socketConcurrentTCP

This repository houses the source code of a music server system designed to accommodate multiple users concurrently. At its core, the project entails the implementation of a concurrent server using TCP sockets to facilitate client-server communication.

At the current development point, the server is capable of handling the following actions:

• Inclusion of music data
• Removal of music data
• Preview listing by year filter
• Preview listing by year and laguage filter
• Preview listing by genre
• Listing by ID
• Listing of all available songs

Compilation and Execution

Dependencies

To compile the server SQLite3 will be needed, to install it simply run:

  sudo apt-get install libsqlite3-dev

Compiling the Server

To compile the server, you can use the gcc compiler as follows:

  gcc -o <executable_name>.exe <source_file>.c <dependencies>

Replace <executable_name> with the desired name of the executable, <source_file> with the name of the source file and with its necessaries dependencies.

Example:

  gcc -o server.exe server.c -lsqlite3

This will generate an executable file called server.

PS. Further modifications can be made in its system for it to run as a standalone program in local mode too. For it, just go to system.c file, set the DEBUG flag to 1 to activate its local output, comment the code sections marked as "Comment for standalone" and write a main function to call serve_client_admin with a mock ip and port. Then compile it with gcc -o local_system.exe system.c -lsqlite3.

Running the Server

To run the server, simply type the following command:

  ./<executable_name>.exe

Replace <executable_name> with the name of the executable

Example:

  ./server.exe

The server will now be listening for connections on the specified port. The default port is set to 3490.

Compiling the Clients

To compile the clients, you can use the gcc compiler as follows:

For normal users (read only):

  gcc -o <executable_name>.exe client.c

For admin (read and write):

  gcc -o <executable_name>.exe admin.c

Replace <executable_name> with the desired name of the executable.

Example:

  gcc -o client.exe client.c

  gcc -o admin.exe admin.c

This will generate an executable file called client.exe for normal users (read only) and admin.exe for admin users (read and write permissions).

Running the Clients

To run the clients, simply type the following command:

  ./<executable_name>.exe -i <server_machines_ip>

Replace <executable_name> with the name of the executable and <server_machines_ip> with the IP where the server will be running. In the case where -i <server_machines_ip> is not specified localhost will be used as IP.

Example:

  ./client.exe -i 127.0.0.1

  ./admin.exe -i 127.0.0.1

After successful connection, you can interact with the server as intended.
