Hampton Roads

Introduction

ECO Districts Hampton Roads is a progressive project in Hampton Roads, Virginia. The building foundation for ECO Districts derives an emphasis on three imperatives--climate action, resilience, and equity. With over 5,000 homes and 12,000 residents in the community, in order to progressively transform a community of this size, communication is key. With the push of modern technology through websites and mobile applications today, the managing director of ECO Districts Hampton Roads, Gary Harris, decided that a web-based platform would promote community involvement which is where our team plays a role.

Instruction to SSH

Download the private key and locate it under your path ~/.ssh/

Open a terminal window and type:

ssh username@50.17.107.48 -p 22 -i ~/.ssh/keyname

Add a new user

After login-in via the terminal, type:

sudo adduser <new username>
sudo touch /etc/sudoers.d/<new username>
sudo nano /etc/sudoers.d/<new username>

And on the nano widow, type:

<new username> ALL=(ALL:ALL) ALL

type CTRL+X, 'y' and ENTER to save and exit

making new ssh key by using ssh-keygen

On the client computer, open terminal and type:

ssh-keygen

By following the step, you can generate private and public key in the path ~/.ssh

Now you should copy the value of key into the server.

On your server side terminal, type

sudo nano .ssh/authorized_keys

Copy the public key value into this and save

Give permission by typing

chmod 700 .ssh
chmod 644 .ssh/authorized_keys

Change the SSH port from 22 to 2200

sudo ufw allow 2200
sudo ufw allow 80
sudo ufw allow 123
sudo ufw enable
