Guy’s diary entry “Linux LOLBins Applications Available in Windows” reminded me of another Linux tool that is available on Windows: the ancient finger command.
Here is an example with weather info for the North Pole:
Communication takes place over TCP. Destination port is 79.
The finger.exe command sends the string before the @ sign to the host specified after the @ sign.
finger.exe is not proxy aware, and port 79 is hardcoded inside the finger.exe executable. Not as a number, but as a protocol name (finger) that is defined in the services list (%SystemRoot%system32driversetcservices);
