Microsoft missing public DNS TXT entry for DKIM records (msn.com)
by Adam Brenner 04 Apr '24

04 Apr '24

Apologies if this message is the wrong listserv to ask this question but we are scratching are heads here. We run our own exim mail server and are receiving reports of end users getting bounce back messages when they send email from msn.com to our mail server. Our mail server checks if DKIM email headers are present and if they are, tries to validate them. If the check fails, we reject the message. We are noticing that Microsoft, specifically, msn.com, does *not* publish DKIM DNS text records but sends email with the DKIM email headers. Is this normal or correct? Anyone have information or a contact at Microsoft that can fix this -- publish their DKIM records? It seems to me that if msn.com is going to include DKIM headers in their outgoing email, they should also publish their DKIM public key. If they are not going to publish their DKIM public key, then they should not include DKIM headers in their outgoing email. Other Microsoft email accounts and services such as hotmail.com and outlook.com publish their DKIM records. Again, it seems msn.com should as well. If we look at a bounce back messages we see the following snippet: Generating server: PH7PR84MB1704.NAMPRD84.PROD.OUTLOOK.COM ... Remote server returned '550 5.0.350 Remote server returned an error -> 550 DKIM: encountered the following problem validating msn.com:;pubkey_unavailable' Original message headers: ... DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/relaxed; d=msn.com; s=selector1; ... When we try and perform a TXT DNS query to fetch the DKIM record: selector1._domainkey.msn.com we see that Microsoft does *not* publish their DKIM records: adam@defiant ~ $ dig selector1._domainkey.msn.com TXT ; <<>> DiG 9.18.25 <<>> selector1._domainkey.msn.com TXT ;; global options: +cmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 13050 ;; flags: qr rd ra; QUERY: 1, ANSWER: 2, AUTHORITY: 1, ADDITIONAL: 1 ;; OPT PSEUDOSECTION: ; EDNS: version: 0, flags:; udp: 65494 ;; QUESTION SECTION: ;selector1._domainkey.msn.com.

Hi Network Experts, Is anyone using Unimus as your main NCM tool in production? I am looking at an NCM tool that can scale upto 10,000 to 15,000 Network Devices. Do you recommend any other solution? The solution should atleast able to support network config backups, diffs, and basic network auditing features. https://unimus.net/ thanks Shahid

SRI's Dan Lynch dies

02 Apr '24

>From Lauren Weinstein @ PRIVACY Digest: """ Dan Lynch, one of the key people involved in building the Internet and ARPANET before it, has died. Dan was director of computing facilities at SRI International, where ARPANET node #2 was located and he worked on development of TCP/IP, and where the first packets were received from our site at UCLA node #1 to SRI, and later at USC-ISI led the team that made the transition from the original ARPANET NCP protocols to TCP/IP for the Internet. And much more.

Call for Participation -- ICANN81 DNSSEC and Security Workshop for ICANN Policy Forum
by Jacques Latour 02 Apr '24

02 Apr '24

Call for Participation -- ICANN DNSSEC and Security Workshop for ICANN Policy Forum In cooperation with the ICANN Security and Stability Advisory Committee (SSAC), we are planning a DNSSEC and Security Workshop for the ICANN80 Policy Forum being held as a hybrid meeting from 10-13 June 2024 Kigali, Rwanda in the Central Africa Time - CAT (UTC +2). This workshop date will be determined once ICANN creates a block schedule for us to follow; then we will be able to request a day and time. The DNSSEC and Security Workshop has been a part of ICANN meetings for several years and has provided a forum for both experienced and new people to meet, present and discuss current and future DNSSEC deployments. For reference, the most recent session was held at the ICANN79 The Community Forum on Wednesday, 06 March 2024. The presentations and transcripts are available at: https://icann79.sched.com/. The DNSSEC Workshop Program Committee is developing a program for the upcoming meeting. Proposals will be considered for the following topic areas and included if space permits. In addition, we welcome suggestions for additional topics either for inclusion in the ICANN78 workshop, or for consideration for future workshops. 1. Global DNSSEC Activities Panel For this panel, we are seeking participation from those who have been involved in DNSSEC deployment as well as from those who have not deployed DNSSEC but who have a keen interest in the challenges and benefits of deployment, including Root Key Signing Key (KSK) Rollover activities and plans. 2. DNSSEC Best Practice Now that DNSSEC has become an operational norm for many registries, registrars, and ISPs, what have we learned about how we manage DNSSEC? * Do you still submit/accept DS records with Digest Type 1? * What is the best practice around key roll-overs? * What about Algorithm roll-overs? * Do you use and support DNSKEY Algorithms 13-16? * How often do you review your disaster recovery procedures? * Is there operational familiarity within your customer support teams? * What operational statistics have been gathered about DNSSEC? * Are there experiences being documented in the form of best practices, or something similar, for transfer of signed zones? Activities and issues related to DNSSEC in the DNS Root Zone are also desired. 3. DNSSEC Deployment Challenges The program committee is seeking input from those that are interested in implementation of DNSSEC but have general or concerns with DNSSEC. We are seeking input from individuals that would be willing to participate in a panel that would discuss questions of the following nature: * Are there any policies directly or indirectly impeding your DNSSEC deployment? (RRR model, CDS/CDNSKEY automation) * What are your most significant concerns with DNSSEC, e.g., complexity, training, implementation, operation, or something else? * What do you expect DNSSEC to do for you and what doesn't it do? * What do you see as the most important trade-offs with respect to doing or not doing DNSSEC? 4. Security Panel The program committee is looking for presentations on DNS, DNSSEC, routing and other topics that could impact the security and/or stability of the Internet. We are looking for presentations that cover implementation issues, challenges, opportunities, and best practices for: * Emerging threats that could impact the security and/or stability of the Internet * DoH and DoT * RPKI (Resource Public Key Infrastructure) * BGP routing & secure implementations * MANRS ( Mutually Agreed Norms for Routing Security) * Browser security – DNS, DNSSEC, DoH * EMAIL & DNS related security – DMARC, DKIM, TLSA, etc… If you are interested in participating, please send a brief (1-3 sentence) description of your proposed presentation to dnssec-security-workshop(a)icann.org<mailto:dnssec-security-workshop@icann.org> by COB Friday, 10 May 2024. Thank you, Jacques On behalf of the DNSSEC Workshop Program Committee: Steve Crocker, Edgemoor Research Institute Mark Elkins, DNS/ZARC Jacques Latour, .CA Russ Mundy, Tislabs Yoshiro Yoneya Dan York, Internet Society

