Visualizing Application Flows with xtractr
by kowsik 01 Oct '10

01 Oct '10

One of the challenges of troubleshooting networks with packet captures is that you quickly lose the bigger picture with the volume of data. And static reports just don't do justice to the flurry of activity on networks. We just posted a video on visualizing application flows using xtractr. You can learn more about xtractr here: http://www.pcapr.net/xtractr http://labs.mudynamics.com/2010/09/30/visualizing-application-flows-with-xt… K. --- http://www.pcapr.net http://twitter.com/pcapr http://labs.mudynamics.com

RIP Justification
by Jesse Loggins 01 Oct '10

01 Oct '10

A group of engineers and I were having a design discussion about routing protocols including RIP and static routing and the justifications of use for each protocol. One very interesting discussion was surrounding RIP and its use versus a protocol like OSPF. It seems that many Network Engineers consider RIP an old antiquated protocol that should be thrown in back of a closet "never to be seen or heard from again". Some even preferred using a more complex protocol like OSPF instead of RIP. I am of the opinion that every protocol has its place, which seems to be contrary to some engineers way of thinking. This leads to my question. What are your views of when and where the RIP protocol is useful? Please excuse me if this is the incorrect forum for such questions. -- Jesse Loggins CCIE#14661 (R&S, Service Provider)

Frontier DSL Contact
by Tony Bunce 01 Oct '10

01 Oct '10

Can someone from Frontier DSL (formally Verizon) please contact me off list? It appears Frontier DSL customers (at least in Ohio) can't access websites that we host. I have tried contacting the ISIS NOC, the Ohio NOC and the MCO and they were unable to assist. Or if there is anyone on the list using Frontier DSL if they could send me a traceroute to 208.2.209.110 and/or 208.2.213.96 that might also help me track down the issue.

Re: RIP Justification
by Guerra, Ruben 01 Oct '10

01 Oct '10

I am with Scott on this one.. I took the initial question as a focus on the edge... not the CORE. RIP is perfect for the edge to commercial CPEs. Why would want to run OSPF/ISIS at the edge. I would hope that it would be common practice to not use RIP in the CORE.... peace -- Ruben Guerra --------- Sent from my Nokia N900 ----- Original message ----- > Haha It's all good :) > You are right about IS-IS being less resource intensive than OSPF, and > that it scales better! > > > > On 30 September 2010 23:50, Jack Carrozzo <jack(a)crepinc.com<mailto:jack@crepinc.com>> wrote: > > > > > > > > Both OSPF and IS-IS use Dijkstra.

(cisco, or any) acl *reducers* out there?
by George Michaelson 01 Oct '10

01 Oct '10

I have been looking at acl management s/w in the freecode space and I can find lots of tools which manage/distribute and test ACLs in routers. I'm wondering if anyone has written a parser which can construct rule-trees and get rid of the cruft, unusable, order-misorder and other issues in a large ACL pool? Its possible this is NP in the wider sense, but even a partial improvement would be useful something which can take a couple of hundred basic and extended ACLs and tell you these <ten> don't work these <twenty> conflict the remaining <x> have a sequence and can reduce to this basic <x-y> set (we've got the usual "acquisition of rule by accretion" problem across 4 edge/core routers with a mix of public facing, internal, WiFi, guest rules, and I hate to think this is either start from scratch, or intractable. The evidence is that its FRAGILE) -G
