I've set up Vagrant to do development under Ubuntu on Windows machines twice recently. Both times I've had a spend some time remembering how to get the vagrant ssh command to work. It's a pretty simple thing but since it's caught me out twice I'll document what I did.
* Install Git. You've probably got this installed if you're using your machine for software development.
* Add the ssh executable to the path environmental variable. This is in C:\Program Files\Git\usr\bin\
The vagrant ssh command should now work.
