As long as we get to make our own network security tools, why not make them look cute? Netgotchi may not be much more than an ESP8266 running network scans and …read more Continue reading A Cute Sentry Scans Your Net for Scullduggery
Around here, printers have a life expectancy of about two years if we are lucky. But [techtipsy] has a family member who has milked a long life from an old …read more Continue reading Raspberry Pi Saves Printer from Junk Pile
Many hackers have familiar sayings in their heads, such as “If it ain’t broke, don’t fix it” and KISS (Keep it simple, stupid). Those of us who have been in …read more Continue reading Embrace IPv6 before its too late?
You want to pass TCP traffic from one computer to another, but there’s a doggone firewall in the way. Can they both see a shared file? Turns out, that’s all …read more Continue reading Tunneling TCP By File Server
We’re all used to wireless networking, but if there’s one thing the ubiquitous WiFi on 2.4 or 5 GHz lacks, it’s range. Inside buildings, it will be stopped in its …read more Continue reading So What’s All This HaLow Long-Range WiFi About Then?
A network-attached storage (NAS) device is a frequent peripheral in home and office networks alike, yet so often these devices come pre-installed with a proprietary OS which does not lend …read more Continue reading Squeeze Another Drive into a Full-Up NAS
A modern normal network card will have onboard an Ethernet controller which, of course, is a pre-programmed microcontroller. Not only does it do the things required to keep a computer …read more Continue reading Homebrew Network Card with No CPU
When Ethernet was originally envisioned, it would use a common, shared medium (the ‘Ether’ part), with transmitting and collision resolution handled by the carrier sense multiple access with collision detection …read more Continue reading How DEC’s LANBridge 100 Gave Ethernet a Fighting Chance
Do you really need that cloud hosting package? If you’re just running a website — no matter whether large or very large — you probably don’t and should settle for …read more Continue reading On Cloud Computing And Learning to Say No
To the average microcontroller, Ethernet networks are quite a step up from the basic I2C, SPI and UART interfaces, requiring either a built-in Ethernet MAC or SPI-based MAC, with tedious …read more Continue reading SatCat5: UART, SPI and I2C via Ethernet With FPGA-Based Design
