Indlela yokuhlola i-kill switch ye-VPN ngaphandle kwama-akhawunti angempela
Yenza ukuhlolwa kwe-kill switch ngekhasi lokukhohlisa nephrofayili eyisipele: hlanganisa zonke izinhlobo zokuphazamiseka, funda amakhodi okuphuma e-curl futhi uhlukanise ukuvinjwa kwangempela nokuhluleka kwe-DNS.
Awudingi i-akhawunti yangempela ukuze uthole ukuthi i-kill switch iyabamba yini; i-akhawunti uqobo iyona evikelwa yilezi zivivinyo engozini. Ukuhlola kwakha iwindi elifushane lapho ithrafikhi ingase iphume noma ingaphumi ngaphandle komhubhe, ngakho umthwalo kufanele ube yinto ongakwazi ukuyilahla. Manje ngikwenza lokhu ngekhasi lokukhohlisa nephrofayili yesipele yesiphequluli, futhi impendulo icaca kakhulu kunendlela yesiphequluli ne-webmail engangiyisebenzisa ngaphambili. Ngezansi ngilandela ukulandelana okufanayo okuvezwa iklayenti: isilungiselelo, indawo, ukudlula, bese kuba ubufakazi.
Isivivinyo siphendula umbuzo owodwa omncane: phakathi nalokhu kudlula, ingabe lolu hlelo lokusebenza lungafinyelela inethiwekhi ngaphandle komhubhe? akusho lutho mayelana nokuthi ingabe inqubomgomo esele inengqondo yini. Gcina ububanzi buncane kangako futhi umphumela ufanele ukubhalwa phansi.
Thola iswishi nobubanzi baso kuklayenti
Vula iklayenti futhi uthole isilungiselelo sokuvimba ngaphambi kokushintsha noma yisiphi isimo senethiwekhi. Abakhiqizi bayibiza ngezindlela ezahlukene: i-kill switch, imodi yokukhiya, ukukhiya kwenethiwekhi, ukuvimba ithrafikhi ngaphandle komhubhe. Ilebula isho okuncane kunezinketho ezingaphakathi kwayo. Okubalulekile ukuthi ukuvinjwa kusebenza ngaso sonke isikhathi noma kuphela lapho uhlelo lunquma ukuthi umhubhe usanda kwehluleka, nokuthi kuhlanganisa zonke izinhlelo noma uhlu olukhethiwe.
Bese ufake ohlwini lokudlula iklayenti lakho elikwazi ngempela ukukwenza. Ukunqamuka okuqalwe umsebenzisi, ukuphuma kuhlelo nokulahlekelwa ukuxhumana neseva kuyizindlela ezintathu ezahlukene zekhodi kumaklayenti amaningi, futhi azihlanganyeli inqubomgomo eyodwa yokuvimba. Ezinye zidedela ukuvinjwa lapho uhlelo luphuma. Ezinye zishiya imithetho yesihlungi kuze kube yilapho okuthile ikususa. Funda inkomba yezilungiselelo zomkhiqizi yohlobo olulisebenzisayo esikhundleni sokucabanga, bese ubhala phansi ukuthi iyiphi kwezintathu oyihlolayo.
Bhala futhi iphrofayili: iphrothokholi, imindeni yamakheli nokuthi umhubhe ohlukanisiwe uvuliwe yini. Isimangalo sokuthi kuhlanganiswa idivayisi yonke asinanjongo uma iphrofayili ngamabomu ingafaki izinhlelo ezimbalwa, futhi ukukhishwa owakuhlela wena uqobo akulona ukuvuza. Inkomba yezilungiselelo ye-OpenVPN Connect iwuhlobo lwekhasi elisho ukuthi iyiphi iswishi eshintsha ukuziphatha okuthile, nakuba amalebula ehluka kuklayenti ngakunye.
Khetha indawo yokukhohlisa esebenza futhi ngaphandle komhubhe
Ukukhohlisa kudinga izici ezimbili, futhi ukweqa enye yazo kunikeza umphumela ongafundeki. Kufanele kufinyeleleke ngqo lapho umhubhe uphansi futhi ukuvinjwa kucishiwe, ngaphandle kwalokho ukuthi kuyekile ukuphendula kungase kusho nje ukuthi umgcini wendawo unyamalele. Futhi akufanele kudinge ukungena, ikhukhi noma inkokhelo, ukuze ukuvuza kubize umugqa owodwa wokuloga esikhundleni seseshini.
Ikhasi elingaguquki kumgcini wendawo oyilawulayo iyisinqumo esihlanzekile kakhulu. Umshini wengqondo oyisipele osebenzisa iseva evamile ye-HTTP ucishe ube muhle ngokufanayo, futhi ikhasi lomphakathi lokuhlola ukuxhumana liyasebenza uma wamukela ukuthi ukutholakala kwalo kungaphandle kokulawula kwakho. Bhala ikheli, imbobo, umndeni wamakheli nokuthi isicelo sidinga ukusesha igama yini, ngoba ngakunye kulokhu kuba ukuguquguquka okungase kudingeke ukukwehlukanisa kamuva.
Sungula umugqa oyisisekelo ngaphambi kokuthinta iswishi. Uma umhubhe uphakeme, ukukhohlisa kufanele kuphendule ngomhubhe, okufakazela ukuthi umzila wenqubomgomo uyasebenza. Uma umhubhe uphansi futhi ukuvinjwa kucishiwe, kufanele kuphendule ngqo, okufakazela ukuthi indawo iyaphila. Kulapho kuphela ukwehluleka esimweni esivinjiwe kungakutshela okuthile.
