Hi Marcio,

Which version of Ryu are you using?
The latest Ryu will listen on port 6633 and 6653 by default.

# Starts without any option
$ ryu-manager
loading app ryu.controller.ofp_handler
instantiating app ryu.controller.ofp_handler of OFPHandler
...

# Check socket state
$ sudo ss -pln | grep ryu-manager
tcp LISTEN 0 50 *:6653 *:* users:(("ryu-manager",pid=25094,fd=5)) tcp LISTEN 0 50 *:6633 *:* users:(("ryu-manager",pid=25094,fd=4))


To specify the port number Ryu should listen on, please use 
"--ofp-tcp-listen-port" or
"--ofp-ssl-listen-port" to ryu-manager.

$ ryu-manager --help
...(snip)...
  --ofp-ssl-listen-port OFP_SSL_LISTEN_PORT
                        openflow ssl listen port (default: 6653)
...(snip)...
  --ofp-tcp-listen-port OFP_TCP_LISTEN_PORT
                        openflow tcp listen port (default: 6653)
...(snip)...


Thanks,
Iwase

Dear,

Thanks for the last answer. I´m trying to connect a mininet network on a Ryu Controller(BGPSpeaker) on the same machine but after I start the Ryu, it appear not listening on 6633 port. Which port Ryu use? Simplifying, how could I connect Ryu and mininet on tha same machine?

Thanks for the help.
