Heavy Networking 616: Do We Need An SMTP Alternative? TMTP And MNM Are Here To Find Out
The SMTP protocol isn't broken, but email kinda is. Spam, phishing, and other unwanted messages are easy to deliver and harder to stop. On today's Heavy Networking we discuss TMTP and mnm, a proposed new protocol and client that aim to preserve the benefits of email while eliminating vulnerabilities and offering a better experience. Our guest is Liam Breck, creator of TMTP and mnm.

This article was originally published in Packet Pushers Ignition on March 23, 2021. Just as nature abhors a vacuum and seeks to fill it with any available matter, business abhors a single-source solution to wide scale problems. Competitors rush to fill the vacuum of choice with alternative, interchangeable products. The IT market typically fosters competition […]

Backing Up the Dump Truck
Hello Ellen,
I have received a number of these spam messages over the past few weeks and I had hoped they would eventually taper off. However, it doesn’t appear that is the case. So I’ll take the direct approach.
I’m a member of the CCIE Advisory Council. Which means I am obligated to report any and all attempts to infringe upon the integrity of the exam. As you have seen fit to continue to email me to link to your site to promote your test dumps I think you should be aware that I will be reporting you to the CCIE team.
Good luck in your future endeavors after they shut you down for violating their exam terms and conditions. And do not email me again.
That’s an actual email that I sent TODAY to someone (who probably isn’t really named Ellen) that has been spamming me to link to their CCIE dump site. The spam is all the same. They really enjoy reading a random page on my site, usually some index page picked up by a crawler. They want me to insure a link to their site which is a brain dump site for CCIE Continue reading
Missing Manuals – io_uring worker pool
Chances are you might have heard of io_uring. It first appeared in Linux 5.1, back in 2019, and was advertised as the new API for asynchronous I/O. Its goal was to be an alternative to the deemed-to-be-broken-beyond-repair AIO, the “old” asynchronous I/O API.
Calling io_uring just an asynchronous I/O API doesn’t do it justice, though. Underneath the API calls, io_uring is a full-blown runtime for processing I/O requests. One that spawns threads, sets up work queues, and dispatches requests for processing. All this happens “in the background” so that the user space process doesn’t have to, but can, block while waiting for its I/O requests to complete.
A runtime that spawns threads and manages the worker pool for the developer makes life easier, but using it in a project begs the questions:
1. How many threads will be created for my workload by default?
2. How can I monitor and control the thread pool size?
I could not find the answers to these questions in either the Efficient I/O with io_uring article, or the Lord of the io_uring guide – two well-known pieces of available documentation.
And while a recent enough io_uring man page touches on the Continue reading
Lesson Learned: The Way Forward
I tried to wrap up my Lessons Learned presentation on a positive note: what are some of the things you can do to avoid all the traps and pitfalls I encountered in the almost four decades of working in networking industry:
- Get invited to architecture and design meetings when a new application project is starting.
- Always try to figure out what the underlying actual business needs are.
- Just because you can doesn’t mean that you should.
- Keep it as simple as possible, but no simpler.
- Work with your peers, and explain how networking works and why you’re facing certain limitations.
- Humans are not perfect – automate as much as it makes sense but no more.

Need to Keep Analytics Data in the EU? Cloudflare Zaraz Can Offer a Solution
A recent decision from the Austrian Data Protection Authority (the Datenschutzbehörde) has network engineers scratching their heads and EU companies that use Google Analytics scrambling. The Datenschutzbehörde found that an Austrian website’s use of Google Analytics violates the EU General Data Protection Regulation (GDPR) as interpreted by the “Schrems II” case because Google Analytics can involve sending full or truncated IP addresses to the United States.
While disabling such trackers might be one (extreme) solution, doing so would leave website operators blind to how users are engaging with their site. A better approach: find a way to use tools like Google Analytics, but do so with an approach that protects the privacy of personal information and keeps it in the EU, avoiding a data transfer altogether. Enter Cloudflare Zaraz.
But before we get into just how Cloudflare Zaraz can help, we need to explain a bit of the background for the Datenschutzbehörde’s ruling, and why it’s a big deal.
What are the privacy and data localization issues?
The GDPR is a comprehensive data privacy law that applies to EU residents’ personal data, regardless of where it is processed. The GDPR itself does not insist that personal data must Continue reading
