PortMarshaller is a software-based TCP/IP port forwarder and network administration service. The software accepts connections on a particular TCP port, and establishes connections to a different TCP port to fulfill requests. Administrative web interface allows the monitoring of connection and data transfer statistics. New access control lists allow the filtering of incoming connections.

SBridge connects two TCP/IP servers together creating a "bridge" for the data transfer between them. SBridge can be used to connect TCP/IP servers on the same machine or across any accessible network. SBridge can even be located on a third machine, transparently connecting two application servers for logging communications between them.

Tansu TCP (TT) is a TCP trace utility which listens on a local port and then forwards tcp packets
to another server. You can see and save binary / text data to a file or you can load binary data from a file.

TansuTCP is free to use.

See which ports belong to which programs! Port Explorer shows all the open ports on your system and what programs own them. Along with this ability it also has many tools including a packet sniffer, bandwidth throttling and country detection to name just a few. Port Explorer has an intuitive GUI that allows you to quickly see all your network activity, and thanks to its ease of use is allowing people everywhere to do advanced network activities.

TCP Spy captures and displays all socket calls that an application makes and the data that is sent and received on the application's sockets. TCP Spy will work with any type of application.

TCP Spy can be used by a developer to debug socket communication problems with an application or by anyone who is curious about what socket calls an application is making, including what it is communicating with and the data it is passing.

TCP Viewer captures and displays all data that is transferred between client processes and a server process communicating through TCP/IP. The processes can be running on the same machine or different machines located anywhere on a network or the Internet. TCP Viewer can run on a machine different than the machine(s) that the processes are running on. An example of a client and server is a web browser and web server.

Is Spyware and/or Adware messing up your internet connection after you have uninstalled it?

Has your internet connection slowed down and you just don't know why?

This is the only offered solution which can provide this functionallity, this component extract all MX records of certain doman. MX record is the address of email server.

Without this component, you have to get the records manually using nslookup utility, or using some free web service like zonedit, put you cannot integrate it with your code.

Socket Workbench is the definitive tool for analysing socket communications that underlie the Internet and several types of inter-process communication. Configure Socket Workbench to be a socket client (like a web browser or e-mail client) or a socket server with ease. You can send data through a socket and analyse that data that has been received.

Proxy Workbench is a unique proxy server ideal for developers, trainers and security experts that displays its data in real-time. You can actually see the data flowing between your e-mail client and the e-mail server, web browser and web server or even analyse FTP in both Passive and Active modes. In addition, the 'pass through' protocol handler enables analysis of protocols where the server does not readily change.
