Early Stages of Product Decline

One of the worst things that can happen to anyone selecting equipment for a new network infrastructure is to receive the End-of-Life notice a week after the gear has been deployed in a production network… or maybe it’s even worse to be stuck with a neglected piece of technology full of bugs that the vendor never fixes because they’re chasing other shinier squirrels.

If you’re careful and watch what the vendors are doing, you might be able to save the day and identify the early phases of product decline. Here they are (as seen from the outside) in approximate order:

End of promotion opportunities. In most corporations aggressive hunters fare better than meticulous farmers, and product development is no different. As a friend of mine working for a large corporation once said “The culture here rewards launches instead of steady improvements. Like in academia, publishing a paper is valued more than running ISS”.

Windows Server vulnerability disclosed by NSA; Don’t wait to patch

Microsoft’s monthly Patch Tuesday included a hefty haul of fixes: 49 total, and one of them is more than just critical. For enterprises running Windows Server 2016 and Server 2019, it's vital you implement the patch ASAP.The National Security Agency (NSA) disclosed the Windows vulnerability on Tuesday, the same day the fix was issued. That means the NSA found the flaw likely months ago but held off on public notification until Microsoft could come up with a fix. It would be irresponsible for the NSA, or anyone else, to announce a vulnerability and not give the software maker time to patch it.The vulnerability was spotted in "crypt32.dll," a Windows module that has been in both desktop and server versions since NT 4.0 more than 20 years ago. Microsoft describes the library as handling certificate and cryptographic messaging functions in the CryptoAPI.To read this article in full, please click here

Loodse Steers Telco 5G Plans Toward Kubernetes

MacOS Catalina = Windows Vista

Remember the Windows version that was so security-focused that it broke everything, and needed a gazillion changes/updates/upgrades to get back to where you had a working computer? I think it was Vista, but maybe my memory is failing me. Anyway, Apple got its Vista moment with macOS Catalina.

I was stupid enough to upgrade just before New Year, and I’m still struggling with aftereffects and skeletons falling out of every cupboard I look at. I appreciate Apple trying to make their operating system ever more secure, but breaking stuff every time I upgrade it is borderline ridiculous.

QFX Upgrades – Check Host Version

I came across a situation where a software upgrade failed for some members in a Juniper QFX Virtual Chassis. There is a known issue with upgrades with a certain configuration + version combination, but I thought it didn’t apply to me. Turns out that the key was the host OS version, not the Junos VM version. Your host and guest versions can be out of sync with Juniper QFX 5K devices, and this can lead to confusing behavior, especially in a virtual chassis where host OS versions might vary.

Upgrade Failures - post-install error

When upgrading an old Juniper QFX5100, you might see these messages when running the upgrade:

1
2
Error: jinstall-vjunos fails post-install
Error: jinstall-vjunos-14.1X53-D34-domestic-signed fails post-install

In my case, I saw it for some nodes in a Virtual Chassis. Some worked, some failed. KB31923 says that this error is due to this configuration:

1
2
3
# show system internet-options
tcp-drop-synfin-set;
no-tcp-reset drop-tcp-with-syn-only;

Easy enough to change:

1

# delete system internet-options
{master:0}[edit]

Heavy Networking 498: Creating A Single Source Of Truth For Network Automation

For network automation you need a single source of truth that’s programmatically accessible, reflects intended state, and enables others to stand up infrastructure correctly without you getting in the middle of every provisioning request. Tim Schreyack joins us today to discuss network automation approaches using Ansible and Python, and of course, a single source of truth.

Pacific Report to the Dynamic Coalition of Small Island Developing States in the Internet Economy

2019 was an active year for Pacific involvement in the Internet economy. What we have demonstrated is that originating from small island developing states (SIDS) in the Pacific does not restrict one’s opportunity to become a leader within large international organizations like ICANN, which manages and allocates domain names and IP addresses globally.

I was very honored that my colleagues from the ICANN At-Large Advisory Committee (ALAC) elected me to be their Chair for 2019, and again for the upcoming year. It has enabled me to use my organizational management skills which I did by distance learning from Rarotonga through Massey University in New Zealand.

My Cook Islands colleague, Pua Hunter, was also elected at the recent ICANN meeting as regional co-chair for the Government Advisory Committee (GAC). She is already the chair of GAC’s Underserved Regions Committee. Such leadership roles have also been achieved by others from SIDS in other Internet-related organizations, which goes to show that being from small islands does not mean that we will go unnoticed if we are prepared to be active in our commitment to improving our regions.

The Pacific Islands Chapter of the Internet Society (PICISOC) received a boost at the elections last Continue reading
