我在我的Mac上设置了一个Ubuntu VM，我想将文件复制到其中，但是我不断收到permission denied和Permission denied (publickey,password)错误。我打开了vm，我知道安装了ssh-server，我可以从主机ping地址。我尝试将我的公钥从~/.ssh/id_rsa.pub复制到vm上的home/osboxes/.ssh/authorized_keys，但这似乎也没有什么区别。
有没有人对可能出错的地方有什么建议？我用-vvv标志运行它，它说密码授权的数据包响应是receive packet: type 51。
ssh -vvv osboxes@192.168.1.11

我遇到了类似的问题，并且意识到使用ssh的root登录已被禁用。
确保在SSHD配置中，您具有PermitRootLogin
希望有帮助
答案 1 :(得分：0)
此身份验证失败的可能并发症之一是在服务器上禁用了authorized_keys文件。有时，名称会更改，或者被带注释的行禁用。配置位于
/ etc / ssh / sshd_config
，示例行是：
#AuthorizedKeysFile %h/.ssh/authorized_keys
答案 2 :(得分：-1)
SSH甚至不知道你的密钥，所以它甚至都没有尝试使用它。将密钥添加到配置文件中，SSH客户端知道它存在：
首先让我们备份您的配置文件：
cp ~/.ssh/config ~/.ssh/config-001
然后我们添加密钥名称：
echo -e "\nIdentityFile ~/.ssh/id_rsa" >> ~/.ssh/config
