GoKawiilGuide details manual Ethernet cable method for fast local file transfers
A technical note explains how to move large files directly between two computers by connecting them with a standard Ethernet patch cable, manually assigning IPv6 addresses to each machine's interface, and piping data through tools like socat and dd. The author reports this setup can reach roughly 900 Mbits per second on ordinary hardware, translating to about 6.7 GB per minute, far outpacing USB drives or cloud uploads for nearby machines.
