I’ve often found that something gets left out or forgotten when moving a website from an old server to a new install. I’ve just finished migrating one of my customer’s sites to a new CentOS 5.0 install with Apache 2.2 and PHP 5.1.6, and there’s one single PHP script in the site which uses the SoapClient class.

How to Clear and Delete Last Logged In Users and Bad Login Attemps Log (wtmp and btmp)
Topics: Linux Tags: /dev/null, /var/log/wtmp, Bad Login Attemps Log, btmp wtmp, Change the path and file name, delete the wtmp, FTP or SSH password authentication, Last Logged In Users, login history
In Linux and Unix operating system, it’s possible to use “last” command to display and show the last logged in (and out) users history, and “lastb” command to show and display all the bad login attempts. The users’ login history is been logged and saved in wtmp file while faild login attempts is been stored in btmp file, both files usually located in /var/log directory.
The logging of information into wtmp and btmp is continuous, and can potentially make the wtmp and btmp files grow very to a very big size. The situation is especially true to btmp, which logs failed or bad login attemps to the system, if the administrator does not disable FTP or SSH password authentication, and the server is been attacked via brute-force breaking in attempts, where any wrong user name or incorrect password been logged to btmp.

The btmp log keeps track of failed login attempts. I have seen on a default linux setup with logrotate configured where the btmp log is left out of rotation and eventually grows out of hand. So first you want to make sure that the btmp log is rotated using logrotate with the below information.
Log Location:/var/log/btmp, /var/log/wtmp
To rotate the btmp log add the below to the logrotate.conf file located in the /etc directory. …click here to read more
