Script Name Alert Manager Alert Manager was created to run an alert command, monitor the status of that command's output, and if it fails run a different (fallback) command. It has a very flexable configuration file that allows creation of "alert chains" - chains of alerts, each with their own alert command, fallback-command, and other advanced options. It has a method for passing messages from the command line into the various alert commands defined in the configuration file, and many other useful features. LogDog LogDog is a tool that monitors messages passing through syslogd and takes action based on key words and phrases. LogDog has a configuration file which allows you to specify a list of key words or phrases to alert on, and a list of commands that can be run when those words are encountered. Version 2.0 is a complete re-write and has many new features. See the website for more info. IP Accountant IP Accountant allows you to keep an Rx/Tx byte count for each address aliased to a single interface. It features optional graphical output. Perl Digger Perl Digger is a freeware Perl script to dig for information about the server-side environment including a list of all installed Perl modules with a handy link to their documentation at CPAN. The server information includes detailed OS version, CPU + memoru + disk utilizations, etc. scanAlert ScanAlert was built to analyze iptables log entries in real time and report detected port scans to syslogd. From there you can use a log monitoring daemon (like logdog) to take action if desired, or you can manually review the logs later if you prefer. It does not need special permissions, it doesn't listen on any network ports - it receives iptables messages from syslogd via a FIFO. It runs as a daemon, and supports the HUP signal to reload, has multiple debug levels, and does not require any special perl modules. ScanAlert has a straight forward interface and configuration file making it easy to use and configure. PEANUTS PEANUTS is a console-based Internet user management system, which is perfect for system administrators who normally do things like adding virtual hosts or new users by hand. It allows such tasks to be completely automated. Directory Space Manager (dirspace) This script will keep track of any directories under a main directory that you specify. The most obvious use for this is keeping track of users homedirectorys or webspace directorys on a webserver (isps, webspace providers, email systems, etc.) It will email you if a certain directory gets too big. Advance Bandwidth Script to monitor incoming and outgoing bandwidth in real time. Provides reports month, day and hour wise. Useful for load balancing and detecting misuse of server. ShellCommander Can't get a shell account at your ISP Want to be able to use normal Unix commands to maintain or clean up your directories, create backups, install software and debug scripts Execute multiple commands at one time. Easy to install, set up and use. Multiple security features include password protection, valid referer URL list, hidden directories, configurable file names. Syslog2 Syslog2 is a realtime parser and event handler for syslogd. An event is a message from some service. It uses a simple plugin system to add event handlers. Syslog2 is written in Perl. A plugin is simply a Perl script which invokes the "register_handler" or "unregister_handler" subroutines. By default, the package uses the included script "default.pl", which logs all messages from the syslog daemon in sorted order. More scripts are available from the homepage.
