Android SOCKS proxy Tunneling

The problem statement for this Android SOCKS proxy tunneling project is as follows: Given 3 devices: 1) Alice, 2) Bob and 3) Eve.

Alice has IP address 1.1.1.1 and is a home computer with Windows 7/8/8.1/10 behind a router with no dedicated open ports and the router settings cannot be changed.

Bob has IP address 2.2.2.2 and is a non-rooted Android device behind a router with no dedicated open ports and the router settings cannot be changed.

Eve has IP address 3.3.3.3 and is either a Windows or Linux VPS server with dedicated open ports.

Because Alice and Bob have no dedicated open ports for their IP addresses 1.1.1.1 and 2.2.2.2 (some) traffic has to be routed through Eve’s IP address 3.3.3.3 in order for Alice and Bob to communicate with each other.

The goal would to make Alice act as a client and Bob as a SOCKS proxy server after they are connected with each other through Eve. This means that the solution should be compatible with the SOCKS (Socket Secure) protocol:

[login to view URL]

[login to view URL]

To achieve this goal, do the following:

1. Write the programs [login to view URL], [login to view URL] and [login to view URL]

2. Show that after running program [login to view URL] on the computer “Alice”, running the program [login to view URL] on Android device “Bob” and running the program [login to view URL] on the computer “Eve”, Alice can go to [login to view URL] and see that her IP address is now Bob’s IP address (2.2.2.2) instead of 1.1.1.1

[login to view URL] HTTPS webpages must be visited by Alice and the server logs for this custom page will be checked to see if Bob’s IP address shows up instead of Alice’s IP address.

Note that the IP addresses 1.1.1.1, 2.2.2.2 and 3.3.3.3 are not the actual IP addresses and were mentioned for illustration purposes. Only the IP address of Eve can be assumed to be static.

The IP addresses for Alice and Bob can change. The goal would to make Alice act as a client and Bob as a SOCKS proxy server after they are connected with each other through Eve.
