Hi, I'm a freshman of Openflow and Nox. I want to make a demo about customized
routing control,
but there are something I'm confused. For example, I have a network topology
consisting of 3 switches(
Switch A, Switch B, Switch C), making up a triangle. We also have a host "Host
A" connected to S
Thanks Murphy!
You're right, that did the trick.

So I think the call to l3.checksum() is extraneous, but the real issue is
probably that l3.iplen should be ipv4.MIN_LEN + l4.len.

Hi Murphy,
wow... Opps...
I'm trying the following: This doesn't return any errors but in
wireshark the packet_outs say Malformed UDP packets.
def send_udp_message():
l4 = udp()
l4.srcport = 1999
l4.dstport = 1888
l4.len = udp.MIN_LEN + len("hello_world")
l4.set_payload("Hello_wo
Ok, you are right.I refered http://noxrepo.org/noxwiki/index.php/NOX_Installation#Installationso, git clone git://noxrepo.org/noxcd noxgit branch -agit checkout -b destiny origin/destiny./boost.shmkdir build/cd build../configuremake -j 5and thenI can see monitoring directory.src/nox/netapps#
Unfortunately, your tweak breaks the logic of the assert.
The assert is asserting that self.next is a packet_base of some sort OR a
string. You've set it to a string, so... it should be a string. So it should
definitely not be a packet_base. So the first of your asserts will always
fail.
Hi Murphy,
I'm using zaku but the one in destiny looked the same to be.
I changed to assert to be on two lines so I could see which one was firing.
def checksum(self):
#assert(isinstance(self.next, packet_base) or type(self.next)
== type(''))
assert(isinstance(self.next, pack
What NOX are you using? Your udp.py does not seem to be the one in zaku or
destiny...

Hello,
I was able to successfully craft my UDP packets using scapy and then
pass that to send_openflow_packet() and that seemed to do the trick
for me. (I'm this curious what my issue is with building the packet up
using nox though).
def send_udp():
packet = scapy.Ether(type=0x800, dst="00:0
I see if I put
a = packet_base()
l4.next = a
That gets me around the first part of the assertion but then I get asserted on:
assert(type(self.next) == type(''))
Thanks,
Aaron

Hi,
you are probably using the branch of the repository and not destiny. Take a
look at the first reply above, which explains that the monitoring component
is only on the Destiny branch, and how to get it.
(Using Destiny is suggested at this point, as it is more up-to-date version
of nox with sev

Hi,after I found monitoring.py,There is existing /src/nox/coreapps/examples/monitor.py.I think what you mean is /src/nox/coreapps/examples/monitor.py. right ?so, I excuted monitor component.I can check Table stats and Port stats, Aggregate stats as a below.00072|openflow-event|DBG:received s
