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

hi, i just noticed that my pam_tally config has stopped working. it used to work in 3.6.1p2, but since then hasn't. i configured openssh like so: ./configure --with-tcp-wrappers --with-pam --with-privsep-user=sshd --with-md5-passwords --with-ipaddr-display and i do have "UsePAM yes" set in sshd_config. i've tried...

Hello all, At this moment I am running a samba-ldap-pdc. This works really good. But what worries me is the following thing: user accounts never get locked. This is a problem cause anyone can guess or use bruteforce to enter password. Is there a solution/workaround for this? I want the following situation : when a user tries to logon for 4 times I want the account to lock out the account.

recently we upgraded a bunch of systems to OpenSSH-3.6.1p2. alot of our systems have automated logins for backups or systems checks with ssh-keys, but (i think) as a result of the Openwall/Solar Designer patch, pam_tally is incrementing off the scales. pam_tally is tallying failed logins for keyed-only accounts: attempts are made to authenticate those accounts via password authentication before using keys. i'm not a coder so i don't have a fix, but i don't think it should be that hard to fix. any idea...

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 --------------...

Hi, I have some databases running on CentOS4 with users accessing the shell (bash), so I'd like to strong the security on my server in user's accounts and passwords.. I mean, enforcing strong passwords, min/max age passwords, locking passwords when you fail 3 times, and all this stuff. Is there any package which do this work? Any tutorial? Thanks in advance Regards Israel

.... I searched this day in the net for solutions and tried some things in the source code. This are my experiences: 1) Very much people ask for a FAIL_DELAY-feature (Source: Google, Newsgroups, Mailinglists, ...) 2) The work-arounds are not perfect: a) Some people suggests using /lib/security/pam_tally.so (this PAM-module denies access to accounts after too many login failures). Unfortunately this module can result in denial-of-service. b) MaxStartups-Option in /etc/ssh/sshd_config. This drops new connections if there are too many unauthorized login attempts. It may help a bit against c...

...of the computer's IP? Perhaps this all can be submitted somewhere as an upgrade request? I think for the sake of Internet security in this day-and-age of cyber criminals it would be useful to know the IP of attackers so appropriate countermeasures could be taken. Rowland, I will investigate pam_tally[2] to see what it does. I've not heard of it before. I suppose I could also run tcpdump continuously against the specific port(s) where such logins can occur, but that is a bit of work, esp. since the timestamp of the samba log message is detached to a separate message preceding the one lis...

With the increased number of "brute force" login attempts against port 22, I am concerned that an intruder may actually stumble accross a valid user/pass combination. To combat this, I would like to request an sshd_config option that would cause the running sshd parent process to keep track of login failures by IP address. If there are more than X number of login failures for a
