title: vagrant rsync : Enter passphrase for key
body: <p>when I run vagrant rsync, the prompt keep me asking 'Enter passphrase for key' and then the vagrant password for the user.
  All of my collegue that are working with the same vagrant configuration dont' insert any password after the vagrant rsyn command.</p>
  
  <p>It looks like it can't create the /home/Administrator/.ssh folder, but I run the command as normal user.</p>
  
  <p>The output of vagrant ssh-config is</p>
  
  <pre><code>Host default
    HostName 127.0.0.1
    User vagrant
    Port 2222
    UserKnownHostsFile /dev/null
    StrictHostKeyChecking no
    PasswordAuthentication no
    IdentityFile 
  C:/Users/USERNAME/projects/fisch/VagrantVM/.vagrant/machines/default/virtualbox/private_key
    IdentitiesOnly yes
    LogLevel FATAL
  </code></pre>

  <p>After some hours spent investingating about it seems that the problem is related to cygwin:</p>
  
  <pre>
  
      C:\Users\USERNAME\projects\fisch\VagrantVM>ssh -p2222 vagrant@localhost
       Could not create directory '/home/Administrator/.ssh'.
       The authenticity of host 'localhost (127.0.0.1)' can't be established.
       RSA key fingerprint is dd:8f:cf:c0:7a:b9:6b:b5:2e:78:70:4b:8f:e3:bf:47.
       Are you sure you want to continue connecting (yes/no)? yes
       Failed to add the host to the list of known hosts     (/home/Administrator/.ssh/known_hosts).
  
  </pre>
  
  <p>And again the error related to the wrong path, I'm expecting <strong>/home/USERNAME/.ssh</strong></p>
