Shellhub

Abstract

1. Introduction

ShellHub is a centralized SSH gateway that allows users to remotely access and manage their servers and devices from anywhere, using a web browser or mobile app. It offers a secure and convenient way to connect and control your servers and devices.

One of the main benefits of ShellHub is that it acts as a central gateway for all your Linux servers and devices, allowing you to access them from anywhere with an internet connection. This means you don't have to worry about getting its public IP address, configuring the router, changing VPN/firewall settings or using a jump host to access your servers and devices. This can be inconvenient and time-consuming.

ShellHub also allows you to access and manage multiple servers and devices from a single interface, saving time and making it easier to keep track of all your servers and devices. The platform also includes enhanced security features such as public key authentication, SSH firewall rules to prevent unauthorized access, audit logging, and session recording to provide a record of activity for compliance purposes.

2. Objective

:computer: Get seamless remote access to any Linux device. Centralized SSH for the edge and cloud computing

This project demonstrates how Go, Raspberry Pi can be applied to a real-world Blockchain & Cloud Computing problem.

8. Viva / Review Questions

Common questions examiners ask for projects in this domain.

1. Why does this problem need a blockchain or cloud-native design?
2. Explain the smart contract / infrastructure components and how they interact.
3. How are gas costs or cloud costs kept under control?
4. How is the system secured (keys, IAM, access control)?
5. How would the solution scale to many more users?
