Won’t every pool package have network librairies anyway to handle ranges distribution ?
Probably yes, but I don’t have anything similar in my Git
What should I do if I only have an .EXE file?
To work completely offline, or to use Wireshark to monitor network activity. Another option is to use the decompiler explorer available at

The best option is to compile each application yourself, including the entire (Linux) system from scratch.
