There are a few logical/structural problems here:

Firstly, it is only one way because one end is sending and the other
listening but the sending end never listens and the listening end never
sends.

Secondly, control in this is going to be painful as it is.  You probably
want to thread your program so that each end can "talk" and "listen" at the
same time.  You could make it clunky and just switch between the two but
that would be rather un-intuative.

I would offer up some sample code but haven't done any socket programming in
Ruby and am currently at work  I bet someone will come along with more
useful info though (I offer this as something to get you going in the right
direction until then).
