Why Can't I Connect?

“Why Can't I Connect?” makes it easy to diagnose TCP/IP connection problems. It traces through all steps of the process and gives error codes, descriptions, and possible solutions for all TCP/IP errors. Language support for Chinese (simplified character set), English, French, German, Hindi, Portuguese, and Spanish.

There are separate selections for application language and trace language. This allows a user to run the application in their native language while creating the trace in the native language of the technician researching the problem. For example, application language: English, trace language: Portuguese.

Connect to common servers:

Create a generic client or server

A generic client can connect to any type of server given the right server name / IP and port.

Create a generic server to mimic a server on any port (if available.)

Use the advanced menu options to step through the entire socket process (Bind, Connect / Listen, Send, Shutdown, Close).

You may send text or the contents of files on generic, advanced, and bridged sockets.


Bridging allows you to insert “Why Can't I Connect?” between an existing client and server. You may then trace / analyze / diagnose the conversation between the two.

Open Multiple Servers

Open servers (listening sockets) across a range of ports.

Resolve an IP address to a name or a name to an IP address.

Tracing is in both hexadecimal and ASCII. It may be set to the screen and / or a log file. The amount of tracing may be set to 'All', 'Headers And Errors Only', 'Errors Only', or 'None'.


I've tested on Fedora and Ubuntu Linux. Windows XP, Vista, and Windows 7. I am releasing a source tar, 32 bit rpm, deb, and Windows install exe. The 32 bit Windows executable runs fine in 64 bit Windows systems. 64 bit Linux systems, however, should compile from source.


wxWidgets 2.8.x is required to build. Once statically linked, there are no special requirements.

Sorry, I currently don't own a Mac to develop on. I'm looking for a used one at a reasonable price. Once found, I'll go ahead and make a Mac release.
