Kutha kwa mwezi woyamba ndi koyambirira kwa mwezi wachiwiri wa chilimwe 2019 kunakhala kovuta ndipo kudadziwika ndi madontho angapo akuluakulu pazantchito zapadziko lonse lapansi za IT. Zina mwazodziwika: zochitika ziwiri zazikuluzikulu za CloudFlare (zoyamba - zokhala ndi manja okhotakhota komanso malingaliro osasamala pa BGP mbali ya ma ISPs ochokera ku USA; chachiwiri - ndi kutumizidwa molakwika kwa CF okha, zomwe zidakhudza aliyense wogwiritsa ntchito CF. , ndipo awa ndi mautumiki ambiri odziwika) ndi ntchito yosakhazikika ya Facebook CDN zomangamanga (zakhudza zinthu zonse za FB, kuphatikizapo Instagram ndi WhatsApp). Tidayeneranso kugwa pansi pa kugawa, ngakhale kuti kutha kwathu sikunali kowonekera kwambiri poyerekeza ndi dziko lapansi. Winawake wayamba kale kukoka ma helikoputala akuda ndi ziwembu za "wachifumu", kotero tikutulutsa chiwembu chapagulu cha zomwe zidachitika.

Mavuto ndi zothandizira anayamba kulembedwa, mofanana ndi kuwonongeka kwa mgwirizano wamkati wamkati. Popeza sanayang'ane zonse, adayamba kulakwitsa ntchito ya njira yakunja kupita ku DataLine, popeza zidawonekeratu kuti vuto linali ndi intaneti yapaintaneti (NAT), mpaka kuyika gawo la BGP ku DataLine.
03.07.2019, 16: 35
Zinadziwika kuti zida zomasulira maadiresi a netiweki ndi mwayi wopezeka pa intaneti yapamalopo kupita pa intaneti (NAT) zidalephera. Kuyesera kuyambiranso zida sikunatsogolere ku chilichonse, kufunafuna njira zina zopangira kulumikizana kunayamba musanalandire yankho kuchokera ku chithandizo chaukadaulo, chifukwa chodziwa, izi sizikanathandiza.
Vutoli lidakulitsidwa chifukwa chakuti zida izi zidathetsanso kulumikizana kwa kasitomala wa VPN ogwira ntchito, ndipo ntchito yobwezeretsa kutali idakhala yovuta kwambiri kuchita.
03.07.2019, 16: 40
Tidayesetsa kutsitsimutsa chiwembu chomwe chinalipo kale cha NAT chomwe chidagwira ntchito bwino m'mbuyomu. Koma zinaonekeratu kuti kukonzanso ma netiweki angapo kunapangitsa kuti chiwembuchi chikhale chosagwira ntchito, popeza kubwezeretsedwa kwake kungathe, chabwino, kusagwira ntchito, kapena, poyipa kwambiri, kuswa zomwe zinali zikugwira ntchito kale.
Tinayamba kugwira ntchito zingapo malingaliro kusamutsa magalimoto ku seti ya ma routers atsopano omwe akutumikira msana, koma adawoneka kuti sangagwire ntchito chifukwa cha zosiyana za kugawa kwa mayendedwe pa intaneti.

Panthawi imodzimodziyo, vuto linadziwika mu njira yothetsera mayina pa ma seva a mayina, zomwe zinayambitsa zolakwika pakuthetsa mapeto muzogwiritsira ntchito, ndipo anayamba kudzaza mwamsanga mafayilo a makamu ndi zolemba za mautumiki ovuta.
03.07.2019, 17: 27
Ntchito zochepa za Habr zabwezeretsedwa.
03.07.2019, 17: 43
Koma pamapeto pake, njira yotetezeka kwambiri idapezeka yokonzekera magalimoto kudzera m'modzi mwa ma routers amalire, omwe adayikidwa mwachangu. Kulumikizana kwa intaneti kwabwezeretsedwa.
M'mphindi zingapo zotsatira, zidziwitso zambiri zidabwera kuchokera ku machitidwe owunikira okhudza kubwezeretsedwa kwa ntchito za oyang'anira, koma ntchito zina zidakhala zosatheka chifukwa njira yosinthira mayina pamaseva a mayina (dns) idasweka.
03.07.2019, 17: 52
NS idayambitsidwanso ndipo posungira idachotsedwa. Kuthetsa kwabwezeretsedwa.
03.07.2019, 17: 55
Ntchito zonse zidayamba kugwira ntchito kupatula MK, Freelansim ndi Toaster.
03.07.2019, 18: 02
MK ndi Freelansim anayamba kugwira ntchito.
03.07.2019, 18: 07
Bweretsani gawo losalakwa la BGP ndi DataLine.
03.07.2019, 18: 25
Iwo anayamba kulemba mavuto ndi zothandizira, zomwe zinali chifukwa cha kusintha kwa adiresi yakunja ya dziwe la NAT ndi kusowa kwake mu acl ya mautumiki angapo, omwe adakonzedwa mwamsanga. The Toaster inayamba kugwira ntchito nthawi yomweyo.
03.07.2019, 20: 30
Tidawona zolakwika zokhudzana ndi Telegraph bots. Zinapezeka kuti aiwala kulembetsa adilesi yakunja mu ma acl angapo (maseva oyimira), omwe adakonzedwa mwachangu.
anapezazo
- Zida, zomwe kale zidafesa kukayikira za kuyenerera kwake, zidalephera. Panali mapulani oti athetse ntchitoyi, chifukwa idasokoneza chitukuko cha intaneti ndipo inali ndi mavuto ogwirizana, koma nthawi yomweyo imagwira ntchito yovuta, chifukwa chake kusinthika kulikonse kunali kovuta mwaukadaulo popanda kusokoneza ntchito. Tsopano mutha kupitilira.
- Nkhani ya DNS ikhoza kupewedwa powasunthira pafupi ndi netiweki ya msana watsopano kunja kwa netiweki ya NAT ndikukhalabe ndi kulumikizana kwathunthu ku netiweki imvi popanda kumasulira (yomwe inali dongosolo lisanachitike).
- Simuyenera kugwiritsa ntchito mayina a madambwe posonkhanitsa magulu a RDBMS, chifukwa kusavuta kusintha ma adilesi a IP sikofunikira kwenikweni, chifukwa zosokoneza zotere zimafunikirabe kumanganso gululo. Chisankhochi chinakhazikitsidwa ndi zifukwa za mbiri yakale ndipo, choyamba, ndi kuwonekera kwa mapeto ndi dzina mu masanjidwe a RDBMS. Ambiri, tingachipeze powerenga msampha.
- M'malo mwake, zolimbitsa thupi zofananira ndi "kudziyimira pawokha kwa Runet" zachitika; pali china chake choti muganizire polimbikitsa kuthekera kopulumuka.
