ssh 密钥错误 - 权限被拒绝（publickey、gssapi-keyex、gssapi-with-mic）

Amazon Ec2 :: Redhat 6. 64 位 我正在尝试遵循 socks5 指南（http://www.catonmat.net/blog/linux-socks5-proxy/) 在我们的其中一台服务器上打开一个袜子，但不幸的是，我在第 1 步就被困住了。

ssh -N -D 0.0.0.0:1080 本地主机

我收到错误

权限被拒绝（publickey、gssapi-keyex、gssapi-with-mic）。
我如何解决它 ？

答案1

检查服务器上的权限和所有权：

  • 家
  • .ssh 目录
  • 授权密钥

答案2

EC2 上的 SSH 不允许在没有 ssh 密钥的情况下进行连接（密码登录被拒绝，即使是本地主机）。例如 ssh -i mykey.pem -N -D 0.0.0.0:1080 localhost

答案3

ssh 查找名为的私钥文件id_rsa但找不到。您可能使用 ssh-keygen 生成密钥对，并为文件指定了其他名称。如果是这种情况，请尝试将这些文件重命名为 id_rsa 和 id_rsa.pub，或者尝试

ssh -v -i private_key_file_name -f -N -D 0.0.0.0:1080 localhost
