通过以太网补丁线实现高速文件传输

Hacker News 上发布的一份技术指南介绍了通过以太网补丁线直接连接两台计算机进行文件传输的方法。1该方案利用 IPv6 地址配置和 socat 工具建立 TCP6 连接，可实现约 900 Mbits/秒的传输速度，相当于每分钟 6.7GB。1

这种点对点直连的以太网传输相比云存储、WiFi 和 USB 存储具有更高的可靠性和速度，且无需依赖本地网络基础设施。1配置过程涉及使用命令为相应网卡添加 IPv6 地址（如 ip address add dev eth0 fd42:dead:beef::1/48），随后通过 socat 工具建立连接实现文件传输。1

A method for transferring files between two computers using a direct Ethernet patch cable connection has been documented, offering significant speed advantages over conventional alternatives.1 By configuring IPv6 addresses and utilizing the socat tool, this approach achieves transfer rates of approximately 900 megabits per second, equivalent to 6.7 gigabytes per minute.1

The technique requires minimal setup: one computer is configured with an IPv6 address using the command ip address add dev eth0 fd42:dead:beef::1/48, after which socat can establish a TCP6 connection to facilitate data transfer.1 This point-to-point connection model eliminates the need for an intermediate local network infrastructure, making it practical for direct machine-to-machine file sharing.1 The direct Ethernet connection demonstrates superior performance and reliability compared to cloud storage, WiFi networks, and USB storage solutions.1
