ssh 转发到主/从节点

ssh 转发到主/从节点

使用 putty 和 pageant,我想登录到主节点,然后从那里 ssh 到代理。转发在 putty 选项中启用。我可以 ssh 到主节点而无需密码提示。但是,从主节点到从节点,它要求输入密码。虽然从节点的 authorized_keys 中没有公钥,但我希望转发也能做同样的事情。不是吗?

这里遗漏了什么配置吗?

答案1

代理转发使“中间” ssh 服务器能够将您使用的密钥转发到您正在联系的下一个服务器。它不会神奇地让下一个服务器决定允许该密钥访问。与任何其他密钥一样,您需要设置“从属”服务器以实际允许它,方法是将其包含在您正在连接的帐户的 authorized_key 文件中。
