任意2台电脑间安全高效传输文件

安利一个最近喜欢的文件传输工具

• https://github.com/schollz/croc
• https://schollz.com/tinker/croc6/
• 安全高效 目前我个人一直在使用

所有电脑安装croc

建立自己的文件互传中继

• 挑选1台由公网IP的服务器做中继 记录自己的ip

nohup croc relay >croc_relay.log 2>&1 &
ubuntu@VM-0-7-ubuntu:~/shell$ cat croc_relay.log
nohup: ignoring input

如果没有公网ip也可以用下面我自己的服务器体验
