Iyiphi i-IPv6 source ekhethwa isicelo se-VPN, futhi kungani kubalulekile

Wengeza ikheli le-VPN futhi wawulindele ukuthi isicelo sisebenzise lona, kodwa iseva yayisabhala i-prefix endala. Akukho okwahluleka emhubheni; i-host yenza ukukhetha ikheli lomthombo ngaphambi kokuthi ibheke indlela obuyigqolozele. Ukukhethwa komthombo we-IPv6 kuwumncintiswano wohlobo oluhlukile futhi ohleliwe phakathi kwamakheli angabangeneleli e-host, futhi i-prefix ehambisana kakhulu ende ingumthetho owodwa eduze nokuphela kwalowo mncintiswano. Ukuthola umphumela owufunayo kudinga ukwazi ukuthi muphi umthetho osewunqobile. Imithetho ngokwayo iyisicefe futhi inemba, futhi yiso leso sizathu sokuyifunda ngokulandelana.

Ukusesha okubili, hhayi okukodwa

Ukukhethwa kwendawo okuya kuyo kunquma igxathu elilandelayo ne-interface yokuphuma. Bese kuthi ukukhethwa komthombo kunqume ukuthi yiliphi ikheli le-host elizovela esihlokweni, futhi le mibuzo emibili iphendulwa izindlela ezihlukene nakuba zombili zisebenzisa ama-prefix. I-host enekheli lomzimba, ikheli lesikhashana nekheli le-VPN inabangeneleli abathathu kunoma iyiphi indawo, futhi indlela eya ku-VPN ayiphakamisi owesithathu ngokuzenzakalela.

Yingakho indlela efanele nomthombo ongafanele kuhlala ndawonye kalula kangaka, nokuthi kungani isicelo esifanayo singaziphatha ngenye indlela sisuka kusiphequluli nasesixhumweni esiphoqiwe. Thatha ukusesha okubili njengokuhlukene kuze kube unobufakazi obuzixhumanisayo.

Funda imithetho njengomncintiswano ohleliwe

I-RFC 6724 ibala imithetho ngokulandelana, futhi ngamunye uphula kuphela ukulingana okushiwo yimithetho eyandulelayo. Ukuthandwa kwe-interface yokuphuma nokufana kwelebula kuvela kakhulu ngaphambi kokuqhathaniswa kwama-prefix, ngakho ikheli kuyi-interface esetshenziswa indlela selivele lathola inzuzo okungeke kuyisuse ukufana kwe-prefix okungcono. Ukuphelelwa yisikhathi nobubanzi nakho kuyahlanganyela, futhi yingakho ikheli elidala ngezinye izikhathi liyeka ukukhethwa ngaphandle kokuthi othile ashintshe inqubomgomo.

Ukufunda okungokoqobo ukuthi awukwazi ukucabanga ngomnqobi ngendawo kuphela. Bhala abangeneleli, hamba ngemiyalelo yesigaba, futhi ubheke lapho isinqumo sithathwe khona ngempela, ngemva kokuhamba ngemithetho ngokulandelana.

Qaphela futhi ukuthi lena ingxenye yomthombo yenkinga. Ukuhlanganisa iziqhathaniso ezimbili ze-prefix kukhiqiza izincazelo ezizwakala ziqinile kodwa ezibikezela ikheli elingalungile. Shawosho ukuthi yisiphi isiqhathaniso osiqondile noma nini uma usebenzisa igama i-prefix ethikithini.

Ukuxhumana kohlelo kushintsha umbuzo

Uhlelo lungacela ikheli lomthombo elithile, futhi ukukhetha okucacile okuvumelekile kuhambisa umbuzo kusuka ku-“yiliphi ikheli i-host engalithanda” kuya ku-“ingabe lelo kheli lingafinyelela indawo bese libuya”. Amathuluzi axhumana nomthombo, noma acela idatha eyengeziwe mayelana nekheli elikhethiwe, akubeka lokhu ngqo, futhi yiwo indlela eshesha kakhulu yokuqinisekisa ukuthi ukuxhumana kwasebenzisa liphi ikheli ngempela. Lokho kuhlolwa kudlula ukufunda ithebula lezindlela okwesithathu, ngoba kubika lokho okwanqunywa i-kernel hhayi lokho okulungise. Kuphinda ngemva koshintsho futhi uqhathanise izimpendulo ezimbili.

Lokhu kwenza ukuxhumana komthombo kube yithuluzi lokuxilonga kanye nesixazululo sesikhashana: xhuma ikheli le-VPN bese ubheka ukuthi isicelo siyaphumelela yini. Uma siphumelela, indlela ilungile futhi ukukhetha kwakuyinkinga. Uma sihluleka, indlela yokubuya noma inqubomgomo yohlangothi olude kwakuyinkinga kusukela ekuqaleni.

Qinisekisa ukuthi uhlangothi olude lwamukela lowo mthombo

Noma i-host ikhetha ini, kufanele ihambisane nobubanzi obuvikelwe be-VPN kanye nendlela yokubuya nemithetho yokufinyelela yasemkhawulweni okude. Umthombo ongaphandle kwabakhethi ungathathelwa emhubheni bese ulahlwa emkhawulweni okude, okubonakala njengokwehluleka kohlangothi olulodwa futhi kugxekwa ukuhlelwa kwezindlela. Qhathanisa umthombo wangaphakathi okhethiwe nobubanzi bokuvikela ngaphambi kokuthinta izilungiselelo zokubethela, ngoba ukushintsha imodi akukhethi phakathi kwamakheli angabangeneleli.

Gcina ikheli lephendulo langaphandle lihlukile ekucabangeni kwakho. Libonisa ukuthuthwa phakathi kwabahlanganyeli be-VPN futhi akulona umthombo wephakethe lohlelo ngaphakathi.

Nquma ngokubonwa okune

Bhala indawo esetshenzisiwe, imithombo yasendaweni efanele, umthombo okhethwe ngempela kanye nendlela yokuphuma esebenzayo. Imigqa emine yanele ukuchaza cishe zonke izimo, futhi ingaqhathaniswa phakathi kwe-host esebenzayo nengasebenzi ngaphandle kokuphinda kuxoxwe ngethiyori. Ukuze uthole isinyathelo sokukhetha sebenzisa umbono osekelwe wohlelo lokusebenza ngokwalo esikhundleni segama elivela kumgangatho, ngoba ukusetshenziswa kwengeza izintandokazi zasendaweni zazo.

Uma impendulo isakumangaza, ukuhleleka kwenza into okungeyona eyomfanekiso wakho wengqondo, futhi isisombululo ukushintsha okokufaka hhayi ukuphikisana ne-algorithm. Bhala ukubonwa okune ethikithini futhi umfundi olandelayo angakwazi ukuphinda isiphetho sakho.
