UDP Amplification DDoS - Help!
by Mitch Dyer 09 Feb '16

09 Feb '16

Hello, Hoping someone can point me in the right direction here, even just confirming my suspicions would be incredibly helpful. A little bit of background: I have a customer I'm working with that is downstream of a 1Gb link that is experiencing multiple DDoS attacks on a daily basis. Through several captures I've seen what appear to be a mixture of SSDP and DNS amplification attacks (though not at the same time). The attack itself seems to target the PAT address associated with a specific site, if we change the PAT address for the site, the attack targets the new address at the next occurance. We've tried setting up captures and logging inside the network to determine if the SSDP/DNS request originate within the network but that does not appear to be the case. We've reached out for some assistance from the upstream carrier but they've only been able to enforce a 24-hour block. I'm hoping someone with some experience on this topic would be able to shed some light on a better way to attack this or would be willing to confirm that we are simply SOL without prolonged assistance from the upstream carrier. Thanks in advance for any insight. Mitch

Arista optics
by Alex Forster 07 Feb '16

07 Feb '16

Hi everyone! I'm trying to get buy-in to go with Arista for some new infrastructure, but the Arista optics just aren't in the ballpark for us at "proof-of-concept" volume. In Cisco-land, we've had great success using Finisar optics, and they've been an easy "sell" to management since many Cisco optics are just rebranded Finisar's. The relevant Arista optics I'm looking at are QSFP-100G-LR4 and SFP-10G-LR. Does anybody know what supplier(s) manufacture these optics for Arista? Alternatively, does anyone have any experience using third-party comparable optics (especially the 100G) in the battlefield? Since optics sales are pretty cut-throat, I do ask that you disclose if you have a financial interest in any of your suggestions. Thanks! Alex Forster

NANOGers - One of the concerns raised at a previous NANOG was with respect to the need for an RPKI relying parties to explicitly accept ARIN's relying party agreement (RPA) - note that this has now been changed (per the attached announcement) Wile the RPA terms remain the same, it is no longer necessary to click-accept and provide an email in order to access ARIN's trust anchor locator (TAL). FYI, /John Begin forwarded message: From: ARIN <info(a)arin.net<mailto:info@arin.net>> Date: February 4, 2016 at 2:54:06 PM EST To: <arin-announce(a)arin.net<mailto:arin-announce@arin.net>> Subject: [arin-announce] RPKI Relying Party Update In response to community feedback, entities wishing to become relying parties and utilize ARIN's Trust Anchor Locator (TAL) and Resource Public Key Infrastructure (RPKI) repository information will no longer be required to "click to accept" ARIN's Relying Party Agreement (RPA) before doing so.
