Are DomainKeys for e-mail signing dead?
by Matthew Black 01 Mar '14

01 Mar '14

Apologies if I slept through prior discussions on the topic. E-mail from our L-Soft LISTSERV was recently rejected by Yahoo with the following error: #####(a)YAHOO.COM Last error: 5.7.9 554 5.7.9 Message not accepted for policy reasons. See http://postmaster.yahoo.com/errors/postmaster-28.html I note: 1. The e-mail error (5.7.9) references the link http://postmaster.yahoo.com/errors/postmaster-28.html. 2. That Yahoo page does not mention error 5.7.9, but references a similar error 5.7.4 "Message not accepted for policy reasons." 3. It appears that Yahoo wants inbound messages signed using DomainKeys technology. 4. Yahoo is the lead inventor of DomainKeys, along with Cicso, PGP, and Sendmail. 5. L-Soft LISTSERV manuals and Yahoo both refer to the website http://domainkeys.sourceforge.net/. 6. When I click on the Documentation and DomainKeys Implementors Mailing List links on that page, I get page not found. 7. A 2007 USA Today Article (http://usatoday30.usatoday.com/tech/products/cnet/2007-05-23-domainkeys-ant…) mentions that DomainKeys have not been widely adopted. 8. A basic Google search for DomainKeys comes up with no recent articles. One website (http://blog.wordtothewise.com/2011/09/dkim-is-done/) says that DKIM/DomainKeys are dead. Are the rumors of the death of DomainKeys premature? If not, is anyone from Yahoo listening? matthew black california state university, long beach

Peering issue - Possible Juniper to Cisco issue
by Philip Lavine 28 Feb '14

I had no sync on and a prefix list so I was advertising only one route. Even though I hard reset the session on my end the Telco for some reason kept seeing me send the routes. I finally called them and had them reset their end and the session came up right away. What the ... thx Philip

congestion between Cogent and CenturyLink

Hello, We send periodic 10-15Mbps bursts of traffic to a business partner and it appears to transition from Cogent to Century Link in Atlanta. During the day performance is normal and latency appears acceptable on a trace route. 12 ms 13 ms 12 ms te0-6-1-7.rcr21.msp01.atlas.cogentco.com [38.88.188.41] 26 ms 26 ms 27 ms be2410.ccr22.ord01.atlas.cogentco.com [154.54.7.229] 43 ms 44 ms 44 ms be2099.ccr22.atl01.atlas.cogentco.com [154.54.28.74] 44 ms 44 ms 44 ms be2051.ccr21.atl02.atlas.cogentco.com [154.54.0.162] 43 ms 42 ms 43 ms qwest.atl02.atlas.cogentco.com [154.54.13.30] 49 ms 49 ms 50 ms min-edge-10.inet.qwest.net [205.171.128.154] But after hours latency spikes and throughput drops to less than 1Mbps. te8-3.ccr01.msp01.atlas.cogentco.com (38.88.188.41) 4.603 ms te0-0-0-19.mpd22.ord01.atlas.cogentco.com (154.54.1.230) 17.838 ms be2099.ccr22.atl01.atlas.cogentco.com (154.54.28.74) 33.156 ms be2051.ccr21.atl02.atlas.cogentco.com (154.54.0.162) 36.449 ms qwest.atl02.atlas.cogentco.com (154.54.13.30) 89.583 ms min-edge-10.inet.qwest.net (205.171.128.150) 89.806 ms Century Link stated that Cogent is oversubscribing the link, and that they've requested Cogent resolve the problem, but that action has yet to be taken.

Re: Filter NTP traffic by packet size?

Most of what I've seen are reset configs on network gear, standalone devices (printers), and the occasional win 98 box with network addons. We put blocks in place for ntp, SNMP for a short time to get things under control. Chargen was so small it was easier to just alert folks directly. HTH.
