Peer-to-Peer File Sharing System:

The Peer-to-Peer File Sharing system is written using Python programming language.

Requirements:

* Python version: 2.* , should be equal or greater than 2.6.

Below are the steps to be followed to execute and run the program.

Method 1:

Central Indexing Server:

1.1	File name “CIndexServer.py” contains the source code
	
1.2	To execute the program, follow the below steps.

		$ python CIndexServer.py [-h] -p PORT [-r REPLICA]

	Standard Arguments for talking to Central Index Server

	optional arguments:
		  -h, --help            show this help message and exit
		  -p PORT, --port PORT  Server Port Number
		  -r REPLICA, --replica REPLICA
                    			Data Replication Factor

	Note: * arugment -p is mandatory
	      * default replication factor is set to 1

	Example:
		$ python CIndexServer.py -p 3344 -r 2
		or
		$ python CIndexServer.py -p 3344
	
	The above example will start the central index server on socket port 3344 with replication factor 2 or 1.

Peer:

2.1	Depending on the requirement, open n number of terminals (here n = 3).

2.2	Change directory to Peer#(1/2/3)

2.3	File name “Peer.py” contains the source code
	
2.4	To execute the program, follow the below steps.

		$ python Peer.py [-h] -s SERVER

	Standard Arguments for talking to Central Index Server

	optional arguments:
		  -h, --help            show this help message and exit
		  -s SERVER, --server SERVER
		                        Index Server Port Number

	Note: * arugment -s is mandatory and need to specify Index Server Port Number.

	Example:
		$ python Peer.py -s 3344

2.5	This outputs the below:  

		eg: $ python Peer.py -s 3344
		Starting Peer...
		Registring Peer with Server...
		registration successfull, Peer ID: 127.0.0.1:23838
		Stating Peer Server Deamon Thread...
		Starting File Handler Deamon Thread...
		********************
		1. List all files in Index Server
		2. Search for File
		3. Get File from Peer
		4. Exit
		*****
		Enter choise : 

Method 2:

The entire process is automated using shell script.

Requirements to run the shell script:

	1. gnome-terminal

To execute the program, follow the below steps.

	$ chmod +x start.sh
	$ ./start.sh
