Reverse Port Tunneling with EC2

Reverse port tunneling is used to give a user outside of a networks firewall accesst to a computer inside the firewall where direct SSH connections aren't allowed. It works by the in-firewall computer SSH'ing to a middleman computer that then forwards incomming SSH connections on a given port to the firewalled computer.

Setup the middleman

Get an ubuntu EC2 instance
Download it's security keys (both in-firewall and out-firewall computers will need the private key)
Setup the security group to allow connections on port 10002
SSH into the middleman and add: GatewayPorts yes to /etc/ssh/sshd_config

##VGG16 model for Keras

This is the Keras model of the 16-layer network used by the VGG team in the ILSVRC-2014 competition.

It has been obtained by directly converting the Caffe model provived by the authors.

Details about the network architecture can be found in the following arXiv paper:

	Viterbi algorithm for finding the most likely state sequence of a simple
	hidden markov model.

	# https://en.wikipedia.org/wiki/Viterbi_algorithm

	The Model
	---------
	The HMMs considered in this code are extremely simple. Every hidden state
	is uniquely associated with an output symbol, but the link is "fuzzy". That is,

	// I don't dance now, I make muscle moves...
	// Configurable Params
	MaxMoveF = 4000
	MaxHoldF = 1.334 * MaxMoveF
	MaxTorque = 500
	MaxHoldTorque = 1.334 * MaxTorque
	MaxMoveSpeed = 4.5 // m/s
	HillParamA = 0.25 // Coefficient of shortening heat in Hill's muscle model

	SetAngularDrag(0)
