我遇到了 SSH 密码错误的问题（尽管密码是正确的）。我读过类似的帖子，但我觉得它们没什么用，因为我是新手。
以下是背景信息：我需要将一些文件从 Windows（SSH 服务器在这里运行；SSH 服务器由 SolarWinds SFTP/SCP 服务器运行）复制到专有硬件上的 Linux 系统。
我的 SCP 服务器文件夹设置在桌面 --> C:\Users\XYZ\Desktop\TFTP_Jani
起初，我尝试在 Linux 上进行简单的 scp
scp [email protected]:/dump/testfile.txt .
这要求添加到已知主机并要求输入密码..并且成功了
由于我正在自动执行复制过程，所以我想摆脱每次的密码验证，因此我在 Google 上搜索该主题后尝试添加/更改公钥对。
... 现在我甚至无法 ssh，它总是给我一个密码被拒绝的消息。
如果有人能抽出一些时间来帮助我，那就太好了
如果您有任何疑问，请告诉我
我做了什么
我尝试在 Windows 上设置新的 RSA 密钥和 DSA 密钥，还尝试在 Linux 中禁用 sshd_config 文件中的密码验证。我想我不确定是否还记得我尝试禁用密码验证的内容
以下是输出cat sshd_config：
:/etc/ssh# cat sshd_config

# This sshd was compiled with PATH=/usr/bin:/bin:/usr/sbin:/sbin:/opt/xyz/bin

# OpenSSH is to specify options with their default value where
# possible, but leave them commented. Uncommented options override the

如果您删除计算机上的 .ssh/known_hosts 和 Windows 机器的相关公钥条目，这将允许您仅使用密码通过 ssh 连接到它 - 因为密钥对将消失。
