Hello,

My name is Jun Takeshita.
You can call my name, Jun.

by the way, in our case, Vagrant can not connect to AWS as directory.
So we use multiple ssh portforwerding of openssh.
I tried to create ami using your this plugin.
But Vagrant was showing the above message.
Well, how can I use that using multiple ssh port forwarding of openssh?
If you have some idea, let me know.
