我已按照一些教程设置 RSA 公钥认证，但似乎无法使其正常工作。我可以不使用密码通过 SSH 进入远程计算机，但当我尝试 scp 文件时，即使它接受密钥，系统仍会提示我输入密码...
这是输出...

提前感谢你的帮助！
答案1
你的密钥未被接受：
debug1: Next authentication method: publickey
debug1: Offering RSA public key: /home/nsizemore/.ssh/id_rsa
debug1: Authentications that can continue: publickey,password
debug1: Next authentication method: password
请检查服务器日志而不是客户端日志。
答案2
您可能正在使用公钥（而不是私钥）进行连接。确保 id_rsa 确实包含您的私钥。
