I am using denyhosts on a server
so in a config file
/etc/denyhosts.conf
the following value is set
Quote:
DENY_THRESHOLD_INVALID = 3
which as per their configuration file says
Quote:
DENY_THRESHOLD_INVALID: block each host after the number of failed login
# attempts has exceeded this value.
In my quest to block excessive failed phpMyAdmin login attempts with fail2ban, I've created a script that logs said failed attempts to a file: /var/log/phpmyadmin_auth.log
Custom log
The format of the /var/log/phpmyadmin_auth.log file is:
phpMyadmin login failed with username: root; ip: 192.168.1.50; url: http://somedomain.com/phpmyadmin/index.php
phpMyadmin login failed with username: ; ip:

One on my users is being locked out of his Active Directory account on a daily basis. This occurs between 10 and 18 hours after each reset.

First off, HAPPY FRIDAY TO ALL!
Now for my "problem": I have a ssh server running at my home.
I'm looking for a log file or any service to report the latest login attempts which have failed due to username/password miss match. Is there such utility available for CentOS? (built-in is preferred)
My second question, and more generally, I need a log file of penetration attempts to my server.

Within the past two or three weeks, we have noticed a major increase in the number of our users being blocked by cPHulk for failed login attempts across many of our cPanel servers.
