Ungayisebenzisa kanjani i-DNS esheshayo

Ukuqothula okuthunyelwe masisebenzise i-Linux, Ngithole kabusha eyodwa engingathanda ukuyijulisa. Imayelana nokuba khona kwegamabench, ithuluzi elivumela ukuhlola i-DNS ehlukile futhi elusizo olukhulu ukusheshisa ukuxhumana kwethu kwe-Intanethi.

 

Yini i-DNS

Iseva ye-DNS ifana nencwadi yocingo egcina izinombolo zocingo zabantu. Kulokhu, okugcinayo yinombolo ye-IP ehambelana namakheli e-Inthanethi esidlulisa kuwo amehlo.

Ngakho-ke, lapho ufaka i-www.google.com, iseva ye-DNS iyona eguqula lo mbhalo ube yinombolo ye-IP yomshini lapho kugcinwa khona ikhasi esifuna ukulibona. Sidinga amaseva e-DNS ngoba, ngokusobala, i-www.google.com kulula ukuyikhumbula kunenombolo ende.

Ngakolunye uhlangothi, kubalulekile ukuqonda ukuthi ayikho iseva ye-DNS eyodwa yawo wonke umuntu. Kukhona okubizwayo izimpande amaseva, okuyibo abaziyo ukuthi amaseva "asezingeni eliphezulu" akuphi ezingxenyeni ngasinye lapho umhlaba wahlukaniselwa khona futhi abagcina futhi "uhlu oluphelele" lwe-IPs. Kunezinsizakalo eziyi-13 kuphela emhlabeni. Bese kuba khona amaseva "asezingeni eliphezulu" agcina kuphela ingxenye yalolo hlu (ngokuvamile ehlotshaniswa nezici zendawo -.ar, .be, etc.- or generic-.com, .gov, etc.).

Kunamaseva amaningi, kukhona nezinhlelo ezizimele (ezinjengeGoogle nabahlinzeki be-Intanethi -ISP- bezwe ngalinye) ezinikeza izinsizakalo ze-DNS. Lawa amaseva we-DNS esiwasebenzisa kakhulu, ngoba uma singenayo inombolo efunwayo, badlulisela umbuzo kwenye iseva njalonjalo baze bathole impendulo.

Ukufingqa, ukukhetha eyodwa noma enye i-DNS kungathinta kakhulu ukusebenza koxhumano lwakho (kokubili ukulanda nokulayisha) njengoba kuthatha isikhathi eside ukuguqula i-URL ibe yinombolo ye-IP, kuzothatha isikhathi eside ukuthi ikhompyutha yethu ifinyelele lelo khasi. .

 

Ungayikhetha kanjani i-DNS esheshayo

i-namebench iyithuluzi le-multiplatform elizokusiza ukuthola amaseva we-DNS asheshayo futhi asondele kakhulu, kuya ngokuthi ikhompyutha ikuphi. Okwenzayo ukusebenzisa ukuhlolwa okuphelele kakhulu, kuthatha umlando wakho wewebhu, okukhishwayo kwe-tcpdump, namanye amasethi wedatha afanayo njengebhentshimakhi ukuze unikeze umbiko oningiliziwe kwi-DNS ngayinye futhi wenze isincomo sokuthi iyiphi okuzoba iseva engcono kakhulu nokuthi kungakanani ukuxhumeka kuzothuthuka ngaphezu kwe-DNS esetshenziswayo njengamanje.

[Isexwayiso] Qaphela, hhayi ukuthi njalo iseva eshesha kunazo zonke iphephe kakhulu noma yiyona evikela kakhulu ubumfihlo bakho. Enye indlela elinganisa ijubane, ukuphepha nobumfihlo evulekileNIC. [/ isexwayiso]

igamabench iyi-software yamahhala futhi ayiguquli uhlelo nganoma iyiphi indlela.

 

Ukufakwa

En Debian / Ubuntu kanye nokuphuma kokunye:

sudo apt-get ukufaka igama lebench

En Arch kanye nokuphuma kokunye:

i-yaourt -S igama lebench

Okunye, ungalanda ikhodi yomthombo bese uyihlanganisa.

