我正在尝试为分布式计算教程设置无密码登录到我的本地主机。（我已经为多个远程主机成功设置了它。）我完成了生成 rsa 密钥并将公钥附加到的正常步骤，authorized_keys但仍然提示我输入密码。我还启用了RSAAuthentication和PubKeyAuthentication在/etc/ssh_config. 按照我看到的其他建议，我尝试了：

chmod go-w ~/
chmod 700 ~/.ssh
chmod 600 ~/.ssh/authorized_keys

但问题仍然存在。

这是 ssh -v localhost 的输出：

有什么建议么？我正在运行 OSX 10.8。

由于您似乎有多个键，我会将特定键分配给~/.ssh/config.

例子：

Host local
    HostName 127.0.0.1
    Port 22
    User your_username
    IdentityFile ~/.ssh/your_key-id_rsa

然后尝试ssh local。

我有同样的问题。我检查了系统密码和组文件，发现我的用户和组不存在。要构建这些文件（我的用户是域用户），我需要在 cygwin shell 上运行两个命令：

mkpasswd -l -d > /etc/passwd

mkgroup -l -d > /etc/group

之后，ssh 工作正常！

看起来您在连接到 时使用的是协议版本 2.0 localhost，因此请尝试authorized_keys移至authorized_keys2.

资料来源：这篇文章解释了两个密钥文件之间的区别。

我束手无策......我错误地认为ssh-copy-id它是一个仅限 Linux 的实用程序。最后我忍住了我的骄傲，输入了命令是 macOS 终端，它成功了！

ssh-copy-id me@sshd-server

我不知道魔法是做什么ssh-copy-id的，但它确实有效。我可以使用简单的命令在没有密码的情况下成功登录：

ssh me@sshd-server

我的运气为零cat id_rsa.pub >> ~/.ssh/authorized_hosts。每次我尝试通过 ssh 连接到服务器时，它都会不断询问我的密码。这是正确的 600 权限authorized_hosts和 700权限~/.ssh。
