wtch periodically runs a shell command COMMAND and watches its output. When it changes it runs shell command ACTION. More precisely, it runs ACTION when a specified event occurs. The event can be a change of COMMAND's output, a change matching a certain pattern, or its negation, output equal to some previous output, etc. The output pattern defining an event is set by the --pattern option. By default, it simply detects any COMMAND output change.
my-swatch pretends to be an implementation of msyslog and swatch together. What it pretends to accomplish is put all together, to log events to a remote database (like msyslog), and to awake triggers (like swatch). When a certain condition occurs you can be notified by email and awake certain events, like play a sound. You can also log the event to a remote database and use a Web browser to surf through the logs.
BBStatus is an IP accounting package and an SNMP and IP monitoring tool for Linux. It collects, summarizes, and displays the values from its database. It can be used for IP accounting (allows you to design various kinds of accounting filters), SNMP monitoring (collects data making SNMP requests), ICMP monitoring (stores and summarizes values like min, avg, max reply time, and packet loss), and client traffic filtering (using various types of filters). It also provides user based access so that every user can log in and visualize various data (depending on access rights). It requires PostgreSQL, Apache with mod_auth_pgsql, Perl(Net::SNMP), and RRDTool.
The Bait and Switch Honeypot System combines the snort Intrusion Detection System (IDS) with honeypot technology to create a system that reacts to hostile intrusion attempts by marking and then redirecting all "bad" traffic to a honeypot that partially mirrors your production system. Once switched, the would-be hacker is unknowingly attacking your honeypot instead of the real data, while your clients and/or users are still safely accessing the real system. Life goes on, your data is safe, and you get to learn about the bad guy as an added benefit. It works with Snort 1.9.0, 1.9.1, and 2.0.2.
