![无密码 ssh2 无法工作,多次身份验证失败](https://linux22.com/image/1504690/%E6%97%A0%E5%AF%86%E7%A0%81%20ssh2%20%E6%97%A0%E6%B3%95%E5%B7%A5%E4%BD%9C%EF%BC%8C%E5%A4%9A%E6%AC%A1%E8%BA%AB%E4%BB%BD%E9%AA%8C%E8%AF%81%E5%A4%B1%E8%B4%A5.png)
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。
