  1. Почему порты стали «дверями» в сервер, и кто решил, что SSH будет 22

    В 1995 году Тату Илонен написал письмо длиной с пост на Хабре и бесплатно получил номер ssh -p 22 user@host, который теперь знает каждый сисадмин. Но до этого порты были однонаправленными, чётные номера считались ненужными, а половина слотов вообще пустовала. О том, как порты стали «дверями» в сервер и что останется от них через десять лет, рассказал в статье. Читать

  6. Сети База для начинающих

    Микросервисы запускаются, контейнеры оркестрируются, а сеть… ну, она как-то сама работает. Негласное правило многих начинающих разработчиков и админов: работает — не трогай. Но ровно до тех пор, пока в продакшене не отвалится резолв DNS или база данных не станет отдавать странные таймауты. В этот момент сеть превращается в настоящую головную боль.

  16. Страшно, когда не видно: аудит сетевых устройств

    Представьте, что вы не знаете, какие устройства подключены к вашей сети, как они настроены и что там происходит. Страшно? Ещё бы! Многие компании как раз так и живут — не уделяют внимания аудиту сетевого оборудования. А зря. Без такой инвентаризации невозможно ни нормально управлять ИТ-инфраструктурой, ни защититься от угроз. Мы наблюдаем в инфраструктуре клиентов это так часто, что поняли – нужно выдать базу. Мы – это руководитель практики развития MaxPatrol Carbon Константин Маньяков и эксперт центра безопасности (PT ESC) Данил Зарипов, и в этой статье мы будем разбираться в ключевых аспектах аудита сетевых устройств, его роли в построении эффективного управления активами и повышении уровня защищенности ИТ-инфраструктуры.

  17. Eine DSL-#Fritzbox kann nur mit einem externen optischen Terminator (#ONT) verbunden werden, wenn sie dafür den ersten LAN-Port und *kein* Gästenetz über LAN4 verwendet.

    Wenn man das Gästenetz-Feature über viele Jahre verwendet hat, ist eine solche Umstellung aufwändig und fehleranfällig. Um ein #NAT-Gateway kommt man m.E. nicht herum.

    Ich werde das wohl über den USV-unterstützten Mini-#Homeserver realisieren und dort per #iptables das Nicht-Gästenetz per NAT in das Gästenetz überführen.

  18. Ищем альтернативу Ngrok в России

    Мне часто нужно открыть доступ к локальному стенду, вебхуки там и так далее, и раньше я всегда использовал Ngrok. По последнее время пользоваться им становится сложнее, оплатить подписку уже нельзя, а бесплатные функции всё время урезают. По этому решил найти какие есть альтернативы, желательно в России.

  19. Something to consider about all of the efforts to sustain #IPv4 so far beyond its original shelf life. #NAT and #IPv6 were thought out at roughly the same time. NAT was a tactical move to stave off IPv4 exhaustion (at the cost of limiting the peer-to-peer nature of the Internet) and IPv6 was the strategic answer for scalable growth. The obsession human beings have to find any excuse to avoid change was highly underestimated. IPv6 took 22 years to become an Internet Standard and NAT became so entrenched that peer-to-peer networking became mostly unnecessary as long as we could continue to laugh at cat memes on our favourite platforms.

    This brings us to #platforms. It’s getting harder to host anything ourselves anymore without paying a (usually foreign) IaaS/SaaS platform to do it for us. We now live in an age where data sovereignty and privacy are at the forefront of our thinking and maybe, just maybe, we want other options.

    Is our obsession with IPv4 tying us unhealthily to platforms and sacrificing our freedoms?

  20. Just over a month and I've tamed all the #trunks (with abundant snake heads at the end), made sure 1500+ #blighters are yeeted (with more trying every day) got inter #PBX #trunk working between on-premises and cloud #FreePBX - just waiting for porting of first analogue number to check this (and CLID presentation) works and then main office one can follow.

    Took many late evenings, a lot of research of everything from old #BritishTelecom training manuals to some from Universities in India and the Indian telecom companies, and I've learned a lot more about #SIP even since 2008 when I built the first #VOIP #PBX used at work.

    Thankfully #routers seem to handle #SIP over #NAT a lot better than they used to (even got an extension it working over #LTE with #Linphone)
