如何设置Vagrant ssh代理转发？ [英] How to setup Vagrant ssh agent forwarding?

问题描述

我的目标是使用ssh密钥身份验证从VirtualBox VM连接到另一台计算机。我已经使用Vagrant（1.0.5）创建了VM。我还启用了config.ssh.forward_agent = true（如此帖子）。不幸的是，ssh转发似乎不起作用。

My goal is to connect from a VirtualBox VM to another machine using the ssh key authentication. I have created the VM with Vagrant (1.0.5). I have also enabled config.ssh.forward_agent = true (as suggested in this post). Sadly, the ssh forwarding does not seem to be working.

以下是这些步骤（在带有流浪汉和virtualbox的新鲜ubuntu上）：

These are the steps (on fresh ubuntu with vagrant and virtualbox):

1. 从主机登录到VM（使用--debug时，我看到转发已启用）

1. Log from the host machine to VM (when I use --debug, I see that the forwarding is enabled)

无用的ssh

vagrant ssh

从VM登录（ubuntu 12.04，注入了无用的ssh键）到外部计算机

Log from VM (ubuntu 12.04 with injected vagrant ssh key) to external machine

ssh -A sk@192.168.0.1

获取：权限被拒绝。

是否需要执行其他任何步骤才能使其正常工作？人们建议使用ssh-add -K。我不清楚在哪台计算机上。

Do I need to perform any additional step to make it work? People advice to use ssh-add -K. It is not clear for me on which machine.

推荐答案

我无法使ssh转发正常工作。我的解决方案是简单地在VM上生成新的ssh密钥：

I could not make the ssh forwarding working. My solution is to simply generate new ssh key on the VM:

1. 登录到VM： vasrant ssh


2. 在VM上生成新的ssh密钥： ssh-keygen


3. 将新的公共ssh上载到192.168.0.1：我手动完成。它可以自动化。


4. ssh -A sk@192.168.168.0.1 有效

1. Log to the VM: vagrant ssh
2. Generate a new ssh key on the VM: ssh-keygen
3. Upload the new public ssh to 192.168.0.1: I do it manually. It could be automatize.
4. ssh -A sk@192.168.168.0.1 works
