ssh 无密码登录到 localhost

Question

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 key 并将公钥附加到 authorized_keys 的正常步骤。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。

Answer 1

由于您似乎有多个键，我会将特定键分配给 ~/.ssh/config 中的特定连接.

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 .
