"Why Can't I Connect" makes it easier to resolve TCP/IP connection errors. Use it to diagnose connections to common server types and create generic clients and / or servers. A source tar, a 32 bit rpm, a 32 bit deb, and a 32 bit Windows install exe are available. The 32 bit Windows executable runs fine in 64 bit Windows systems. 64 bit Linux systems, however, should compile from source.
