Avoid the automatic modification of sys.path because it hurts
ryu-as-a-library use cases.
An example is the recent versions of neutron OVS-agent,
which optionally imports OVS python bindings, and ends up to
use a wrong copy in ryu.contrib.ovs.

I used the attached simple_switch_stp_13.py,

Hi Fujita-San, Kobayashi-San,
This page might be helpful.

According to this page, python-eventlet version is still 0.13 in Ubuntu 14.04
now.
Ubuntu 15.04 will update python-eventlet to version 0.16, though...
Thanks,

Unfortunately, No... I tried to check Ubuntu 14.04 now.
vagrant@ubuntu1404:~$ cat /etc/lsb-release
DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=14.04
DISTRIB_CODENAME=trusty
DISTRIB_DESCRIPTION="Ubuntu 14.04.1 LTS"
vagrant@ubuntu1404:~$ apt-cache show python-eventlet | grep -i ^version
Version: 0.13.0-1ubunt
Thanks! I've applied #2-8. 0.15 or the newer is already shipped with
major distributions like Ubuntu? If not, I tend to postpone this.

Hi Iwase,
Sorry I did not make this thing clear before. I do not want ryu to discover the
switch-host link and I am taking care of this kind of links somewhere else in
my code. But topology.api cannot always discover all the switches and
switch-to-switch link sometimes. I tried several times. S
Hello,
I am working with Ryu controller in integration with ofsoftswitch13 as the
soft switch. I want to write a new OpenFlow Message which needs to be
implemented both at the switch side and the controller side. I am aware of
implementing it at the switch side, but I am not sure what all changes
Hi
Can you dump flow entries which in the LINC switch?

Hi
I think there should be 3 computer in this experiment.
One controller and two host
and simple switch should run on the controller

Hi Gavin
Please keep the mailing list.
What topology you use in this experiment?
Also, you can add --verbose option to see debug information from ryu, if
there is any problem.

Hi Iwase,
Thanks for your reply,but... I still have no idea. If I want to try a
Experiment to implement one PC ping another (the source host) will get
''host unreachable command. How can I do?
P.S. Because I do not know how to reply you directly, I post the new
article!
Thanks a lot,

Hi
I follow this web page(
http://www.tcpipguide.com/free/t_DNSMessageHeaderandQuestionSectionFormat.htm)
to implement the parser.
I'll write a test program as soon as possible.

Hi Iwase,
I ran tcpdump on the switches but they don’t see any bpdu packets ,infact they
they don’t see any packets at all.
I also switched to simple_switch_stp_13 as it seemed a better option.
And when I checked the ryu log ,it shows that ryu is just blocking a port on
the switches then disabli
