# This is a short collection of tools that are useful for managing your
# known_hosts file. In this case, I'm using the '-f' flag to specify the
# global known_hosts file because I'll be adding many deploy users on this
# system. Simply omit the -f flag to operate on ~/.ssh/known_hosts

# Add entry for host
ssh-keyscan -H github.com > /etc/ssh/ssh_known_hosts

# Scan known hosts
ssh-keygen -f /etc/ssh/ssh_known_hosts -H -F github.com

##Setting up Vagrant for Node.js development

These are instructions for an internal project setup for node.js development in the same enviromment regardless of host OS. Some items may be specific to our project and internal processes, but I put it here as a starting point for others or help to setting up your own OS.

There is an internal postinstall.sh on install of the vagrant box mentioned here, but I prefer to roll my own and outline the essential steps so that other can input the items that they require.

###Setting up Vagrant box

• Install VirtualBox
• Download and install Vagrant
• Follow the instructions for creating an ubuntu 'precise32' vagrant box on the 'Getting Started' page (really quick)
