ryu-client is kinda debug tool. Unlikely you need it. I guess that we
should rename or move it to avoid confusion.
There is nothing to configure for Ryu if you just want a switch to
connect with Ryu. All you need to do is configuring the switch.
I can make OVS connect with Ryu in the following way.
On the OVS node:
fujita@ovs-node:~$ sudo ovs-vsctl add-br dp0
fujita@ovs-node:~$ sudo ovs-vsctl set-controller dp0 tcp:192.168.13.1:6633
On the Ryu node, I just run ryu-manager with 'verbose' option:
ryu-node:~ fujita$ ryu-manager --verbose
loading app ryu.controller.ofp_handler
instantiating app ryu.controller.ofp_handler
connected socket:<socket fileno=8 sock=192.168.13.1:6633

Note that I use 'verbose' option since by default Ryu doesn't show
anything when it accepts a new connection.
Ryu just accepts a new connection but does nothing after that. If you
want to try something, then run simple_switch.py (works as L2 switch):
ryu-node:~ fujita$ ryu-manager ~/git/ryu/ryu/app/simple_switch.py
loading app ryu.controller.ofp_handler
loading app /Users/fujita/git/ryu/ryu/app/simple_switch.py
instantiating app /Users/fujita/git/ryu/ryu/app/simple_switch.py
instantiating app ryu.controller.ofp_handler
Thanks,
