Hello
I configured a linux powered machine to run as OpenFlow switch (OVS) and
connect it with out-of-band NOX controller (NOX controller was initialized
by following instruction "*nox_core -i ptcp:6633 routing*"). When I
connected the switch with controller i got following error message
*openflow
Which version of NOX is this? Has it been modified at all?

./nox_core -V gives output

Hi,
I tried to set up the example network as in OpenFlowVMS description page. I
also installed and could run successfully NOX controller as well as I could
run the vms-start.py.
the screen for Of1, Of2, Host 1, Host 2 are successful. But, the ping
failed. Host unreachable from host1 to host2 or vi
I don't think I'm aware of any bugs that would cause this in stock NOX, but
can you retry with the destiny branch? If it continues to happen with the
destiny branch, can you please use tcpdump or wireshark to send a trace of the
connection between NOX at the switch?

What is the commandline you're using to run NOX?

Hi,
As per the manual:
$ nox_core -i ptcp:6633 routing
Thanks,

If your topology has no loops, try "nox_core -v -v -i ptcp:6633 pyswitch".
Also, if you're not using the destiny branch, you might try that...

send_openflow_packet()'s API is kind of broken due to changes made since
earlier versions of OpenFlow, and is very, very likely to be removed
altogether in the next major release of NOX. There are other ways to do the
same thing. If you look at the source of send_openflow_packet(), you'll see
I tried but still facing the same error. Host Unreachable on Host 1 screen.
Also, I notice the following error message in all the screens (Of1, Of2,
Host 1, Host 2)

Hi guys,
I have successfully installed a Virtual Machine containing NOX and Mininet.
Following the walkthrough I was able to transform an HUB to a learning
switch.
Moreover I premit that I've well understood how components are linked by
mean of "meta.xml" files,
Now I'm trying to use the "sampl
I forgot to mention that I think OpenFlow VMS is no longer really supported,
with the idea being that mininet supercedes it. Maybe KK will chime in here.
:)
It seems like maybe you have a problem with the switches/VMs and not really a
NOX issue. You could try putting a print statement in pysw
Did you run the boot.sh script specifying only core apps?
Perhaps even more importantly, it seems like you're using a very old version
of NOX. Unless your switches don't support OpenFlow 1.0 or you have some
other reason not to do so, I would suggest you start by upgrading to NOX
destiny.

OK. Thank you. I will try that too. In the meanwhile, I am also going to try
out Mininet.
Thanks again,
Daniel

I agree that it's probably not a NOX problem. I'm not sure mininet will help
directly either, though our VM should mostly work out of the box.
I would suggest making absolutely sure that your switches are starting and
loading correctly.

Hi All
May not be the right forum but I would sincerely appreciate a pointer. How
does the openvswitch communicate with a controller? What marshaling
technique is used given that the controller can be implemented in any
language? Where can I read about this?
Thanks in advance
