TCP Handshake Connection Tester

TCP Handshake Connection Tester is a super handy tool made for developers and network admins. It helps you check if a TCP connection is working well, fast, and complete. Basically, it makes sure the standard 3-way handshake is done right when a TCP connection is set up. This way, developers can see how their application deals with this protocol.

Easy to Use and Portable

No need to deal with long setup processes here! Since this app is portable, you just double-click the executable file and boom – it’s ready to go. Just don’t forget to read and accept the product’s terms first. And because it's portable, you can run it straight from a USB drive without leaving any traces on the computer.

Straightforward Interface

The interface is simple – everything you need is right there in one window; no extra menus cluttering things up. To kick off your analysis of the TCP connection, you’ll fill in a couple of fields: the IP address of the target host and its TCP port number. After that, you’re good to go!

How It Works

Once you connect to your target host, the app will pull up a list of network interfaces with unicast IP addresses that make a TCP connection on that selected port number. It checks if that all-important 3-way handshake completes for each connection.

Check Connection Speed

The tool first sees if the target host can be reached using the version of IP your network interface uses—both IPv4 and IPv6 work here! If it’s reachable, it measures how long it takes for that initial connection to finish. This helps developers and admins understand how well an application handles TCP connections instead of just using ping to get an ICMP response time.

Error Checking Made Easy

Network managers can also use this app to spot errors in TCP data packet transmissions. The TCP Handshake Connection Tester shows stats about received, discarded, and outgoing packets with errors.

A Tool for Professionals

This tool is pretty straightforward but having some networking background helps you get the most out of it. Whether you're a software developer or a network admin, this app gives valuable insights into testing TCP connections made by specific applications.