N91 Women mixer on Sunday?
by Ilissa Miller 02 Apr '24

02 Apr '24

For those that know me, I rarely provide constructive input about NANOG matters due to my past affiliation, however, I just saw that NANOG announced the Women mixer on Sunday before NANOG 91 and am outraged for all of the young professional women who would like to participate in NANOG. While the times are changing, women continue to remain primary caregivers for families and this will require them to desert their families a day early. I find it offensive personally and feel like you may have missed the mark. The amount of times I hear people complain about having to leave their families is one of the reasons this industry has a problem keeping young people - especially women. Does anyone else feel the same? -- *Ilissa Miller* *CEO, iMiller Public Relations <http://www.imillerpr.com>*

March is International Women's History Month - Remembering Betty J. Burke!
by Ilissa Miller 29 Mar '24

29 Mar '24

In honor of Women’s History Month, Ilissa Miller <https://www.linkedin.com/in/ilissamiller/>, Founder and CEO of iMiller Public Relations (iMPR) <https://www.imillerpr.com/>, and Jezzibell Gilmore <https://www.linkedin.com/in/jezzibell/>, would like to recognize Betty Joe Burke, former Executive Director for NANOG <https://www.nanog.org/> – the North American Network Operators’ Group. Miller reflects on the profound impact Betty had on her life and career: If you don’t know of Betty – who passed away on November 7, 2022 – she was a firecracker and an industry starter enabling the accelerated development of the internet across the U.S. Betty spent her professional career as an IT trailblazer. She worked to “bring people together” to develop the Internet first through her work at the University of Michigan beginning in 1974, later through Merit Network, Inc. and as the Executive Director of the North American Network Operators’ Group (NANOG, Inc.). Her professional endeavors included management of a consortium of engineering professionals working to re-engineer and manage the first national, high speed internet backbone (NSFNET). She oversaw the build out of the State of Michigan’s largest technology center and coordinated IT conferences composed of an international membership community working to invent the Internet of tomorrow. She retired from the University of Michigan after 36 years of service in 2010. She retired as the Executive Director of NANOG, Inc. in 2018. I had the honor and pleasure of working side-by-side with Betty from 2012-2018 while overseeing sponsorship sales for NANOG. She was a mentor, a friend, a colleague and a boss – she embodied everything I always thought a leader should be. I miss her dearly. Please join me in honoring Betty Joe Burke during this March 2024 in honor of Women’s History Month! Gilmore emphasizes the incredible spirit that Betty embodied, being a driving force in the industry, while still empowering and motivating others. Gilmore recalls Betty’s soft tone of voice, calming smile, and unwavering determination that has since left a lasting impact on the internet industry: Betty was an incredible spirit who was deeply loved and respected by many in the Internet networking industry. Betty Joe Burke is an unsung hero, and one deserves much more admiration and praise for what she has done throughout her career. While our lives are our own, often the path we take is shaped by people and events in our lives. Betty is one of those quiet yet powerful leaders, whose influence shaped the Internet networking industry, and the paths of many that built the industry. Her soft tone of voice, calming smile no matter the situation, and unwavering determination not only paved the way for our generation of women leaders, but generations of talent and mindset of the internet industry. Betty was kind, passionate, persistent, creative, intelligent, and hard working. Although she took charge, she did not like to be the center of attention. She demonstrated daily success comes from relentless pursuit of your goals, not knowing how to do everything. One of the phrases that she used often, that I now use myself all the time is “We’ll figure it out”. Because she always figured out a way to make it happen. Betty was talented in many aspects, but above all else, she took the time to build up people around her. She not only encouraged me to take risks that I was too afraid to take, but she was by my side to support and guide me along my entire NANOG leadership journey. I didn’t just learn how to be a better communicator, but how to introspect and elevate my point of view as a leader. Betty was courageous. Courage is actions taken while acknowledging our fear, and in spite of that fear. Betty taught me not to fall victim to fear, especially fear of failure – don’t allow fear of failure keep you from taking actions. Our actions define who we are, not our thoughts or intentions. I am a better version of me because of the actions I had taken at Betty’s urging. Betty is deeply missed by her colleagues, family, and friends who cherish her memory and the enduring impact she made on the industry, ensuring that her influence will continue to resonate for generations to come. This Women’s History Month, please join us in honoring Betty Joe Burke by reciting the poem she chose for her celebration of life: You can read the post online here: https://datacenterpost.com/honoring-betty-joe-burke-women-of-the-global-dig…
