UsePAM yes but nothing happened
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 di
