I-SSTP iyi-PPP phezu kwe-HTTPS, hhayi ikhasi lewebhu kumbobo 443

SSTP ithwala i-PPP ngaphakathi kokuxhumana kwe-HTTPS, yingakho ibonakala njengethrafikhi yewebhu kunoma yini ephakathi. I-TLS ne-HTTP zakha umzila wangaphandle, bese kuthi imilayezo yokulawula ye-SSTP ilungiselele umhubhe, futhi i-PPP inikeze ukuziphatha kwesikhathi. Isiphequluli esilayisha ikhasi ekhelini elifanayo siqede ingxenye yesigaba sokuqala kuphela. Ukukuthatha lokho njengokuhlolwa kwe-VPN yikho okwenza iphroksi esebenzayo ibekwe icala ngokungafani kweprotocol.

Hamba izigaba ezine ngokulandelana, futhi ukwehluleka okubonayo kuzowela kwesinye sazo.

Isigaba 1: i-TCP ne-TLS

Iklayenti livula ukuxhumana kwe-TCP embobeni 443 futhi lenze ukuxhawana kwezandla kwe-TLS. Uchungechunge lwesitifiketi kufanele luhambisane negama lomsingathi iklayenti elalilungiselelwe lona. Ukungafani kwegama lapha kudala ukwehluleka ngaphambi kokuba noma yimuphi umlayezo we-SSTP ushintshwe, futhi isicaciso se-SSTP sicabanga ukuthi lo mzila wangaphandle we-HTTPS usekhona. Akukho lutho ezigabeni ezilandelayo okungakwazi ukunxephezela ukwehluleka kokuthembela lapha.

Iseva yewebhu evamile ingaqedela lesi sigaba ngokuphelele futhi yehluleke kwesilandelayo. Impumelelo ye-TLS iwubufakazi mayelana nesitifiketi, hhayi mayelana neprotocol engemuva kwaso.

Isigaba 2: isicelo se-HTTPS

I-SSTP yenza isicelo sayo ngendlela ethile, i-SSTP_DUPLEX_POST, futhi igcina ukushintshana kuvuliwe esikhundleni sokubuyisela idokhumenti. Iseva noma iphroksi elilungiselelwe izicelo zamakhasi avamile lingamukela ukuxhumana bese lenqaba indlela. Lokho kunqaba yinkinga yokuhambisana abantu abayichaza ngokujwayelekile njengombobo 443 ovinjiwe.

Funda ikhodi yempendulo nendlela kulogi yeseva. Ukunqaba kulesi sigaba kuyinkinga ehlukile kunokuphela kwesikhathi kwe-TCP, futhi kokubili kuholela ekulungiseni okuhlukile.

Isigaba 3: imilayezo yokulawula

Lapho isicelo sesamukelwe, i-SSTP ishintshanisa imilayezo yokulawula exoxa futhi ilungiselela umhubhe. Le milayezo yeprotocol ngaphakathi komzimba we-HTTPS, hhayi izicelo ze-HTTP, ngakho iphroksi ehlola futhi ibhala kabusha imizimba ingayephula iyishiye izicelo zamakhasi zingathintekile.

Yilapho idivayisi ephakathi yokuhlola okujulile ithola udumo lwayo. Uma amakhasi elayisha kodwa i-VPN yehluleka, hlola ukuthi umzimba uyashintshwa yini hhayi ukuthi umbobo uvuliwe yini.

Isigaba 4: i-PPP ithatha izintambo

Bese i-PPP inikeza ukuziphatha kwesikhathi: ukuxoxisana kwesixhumanisi, ukuqinisekisa kanye nokulungiselelwa kwesendlalelo senethiwekhi okulandelayo. Ukuqinisekisa kwe-PPP kuhlukile ekuhlolweni kwe-TLS iklayenti elisephule kakade. Isitifiketi seseva iklayenti elisamukelayo asisho lutho mayelana nokuthi imininingwane yokungena yomsebenzisi ivumelekile yini noma i-akhawunti igunyaziwe yini.

Isitifiketi esamukelwe nokungena okunqatshiwe akusho ukuphikisana. Lezi yizigaba ezilandelanayo ezinemiphumela ezimele.

Ukuqinisekisa kunendima eziningana

Iklayenti liqinisekisa ubunjalo beseva ye-TLS ngokumelene nesitolo sayo sokuthembela kanye negama elilungiselelwe. Bese i-PPP iqinisekisa umsebenzisi noma umshini, kuye ngokuthunyelwa. Iseva ingangeza inqubomgomo yayo mayelana nokuthi ubani angaxhumana nokuthi yini angayifinyelela. Gcina igama lomsingathi lihambisana nobunjalo besitifiketi, ngoba ukufaka ikheli elingahluziwe esikhundleni salo kuguqula ukulungiselelwa okusebenzayo kube ukwehluleka kokuhlola igama.

Bhala ukuthi yisiphi isigaba esibike ukwehluleka. Isitifiketi, indlela, umlayezo wokulawula, ukuqinisekisa kwe-PPP, bese kuba imizila: izindawo ezinhlanu, ukulungisa okuhlanu.

Okungaboniswa nokungakwazi ukuboniswa ukuhlolwa kwesiphequluli

Ukulayisha ikhasi ekhelini kufakazela ukuxazululwa kwe-DNS, ukufinyeleleka kwe-TCP nokuthi kukhona okulalelayo okukhuluma i-HTTP. Akufakazeli ukuthi indlela yamukelwa, ukushintshana kokulawula kuyaphila noma ukuqinisekisa kwe-PPP kulungiselelwe. Sebenzisa iklayenti elisebenzisa i-SSTP esikhundleni sokuguqula enye iphrofayili ngokushintsha umbobo.

Uma isikhathi sesikhulile, imizila, i-DNS nokudluliswa ohlangothini lweseva kusaqhutshwa ukuthi umsebenzisi angafinyelela ini. Umhubhe uyindlela, akuyona imvume.
