All, (Sorry if this is a repost, I tried without being a subscriber and saw nothing after a day, so I'm trying again after subscribing). I think this is a problem with how sshd uses PAM. Basic scenario: - sshd is configured to use PAM with pam_tally2 - Multiple clients try connecting within a small time frame - Some of the clients fail to authenticate The problem is that the tally is incremented for every authentication, but isn't necessarily reset for successful authentications before another client tries to authenticate. So it goes so...

Hi All, I prepared a Centos 6.8 Minimal server, as part of hardening i added PAM rules under system-auth and password-auth to lock the user account for 30 minutes after 3 failed login attempts. ############system-auth############### auth required pam_tally2.so deny=3 unlock_time=1800 auth required pam_env.so auth sufficient pam_unix.so auth requisite pam_succeed_if.so uid >= 500 quiet auth required pam_deny.so account required pam_unix.so account required pam_tally2.so account suff...

Okay, it's been a while since I've messed with EL4, and apparently I've gone stupid with respect to pam and properly enabling pam_tally2 in an appropriate fashion. My notes are for EL5, so if someone would be so kind as to smack me in the right direction, I'd appreciate it. -- During times of universal deceit, telling the truth becomes a revolutionary act.

...rest is also pretty much default.

I?m looking to configure a centos 7 server to lock out anaccount after 3 login failures. I?ve followed this ? https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/6/html/Security_Guide/chap-Security_Guide-Securing_Your_Network.html#sect-Security_Guide-Workstation_Security-Administrative_Controls ? Section2.1.9.5 Account Locking ? And even rebooted the serverbut it

Hi, I'm currently using, CentOS release 4.8 (Final) and wanted to update the pam_tally module to support unlock_time. I understand this is only support on centos 5.x and up. What are my options for updating pam_tally to support unlock_time, can I simply download and update from a centos repo or should I compile pam. I would appreciate some suggestions. paul -------------- next part

Hi, using PAM, how can I configure how many attempts a user can make to connect, and if exceeding a certain number, block him for a specified amount of time? Any idea what the defaults are?

Hi I am trying to lock users after 3 attempts and then set the timeout before they can log in again. I thought i could achieve this with auth required pam_tally.so deny=3 unlock_time=600 in /etc/pam.d/system-auth but it seems to not be the case - I cant find a working config for this anywhere and i wonder if anyone has one they can share? thanks
