title: Git clone via SSH in Cygwin does not prompt for password, errors out instead
body: <p>I am trying to use the following command to do a Git clone via SSH from a password-protected headless server. I am using Cygwin with OpenSSH. I can do an interactive SSH to the server without issues using Cygwin. The issue only occurs in Cygwin and not in the Windows Command Prompt.</p>
  
  <pre><code>git clone ssh://username@server.edu:path/to/repo/reponame
  </code></pre>
  
  <p>I do not get any sort of password prompt. I get the following error:</p>
  
  <pre><code>Cloning into 'reponame'...
  ssh_askpass: exec(/usr/lib/ssh/ssh-askpass): No such file or directory
  Permission denied, please try again.
  ssh_askpass: exec(/usr/lib/ssh/ssh-askpass): No such file or directory
  Permission denied, please try again.
  ssh_askpass: exec(/usr/lib/ssh/ssh-askpass): No such file or directory
  username@server.edu: Permission denied (publickey,password).
  fatal: Could not read from remote repository.
  
  Please make sure you have the correct access rights
  and the repository exists.
  </code></pre>
  
  <p>I am assuming this is caused by SSH and the Cygwin settings.</p>
  
  <p>Unsuccessful "solutions" I have tried so far are:</p>
  
  <ol>
  <li><p>Using a command of the form</p>
  
  <p>git clone ssh://username:password@server.edu:path/to/repo/reponame</p></li>
  <li><p>Entering</p>
  
  <p>unset GIT_ASKPASS
  unset SSH_ASKPASS</p></li>
  </ol>
  
  <p>and retrying the clone.</p>
  
  <ol start="3">
  <li>Opening an x-forwarding server on my local machine and retrying the clone.</li>
  </ol>
  
  <p>The solution that finally worked was opening up a Windows Command Prompt and using that instead of a Cygwin terminal. What setting in Cygwin could have caused the problem, and how do I fix it?</p>
