ramlog acts as a system daemon that maintains log files in memory instead of hard disk while the system is running. On startup, it creates a ramdisk, copies files from /var/log into the ramdisk, and mounts the ramdisk as /var/log. All logs after that will be updated on the ramdisk. When shutting down or restarting the service, it saves log files back to hard disk. This service drastically reduces the frequency of hard disk usage, which can be useful when the system runs on battery or uses flash memory instead of a hard disk.
Vee is a command-line blog tool that is very portable across Unix systems. It provides an interactive as well as a batch interface to maintain a log of entries. Formatting is done using a module architecture that allows a high degree of customization. There are minimal flags and no set up is required.
Logsend is a Unix daemon for email notification of log file changes, having 3 different backends. It watches the log files and periodically mails you the additions (being able to filter them). Logsend comes with a dialog-based configuration tool, as well as a live monitor that allows the users to watch the changes in real time.
log4sh is a logging framework for shell scripts that works similar to the other wonderful logging products available from the Apache Software Foundation (e.g. log4j, log4perl). Although not as powerful as the others, it can make the task of adding advanced logging to a shell script easier, and has much more power than just using simple "echo" commands throughout. In addition, it can be configured from a properties file so that scripts in a production environment do not need to be altered to change the amount of logging they produce.
Unix Mobile Agents is a generic, flexible, easy to use mobile agent architecture implemented in a set of bash scripts. This design is made to be trivial to deploy and setup. Agents can be configured to traverse the network in sorted order, in user defined order, or as a random walk. They can also run in a repeated loop, or in a single pass through the network. Connections are made via public-key SSH authentication, and the screen utility is used to allow agents to run without requiring terminals.
epto is a small library and framework for industrial strength shell script programming with sh. It features convenient error handling, tracing, logging, option handling, documentation template, process level transaction safety (sort of), and more. If one is used to shell programming, it takes less than five minutes of learning to start using it (see the crash course in the README file).
The mysqlard daemon collects MySQL performance data in a round robin database using rrdtool. rrdtool stores the data in a very compact way that will not expand over time, and it presents useful graphs by processing the data to enforce a certain data density. The main goal of the package is to help the database system administrator in tuning the system for maximum performance. The package also contains example graphing, cron, and PHP scripts.
fwsnort translates snort rules into an equivalent iptables ruleset. By making use of the iptables string match module, fwsnort can detect application layer signatures which exist in many snort rules. fwsnort adds a --hex-string option to iptables, which allows snort rules that contain hex characters to be input directly into iptables rulesets without modification. In addition, fwsnort makes use of the IPTables::Parse Perl module in order to (optionally) restrict the snort rule translation to only those rules that specify traffic that could potentially be allowed through an existing iptables policy.
