UDP File Synchronizer

File synchronizer project for the Operating Systems II class at INF-UFRGS

Developed by:

• Eduardo Fischer
• Matheus Woeffel
• Rodrigo Bastos

Dependencies

Before compiling, make sure you have all the dependencies installed

• readline.h

On Debian based platforms, like Ubuntu:

sudo apt-get install libreadline-dev 

If you use a platform with yum, like SUSE:

yum install readline-devel

Build

Once you have installed all the dependencies, get the code:

git clone https://github.com/eduardofischer/udp_filesync.git
cd udp_filesync

To build the client and server binaries, run:

make

Usage

Start the UDP FileSync server by running:

./server [-p PORT] [-b MAIN_SERVER_IP]

Then you can connect a client using:

./client <username> <server_ip_address> [<port>]

• When a client first connects to the server a directory named sync_dir is created in the client host.
• sync_dir will then be automatically synchronized among all the client instances connected to the server.

Client CLI

Once the client is connected to the server, a command line interface becomes available with the following options:

upload <filepath> - Uploads a file to the users shared directory

download <filename> - Downloads a file from the users shared directory

delete <filepath> - Deletes a file to the users local sync_dir directory

list_server - Lists all the files in the users shared directory

list_client - Lists all the files in the users local sync_dir directory

exit - Disconnects the client from the server
