ssh in windows

gistfile1.txt

The **S**ecure **Sh**ell ("SSH") protocol is all about security and Vagrant is prepackaged with an SSH key. Unfortunately, PuTTY is not compatible with OpenSSH, out-of-the-box. Consequently, PuTTY will **not** recognize the `insecure_private_key` (which is in OpenSSH format) provided by Vagrant as a valid, private key.
>The file is named `insecure_private_key` only because it is not very *private*, in that it is publicly available, because it ships with Vagrant. You can regain the security offered by the SSH protocol by creating your own SSH key pair and editing the [Vagrantfile](http://docs.vagrantup.com/v2/vagrantfile/ssh_settings.html), accordingly.

A workaround is to use [PuTTYgen](http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html) (a free, open-source RSA and DSA key generation utility) to import and convert the `insecure_private_key` into PuTTY's format (a `.ppk` file). To do so, simply:
1. Open the PuTTYgen utility;
1. Click on the `Load` button;
1. Navigate to the `...\.vagrant.d\` folder in your local machine's Home Directory; e.g.
  * Windows XP: `C:\Documents and Settings\{your username}\.vagrant.d\`
  * Windows 7:  `C:\Users\{your username}\.vagrant.d\`
1. Double-click on the `insecure_private_key` file;
1. Toward the bottom of the PuTTYgen dialog box, change the value in the `Number of bits in a generated key:` field to `2048`;
1. Click on the `Save private key` button.

Run "vagrant ssh-config" and make note of the HostName, User and Port being used.

Then, launch PuTTY and enter the following connection information:

Category | Sub-category | Field | Value
--- | --- | --- | ---
Session | | **Host Name:** | 127.0.0.1
| | | **Port:** | 2222
| | | **Connection type:** | SSH
| Connection | Data | **Auto-login username:** | vagrant
| Connection/SSH | Auth | **Private key file for authentication:** | Click on the `Browse` button and find the `.ppk` private key you just converted
| Session | | **Saved Sessions** | vagrant (and then click the `Save` button for the `Load, save or delete a stored session` area)

Finally, click on the `Open` button, at the bottom of the PuTTY window, to log in to your Vagrant VM.
