This is my best stuff of all time.
What is GNS3?
GNS3 is a graphical network simulator that allows simulation of complex networks. To allow complete simulations, GNS3 is strongly linked with:
* Dynamips, the core program that allows Cisco IOS emulation.
* Dynagen, a text-based front-end for Dynamips.
* Qemu, a generic and open source machine emulator and virtualizer.
GNS3 is an excellent complementary tool to real labs for network engineers, administrators and people wanting to pass certifications such as CCNA, CCNP, CCIP, CCIE, JNCIA, JNCIS, and JNCIE.
It can also be used to experiment features of Cisco IOS, Juniper JunOS or to check configurations that need to be deployed later on real routers.
This project is an open source, free program that may be used on multiple operating systems, including Windows, Linux, and MacOS X.
What is Vpcs-0.20a?
Welcome to Virtual PC Simulator, Ver 0.20a.
The VPCS can simulate up to 9 PCs. You can ping/traceroute them, or ping/traceroute the other hosts/routers from the VPCS when you study the Cisco routers in the dynamips. VPCS is not the traditional PC, it is just a program running on the Linux, Windows or OS X (need more testing), and only few network
Commands can be used in it. But VPCS can give you a big hand when you study the Cisco devices in the Dynamips. VPCS can replace the routers or VMware boxes which are used as PCs in the dynamips network.
What is IOSHunter?
IOSHunter is the excellent choice if you want to find suitable IOS image for your router or switch. It browses various ftp servers and web pages to find the requested image. IOSHunter's search engine is multithreaded, so the process of searching is rather fast.
What is PuTTY?
PuTTY is a free terminal emulator that supports SSH and many other protocols. Most users, particularly on Windows, find it very useful for connecting to a Unix or Linux SSH server. PuTTY has a graphical configuration interface with many useful features:
* Storage of connection data for quick reconnection
* Port forwarding
* IPv6 support
* SCP and SFTP support
What is Tftpd32?
Tftpd32 is a free, open source IPv6 ready application which includes DHCP, TFTP, DNS, SNTP and Syslog servers as well as a TFTP client.
The TFTP client and server are fully compatible with TFTP option support (tsize, blocksize and timeout), which allow the maximum performance when transferring the data.
What is Wintabber?
WinTabber - Tab your terminal, shell, browser or favorite application
WinTabber can add tabs to many windows. A tabbed browser, tabbed putty, tabbed terminal or tabbed shell, tabbed anything. Multi tab your windows in seconds. A terminal or shell with tabs work faster and efficiently! Having multiple windows as tabs will give a better overview of your windows than before. Also having multiple ssh sessions by the click of a tab works faster and efficiently.
What is Packet Tracer?
Packet Tracer is a powerful network simulator that can be utilized in training for CCNA and CCNP certification exam by allowing students to create networks with an almost unlimited number of devices and to experience troubleshooting without having to buy real Cisco routers or switches.

What is Cisco SDM?
Cisco SDM is a web-based configuration tool that allows you to configure LAN and WAN interfaces, routing, Network Admission Control (NAC), Network Address Translation (NAT), firewalls, Intrusion Prevention System (IPS), Virtual Private Networks (VPNs), and other features on the router. Cisco SDM 2.1 and later versions can be installed on a PC, or in router flash, disk, or slot memory. Earlier versions of Cisco SDM cannot be installed on PCs, and can be installed in router flash, disk, or slot memory. If you have a router listed in the Hardware Supported section, Cisco SDM is either preinstalled in router memory, or is shipped on a CD with the router.
Cisco SDM Express allows you to give a router a basic LAN, WAN, firewall and NAT configuration. It is installed in router memory.

What is ASDM?
Cisco Adaptive Security Device Manager (ASDM) delivers world-class security management and monitoring services for security appliances through an intuitive, easy-to-use, management interface. Bundled with supported security appliances, the device manager accelerates security appliance deployment with intelligent wizards, robust administration tools, and versatile monitoring services that complement the advanced security and networking features offered by Cisco ASA 5500 series and Cisco PIX 500 series security appliances.
What is Nmap?
Nmap ("Network Mapper") is a free and open source (license) utility for network exploration or security auditing. Many systems and network administrators also find it useful for tasks such as network inventory, managing service upgrade schedules, and monitoring host or service uptime. Nmap uses raw IP packets in novel ways to determine what hosts are available on the network, what services (application name and version) those hosts are offering, what operating systems (and OS versions) they are running, what type of packet filters/firewalls are in use, and dozens of other characteristics. It was designed to rapidly scan large networks, but works fine against single hosts. Nmap runs on all major computer operating systems, and official binary packages are avalable for Linux, Windows, and Mac OS X. In addition to the classic command-line Nmap executable, the Nmap suite includes an advanced GUI and results viewer (Zenmap), a flexible data transfer, redirection, and debugging tool (Ncat), a utility for comparing scan results (Ndiff), and a packet generation and response analysis tool (Nping).
What is POPcon?
POPcon downloads the emails from POP3, POP3-SSL, IMAP and IMAP-SSL mailboxes and distributes them to domino mailboxes according to the recipient information found in the mail headers.
POPcon checks each incoming email with its built-in antivirus scanner. Emails that contain viruses are encapsulated in a warning message and can be diverted to the postmaster. Antivirus signatures are automatically updated daily. POPcon also includes anti-spam measures.
What is Wireshark?
Wireshark is a network packet analyzer. A network packet analyzer will try to capture network packets and tries to display that packet data as detailed as possible.
You could think of a network packet analyzer as a measuring device used to examine what's going on inside a network cable, just like a voltmeter is used by an electrician to examine what's going on inside an electric cable (but at a higher level, of course).
In the past, such tools were either very expensive, proprietary, or both. However, with the advent of Wireshark, all that has changed.
Wireshark is perhaps one of the best open source packet analyzers available today.
What is SecureCRT?
SecureCRT for Windows and Mac provides rock-solid terminal emulation for computing professionals, raising productivity with advanced session management and a host of ways to save time and streamline repetitive tasks.
