Synth is a custom packge repository builder for FreeBSD and DragonFly. It is intended to replace Portmaster, portupgrade, and poudriere for the average user. It is simple to learn (the powerful options are limited in number) and user-friendly, but it is extremely fast due to its parallel building capability. It will "drop-in" on any system as it leverages the stock pkg(8) facilities. All ports are built in a clean environment, so it is finally safe to build ports as needed on a live system. The default profile is the system itself, not a new jail, which can be a valuable feature for some environments. To bring a system up-to-date only requires one command after the ports tree is updated: > synth upgrade-system During the building process, a curses-based display will show the status of all the builders and the entire bulk run process. Synth is intended to be grasped and utilized by novice users within minutes, but offers most of the same powerful features as Poudriere for the power users. Synth requires no preparation; it works immediately upon installation.

Kerberos V5 is an authentication system developed at MIT. This package/port contains the applications which used to be in the MIT Kerberos distribution. Abridged from the User Guide: Under Kerberos, a client sends a request for a ticket to the Key Distribution Center (KDC). The KDC creates a ticket-granting ticket (TGT) for the client, encrypts it using the client's password as the key, and sends the encrypted TGT back to the client. The client then attempts to decrypt the TGT, using its password. If the client successfully decrypts the TGT, it keeps the decrypted TGT, which indicates proof of the client's identity. The TGT permits the client to obtain additional tickets, which give permission for specific services. Since Kerberos negotiates authenticated, and optionally encrypted, communications between two points anywhere on the internet, it provides a layer of security that is not dependent on which side of a firewall either client is on. The Kerberos V5 package is designed to be easy to use. Most of the commands are nearly identical to UNIX network programs you are already used to. Kerberos V5 is a single-sign-on system, which means that you have to type your password only once per session, and Kerberos does the authenticating and encrypting transparently.

Snort is a libpcap-based packet sniffer/logger which can be used as a lightweight network intrusion detection system. It features rules based logging and can perform content searching/matching in addition to being used to detect a variety of other attacks and probes, such as buffer overflows, stealth port scans, CGI attacks, SMB probes, and much more. Snort has a real-time alerting capability, with alerts being sent to syslog, a separate "alert" file, or even to a Windows computer via Samba. Packets are logged in their decoded form to directories which are generated based upon the IP address of the remote peer. This allows Snort to be used as a sort of "poor man's intrusion detection system" if you specify what traffic you want to record and what to let through. For instance, I use it to record traffic of interest to the six computers in my office at work while I'm away on travel or gone for the weekend. It's also nice for debugging network code since it shows you most of the Important Stuff(TM) about your packets (as I see it anyway). The code is pretty easy to modify to provide more complete packet decoding, so feel free to make suggestions.

This script provides functionality for manipulating collections of configuration files which can be organised so as to alter the personality of a system. Initially, the "base" personality is established. This personality contains the "reference" copies of configuration files, and is used when creating new personalities. The files which are currently considered part of the system's personality are those contained in the base personality. A new personality is established by making a copy of the base personality under a new name. Each personality maintains a separate copy of all configuration files under /etc/personality. To install a new personality, the files currently in place are saved back to the current personality as indicated in /etc/personality/current, and the files for the new personality copied into place. The 'select' and 'menu' commands which perform these installations are implemented in such a fashion as to only require the tools available on the root filesystem, so that they may be invoked at the earliest stage during system startup.

Parse::HTTP::UserAgent implements a rules-based parser and tries to identify MSIE, FireFox, Opera, Safari & Chrome first. It then tries to identify Mozilla, Netscape, Robots and the rest will be tried with a generic parser. There is also a structure dumper, useful for debugging. User agent strings are a complete mess since there is no standard format for them. They can be in various formats and can include more or less information depending on the vendor's (or the user's) choice. Also, it is not dependable since it is some arbitrary identification string. Any user agent can fake another. So, why deal with such a useless mess? You may want to see the choice of your visitors and can get some reliable data (even if some are fake) and generate some nice charts out of them or just want to send an HttpOnly cookie if the user agent seems to support it (and send a normal one if this is not the case). However, browser sniffing for client-side coding is considered a bad habit.

From the website: What is PHP Surveyor? PHP Surveyor is a set of PHP scripts that interact with MySQL to develop surveys, publish surveys and collect responses to surveys. Once a survey has been created it can be published as an online survey (displayed as single questions, group by group or all in one page) or you can use a dataentry system for administration of paper-based versions of the survey. PHP Surveyor can produced 'branching' surveys (set conditions on whether individual questions will display), can vary the look and feel of your survey through a templating system, and can provide basic statistical analysis of your survey results. PHP Surveyor includes the capacity to generate individualised 'tokens', so if you have a list of people you want to invite to participate in a survey you can issue each one with a token, and they will be able to access the survey using that token. This allows for quite good quality control of your surveys.

Expect::Simple is a wrapper around the Expect module which should suffice for simple applications. It hides most of the Expect machinery; the Expect object is available for tweaking if need be. Generally, one starts by creating an Expect::Simple object using new. This will start up the target program, and will wait until one of the specified prompts is output by the target. At that point the caller should send() commands to the program; the results are available via the before, after, match_str, and match_idx methods. Since Expect simulates a terminal, there will be extra \r characters at the end of each line in the result (on UNIX at least). This is easily fixed: ($res = $obj->before) =~ tr/\r//d; @lines = split( "\n", $res ); This is not done automatically. Exceptions will be thrown on error (match with /Expect::Simple/). Errors from Expect are available via the error_expect method. More human readable errors are available via the error method. The connection is automatically broken (by sending the specified disconnect command to the target) when the Expect::Simple object is destroyed.

The Log::Agent module provides an abstract layer for logging and tracing, which is independent from the actual method used to physically perform those activities. It acts as an agent (hence the name) that collects the requests and delegates processing to a sublayer: the logging driver. The Log::Agent module is meant to be used in all reusable components, since they cannot know in advance how the application which ends up using them will perform its logging activities: either by emitting messages on stdout and errors on stderr, or by directing messages to log files, or by using syslog(3). The logging interface is common for all the logging drivers, and is therefore the result of a compromise between many logging schemes: any information given at this level must be either handled by all drivers, or may be ignored depending on the application's final choice. WARNING: THIS INTERFACE IS STILL SOMEWHAT ALPHA AND COULD STILL CHANGE DEPENDING ON THE FEEDBACK THE AUTHOR RECEIVES, WITHOUT ANY BACKWARD COMPATIBILITY ASSURANCE.

DeuTex is a tool to work with WAD files for Doom, Heretic, Hexen, and Strife. It can be used to extract the lumps from a WAD and save them as individual files. Conversely, it can also build a WAD from separate files. When extracting a lump to a file, it does not just copy the raw data, it converts it to an appropriate format (such as PPM for graphics, Sun audio for samples, etc.). Conversely, when it reads files for inclusion in PWADs, it does the necessary conversions (for example, from PPM to Doom picture format). In addition, DeuTex has functions such as merging WADs, etc. If you're doing any WAD hacking beyond level editing, DeuTex is a must.

Bonnie++ is a benchmark suite that is aimed at performing a number of simple tests of hard drive and file system performance. Then you can decide which test is important and decide how to compare different systems after running it. I have no plans to ever have it produce a single number, because I don't think that a single number can be useful when comparing such things. The main program tests database type access to a single file (or a set of files if you wish to test more than 1G of storage), and it tests creation, reading, and deleting of small files which can simulate the usage of programs such as Squid, INN, or Maildir format email.
