Free twisted sister software for linux

Twisted Storage is an application that will take your data and manage it for you, just like a file system. But Twisted Storage goes way beyond what a normal file system does.
What types of "objects" are stored in Twisted Storage : just regular files. The data stored in the system is expected to be fixed content, meaning it doesnt change at all. If you read the data back, change it, and store it, it is considered a different file. There are plenty of examples of fixed content data : emails you received, movies or mp3 files you made or own, documents you wrote, etc. In fact it is estimated that 80% of the data you have on your computer is fixed, reference data.
Your Twisted Storage system can start out small - a single computer with a few disk drives. When you need more storage you can add more disk drives and more computers. But it has been designed to store petabytes worth of data without requiring any special hardware. For example storing a petabyte worth of data, using the biggest disk drives available today (500 GB), would require 2000 disk drives. To overcome the need of special hardware, Twisted Storage is a scalable, distributed system using ordinary commodity computers. Even so that petabyte of data would require 500 computers networked together and that requires special handling.
Twisted Storage has a few features you wont find in any file system. For example once a file is added to the Twisted Storage repository it can be written in multiple locations simultaneously. The system has been designed to be compliant with Sarbanes-Oxley Act: when an object is added to the repository you can no longer delete it and the integrity of the contents are guaranteed. In addition any access to the object is recorded.
Main features:
Scalable to thousands of servers and multiple petabytes of data.
- Regardless of how much data you want to store,Twisted Storage is designed to handle it. The system can grow from one computer and a few disks to hundreds of systems and thousands of disk drivers.
Automatic data recovery without human intervention.
- Twisted Storage doesnt require backup/restore software or procedures. All data written to the system is recorded in multiple locations.
No special disaster recover procedures.
- So long as you have your systems in physically different locations and you have instructed the software to write the multiple copies to those systems, you have no-hassle disaster recover. If one of the sites goes down, the system will retrieve any data from the other systems. Additionally, once the disaster site is up and running, the system will automatically restore the data to the it.
Simplified configuration.
- To ease management of the system, you can change any one systems configuration and have it ripple through out the system.

Twisted Web includes an HTTP/1.0 protocol implementation for both servers and clients. Twisted Web also includes a resource framework for implementing rich, dynamic web applications. It includes support for authentication either via HTTP AUTH, session URLs, or session cookies.
It supports CGIs and a custom PB-based distribution mechanism for serving content from separate, persistent processes. It includes SOAP and XML-RPC support for both clients and servers. It also makes it particularly easy to deploy new servers with novel or ephemeral use-cases, often with only a single short command.
Enhancements:
- This release adds HTTP Basic auth support for XML-RPC clients, and fixes several date, time, and If-Modified-Since header parsing corner-cases.
- Various performance improvements have been made, and support for CGIs broken in a few specific ways has been improved.

Big Sister network monitor is a real time system and network health monitoring application.

Twisted Words library provides implementations of a handful of IM protocols, including IRC, MSNP8, OSCAR, TOC, and Jabber.

Twisted Words provides two separate high-level end-user features:

a multiprotocol instant messaging server
a multiprotocol instant messaging client

These are both still in the early stages of development and are not expected to work flawlessly in all configurations, however each is quite usable for a limited set of functionality. A Twisted Words server can be created with just a couple commands:

$ mktap words --irc-port 6667 --pb-port 8787 --passwd password_file --group somegroup
$ twistd -f words.tap

The Twisted Words client is named im and is usable as an IRC client, and possibly an AIM client (depending on the phase of the moon).

Low Level Functionality:

Twisted Words also includes:

Low-level protocol implementations of OSCAR (AIM and ICQ), IRC, MSN, TOC (AIM).
Jabber libraries.

Prototypes of chat server and client frameworks built on top of the protocols.

Twisted Packager II (TP2) is a package manager that aims to make live easy - for end users and also developers. In some respects it is similar to Autopackage - it does not intend to replace the "system packaging tool" but instead will sit alongside it to allow application developers an easy way to package software; and system administrators an easy way to install [or remove!] such software.
TP2 excels at handling generic software - and allows a "source" type package [such as itself!] to be installed across multiple architectures and operating systems using the same package.
TP2 is cross-platform; it is currently in use on Solaris, Linux and HP-UX. Soon the intention is validate it also for BSD and AIX.
TP2 is flexible. It supports dependency management, package verification, preview installation and removal, and audit logs all activity.
TP2 is powerful. It supports "namespaces" which allows the same packages to be installed into different areas on the same machine. Non-root users can be given areas which they can manage independently.
Enhancements:
- Initial public announcement, though the software has been in use in several environments for over 12 months.

