/* Funny. This algorithm seems to be very broken. These formulae increase RTO, when it should be decreased, increase too slowly, when it should be increased quickly, decrease too quickly etc. I guess in BSD RTO takes ONE value, so that it is absolutely does not matter how to _calculate_ it. Seems, it was trap that VJ failed to avoid. 8) */

Soplan vientos de cambio en las tendencias de desarrollo de sistemas informáticos. Queda una semana para el apocalipsis #Docker y quienes tengan solo #IPv4 con #cgnat se van a divertir tratando de hacer pulls. Recordando que a partir del 1 de marzo de 2025 solo se podrán hacer 10 pulls por hora por IPv4. Con cuenta registrada, solo 40 por hora. No queda claro si esas cuentas pueden ser desde la misma IPv4, pero ya estará obligando a crear configuración adicional y complicar (todavía más) todo.

P*rseensuti kun elämänsä voi tehdä itselleen vaikeaksi… Hakkaan hyvän aikaa päätäni seinään miettien, miksei #virtuaalikone suostu yhdistämään #NAS'sin #NFS-jakoa, vaikka asetusten pitäisi olla kunnossa ja NASsia pystyy #ping'aamaankin. Myös #SSH:lla pääsee kaikkiin koneisiin paitsi NASsiin.

No äh, minähän asetin juuri eilen virtuaalikoneiden #IPv4-osoitteen viimeisen oktetin alkamaan 130:stä, ja NASsilla torpataan osoitteet, joissa se on ≥ 128! #atkjuttuja #miehenelämää

🌐 Types of IP Addresses Every Cybersecurity Learner Should Know 🔐

As a cybersecurity learner, understanding IP addresses is crucial for securing networks, identifying potential threats, and properly managing devices. IP addresses serve as unique identifiers for devices on a network and help to route data to the correct destination.

#TIL: You can use a /31 network for a point-to-point connection to avoid wasting the, in this case, unneeded network and broadcast addresses.

And, as it turned out, both #MikroTik and #AVM support this. As of RouterOS 7.17, the configuration is a little unexpected, however, I read that this will change in RouterOS 7.18. 🎉

I am trying to configure through alias instead of single CIDR notations, as soon as I make the changes, clients from the outside can't connect, even after restarting the openvpn server. But testing with a machine I have here through a mobile provider hotspot the new openvpn settings work. *scratches head*

IPv4 and IPv6: Evolution, Key Differences, and the Engineers Behind the Protocols

The Internet Protocol (IP) serves as the foundational communication system for the internet, dictating how data packets are addressed and transmitted across networks. The two primary versions in use today are IPv4 and IPv6, each with distinct characteristics, histories, and contributions from various engineers.

Also I never want to hear any grief about hanging onto my tiny handful of IPv4 addresses because those mofos have literally hundreds of thousands in just a single one of those blocks, probably several million altogether. Add up those CIDR ranges if you want. Facebook can rot in hell.

If you're wondering where all the IPv4 addresses went, I found them.

From IPv4 to IPv6: Is Your Network Ready for the Future? 🌐✨

In today’s world, we’re all just a tap away from connecting with anyone, anywhere. Sending a message feels like magic—it’s instant, seamless, and happens in the blink of an eye. But have you ever stopped to think about how it actually works? 🤔

The secret? The internet’s backbone: IP addresses. Every device online has one, just like your home has a mailing address. But here’s the twist: the internet is evolving, and so are these addresses. Enter IPv4 and IPv6—the two versions powering our digital world.

IPv4 has been the OG for decades, but with billions of devices now online, we’re running out of addresses. That’s where IPv6 steps in, offering a massive upgrade with way more addresses and better performance.

So, is your network ready for the switch? Let’s break it down and future-proof your connection! 🚀

Использование команд Telnet в Linux/Unix

Telnet (telecommunications network) — это сетевой протокол (работающий по TCP-соединению), предназначенный для ручного управления удаленными машинами с помощью команд консольного терминала. С помощью Telnet команды вводятся на локальной машине, а выполняются на удаленной. То есть пользователь сперва вводит IP-адрес и порт (по умолчанию 23) удаленного сервера, после чего выполняет команды на нем. Несмотря на то, что в наши дни чаще всего используется SSH, Telnet до сих пор остается популярным инструментом для управления удаленными хостами. В этом руководстве будет рассмотрено базовое использование команд Telnet в операционных системах на базе Linux. Все показанные примеры запускались на облачном сервере Timeweb Cloud под управлением операционной системы Ubuntu 22.04.

Hey #homelab users!

You probably already know me by my free @BoxyBSD project and I often got asked about IPv4 addresses. Currebtly, I tinker with a new but also honestly not free service. The idea is creating a static IP service for homelab users. I'm aware that there're already some around, so what could be some benefits here?

- Static single #IPv4 & #IPv6 /48 (so you can subnet your homelab to several /64 without breaking #slacc)
- Bigger subnets (IPv4: /29, /28, /27 | IPv6: /32)
- Full RIPE personalization (inc. abuse & Co)
- #OpenVPN, #Wireguard, #GRE Support
- Auto configure (e.g., you load the wireguard config on any client and the addresses Arena immediately bound to that interface)
- Split usage / multiple tunnels: Use different IPs from your subnets at different locations
- Integration into #BoxyBSD
- Location in Germany or Netherlands (selectable)
- Hosted on redundant #FreeBSD nodes

Pricing:
- The starter package probably around 10€/month (not more) + 15€ setup including 2T traffic
- Pricing for addiriinal/larger subnets not yet sure, probably higher setup fees to avoid hoppers and spamers to keep the addresses clean
- Optional traffic packages (when exceeding speed Limit of 10Mbit which should still be ok for most homelabs)

World this be interesting? Im aware that many ones already do this by VPS themselves, so this might just be a bit easier and optionally offering whole networks including RIPE personalizations.
