# aws-instance-monitor
# 
# This is a command-line tool, as well as a monitor/failover script that is designed
# for HA NAT, but should be usable when the following conditions are met:
# 
#     1. Used in AWS VPC Route Table - VPC routing describes methods of egress
#        for outbound traffic.  Typically, a NAT will have a 0.0.0.0/0 rule
#        and the route will be in a table associated with a Private Subnet.

# This script configures a linux box as a NAT router (PAT), suitable for use
# for AWS instances in a VPC Private Subnet to communicate with the Internet
#
# To setup a NAT:
#     # Create an AWS instance in Public Subnet
#     # Disable src./dest. check (networking menu in UI)
#
# To install, login to instance:
#     sudo su -
#     curl http://gist.github.com/.../raw/... | bash -s

#### Pulls Nodejs Source, Builds and Installs
#
#    I've run this successfully on an AWS EC2 instance running a RHEL AMI.  It
#    should work fine for installs on recent RHEL descended distros.
#
#    Installation is done by pulling this script from curl, and piping it
#    through bash, with appropriate parameters.  This must be run as root,
#    and local files (e.g. temp files) will be created relative to the
#    current working directory.

# Shell script for installation and setup of L2TP/IPsec VPN tunnel in site-to-site
# mode (e.g. connecting two inter-regional VPCs).  VPN software is libreswan.
#
# This should work on linux systems that are RHEL based.
#
# To install directly from this gist, you can curl the "raw" version and pipe that to
# "bash -s" while also defining the environment variables:

# Shell script for installation and setup of L2TP/IPsec VPN tunnel in remote access

#### Installs Nodejs and Express on a new AWS EC2 instance, running Linux AMI.
#    "Webserver" is about 10 lines of code in Express.js/Node
#    This works on RHEL systems (i.e. yum).
#    To install, do this on target machine (make sure to get the link from RAW gist):
#
#        $ sudo su -
#        $ curl https://gist...../raw/... | bash -s

#### Step 1:  Note OS
#    Installing Nodejs depends on which OS you're on.  Since I was on a AWS AMI
