当我尝试在 Windows 机器上的 cygwin sshd 服务器中设置无密码 ssh2 时，在 -vvv 模式下出现以下错误
$ ssh2 -vvv -i .ssh2/id_rsa_2048_b -c aes128-ctr foobar@vm-333-333

在阅读“身份验证失败次数过多”后，我决定将以下几行添加到我的 sshd_config 文件中，然后重新启动它，但无济于事
MaxAuthTries 30
RSAAuthentication yes
PubKeyAuthentication yes
我将 .ssh2/id_rsa_2048_b.pub 文件导入授权密钥和 authroized_keys2，密钥上的所有权限似乎都设置正确。输入密码后，连接即可正常工作。我不确定如何继续。
