ssh-keygen/ssh-keygen.exe三台机器：A（Ubuntu），B（Windows）和C（Ubuntu）我在A和B上运行过。
~/.ssh/id_rsa.pub来自 A 和 B 的 都 活得 很好~/.ssh/authorized_keys。
当我从计算机 A 运行时ssh user@C，无需密码即可顺利登录。
然而当我ssh user@C从 BI 中跑出来时总是提示输入密码。
我看过很多建议整理权限的帖子。因为 A->C 有效，所以我的权限应该没问题。但是 B->C 无效。
从 B 运行 ssh -v user@C 时的输出
PS C:\Users\{{username_on_B}}> ssh -v {{username_on_C}}@{{IP OF C}}
