我已经使用无密码登录ssh至少两年了，但我已经很久没有因为ssh任何原因需要登录我的笔记本电脑了。所以当我发现它不再有效时，我感到很震惊！
我的公钥 ( id_rsa.pub) 仍像它应该的那样在我的authorized_keys文件中，但不知何故，我的系统不再接受它。此外，当我使用 创建新密钥并将ssh-keygen其添加到时authorized keys，新密钥也不起作用。我的文件夹中的所有文件.ssh都有600权限，.ssh文件夹本身也有700权限。
有人知道为什么会发生这种情况吗？我正在运行 macOS Sierra (10.12.2)。
下面是一些调试输出，为了简洁起见，略作了编辑：
09:38 [mchenja .ssh]$ diff -s id_rsa.pub authorized_keys
Files id_rsa.pub and authorized_keys are identical
09:39 [mchenja .ssh]$ ssh -v localhost
.
