Script Name 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. load A simple Perl script which monitors system load and if the load is higher than a specified amount, it performs user-defined commands in an attempt to lower the load. Once the load has returned to a normal level (also user-defined), it will perform another set of specified commands to bring the server back to normal. This script also can connect to an Eggdrop bot to announce problems with the server load in real-time. World Wide Backup World Wide Backup is a free script that will allow you to backup your website and even gives you the option to FTP that backup to another server. Requires that your server has Tar (most UNIX/Linux based systems do). For the FTP option, you also will need the Net::FTP module installed on your server (again, most do). The script also can email you when the backup is finished (or if there was an error). Perfect for Cobalt servers. Abax Web Server Status This is a web server status checking script, called using a simple image tag embedded within a web page. It can be setup to check multiple / individual web pages, web servers or domains. If the script finds the web server is serving http requests it will display a 'live' image. Very useful if you want visitors to a gateway / portal page to be able to check which of your mirror web sites are active. In this release I've added security features, this stops the script being abused, Server Status now only requests the first 6000 bytes of a target web page. Other minor issues corrected. NStouch NStouch is a nameserver tool written in Perl and PHP. The perl script monitors all nameservers that are put into the config file nameservers.dat. It will email the admin when the nameserver(s) go down, keep a log, and tell you the % uptime. It also includes a php interface for interacting with the script from the web. This tool can be combined with MRTG to graph output and see the response times.