Landa i-namebench

 

Sebenzisa

1. Lapho wenza umyalo igamabench, izovuleka.

2. Ngena ngemvume 127.0.0.1 en Amagama  bese ucindezela inkinobho Qala ibhentshimakhi, njengoba kuboniswe esithombeni esingezansi.

i-namebench isebenza

Ukushintsha i-DNS njengoba kunconywe yi-namebench imvamisa kungumsebenzi olula kakhulu, kepha njengoba kuyehluka kuye ngokusabalalisa okusebenzisayo, into elula ukudala ifayela le /etc/resolv.conf.head ngesandla, bese ufaka i-DNS ehambisanayo.

Ukuguqula ifayili le /etc/resolv.conf akusona isisombululo esihle kulezi zimo, ngoba lelo fayela liguqulwa yi-Network Manager nabanye abaphathi benethiwekhi. Ngalesi sizathu, ngincoma ukusebenzisa i- /etc/resolv.conf.head.

 

Imiphumela

Kwesinye isikhathi inkulumo ayinandaba nemiphumela. Lokhu kungaphambi nangemva kokumisa iseva yami ye-DNS, njengoba kunconyiwe yi-namebench.

Ngemuva

Kuyamangaza akunjalo? Noma kunjalo, kufanelekile ukucacisa ukuthi imiphumela incike ezintweni eziningi (ilunge kangakanani i-DNS yakho yamanje, indawo okuyo, ijubane le-Intanethi elinikezwe yi-ISP yakho, njll.).

      Bengingazi ngama-opendns. Kubuhlungu kanjani.
      Ngabe ukhona ophakamisa noma iyiphi i-DNS ehlonipha ubumfihlo nenkululeko?
      akunakwenzeka ngeke kube khona

        Ngiyaphendula ngabelane

        I-OpenNIC
        I-OpenNIC yiphrojekthi yezimpande ze-DNS zamahhala nokubhaliswa kwamagama wesizinda nokunye ukuphathwa kwe-ICANN (Internet Corporation Yamagama Nenombolo Ezabelwe). Le phrojekthi isekelwa umphakathi wabasebenzisi osebenzisana ekufezeni inethiwekhi yonke yamaseva we-DNS mahhala futhi asetshenzisiwe, ngaphandle kokusinikeza izinsizakalo zokuxazulula igama lesizinda eliphethwe yi-ICANN, futhi lisinika ukufinyelela esikhaleni esiqhutshwa yi-OpenNIC futhi leyo ingaphandle kwemithetho yalesi sigungu engaphansi kwemithetho yoMbuso waseCalifornia.

        Ukufunwa kwale nkululeko kuholele emndenini wamaseva, phakathi kokunye, angagcini umbhalo wemibuzo eyenziwe abasebenzisi (noma asuswe ngemuva kwamahora angama-24) ngaphezu kokusinikeza insizakalo kuleyo "ngxenye i-Intanethi "engalawulwa yi-ICANN.

        1.    eliotime3000 kusho

          Umbuzo: Uma ngisebenzisa i-OpenNIC, ingabe amasayithi afana ne-Hulu, i-Vevo noma iyiphi enye iwebhusayithi evinjelwe endaweni yase-US azotholakala nalolo shintsho lwe-DNS noma azoqhubeka nalowo mkhawulo wendawo?

      2.    I-Tor kusho

        I-OpenNIC ngaphezu kwakho konke okwenzelwe ukuphathwa kwesizinda okungaziwa yi-ICANN, ngakolunye uhlangothi nge-OpenDNS inokuphepha kokubethela nge-DNSCript futhi ithuthukisa ukuxhumana kwakho njengoba benza ukulondolozwa kwesikhashana kumaseva abo, izinsiza ezinjenge-facebook, i-gmail, ne-twitter umthwalo oshesha kakhulu.

    i-opendns ingumxhumanisi omkhulu we-google kune-dns uqobo, ngaphezu kokuqoqa imininingwane esiyisebenzisa kuwebhu njengokungena ngemvume, amaphasiwedi, amakhasi ... uma nje kudingeka (https://www.opendns.com/privacy/) akunconyiwe!.

