Password Authentication only denied OpenSS?

Question

专指使用PasswordAuthentication建立联系。我知道有很多关于公钥许可被拒绝的帖子。远程SSH连接尝试:

• sshd PC UserName@staticIP: Permission denied (publickey，)keyboard-interactive)
• root@staticIP: Permission denied (publickey，)keyboard-interactive)

我在一个(公共)路由器后面有一个分配给它的static IP的windows PC。现在，我只想在进行密钥身份验证之前获得一个初始ssh连接。我没有得到密码提示:

设置中:

• PermitRootLogin是的
• PubkeyAuthentication没有
• PasswordAuthentication是的
• 日志是的
• LogLevel详细

在公网路由器上设置static IP:

• 在我的路由器上允许SSH和端口22，入站和出站。
• 当我尝试ssh时，我在路由器的防火墙日志中没有日志信息。
• 我有端口转发，端口22到PC，我有sshd运行。

sshd PC:防火墙有入站规则允许端口22 SSH。允许应用程序通过Windows Defender防火墙进行通信;在OpenSSH Server和OpenSSH Server的Private和Public上也允许。

HrPing is successful: HrPingstaticIP-p 22 -n 4 -l 1000

使用PowerShell作为管理员以及在Ubuntu PC上我尝试过:

• sshsshd PC UserName@staticIP-p 22
• ssh root@staticIP-p 22

在sshd/Server PC>服务比;OpenSSH SSH Server>登录:应该选择本地系统帐户还是此帐户-然后选择用户?

In ProgramData>SSH祝辞日志:

10952 2022-06-15 16:36:18.724 Connection from 102.250.4.93 port 12692 on <Local LAN IP address sshd PC> port 22
10952 2022-06-15 16:36:18.987 Connection reset by authenticating user <UserName> 102.250.4.93 port 12692 [preauth]

我在OpenSSH下的windows eventViewer中没有收到任何消息。客户端和sshd PC上都没有密钥。在初始连接尝试中，sshd PC的指纹被复制到客户端的known_hosts文件夹，但这也以拒绝权限结束。

Answer 1

您可以从调试输出

中看到

debug1: Authentications that can continue: publickey,keyboard-interactive

和最后的错误消息

Permission denied (publickey, keyboard-interactive)

服务器是而不是接受密码验证方法(否则单词password将包含在列表中)。

如果您自己将PasswordAuthentication设置为yes，请确保重新启动ssh服务以使更改生效。
