Usually with vagrant ssh <box> a connection to the box can be made via ssh. When putty is preferred as ssh client then this is possible, a vagrant plugin (vagrant-multi-putty) is available for this. just goto the command line and issue this command: vagrant plugin install vagrant-multi-putty Be sure that the putty binary can be
Based on this below one can setup a virtual development enviroment with vagrant, virtualbox and git. http://www.tjmaher.com/2016/05/setting-up-virtual-dev-environment-with.html This page describes how to do that on a computer with Windows 10. A. Download software: 1. https://git-scm.com/downloads/guis 2. https://www.vagrantup.com/downloads.html 3. https://www.virtualbox.org/wiki/Downloads B. Install software: 1. Install Virtualbox 2.
