尝试在 Mac 上使用 PuttyGen

Question

我目前有一个学校项目，我必须使用 vagrant 和 virtual box 启动 VM。它要求我使用Putty，这在使用terminal 本身的mac 中几乎是可以避免的。但是，我达到了应该使用Puttygen 的地步。确切的说明是：

13. Download PuTTYgen and open it.
14. Click on File -> Load Private Key
The file we are looking for is in the ~\trusty64\.vagrant\machines\default\virtualbox folder (which was automatically created when you installed and configured Vagrant).
Change the visibility to “All Files” and select private_key
Click OK, on the following success message.
15. Click “Save Private Key”, then click Yes in the pop-up window.
16. Save it in any directory for example ~/lucid32. Give it the following name: putty_key

现在的问题是OSX 上没有PuttyGen。 This 问题解决了这个问题。

首先我通过调用ssh -i private_key vagrant@127.0.0.1 -p 2222ssh'ed 使用位于文件本身中的私钥：

我不确定这是否有效。如何保存私钥？所以我继续尝试puttygen privatekey -O private-openssh -o privatekey.pem，我得到了：

puttygen: unable to load file `privatekey': unable to open file 

我应该在这里做什么？

尝试在终端输入puttygen .vagrant/machines/default/virtualbox/private_key -o putty_key保存私钥。
