Oct 03, 2012 sudo: PAM authentication error: Module is unknown / Newbie Nov 30, 2015 PAM: Authentication failure for root from xxx.xx.x.x Thanks a lot for replying. Here are some updates. I added debug to pam_google_authenticator and this was the debug output.

Understanding PAM Authentication and Security PAM is about security - checking to see that a service should be used or not. Most of us first learned about PAM when we were told that login was using it, but PAM can do much more than just validate passwords. A lot of applications now use PAM - even things like SAMBA can call on PAM for authentication. sshd[902]: debug1:PAM: password authentication failed for sshd[902]: debug1:PAM: password authentication failed for an illegal user: Authentication failure Unknown cipher in list: TLSv1 SSL routines:SSL23_GET_SERVER_HELLO:sslv3 alert handshake failure Unable to login into cpanel/whm with one click
I faced the same problem. whenever i typed in chsh it use to prompt . chsh: PAM authentication failed But I solved it by doing some modification in the /etc/passwd file. Users of kali-linux
Jul 17, 2020 · Another possible cause of the “passwd: Authentication token manipulation error” is wrong PAM (Pluggable Authentication Module) settings. This makes the module unable to obtain the new authentication token entered. The various settings for PAM are found in /etc/pam.d/. Linux uses PAM (pluggable authentication modules) in the authentication process as a layer that mediates between user and application. PAM modules are available on a systemwide basis, so they can be requested by any application. This chapter describes how the modular authentication mechanism works and how it is configured. Thanks a lot for replying. Here are some updates. I added debug to pam_google_authenticator and this was the debug output.

By default, pam_tally2 module is already installed on the most of the Linux distributions and it is controlled by PAM package itself. This article demonstrates on how to lock and unlock SSH accounts after reaching a certain failed number of login attempts. I'd suggest you start another thread for your new questions (someone may help you that is unaware about SSH questions), and to be honest, if I were you, I'd use key-based authentication with SSH and not password based (except if it is needed for some un-explainable reason). Here is the state of the system-auth-ac Pam file: #%PAM-1.0 # This file is auto-generated. # User changes will be destroyed the next time authconfig is run. auth required pam_env.so auth required pam_faildelay.so delay=2000000 auth sufficient pam_unix.so nullok try_first_pass auth requisite pam_succeed_if.so uid >= 1000 quiet_success auth required pam_deny.so account required pam_unix.so
