Re: [nox-dev] Not able to send ARP Reply in C++
Hi,Murphy! Thank you for your reply! I look at arp.hh source code. But, my question is not addressed. I forgot to tell you the code I want to write... The code is NAT program. In the NAT, the condition is that arp reply should be addressed. I examined which api to send arp reply by using of Nox(zaku) in C++, and I get a hint from attached Nox sample code switch.cc. The hint is Packet_in_event... Then I want to tell you how to get packet data from Packet_in_event instance. Please give me a hint!

[nox-dev] Why does NOX Destiny version lack of SQLite3 database support??
hi, guys I intend to develop programs based on destiny or latest source codes. Whereas, I find that the version of Destiny lack of SQLite3 database support. Destiny or latest codes only include codes of Dht storage, but Dht storage is too complex for me. Previously, I found that Nox-0.5.0~full~beta version has supported SQLite3. Are there any reasons to remove sqlite3 in the latest codes? Looking forward to your reply. ___ nox-dev mailing list nox-dev@noxrepo.org http://noxrepo.org/mailman/listinfo/nox-dev
Re: [nox-dev] Spanning Tree Module
Hi, ok, I got it to work now. It was a problem on our side. In fact, the switches in the lab are connected by an HP ProCurve switch, which i have configured to use VLANs for every link between the OpenFlow switches. After configuring the HP switch in the correct way, everything worked :) So, I read in the wiki, that the Spanning Tree module was only tested with three switches. I can confirm it works flawlessly with six switches. Thanks for your quick answer. Best regards Bernd Zitat von Murphy McCauley jam...@nau.edu: AFAIK, this should work. Have you actually inspected the switches? Are the relevant ports actually getting NOFLOOD set? -- Murphy On Nov 29, 2011, at 7:54 AM, Bernd Wittefeld wrote: Hi, first of all: thanks for your great work and the really good support here. I have a small problem and I hope someone knows what to do :) The situation is the following: I have a network with 6 OpenFlow switches in a mesh here. The software (switches and NOX) is working fine. I use the spanning_tree module in order to prevent loops in the network when flooding ARP-Requests and stuff. I got everything to work fine and even the NOX Gui (I'm on destiny) shows me a correct Spanning-Tree without loops. I have two hosts which are connected to two different switches. If I send an ICMP ping from one host to the other, I get the ARP requests in the Openflow network. They travel along the spanning tree which I checked by using wireshark and tcpdump. The other links don't show ARP requests. Now the problem: The ARP requests are not forwarded out of the OpenFlow network. That means, they reach the switch that is connected to the destination host, but the host does not get the ARP request. How can I solve this? Do I have to manually unset the NOFLOOD switch on that port in my controller or is there any other way, maybe to make the spanning_tree module more intelligent or am I doing something wrong?

Re: [nox-dev] Why does NOX Destiny version lack of SQLite3 database support??
It was removed several years ago... I think just because nothing in NOX itself was using it. What do you want to use it for? If you just want to use sqlite for your own component to keep data, you can just include it yourself... -- Murphy On Nov 30, 2011, at 6:45 AM, dongxia pan wrote: hi, guys I intend to develop programs based on destiny or latest source codes.
