CentOS 5 - locking out users afer 3 failed attempts
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

pam_tally question
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 a...

Locking user accounts
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.

OpenSSH-3.6.1p2 PAM Problems
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 ideas?...

pam update
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.

Strong security in user's accounts and paswords..
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

Feature request: FAIL_DELAY-support for sshd
....
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 cra...

Need IP on failed logins in logfile
...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 listi...

SSHD Feature Request
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
