Hmm. Might I recommend some other means of sharing your code? The
unrar-free utility from the Debian repo won't extract more than the
first file (accounts.txt), and I don't know if that's a problem with
unrar-free or your file. A better-known format like zip or tar.gz
would make things easier.

What's the broadcastIP address you're using? (As mentioned above, I
can't see your source code.) Is it the appropriate address for one of
your interfaces?

Broadcast UDP is a bit tricky sometimes. You need to explicitly enable
broadcasting on the socket -  I've not done this in Python but two
seconds with Google suggests that this is needed:

udpSock.setsockopt(socket.SOL_SOCKET, socket.SO_BROADCAST, 1)

You may have already done this, but I don't know without seeing your code.

My crystal ball tells me that you're trying to bind to a broadcast
address (eg 192.168.0.255). This is incorrect; you need to instead
bind to your own IP address (eg 192.168.0.17). You can probably just
do this:

udpSock.bind(('', broadcastPort))

However, my crystal ball has been playing up a bit lately, so it's
hard to be sure.
