IPV6 issue
by Steve Clark 20 Dec '11

20 Dec '11

Hello, I have a SIXXS ipv6 tunnel that terminates in Ashburn, Va. I have two HE ipv6 tunnels, one terminates in Dallas the other terminate in Ashburn. I can ping each endpoint of the tunnels that terminate in Ashburn, but I can't ping between the SIXXS and HE with the HE termination in Dallas. Using Looking Glass at HE I can traceroute to my SIXXS tunnel from Chicago but not from Dallas. Any ideas on how to get this fixed. This problem only started occurring within the last week or so. Thanks for your indulgence, -- Stephen Clark *NetWolves* Sr. Software Engineer III Phone: 813-579-3200 Fax: 813-882-0209 Email: steve.clark(a)netwolves.com http://www.netwolves.com

Re: Nexus emulation? Anyone?

You couldn't use Titanium to judge/discuss the nexus family as a whole either. Aside from 1KV, all the nexus products use ASIC hardware specific to that platform/linecard and no NXOS software emulator exists that mimics those behaviors. 2 cents, Tim At 09:34 AM 12/20/2011, Luan Nguyen gushed: >You can't use the software switch Nexus 1000V to judge/discuss the Nexus >family products N7K, N5K...etc as a whole? > >Check out this discussion ><https://supportforums.cisco.com/thread/2054884>https://supportforums.cisco.com/thread/2054884 > >Titanium as they call the NX-OS simulator is not available to the public >though... > >-Luan > >On Tue, Dec 20, 2011 at 12:08 PM, -Hammer- <bhmccie(a)gmail.com> wrote: > > > Bah.

software wanted
by Gregory Edigarov 20 Dec '11

20 Dec '11

Hi everybody, can anybody recomend a piece of software, that could "graph" a live network scanning it via snmp. requirements are: 1. must produce a text output suitable for postproduction. graphviz is an ideal, xml - acceptable. 2. must use no external database i.e. have text config file. clean text console, suitable to run as a cronjob. 3. must be able to work in heterogenous environment. thanks a lot in advance -- With best regards, Gregory Edigarov

EIther way, the blackhat still has to hack the machine and modify the config. The only difference is what config change they make.

Nexus emulation? Anyone?
by -Hammer- 20 Dec '11

20 Dec '11

I know we can't throw NX code on Dynamips but I figured I would ask the group anyway. We are starting to discuss Nexus platform options and I can only get so much from demo depot before our AM gets whiny. Is anyone currently emulating Nexus on anything that is open to the public? Not I.O.U. but Dynamips or something similar? If the software is out there I have the hardware to support it. Based on some cheap googling I'm thinking the answer will be no. Although I did find Greg Ferros public outcry for network emulators from last year.... -- -Hammer- "I was a normal American nerd" -Jack Herer

Overall Netflix bandwidth usage numbers on a network?
by Jonathan Towne 20 Dec '11

20 Dec '11

Been lurking for a while and posed a question to a few folks without much response, figured someone here might've done something like this already. So, before I go about building wheels that already exist: I'm interested in doing a bit of a passive survey of bandwidth usage on my network (smallish isp, a few thousand DSL/FTTx customers) to understand the percentage of average/overall traffic generated by Netflix streaming. What I have available is a few gigabit transport switches providing me with mirror ports, a juniper MX series router running 10.4 code, plenty of BSD machines and libpcap-fu. What I'm looking for is either a timed-average or moments-glance number of the traffic. For instance, on an interface moving 150mbit/sec total, 50mbit/sec of it is attributed to Netflix right now. I'm pretty handy with RRDtool, so that isn't out of the question, either. I've really only spent dinnertime considering this, but have come up with two potential approaches so far, and haven't actively investigated either of them: * firewall terms and counters on the MX router + snmp * writing a quick libpcap application to filter and count in a completely out-of-band way on one of my monitoring hosts Some challenges I can see: * Nailing down the streaming source for Netflix, that is, IP ranges etc. * Making assumptions about CDN source IPs that could be used for something else, and further, should I care? Happy to hear thoughts about this, helpful or not! I know Netflix themselves have probably done plenty of studies like this, but pretty likely not limited to my customer base. Not aiming for anything creepy or crazy, just some vague understanding of what's going on, and the ability to do some trending for future planning. -- Jonathan Towne

ipv6.level3.com responding with a "500 Internal Server Error" for 3+ days
by Frank Bulk 20 Dec '11

20 Dec '11

ipv6.level3.com has been responding with a "500 Internal Server Error" since Saturday morning. I reached out twice to the NOC email address I have on file, but no response. Perhaps someone can reach out to the right person. Frank P.S.: ipv6.cnn.com has not been responding properly for about two-thirds of this month, starting December 7, early a.m. I've reached out to my Turner contact at least twice, but not luck there, either.
