Hi,
I'm trying to run the app/cli.py application. I've found 2 versions of the
file: an older one supporting telnet and a newer one supporting ssh.
I've also created the required logger.py, management.py, plogger.py and
call_via_pipe.py files.
They both run, but when trying to connect the server it fails. It seems the
server is not running at all (netstat -lutpn doesn't show any listening
4989, nor 4990, ports)
Would anyone shed some light on this issue?
Note: I've got the latest Ryu code (from github/osrg) and the OS in Linux
Ubuntu12.04 32bit with python2.7.5
I tried to replace gevent.spawn() and gevent.server.StreamServer with
hub.spwan() and hub.StreamServer (from ryu.lib.hub).
Now, I see the server is running, but any telnet client attempting to
connect, result with the following hub/greenlet exception:
CLI ('127.0.0.1', 41423) Setting termtype to ansi
hub: uncaught exception: Traceback (most recent call last):

get_hub
raise NotImplementedError('gevent is only usable from a single thread')
NotImplementedError: gevent is only usable from a single thread
So, I guess I'm not using hub in the correct way. Can anyone point me to the
correct path of using hub module?
Thank you and regards,
David Ganor
