A user-space utility for testing the memory subsystem for faults. It is portable and should compile and work on any 32- or 64-bit Unix-like system. (Yes, even weird, proprietary Unices, and even Mac OS X.) For hardware developers, memtester can be told to test memory starting at a particular physical address as of memtester version 4.1.0. The original source was by Simon Kirby <sim@stormix.com>. The program has been rewritten by Charles Cazabon and many additional tests were added to help catch borderline memory. He also rewrote the original tests (which catch mainly memory bits which are stuck permanently high or low) so that they run approximately an order of magnitude faster.

The Autopsy Forensic Browser is a graphical interface to the command line digital investigation analysis tools in The Sleuth Kit. Together, they can analyze Windows and UNIX disks and file systems (NTFS, FAT, UFS1/2, Ext2/3). As Autopsy is HTML-based, you can connect to the Autopsy server from any platform using an HTML browser. Autopsy provides a "File Manager"-like interface and shows details about deleted data and file system structures. WARNING: The cross-platform version of Autopsy is no longer actively developed. This port is retained mainly to allow users with saved data to migrate to another forensic tool.

reslog resolves IPs in Apache(8) log files. The result can then be analyzed by another program, like Analog. You can think of it as a replacement of the Apache(8) HostNameLookups directive, in the sense that it resolves client IPs altogether once a day. Resolving takes long time. This is mainly caused by resolving: Network packets may be filtered by firewalls; DNS servers may not be correctly configured; may not be up working; may sit in slow network sections; may be old slow machines; may have traffic jam... etc. All these reasons are out of our control.

`skill' is a program which sends signals to processes given any combination of user names, ttys, commands, and pids. `snice' is a program which changes the priority of processes (given the same). It's actually one program which examines argv to determine what action is to be taken on matching processes. It is similar to kill(1) and renice(8), however the command line is completely order independent. There are also verbose, search, and interactive modes of operation. The name `skill' stems from `SuperKILL', but if you use it under `csh', you may discover another reason for calling it `skill' (hint "s!!").

screenFetch is a "Bash Screenshot Information Tool". This handy Bash script can be used to generate one of those nifty terminal theme information + ASCII distribution logos you see in everyone's screenshots nowadays. It will auto-detect your distribution and display an ASCII version of that distribution's logo and some valuable information to the right. There are options to specify no ascii art, colors, taking a screenshot upon displaying info, and even customizing the screenshot command! This script is very easy to add to and can easily be extended.

"Swapd" is a daemon that watches free memory and manages swap files. If free memory drops too low, additional swap files are created. Additionally, if there is too much free memory, swap files are deactivated and disk space may be reclaimed. "Linux swapd" (http://sourceforge.net/projects/swapd/) didn't work very well, but the idea was good. I started making a version that would work and would also be somewhat portable. It currently compiles on Linux and FreeBSD, but requires `libstatgrab' (http://www.i-scream.org/libstatgrab/) to work on platforms that don't have /proc/meminfo (i.e., platforms that aren't Linux).

The LPRng software is an enhanced, extended, and portable implementation of the Berkeley LPR print spooler functionality. While providing the same interface and meeting RFC1179 requirements, the implementation is completely different and provides support for the following features: lightweight (no databases needed) lpr, lpc, and lprm programs; dynamic redirection of print queues; automatic job holding; highly verbose diagnostics; multiple printers serving a single queue; client programs do not need to run SUID root; greatly enhanced security checks; and a greatly improved permission and authorization mechanism.

Tartarus provides a nice wrapper around basic Unix tools such as tar, find and curl (well, that's not that basic) to provide a seamless backup solution, aimed at automatic gathering and backup. It has the ability to do full as well as incremental backups and is published by Stefan Tomanek under the rules of the GPL. Instead of relying on single usage backup scripts or complicated command lines, tartarus reads its configuration from easily manageable configuration files. It can store gathered data in regular files, or upload the backup directly (on the fly) to an FTP server. For more specific usage scenarios, custom methods can also be defined within the config file.

tdir is Yet Another Way To Display Directory Listings. Output is in columnar format with sub-directories listed first, and then a listing of the files ordered by their ending "extension" - typically the characters following the rightmost '.' in the file name (though this can be changed on the command line). tdir supports recursive directory examination. Total output width as well as column width can be set on the command line and tdir will autoformat accordingly. tdir is written in 'python' and requires a reasonably current version of the 'python' environment to be present on the system.