Yenza ukudlula ngokulandelana okungaguquki
Thatha ukudlula ngakunye futhi unikeze ngakunye imizuzwana embalwa yokuthula, ngoba amaklayenti avame ukudiliza futhi akhe kabusha imithetho kulelo gebe. Ukwenza ukuhlola okufanayo okufushane njalo kwenza okubonakalayo kuqhathaniseke:
curl -sS -o /dev/null -w 'http=%{http_code}\n' --max-time 5 http://decoy.example/
echo "curl_exit=$?"
dig +short decoy.example
curl -6 -sS -o /dev/null -w 'v6_http=%{http_code}\n' --max-time 5 http://decoy.example/
echo "curl_v6_exit=$?"| Transition | Expected with the block on | Failure signature |
|---|---|---|
| Manual disconnect | Decoy stops answering within seconds | Decoy still returns 200 |
| Server or path failure | Blocked, with no exemption for the old endpoint | Direct access during the gap |
| Quit the app | Client-dependent; record what happens | Block disappears with the process |
| Wi-Fi to Ethernet | Block holds until the tunnel returns | Traffic flows mid-change |
Umugqa wokuphuma kuhlelo ufanele ukwenziwa ngokwahlukile ngisho noma ungakaze uvale iklayenti ekusetshenzisweni okujwayelekile. Uma ukuvinjwa kudedelwa ekupheleni, ukuphahlazeka noma ukubuyekezwa okuphoqelelwe kukunikeza ukuchayeka okufanayo, futhi lokho kuyiqiniso mayelana nokufakwa, hhayi mayelana nokubekezela kwakho. Ku-Windows, izivivinyo ezilinganayo yi-Resolve-DnsName decoy.example ne-curl.exe -s -o NUL -w "%{http_code}" http://decoy.example/.
Hlukanisa ukuvinjwa kusixazululi esiphukile
Ikhasi elingalayishi liba nezimbangela ezimbalwa, futhi kube kukhona eyodwa kuphela eyiswishi esebenzayo. Uma igama lingaxazululeki, uthole ukuthi i-DNS ivinjiwe noma iphukile, hhayi ukuthi indlela yedatha ivinjiwe. Linga futhi ikheli elingqo, ukuze impendulo inganciki nhlobo ekuxazululeni.
Amakhodi okuphuma e-curl ahlukanisa lezo zimo. U-6 wukwehluleka kokuxazulula igama, u-7 usho ukuthi ukuxhumana kunqatshiwe, u-28 isikhathi sokuphela. Umzila ovinjiwe uvame ukuvela njengokuphela kwesikhathi noma ukunqatshwa kwikheli elingqo, kanti ukuvinjwa kwe-DNS kuphela kushiya u-6 futhi kufihle konke okunye. Ikhasi elilondolozwe ku-cache noma ingosi ebambayo ikhohlisa iso, ngakho ubufakazi yikhodi yokuphuma, hhayi isikrini.
Phinda ukuhlola nge-IPv6 usebenzisa ikheli elingqo. Ukuvinjwa okuhlanganisa i-IPv4 futhi kunganaki i-IPv6 kuvamile ngokwanele ukuthi kufanele umugqa wakho ezindebeni zakho, futhi iklayenti elicisha i-IPv6 ngaphandle komhubhe kufanele lehluleke kahle kuyo yomibili imindeni.
Bhala ububanzi okuhlanganiswa umphumela
Uma umhubhe ubuyile, qinisekisa ukululama: ukukhohlisa kuphendula ngomhubhe, isixazululi sibuyisela izimpendulo, futhi inqubomgomo ihlezi lapho uyishiye khona. Bese uhoxisa izivivinyo. Umthetho wesikhashana we-firewall, umzila wokulungisa amaphutha noma iphrofayili yokuhlola okushiywe endaweni kuzodida ukugijinywa okulandelayo futhi kungase kuphile isikhathi eside kunohlelo.
Ukudlula okukodwa kuhlanganisa uhlobo olulodwa lweklayenti, iphrofayili eyodwa, ukudlula okukodwa nomndeni wamakheli owodwa. Bhala lezo zine kanye nomphumela:
- Uhlobo lweklayenti nepulatifomu, nokuthi isilungiselelo sisebenza ngephrofayili noma ngokujwayelekile.
- Iphrofayili, iphrothokholi nanoma yikuphi ukukhishwa komhubhe ohlukanisiwe.
- Ukudlula okuhloliwe nokuthi wakucupha kanjani.
- Imindeni yamakheli ne-DNS, namakhodi okuphuma e-curl wesimo esivinjiwe nesingavinjiwe.
Uma noma yimuphi umugqa ungenalutho, isivivinyo asikapheli. Ukuzulazula kusho ukuphinda umugqa woshintsho lwenethiwekhi. Ukuqalisa kabusha okungagadiwe kusho ukuhlola ukuthi imithetho iyabuya yini, futhi lowo umbuzo mayelana nokulandelana kokubuyisela, hhayi ngeswishi. Phinda ukulandelana ngemva kokubuyekezwa kweklayenti, ngoba izwishi azivamile ukushintsha kuyilapho ukuziphatha ngemuva kwazo kushintsha. Gcina ukukhohlisa: akukho okumele kujikeleziswe futhi ukuhlola okulandelayo kuthatha imizuzu emihlanu.
