Angry IP Scanner

Angry IP scanner is a very fast IP scanner and port scanner. It can scan IP addresses in any range as well as any their ports. Its binary file size is very small compared to other IP or port scanners. Angry IP scanner simply pings each IP address to check if it's alive, then optionally it is resolving its hostname, determines the MAC address, scans ports, etc. The amount of gathered data about each host can be extended with the available plugins.

It also has additional features, like NetBIOS information (computer name, workgroup name, and currently logged in Windows user), favorite IP address ranges, customizable openers, etc.

Scanning results can be saved to CSV, TXT, HTML, XML or IP-Port list file, can be used as a command-line utility in a batch file, etc. With help of plugins, Angry IP Scanner can gather any information about scanned IPs. Anybody who can write code is able to write plugins and extend functionality of Angry IP Scanner.

In order to increase scanning speed, it uses multithreaded approach: a separate threads is created for each scanned IP address.

It is free and open-source software, so use it at your own risk.

This program is mostly useful for network administrators to monitor and manage their networks.

Synergy :: Sourceforge.net

synergy: [noun] a mutually advantageous conjunction of distinct elements

Synergy lets you easily share a single mouse and keyboard between multiple computers with different operating systems, each with its own display, without special hardware. It's intended for users with multiple computers on their desk since each system uses its own monitor(s).

Redirecting the mouse and keyboard is as simple as moving the mouse off the edge of your screen. Synergy also merges the clipboards of all the systems into one, allowing cut-and-paste between systems. Furthermore, it synchronizes screen savers so they all start and stop together.

The real beauty of Synergy though, is that the machines sharing a single keyboard/mouse can be running virtually any operating system. Windows, Linux, OS X, Solaris - they all work seamlessly!

Hamachi is fast, secure and simple. Its core version is also free. "

KeePass Password Safe

Today you need to remember many passwords. You need a password for the Windows network logon, your e-mail account, your homepage's ftp password, online passwords (like SourceForge member account), etc. etc. etc. The list is endless. Also, you should use different passwords for each account. Because if you use only one password everywhere and someone gets this password you have a problem... A serious problem. The thief would have access to your e-mail account, homepage, etc. Unimaginable.

KeePass is a free/open-source password manager or safe which helps you to manage your passwords in a secure way. You can put all your passwords in one database, which is locked with one master key or a key-disk. So you only have to remember one single master password or insert the key-disk to unlock the whole database. The databases are encrypted using the best and most secure encryption algorithms currently known (AES and Twofish). For more information, see the features page.

Console is a Windows console-window enhancement. It was inspired by eConsole. Console features include configurable font, color, size, background image and transparency (on Win2000 and later) Link

MP3 Ripper - FreeRIP

FreeRIP
FreeRip is a freeware application that lets you save audio CD tracks to Wav or MP3 or Ogg Vorbis audio files. FreeRIP is also an audio file converter since it can convert and encode from WMA, MP3, Ogg Vorbis, Wav files to Ogg Vorbis, MP3 or Wav.

FreeRIP is a CD ripper, this means that it can record digital audio tracks directly from audio CD to files on your hard drive (this process is known as "ripping"). You can save tracks as CD quality WAV files or encode them to Ogg Vorbis or MP3 compressed audio format.

freedb CD database, and ID3 Tagging (Version 1 and 2) are supported. FreeRIP automatically downloads album and song titles from freedb Internet databases and stores them in the MP3 and Ogg Vorbis files themselves.

There are even tutorials available in (currently) four languages.

tcptraceroute

DAG: tcptraceroute RPM packages for Red Hat/Fedora
tcptraceroute is a traceroute implementation using TCP packets.

The more traditional traceroute sends out either UDP or ICMP ECHO packets with a TTL of one, and increments the TTL until the destination has been reached. By printing the gateways that generate ICMP time exceeded messages along the way, it is able to determine the path packets are taking to reach the destination.

The problem is that with the widespread use of firewalls on the modern Internet, many of the packets that traceroute sends out end up being filtered, making it impossible to completely trace the path to the destination. However, in many cases, these firewalls will permit inbound TCP packets to specific ports that hosts sitting behind the firewall are listening for connections on. By sending out TCP SYN packets instead of UDP or ICMP ECHO packets, tcptraceroute is able to bypass the most common firewall filters.

Mount .iso files under windows XP

This free program for Windows XP lets you create a virtual CD drive on your hard disk. winxpvirtualcdcontrolpanel_21.exe

For anyone unfamiliar with the terms 'virtual CD' or 'CD emulator', they mean that you can copy the entire contents of a CD-ROM to your hard disk and run the programs or access the files without the original CD in your machine. This can make files more accessible, faster and more convenient. Given the speed and size of today's hard drives, you could easily fit a number of CDs onto your hard drive without noticing the difference. Assuming you had 30 full CDs, these would take around 20GB on a hard drive and all will be accessible after a few clicks of a mouse.

Why would we want to do this?

One reason is convenience, imagine needing several (handfuls of) discs that you need to carry with you. Using a virtual CD, you can simply keep an image of the disc on your hard drive and access it with a drive letter as needed - no disc. In my laptop, the secondary battery takes place of my CD/DVD drive but I can still access the files I need through the Virutal CD drive.

A second reason is speed. Hard drives are about 10 times faster than a CD, plus you can instantly access the file instead of grabbing the CD case, inserting the CD and awaiting for the contents to load. It's true, you could try copying the files over to the hard drive, but this can get messy, plus some programs require a CD to be loaded in order to run. This virtual CD program 'pretends' it is a CD drive (even though the files are on your hard drive), so your programs will run as normal.

Note: This tool only works with ISO images - not BIN/CUE image sets.

THIS TOOL IS UNSUPPORT BY MICROSOFT PRODUCT SUPPORT SERVICES


System Requirements
===================
- Windows XP Home or Windows XP Professional

Installation instructions
=========================
1. Copy VCdRom.sys to your %systemroot%\system32\drivers folder.
2. Execute VCdControlTool.exe
3. Click "Driver control"
4. If the "Install Driver" button is available, click it. Navigate to the %systemroot%\system32\drivers folder, select VCdRom.sys, and click Open.
5. Click "Start"
6. Click OK
7. Click "Add Drive" to add a drive to the drive list. Ensure that the drive added is not a local drive. If it is, continue to click "Add Drive" until an unused drive letter is available.
8. Select an unused drive letter from the drive list and click "Mount".
9. Navigate to the image file, select it, and click "OK". UNC naming conventions should not be used, however mapped network drives should be OK.

You may now use the drive letter as if it were a local CD-ROM device. When you are finished you may unmount, stop, and remove the driver from memory using the driver control.
