Well, the problem is nothing to do with security given that you are
running as a full application and are connected via localhost.
The first thing I noticed was that you are not connecting to the same
port that the server is "servicing". You created the server socket on
port 4747. You need to connect to that port. I do not know what 8205 is
since you do not service that port in any of the code you have posted.
Also, just in case of a strange setup - check that you can "ping localhost"
meaning that your system knows that as a name. (Normally one should
have that setup but I have run into people who either deleted that definiton
from their hosts file or never put it in...)