    1.    masisebenzise i-linux kusho

      Ungishiya ngamakhaza Ngisanda kuqeda ukufunda imigomo yokusetshenziswa evulekile:

      Singasebenzisa amakhukhi wenkampani yangaphandle njengengxenye yemisebenzi yokumaketha futhi esiyenza ne-Google kanye / noma abanye abathengisi abavela eceleni, ukukusiza ukukunikeza ngeminikelo yokuphromotha efanelekile njengoba usebenzisa i-Intanethi. Njengengxenye yale misebenzi yokumaketha kabusha, lawa makhukhi avela eceleni angarekhoda ukuvakasha kwakho kumawebhusayithi ethu namawebhusayithi avakashelwe ngaphambi kokusebenzisa amawebhusayithi ethu. Amakhukhi anjalo angabe esetshenziselwa ukuletha izikhangiso kuwe kwamanye amawebhusayithi. Ungakhetha ukukhululwa ekusebenziseni amakhukhi wokumaketha kabusha we-Google ekhasini lobumfihlo lokukhangisa le-Google. Ngenye indlela, ungakhetha ukuphuma ekumakethweni kabusha kunethiwekhi ye-Google nakwamanye amanethiwekhi afanayo ekhasini lokuphuma le-Network Advertising Initiative.

        Lokho, kungaba nje okuthakazelisayo i-athikili mayelana ne-tor ebuyekeziwe,
        okungukuthi, okungcono noma abakhetha kona:
        - Landa futhi usebenzise i- «Tor Browser Bundle», ekhasini le-Tor
        - Faka kusuka ekuphumuleni: i-tor, i-privoxy ne-vidalia, inkinga ukuthi singayilungisa ngokufana ne-Tor Browser Bundle.

        Ukulawula,

        Yiqiniso. Ukushintsha i-DNS akuguquli isivinini sokulanda sefayela elingu-200MB, ngokwesibonelo. Kodwa-ke, njengoba ukuphequlula i-inthanethi kuqukethe ukuxhumana okuningi (ikhasi ngalinye odlulisa amehlo kulo, futhi nakuzo zonke ikhasi ngalinye, ikhodi ngayinye ye-JS, i-CSS ngayinye, okungukuthi, isicelo ngasinye esenziwa yilelo khasi) lokho okuncane okuthuthukisa isivinini lapho kuguqulwa ama-URL ku Ama-IPs agcina ebalulekile.
        Isiphetho, ngeke ulande amafayela ngokushesha kepha uzobona ukuthuthuka kokuzulazula. Izinga lokuthuthuka lincike ezintweni eziningi.

    Akukho ezinqolobaneni zeManjaro, landa imithombo futhi awudingi ukuhlanganisa noma yini, iku-python, elula ./namebench iyasebenza, ukusebenzisa isikhombimsebenzisi sokuqhafaza kuyadingeka ukuthi ufake i-python-tk, kepha kuyasebenza nakwi-console. Kwakukuhle ukuthola nge-OpenDNS, nami nganginephutha kakhulu, imikhonzo.

  10.   I-Tor kusho

    Kulabo abafuna isivinini ekuxhumaneni kwabo, ukusetha iseva ye-DNS bekungeke kusebenze ngoba iPC yakho izokwandisa ukusetshenziswa kwezinsizakusebenza kanye ne-bandwidth ezokwehlisa ukusebenza kwayo esikhundleni sokwenza ngcono.

    A -1 yokungaguquguquki kokuthunyelwe, wazi ukuthi okushoyo kuyiphutha ... lokho noma ngabe ufuna ukudukisa.

    1.    i-milo kusho

      Angiboni ukuthi okuthunyelwe kufanele kubuzwe imibuzo. Okukuveza ngokusobala ukuthi ukuthuthukisa ukukhetha kwe-DNS kungathuthukisa isivinini sokuxhuma. Akukho okushiwo ngokuthuthukisa isivinini sokulanda. Izici zobumfihlo azikhulunywa kokuthunyelwe ngoba kungenye inhloso. Ukuphawula kube nomthelela eminye imibuzo enothisa okuthunyelwe. Ngokubona kwami, umnikelo weposi (kanye namazwana abekiwe) muhle kakhulu, kulwazi olunikezayo nenzuzo etholwa ukufundwa kwayo kubabukeli abahlukahlukene. Ngiyacacisa: (Angazi ukuthi umbhali noma buphi ubuhlobo naye, kungokokuqala ngqa ukuthi ngingene kule sayithi futhi ngathola ukusesha okujwayelekile, kumane kubonakala kimi ukuthi inhloso yayo iyiqiniso futhi iyasekela futhi akufanele kubuzwa kepha kukhushulwe futhi kwaziswa).
