[nox-dev] NOX compilation error
I recently tried a fresh NOX installation from the noxrepo git repo on Ubuntu 10.04. ./configure --with-python=yes fails with an error: configure: error: Could not link against ! The last few lines of the output are: checking for g++ option to produce PIC... -fPIC -DPIC checking if g++ PIC flag -fPIC -DPIC works... yes checking if g++ static flag -static works... yes checking if g++ supports -c -o file.o... yes checking if g++ supports -c -o file.o...

This is most likely not a NOX problem, as I have compiled the source multiple times in the past, but on Debian machines. If anyone has encountered a similar problem on Ubuntu and managed to fix it, please let me know. Thanks, Nikhil ___ nox-dev mailing list nox-dev@noxrepo.org http://noxrepo.org/mailman/listinfo/nox-dev_noxrepo.org
[nox-dev] dropping packets
Hi Everyone, I am running NOX and openflow on the same machine. I am coding the NOX controller in C++. I am trying to write code to selectively drop packets. For a quick test I tried to write code that would drop HTTP (i.e. tcp dst port 80) packets. The code correctly identifies the HTTP packet and it calls the send_openflow_command with no action. However the packets are not getting dropped. Below is initialisation of the openflow mod structure. Which is sent in the command. // setup the header ofm.header.version = OFP_VERSION; ofm.header.type = OFPT_FLOW_MOD; ofm.header.length = htons(sizeof ofm); // no extended action data // match the flow - therefore no wild-cards! ofm.match.wildcards = htonl(0); ofm.match.in_port = htons(flow.in_port); ofm.match.dl_vlan = flow.dl_vlan; memcpy(ofm.match.dl_src,flow.dl_src.octet,sizeof ofm.match.dl_src); memcpy(ofm.match.dl_dst,flow.dl_dst.octet,sizeof ofm.match.dl_dst); ofm.match.dl_type = flow.dl_type; ofm.match.nw_src = flow.nw_src; ofm.match.nw_dst = flow.nw_dst; ofm.match.nw_proto = flow.nw_proto; ofm.match.tp_src = flow.tp_src; ofm.match.tp_dst = flow.tp_dst; // add an entry - initalise entry housekeeping variables (see page 28 of OF spec) ofm.command = htons(OFPFC_ADD); ofm.buffer_id = htonl(packetid); ofm.idle_timeout = htons(OFP_FLOW_PERMANENT); ofm.hard_timeout = htons(OFP_FLOW_PERMANENT); ofm.priority = htons(OFP_DEFAULT_PRIORITY); ofm.flags = OFPFF_CHECK_OVERLAP; When I run dpctl dump-flows on the switch I get cookie=14431522174269325312, duration_sec=15s, duration_nsec=83200s, table_id=0, priority=65535, n_packets=3, n_bytes=222, idle_timeout=0,hard_timeout=0,tcp,in_port=1,dl_vlan=0x,dl_vlan_pcp=0x00,dl_src=00:07:e9:ae:04:c7,dl_dst=00:13:d3:c0:46:f2,nw_src=192.168.1.1,nw_dst=91.189.88.31,nw_tos=0x00,tp_src=58891,tp_dst=80,actions= Any ideas on what I am doing wrong? thanks in advance Iain ___ nox-dev mailing list nox-dev@noxrepo.org http://noxrepo.org/mailman/listinfo/nox-dev_noxrepo.org
Re: [nox-dev] dropping packets
Hi guys, I don't think I made it clear in the previous post. The code in the previous post only gets called when the flow is identified as HTTP. Then I am trying to block that particular flow. I know it would make more sense to write general rule and send the command from the install method. I am just doing this initially to see if I can get any packets dropped.

Re: [nox-dev] dropping packets
Hi Ricardo and ikf, Thanks for the refresh. I think ikf was trying to install the flow entry and it is not matching for some reason. But the refresh is definitely useful. Btw, I am replying just to correct a typo. You should return STOP to drop the packets, not CONTINUE. And do check nox.xml or nox.json in src/etc to ensure the order of the component being called by Packet_in_event. It is always cool to see the community chipping in. Allow me to say thanks to everyone that have done so, and hope others will help out too. THANKS. Regards KK On 12 July 2010 08:37, Ricardo Bennesby ricardo.benne...@gmail.com wrote: Hello ikf.

Re: [nox-dev] [installation-problem] undefined refrence
Dear All, I am still getting this error while installing the NOX. I have checked that xerces is installed successfully. You can see the outcome of the previous post. Now I have to set the path of the libraries. I found that libraries are in that path /home/xerces-c-3.1.1/src/.libs. so I tried to set the path by this command export LD_LIBRARY_PATH=/home/xerces-c-3.1.1/src/.libs and when I run make to install NOX on debian virtual machine.

Re: [nox-dev] dropping packets
Hi KK. Thank you for reply. But just to have sure, in the pyswitch.py component there are originally in lines 140-149: * # don't forward lldp packets if packet.type == ethernet.LLDP_TYPE: return CONTINUE # learn MAC on incoming port do_l2_learning(dpid, inport, packet) forward_l2_packet(dpid, inport, packet, packet.arr, bufid) return CONTINUE * Doesn't it mean that the lldp packets are dropped, because no actions are specified and they are not forward? Thanks again. I agree with you when you say that the community participation is very important. If I'm wrong, please correct me.

Re: [nox-dev] dropping packets
Hi, Yes. return CONTINUE passes it to the next component and return STOP prevents the next component from getting it. This is true for both C/C++ components and Python components.

[nox-dev] nox
First of all, I would like to introduce myself that I am Vu Huong, an undergraduate of Faculty of Electronics and Telecommunications, Hanoi University of Technology in Vietnam. I am in charge of researching about NOX in open flow network, such as, module of nox, module that has someone setting up, However, I haven't got much experience in the issue since I have just started the project for a short time. As I have found you and your expertise from the website noxrepo.org, it would be great if you could do me a favor: where should I start? which of reference should I study,for example, white paper, website... Thank you very much in advance I am looking forward to your response Best regards, Vu Huong ___ nox-dev mailing list nox-dev@noxrepo.org http://noxrepo.org/mailman/listinfo/nox-dev_noxrepo.org
Re: [nox-dev] Trouble during make
I think this problem is just due to nox 0.5 (in the noxcore repo) not supporting xerces 3. This was addressed in nox 0.6. And in the future, the dependency on xerces will be removed. So any way you slice it -- yes, this has been resolved. If for some reason you really need nox 0.5, you can just install and build against xerces 2 (you may have to point at it when you run configure if you leave xerces 3 installed). Or -- since it doesn't look like the interface has changed at all -- you should be able to just copy the nox 0.6 version of xml-util.cc into nox 0.5. -- Murphy On Mon, 2010-07-12 at 11:36 -0700, Nikhil Handigol wrote: Has this issue been resolved?
