UDP File Sharer C is a simple file sharing system that can be used in tests or small applications.

Follow these steps to get UDP File Sharer C running without errors.

You need a C compiler installed. To do it, use the following command:

sudo apt-get install gcc

cd into the files directory and compile both. Use -o to choose executable name.

gcc sender.c -o sender
gcc receiver.c -o receiver

You should see both executable into directory.

Be certain that you have superuser permissions.

For sender choose the file to transfer, ip destiny and port destiny. Example:

./sender example.txt 255.255.255.255 90

For receiver choose the port to listen.

./receiver 90

You can (and should!) change #define parameters into source-code.

Change PACKETSIZE, BUFSIZE and DEFAULT_FILE_NAME to what you need.
