Simplest analog of distributed file storages such as DropBox/SugarSync/etc.

• Python 2.7.5
• PostgreSQL
• Twisted
• Autobahn.ws
• OpenSSL
• SQLAlchemy ORM
• Flask
• pytest
• wxPython
• PyCrypto with python-cryptoplus extension

• opening/writing/renaming/removing/transfering file or catalog
• synchronization files
• encryption by AES-256/Serpent/Twofish
• console/GUI clients
• supporting multiple file servers
• shared files between users (via creating links)

Console application:
Client GUI:

For start working with distributed file storage you will need:

1. Run the server.py by doing

python server.py [port]

2. Start few (minimum one) file servers

# take example of fs.json
python fileserver.py [path_to_config.json] [port]

[path_to_config.json] its configuration file for fileserver.py, which contains:

• "path" its a place on HDD/SSD, where all files will be stored
• "base_dir" its just name for basic directory, which using for creating with "path" argument
• "server_ip" means IP-address of this computer, which get access to connecting new users
• "server_port" means port, which listening server for connected users
• "debug" - boolean flag, which means sending information about fileserver to server (by default its shall be false)

3. Open in your browser

   https://localhost:8080/

or run the Python console client

python client_console.py [port]

or run the Python GUI client

python client_gui.py [port]

NOTE: by default client applications using port=9000

TLS server keys and certificate can be generated by doing:

openssl genrsa -out server.key 2048
openssl req -new -key server.key -out server.csr
openssl x509 -req -days 3650 -in server.csr -signkey server.key -out server.crt
openssl x509 -in server.crt -out server.pem

To run the server 2 files are required.

Private key (with no passphrase set!):

server.key

Certificate:

server.crt
