Re: [nox-dev] monitoring usage error
Hi, the resolve() function expects a string. You don't even need to import the monitoring stuff. inst.Monitoring = ctxt.resolve(nox.netapps.monitoring.monitoring.Monitoring) Of course you should ensure that the Monitoring module is resolvable, that means, it must be loaded by NOX either by issueing it on the commandline or (which is the cleaner way) it must be declared in the meta.json file of your component as a dependency.

If your install a flow entry without any actions it should cause the datapath to drop the packet.

Re: [nox-dev] Best way to create ARP request
Haven't tested the arp code yet (gotta add the action code from the other issue first). I'll build off of what you suggested in the other email and try and wrap it all together. As a complete aside, my goal is to build an openflow switch that can do transparent redirect of attack traffic either to a honeypot or to an alternate port that has additional options for monitoring and response (more thorough IPS, more restrictive ACLs, etc, etc). White listed traffic would go through the main port and avoid these tools. This allows confidence that critical traffic will get through unhindered while still allowing deployment of advanced (and fallible) security measures. Unfortunately I'm much more of a security guy than I am a programmer =P.

OpenFlow version 2.02 doesn't mean anything to me. What kind of switches are you using? What IP address are you using with dpctl? The switch?

Re: [nox-dev] How to configure an OpenFlow network in in-band mode?
There are multiple ways that you can set up in-band control, and I believe support varies depending on the specific type of switch you're using, so you will probably get a better response by asking the specific switch vendor. (By the way, your message was posted to the list like five or six times. I am guessing this is because you kept getting strange responses because you not only sent to nox-dev, but to nox-dev-request. Please send messages to the list only to nox-dev.) -- Murphy On Feb 28, 2012, at 5:55 PM, chenyangseamoon wrote: Hi, I'd like to configure an OpenFlow network in in-band mode.
