Izindlela ezintathu zokusebenza kuma-VPN amaningi ngaphandle kokudideka

Imisele emibili yamaklayenti, ikhompyutha ephathekayo eyodwa kanye nethebhu yesiphequluli esangena ngemvume endaweni okwakungafanele ibe kuyo. Ingxenye enzima yokusebenza kumanethiwekhi amaningi azimele akukona ukuxhumanisa; ukwazi ukuthi iwindi lingaphansi kwaluphi umongo uma ushintsha. Indawo yokusebenza iphendula lowo mbuzo: ubunikazi obubodwa, iqoqo lolwazi lokusebenza elilodwa, inqubomgomo yesisombululi eyodwa kanye nendawo eyodwa yokubheka uma into isonjululwa ngokungalungile. Ngosuku olubi lokhu kuyimehluko phakathi kokulungisa kwemizuzu emihlanu nokuvuza kwedatha.

Nquma ukuthi umsebenzi ungesikhathi esisodwa yini

Uma impendulo ingu-cha, yima lapha futhi usebenzise ilungiselelo elilula kakhulu elitholakalayo. Ukuxhumana okukodwa okuvunyelwe ngesikhathi esisodwa, okuxhunywa futhi okunqamulwa ngeklayenti eliphethe iphrofayela, kususa ikilasi eliphelele lokwehluleka ngaphambi kokuba noma yikuphi kwazo kwenzeke.

Ukuvumelana kwesikhathi kuyikho okukhulisa izindleko: amaprefiksi agqagqene, izinqubomgomo ezimbili zesisombululi kanye namaqoqo amabili esimo sohlelo kumele kuhlukaniswe ngamabomu, hhayi ngesikhathi.

Bhala isidingo ngobuqotho, ngoba ukufuna ukugwema ukuxhumana kabusha akufani nokudinga womabili amanethiwekhi ngesikhathi esisodwa.

Ukulandelana yilona lungiselelo olushibhe kakhulu

Umsebenzi wokulandelana awudingi ingqalasizinda eyengeziwe, futhi indlela yawo yokwehluleka isesheni ephelelwe yisikhathi hhayi ukungqubuzana kokuhambisa. Isiyalo sisekudlulisweni: qeda umsebenzi, vala lokho okubamba ukuxhumana, nqamula futhi uqinisekise ukuxhumana okulandelayo ngaphambi kokuqala umsebenzi.

Ithebhu yesiphequluli noma itheminali ehlala ivuliwe ayihambi nomongo wayo wenethiwekhi. Isicelo sayo esilandelayo siya lapho umshini uhambisa khona manje, okungenzeka kube yiklayenti elinye.

Faka ilebula kumaphrofayela ngokweklayenti hhayi ngokweprothokholi, futhi ugcine umnikazi wemibhalo yokuqinisekisa ebonakala egameni lephrofayela. Iphrofayela ebizwa ngokuthi work2 ayitsheli muntu lutho ngesikhathi sokushintsha okusheshayo.

Inzuzo yalolu lungiselelo ukuthi kungenziwa ucwaningo lwayo. Ngasiphi isikhathi kunomongo owodwa wenethiwekhi, futhi ilogi ibonisa ukuthi washintsha nini.

Indawo yokusebenza yiklayenti ngalinye ibiza ukuhlukaniswa

Umshini wobuciko noma indawo yokuthuthukisa ekude yiklayenti ngalinye ibeka iklayenti, izinhlelo kanye namagama endaweni eyodwa. Ukushintsha kuba ukushintsha kwewindi esikhundleni sokushintsha kwenethiwekhi, futhi imongo emibili ayikwazi ukuvuza komunye inomunye ngomzila olahlekile.

Lokhu akusimahhala. Manje ugcina izinhlelo ezimbili noma ezintathu, uzilungisa futhi unquma ukuthi amafayela nemibhalo yokuqinisekisa kuhlala kuphi. Umshini wobuciko nawo ufinyelela i-inthanethi ngomsingathi, ngakho indlela yawo yangaphandle iseyindlela yekhompyutha yakho ephathekayo.

Hlola ukuthi iklayenti nanoma iyiphi inqubomgomo yesimo sedivayisi ziyayivumela yini leyondawo ngaphambi kokwakha umkhuba wayo. Iklayenti elenqaba ukusebenza emshinini wobuciko yiqiniso okufanele litholakale kusenesikhathi.

Isango elabiwe liyingqalasizinda

Irotha ehlukile ethwala ithrafikhi ekhethiwe iguqula inkinga ibe umklamo wenethiwekhi. Isebenza kahle uma abantu abaningi bedinga inethiwekhi yeklayenti efanayo, futhi yehluleka uma othile eyithatha njengebhokisi lomlingo eligcina iklayenti ngalinye lihlukene.

Isango elilodwa elishintsha umhubhe walo osebenzayo ingumongo owabiwe oyedwa onomugqa, hhayi amanethiwekhi amaningi azimele. Shono ukuthi ubani angayishintsha, iyiphi imithombo eyisebenzelayo kanye nokuthi kwenzekani uma abantu ababili bedinga amaklayenti ahlukene ngesikhathi esisodwa. Ngaphandle kwaleyo mpendulo isango liba umthombo weziphazamiso ezingenaye umnikazi. Liba futhi indawo lapho othile evala khona buthule ukuhlola ukuze afinyelele usuku lokugcina.

Bhala ukudluliswa emibhalweni

Umhlahlandlela awudingi ukuba yinkimbinkimbi; udinga ukuba ucacile ngokwanele ukuze omunye umuntu akwazi ukuwulandela. Kwi-Linux, isikhala samagama iyinguqulo yobuchwepheshe yomqondo ofanayo, nemigudu yaso kanye nethebula yokuhambisa.

Le mikhiqizo idala isikhala samagama, igijima umyalo ngaphakathi kwaso futhi ibonisa ukuthi yikuphi ukuxhumana okuphethwe yiklayenti ledeskithophu njengamanje:

sudo ip netns add customer-a
sudo ip netns exec customer-a ip route
nmcli connection show --active

Izinhlelo kusamele ziqaliswe ngaphakathi kwesikhala samagama, futhi ukulungiselelwa kwesisombululi ngaphakathi kwaso kuyifayela elihlukile. Ukuhlukanisa imigudu akuhlukanisi ibhodi yokunamathisela, i-ejenti ye-SSH noma isabelo esifakiwe, futhi yilokho ukuvuza abantu abakukhohlwayo.

Khetha ilungiselelo elincane kakhulu eligcina ukwehlukana okudinga ngempela, futhi ugcine ukudlula kubonakala: isihloko sewindi, isikhombisi setheminali, igama lephrofayela kanye nomnikazi wemibhalo yokuqinisekisa kufanele kuvumelane ngaphambi kokuthunyelwa kwanoma isiphi isicelo sangasese.
