Category 6 cables -- and to a lesser extent, Category 6a cables -- are widely available from a variety of vendors, including variety stores, office supply stores, consumer electronics stores, and online shops. While a great many people are content to run wireless networks in their homes, the fact is that if you need…
When I first started digging into the bowels of the Internet, I was fascinated by how many of its protocols—like HTTP and SMTP, for example—were entirely text based.
News and announcements from Namebase.
tl;dr: I successfully got the Intel I340-T4 4x Gigabit NIC working on the Raspberry Pi Compute Module 4, and combining all the interfaces (including the internal Pi interface), I could get up to 3.06 Gbps maximum sustained throughput. Update: I was able to boost things a bit to get 4.15 Gbps! Check out my video here…

This post is the perfect starting point for learning to build your own LTE network. View this lession as a guided introduction – including the installation, configuration, and best practices that will ease your learning.
Have you ever been connecting to a new wireless network and seen the following pop-up balloon?
BGP is the glue between all of the thousands of border routers that make up the internet (you can find this post (battleships) and this post (EvE) as a crash course on how BGP works).
Why the threat actor rushed deployment.
How would the current internet function when you're on a native IPv6 host without any IPv4 instead of using any of the IPv4 workarounds? Find out with a few firewall rules!
SMS text messages were already the weakest link securing just about anything online, mainly because there are tens of thousands of employees at mobile stores who can be tricked or bribed into swapping control over a mobile phone number to someone else. Now we’re learning about an entire ecosystem of companies that…
Twitter tried to reduce load times for external links, but made things slower instead. It mistakenly normalizes domains to a point where they’re no longer useful.
Just over a year ago, we founded Tailscale with a common sense of nostalgia for the “good old days” of LANs. In our collective opinion (then and now) networking and cloud infrastructure has become too complicated. Attempts to increase team connectivity and migrate towards remote work results in a corresponding burden…

Unlike TCP, UDP doesn't provide any delivery or ordering guarantees. Put into practice, just how bad, or good, is UDP?
From time to time Microsoft decides to block or even silently drop emails that are sent by my selfhosted email server. It’s always a pain and takes a lot of effort to deal with it. This time I decided to…Read more ›
The algorithm in this post needs “double buckets” to be reliable. Otherwise, the two sides can split on bucket boundaries and fail to converge. If the first bucket fails, compute an additional bucket step for convergence. My algorithm trades slow startup for less infrastructure.
Implementing Precision Time Protocol (PTP) at Meta allows us to synchronize the systems that drive our products and services down to nanosecond precision. PTP’s predecessor, Network Time Protocol (…

For the past eight months, Trail of Bits has worked with the Python Cryptographic Authority to build cryptography-x509-verification, a brand-new, pure-Rust implementation of the X.509 path validation algorithm that TLS and other encryption and authentication protocols are built on. Our implementation is fast…
