locations Description

locations project can keep track of user logins. locations project can keep track of user logins. It is a simple script which can be used to display the locations from which users logged onto your machine from.This was inspired by a similar script discussed in the Perl For System Administration book from O Reilly.By default this script will display all the users who have logged into your box from more than three distinct locations - this may be tweaked via the '--count=N' argument.Alternatively you may ask for a report on all the hosts all users have logged in from, via 'locations --show'.Requirements:· The script is written in perl, and requires the use of a GNU last command. If you're running a Debian GNU/Linux system you will have this. (Basically I require the presence of the '-a' flag to last, this allows the hostname to be correctly identified without truncation).Installation:Either download the tarball and run 'make install' to install the script to /usr/sbin, and the documentation to /usr/local/share, or install it from my apt-get repository.After that create a crontab entry either in your personal file, or under the system wide /etc/cron.{daily weekly} directory:# Report on users who have logged in from more than five machines - # this is potentially suspicious.0 0 * * * /usr/sbin/locations --count=5This will cause the script to be run daily, or weekly.Usage:Usage is fairly straight-forward and obvious, the following options are supported:Usage: locations { options }Options: --count N The maximum number of expected login locations. --help Show this help text. --host host Show all users who logged in from the given host. --list List all users, and the locations from which they logged in. --user login Show all hosts from which the given user logged in. --version Show the version number of this script.
