TCP Connection Tester v1.5.2.0

Check for completion of the standard TCP 3-way handshake between a local interface IP address and a target host. TCPConTest also lets you check the selected network interface for IP packet errors.

Application purpose: After accepting the |Product terms of use and legal notice|, TCP Connection Tester • IPv4 and IPv6© can be run on any computer that meets the minimum system requirements. This application is portable. No installation is needed. TCPConTest checks for completion of the standard TCP 3-way handshake (SYN,SYN+ACK,ACK) on a specific port number between a local network interface's unicast IP address you select and a target host. If the target host is accessible over the IP version in use by your selected source interface & endpoint, TCPConTest measures the time elapsed from beginning to end of this initial connection setup sequence then returns that value to the "Time to connect :" line shown in the test results. This value gives you an idea of current throughput latency for a specific application protocol port number on the network or network segment between your source and target. A test of this sort can better indicate an application's protocol handling at the network layer instead of simply pinging a target host and getting the ICMP response time.

Overview: You may import my self-signed certificate, attached to this application, into your computer's certificate store. It verifies code authenticity and safety. Digital signature Serial number: 6ed008241d6e629445ac34c3d826f560, Thumbprint: 254b4a1c38430d09b99d47f1514e601f6dd4bf5e. To start the connection test, first return network interfaces with unicast IP addresses by clicking the network button at the top of the application. You'll only need to return the interface list once when you start. Next, select an interesting network interface from the list, provide a target Hostname or IP address, a target TCP port number then click the 'Start' button to try and connect. The results are then returned. Built-in contextmenus permit you to copy the results to the Windows® clipboard or check the selected network interface for IP packet errors.

Clicking the [?] button above the connection test's 'start' button displays this screen, the 'About TCPConTest & User's Guide' information screen.

To use, simply run the file. No installation needed.

1) First, return a list of IP-enabled network interfaces which have unicast addresses on your computer. Clicking the button in the top left corner of the application will retrieve a new, updated list of available network interfaces each time you click it. The output is displayed under • Available local network interfaces •. You can sort the rows in the list of network interfaces (ascending and descending) by clicking the desired column header.

2) Before trying to start a TCP connection test on a target host, make sure you select the network interface with the unicast IP address that you're interested in from the list. When you select an entry, the interface's speed, or link speed, will be shown just above the list. This speed in bits-per-second (bps) indicates bandwidth available between the selected interface on your computer and the router. If the selected interface is auto-sensing ~ auto-negotiaing, you might notice that this speed can vary between the times you select the interface for testing. This variation in speed over time can often be greater on wireless network interfaces. Higher decreases in this number can indicate periods where more hosts are competing for available network bandwidth. Note: A disconnected interface cannot be tested.

3) Before trying to start a TCP connection test on a target host, provide the name or IP address of the target host. If you are identifying the target by an IP address, TCPConTest will accept both IPv4 or IPv6 formatted addresses.

4) Before trying to start a TCP connection test on a target host, provide the destination TCP port number that you want to try to connect to on the target. An integer port number in the standard range ε[1,65535] ~ between 1 and 65535 inclusive, will be accepted by this application.

5) When you've selected a connected network interface and IP address, provided a target host and target TCP port number, click the 'Start' button to test for completion of the TCP 3-way handshake sequence between the selected source and target. If the test can be carried out in the context of the paramaters you provide, the application's status message will flash that is it working while it is trying to connect. The working time should generally be brief if a test passes. The test results - pass or fail - are returned to the result output window when it completes.

6) After a connection test completes, the result is returned to the window in the top, right corner of the application UI. The output consists of the following parts:

Target host: The target host you provided for the test
Time of this test: The system time when the attempt to connect to the target host begins. The time's display format is yyyy-MM-dd
• TCP connection test result: PASS or FAIL •
Source IP endpoint: The unicast IP address configured on the source network interface you selected along with the source TCP port assigned by the system
Target IP endpoint: The IP address of the target host and the target TCP port number. When supplying a target host-by-name, this will return the name you provided and
not the IP address when name resolution of the target host fails or if a response is not received from the target TCP port. Keep in mind that one possible
reason name resolution can fail is when there is a protocol version mismatch between the source endpoint and the target endpoint. For example, if you
select an IPv6 address on a source interface and the remote network doesn't resolve the target name you specify to an IPv6 address although, say, it
resolves the target name to an IPv4 address. The reverse would also generate a name resolution error, if your source address is IPv4 and the remote
network resolves the host name to only an IPv6 address.
Time to connect: The amount of time elapsed, in milliseconds (ms), for the standard TCP 3-way handshake (SYN,SYN+ACK,ACK) to begin and complete.

7) Copy the TCP connection test result to the Windows® clipboard by selecting this contextmenu command. The result data can then be pasted from the clipboard into another application.

8) Choose this contextmenu command to return a summary of packet error counts from the selected network interface. This can help with quickly identifying if the interface is receiving unusable or malformed packets from remote hosts or if it is constructing incorrect outbound packets. If the interface is reporting outgoing packet problems then it might be caused by improperly functioning interface hardware or driver, or a problem with an application(s) network code for example.