ASK is a spam killer. This program (Active Spam Killer, or ASK for short) takes an "Active" approach in solving the problem: Everytime an email is received, a message is sent back to the sender asking for confirmation. If that sender does not confirm the message, it remains queued for delivery. If the sender confirms, the message is delivered and removed from the queue. The "confirmed" senders will be added to your "whitelist" and will never be sent another confirmation. Messages from these emails will always be delivered immediately . You can also specify an "ignorelist" for emails that should be always ignored and a "blacklist" that will cause a nastygram to be sent back to the sender everytime an email is received.

There are many traditional approaches to avoiding spam. The most common approach is based on "content-filtering": a program that attempts to classify incoming mails based on their content. This works partially, but in reality, its somewhat easy to find ways to avoid it.

ASK takes advantage of the fact that most spammers use invalid or fake "From:" address in their messages. When a new message arrives and the sender is unknown, ASK sends a "confirmation message" back, informing the sender that the original message has been queued, pending confirmation. When the sender confirms (a simple reply), ASK delivers the original message and adds the sender to a "whitelist". Further messages from this sender will be immediately delivered. It is also possible to ignore messages based on specific criteria, like senders email, subject and so on.

The goal of ASK is to block Spam mail before it is delivered to your mailbox. As we know, filtering alone is not effective since many times Spam mail contains no detectable elements.

ASK should be invoked from .forward (or .procmailrc if you are using procmail). The incoming message should be piped to ASK, which will be in charge of doing the actual delivery.

When ASK receives an email, if first checks the email address against your "ignorelist". If the address is listed there, its ignored completely. Then, the message is checked against your "blacklist". If its there, a nastygram is sent back to the sender with something like "Please stop sending me emails" in the Subject line.

The real fun happens when an email comes from an unknown user (i.e, someone not in any of your lists). In this case, ASK calculates the MD5 checksum of the message + a secret MD5 key (configured during installation time). This number is sent as part of a "confirmation message" back to the user. If the user replies to it, the confirmation number (in the subject) is recognized, the message is dequeued and delivered. If the user does not reply, the message remains queued until its removed.

The program has some intelligence to deal with specific cases. For instance, if a mail is sent to a non-existing user, the error message from mailer-daemon is ignored. This avoids seeing lots of "invalid user" messages in your inbox.

Another interesting "twist" is that messages coming from your own email address are never trusted. If the spammer knows your address he could easily fake your own address as the From: line. Messages coming from you will be identified by a "mailkey", a piece of string you always put on your message by default (maybe a piece of your own signature). Note that this has the added side-effect of allowing any messages coming in reply to a message you sent to someone (as long as that person keeps your "mailkey" in its quoted reply, a practice common these days).

The program never deletes any messages. For instance, if you send yourself a message without your mailkey (a possible Spam), it will be saved in a "Junk" mailfolder (you can specify this folder during the configuration).

Pxytest is a command line utility to test a host for open proxies that are vulnerable to spammer abuse.

Unsecured proxies currently are the most significant conduit of junk email. This is a particularly vexing problem, because open proxies, unlike open mail relays, hide the origin of the spam, making it impossible to trace. This utility tests a host to see if it is vulnerable to such abuse.

The following types of unsecured proxies are detected: http-connect, http-post socks4, socks5, wingate, telnet and cisco. See the manual page for descriptions of these proxy types.

If you find this utility useful, you also may be interested in its sister utility, the rlytest open relay tester.

Timewave is a space shooter in which the player can alter the flow of time.

Its a top-down space shooter with a twist: your ship has a limited ability to control time. Holding one button causes the game to run at double speed and builds up a meter on-screen. Another button expends the bar but causes the game to play at half speed, affording the player some extra maneuvering room in times of need.

The game will features fix levels of increasing difficulty, followed by a battle against a final boss. It saves high scores and feature a full soundtrack and an array of explosion and gunshot noises.
