Igateway noma iklayenti elidlulisiwe? Ukufunda ikheli lomthombo

Iseva yewebhu iqopha ikheli elilodwa, futhi wonke umuntu ucabanga ukuthi lingele nqubo yegesi ngokwayo. Lingase libe leklayenti elidlulisiwe elilahlekelwe yikheli lalo langasese esigabeni sokuhumusha. Indawo okuyiwa kuyo ibona umthombo wenethiwekhi obonakalayo futhi akukho okunye. Lesi isitatimende esimayelana nomngcele, hhayi isimangalo sokuthi umsuka awunakho ukutholakala nanini.

Lokho indawo okuyiwa kuyo ekubonayo ngempela

Thatha iklayenti eliku-10.20.0.7, igesi elinekhali langaphandle elingu-198.51.100.10, kanye nendawo okuyiwa kuyo ku-inthanethi. Uma igesi ihumusha umthombo weklayenti, isokhethi yendawo okuyiwa kuyo iqopha u-198.51.100.10. Ikheli langasese liyanyamalala ephekini, futhi indawo okuyiwa kuyo ayikwazi ukulifunda futhi kusukela kuleyo khanda. Lezi zinombolo ziyizibonelo, hhayi ukuthwetshulwa okuvela kunethiwekhi yakho.

Ukwaziswa kusalusizo: kukhombisa umthombo wenethiwekhi okumele indawo okuyiwa kuyo ivume noma ivimbe. Ayikhombisi nje umuntu noma inqubo engemuva kwawo. Kumqhubi wendawo okuyiwa kuyo, lowo mehluko unquma ukuthi ukuvimbela kuyisinqumo senethiwekhi noma isinqumo se-akhawunti.

Isimo sokuhumusha asibonakali endaweni okuyiwa kuyo

Igesi igcina imephu phakathi koxhumano oluhunyushiwe neklayenti lokuqala, futhi yilowo simo esingekho endaweni okuyiwa kuyo. incazelo yendabuko ye-NAT ihlukanisa irekhodi lokuhumusha kusuka kumakhanda abonakala kamuva. Ukufunda uhlangothi olulodwa akukuniki olunye.

Imiklamo ehlukene iletha ubufakazi obuhlukene. Ithrafikhi eqondisiwe enamakheli omthombo agciniwe ibonisa ikheli langempela leklayenti, kuyilapho i-proxy yohlelo lokusebenza iqeda uxhumano futhi yakhe olunye. Umzila onomthombo ogciniwe nawo udinga ukuthi ikheli leklayenti likwazi ukuqondiswa libuyele emuva lisuka endaweni okuyiwa kuyo, okuyinto angewona wonke umsebenzi wokuthunyelwa oyinikezayo. Buza ukuthi yimuphi umklamo osetshenzisiwe ngaphambi kokuhumusha umugqa werekhodi.

I-TTL nezimpawu zeminwe ziyizinkomba, hhayi ubufakazi

I-TTL ku-IPv4 incike enanini lokuqala elikhethwe umthumeli kanye nenani lamagxathu i-pheki eliwadlulile. Ngaphandle kwala maqiniso womabili, inani alikwazi ukufakazela ukuthi kwenzeke igxathu le-VPN. Igxathu elengeziwe eliqondisiwe elaziwayo nalo alikwazi ukuhlukanisa i-router ye-LAN, umzila womhubhe noma olunye uhlelo lokudlulisa. Thatha umehluko we-TTL njengombuzo, hhayi isiphetho.

Ezinye izimpawu zenzeka ngendlela efanayo. Ikhanda le-User-Agent lingasetwa uhlelo lokusebenza, futhi ukufana kwesikhathi kungabonisa ingqalasizinda eyabiwe hhayi umuntu oyabiwe. Abasebenzisi abaningi bangabelana ngokuphuma okukodwa, futhi umsebenzisi oyedwa angashintsha indlela phakathi kwemihlangano. Uma ziqoqwa ndawonye, izimpawu ezimbalwa ezibuthakathaka zingase zithethelele ukubheka eduze amarekhodi egesi, kodwa aziphenduki zibe ubufakazi obuqinile ngokuqoqwa.

Gunyaza ngobunikazi, hhayi ngekheli

Uma indawo okuyiwa kuyo kufanele yehlukanise ukuphathwa kwegesi nomsebenzi womsebenzisi okude, nikeza lezo zindima ubunikazi obuqinisekisiwe obuhlukene kanye nemisebenzi evunyelwe. Umthombo womphakathi owabiwe usengasebenza njengomkhawulo wenethiwekhi, kodwa awuthathi indawo yokuqinisekisa umsebenzisi noma idivayisi.

Gcina ubufakazi bulebuliwe: umthombo obonwayo, i-akhawunti eqinisekisiwe, isikhathi kanye nesiphetho esicatshangelwayo. Ungahumushi «akukho mthombo wangaphakathi obonakalayo lapha» njengokuthi «akukho ukuxhumaanisa okungenzeka ndawo yonke». Ilebula libalulekile lapho umuntu owayengekho ophenyweni efunda irekhodi ezinyangeni eziyisithupha kamuva.

Qopha usuku lokwaziswa kanye nohlelo olukhiqize. Ingxenye yerekhodi engenakho ukuxhumaanisa inzima ukuyivikela kamuva.
