Re: Network Storage
by Joel M Snyder 12 Apr '12

12 Apr '12

>Can you please comment on what is best solution for storing network >traffic. Well, "best" is kind of a hard word to use here. There are lots of different solutions depending on exactly why and where you want to capture this. As far as I know, there are really two credible companies who are thrashing it out in this space right now, NetWitness (now part of RSA) and Solera. I think that Niksun is still out there, but they haven't done much recently or maybe they just concentrate on particular sectors and so I never see them. Of course, you can also just tcpdump it yourself, but the commercial products do a lot of the metadata analysis and creation for you, so it's a lot easier to understand what is happening in your traffic than just having piles of tcpdumps. I bought a NetWitness box and was profoundly unimpressed. So I guess my advice would be to start with Solera and then look at NetWitness if you don't like Solera. This assumes you have budget. If this is a back-of-the-envelope "hey, let's grab some packets and do something with them" kind of exercise, then filter your tcpdumps a lot better. jms -- Joel M Snyder, 1404 East Lind Road, Tucson, AZ, 85719 Senior Partner, Opus One Phone: +1 520 324 0494 jms(a)Opus1.COM http://www.opus1.com/jms

Re: Level3 IPv6 peering with HE only in London?
by Dave Sotnick 12 Apr '12

Yep, looks much better now. This is what Level3 had to say: "David, You should see this repaired at this time, looks like the peering between L3 and HE crashed in stateside when the ipv6 max prefix limits exceeded the router configurations. Please let us know if any further questions.
