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? -- Murphy On Friday, May 2

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... -- Murphy On Friday, May 27, 2011 11:06:55 AM Daniel Philip wrote: > Hi, > > As per the manual: > > $ nox_core -i ptcp:6633 routing > > Thanks, > Dani

Re: [nox-dev] send_openflow_packet interface with buffer and ofp_action_header

2011-05-27 Thread Murphy McCauley
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 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

Re: [nox-dev] Unable to run components under 'netapps'

2011-05-27 Thread Murphy McCauley
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. --

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. On May 27, 2011, at 12:23 PM, Murphy McCauley wrote: > I
