Indlela yokuhlola isivinini se-VPN ukuze izinombolo zisho okuthile

Ukuhlolwa kwesivinini akukaze kukale i-VPN ngokwayo. Kukala indlela, futhi ukuvula umhubhe kushintsha ingxenye yaleyo ndlela ngaphambi kokuba ibhayithi yokuqala inyakaze. Yingakho ikhompuyutha ephathekayo eyodwa ibonisa inombolo enempilo kusayithi eyodwa kanye nenombolo embi kwesinye, ngaphandle kokuthi kukhona okushintshile ohlangothini olulodwa. Funda umphumela njengobufakazi mayelana nomzila, hhayi njengezinkomo zomkhiqizo.

Izinto ezintathu zinquma ukuthi ukuqhathanisa kunenzuzo yini: ukuthi yomibili imigijimo ifike kumgomo ofanayo, ukuthi inethiwekhi yokufinyelela yehlala inganyakazi, nokuthi ubhale ukubambezeleka kanye nomthamo.

Yini umhubhe ayibhala kabusha ngaphambi kwebhayithi yokuqala

Iklayenti isonga iphakethe ngayinye kunhlokophezulu enye, ngakho umthwalo owusizo ngephakethe ngayinye uyancipha. Izindleko zingezephakethe ngayinye, hhayi zokudlulisela, okusho ukuthi ifayela elikhulu lidinga amaphakethe amaningi kunalelo fayela elifanayo elithunyelwe ngaphandle komhubhe. Umthwalo onjalo ubonakala njengenani lamaphakethe, hhayi njengesethingi ebonakalayo.

Kulandela imiphumela emibili. Ukuhlolwa okwakhiwe ngamabhuloki amakhulu kuzwa izindleko zephakethe ngalinye, kuyilapho ukuhlolwa okwakhiwe ngezicelo ezincane eziningi kuzwa uhambo lokubuya ngemva kwesikhathi. Futhi uma ukutholakala kwe-MTU yendlela kuvinjiwe endaweni ethile endleleni, umhubhe uthula kusayizi wephakethe elincane futhi ukusakazwa kuyehla ngesizathu esingenakho ukuxhumana nokubethela.

Ungabona uphahla ngqo. Ku-Linux cela umthwalo omkhulu kunayo yonke odlula ngaphandle kokuhlukaniswa, bese uphinda umhubhe uvuliwe:

ping -M do -s 1472 -c 3 203.0.113.10

Uma lokho kuhluleka, yehla uye ku-1,400 bese uzama futhi. Umhubhe othwala kuphela amabhayithi angu-1,380 ukutshela ukuthi kukhona okucindezela phansi kakhulu endleleni, futhi akukho ukulungisa kuklayenti okuyokukhuphula.

Kungani iseva yokuhlola isuka endaweni lapho umhubhe uvuleka

Amathuluzi amaningi akhetha iseva eseduze ngokusekelwe ekhelini lomphakathi alibonayo. Uma umhubhe uvuliwe, lelo kheli lingelendlela yokuphuma, ngakho ithuluzi lingakhetha umsingathi kwelinye idolobha noma ezweni. Khona-ke uqhathanisa izindawo ezimbili, futhi igebe phakathi kwazo lihlanganisa ibanga ukusuka ekuphumeni kuya kumsingathi wokuhlola.

Bopha iseva ngegama noma nge-ID ngaphambi komgijimo wokuqala futhi uyigcine kuwo wonke umgijimo olandelayo. Uma ithuluzi lingayigcini, khetha umgomo owulawulayo futhi uyiqhube ngokwakho: iperf3 -c test.example.net -R -t 20 igcina indawo inganyakazi futhi ikunikeza inombolo ongayiqhathanisa neyayizolo.

Shintsha ukuguquguquka okukodwa, ingqimba engezansi ayiyodwa

Okungenantambo inguquko ejwayelekile ecashile. Amandla esignali ayashintsha uma ikhompuyutha ephathekayo inyakaza futhi ukugcwala kwesiteshi kuyashintsha uma umakhelwane eqala ucingo, ngakho imigijimo emibili ehlukaniswe ngemizuzu eyishumi ku-Wi-Fi akuyona ukuphindwa kokuhlolwa okufanayo. Ikhebula, noma indawo eboshiwe enezinga lesignali elibhaliwe, isusa ingxenye enkulu yalowo msindo. Ukubhala izinga lesignali ekuqaleni nasekupheleni komgijimo ngamunye ngokuvamile kwanele ukukhombisa ukuthi imigijimo emibili ihamba ndawonye yini.

Umthwalo wedivayisi nawo usengqayini efanayo. Iklayenti ebethela emkhostini owodwa ifinyelela uphahla lwayo ngaphambi kwesixhumanisi, futhi ukuvumelanisa kwangemuva kufinyelela ngaphambi kwalokho. Qaphela i-CPU phakathi nomgijimo futhi ubhale nokunye obekuvuliwe. Izilungiselelo zamandla nawo angaluma lapha, ngoba ikhompuyutha ephathekayo esebenzisa ibhethri ingakhawulela umshini wokucubungula ngaphambi kokuba isixhumanisi sisondele ekugcwaleni.

Gcina ingqimba engezansi inganyakazi esikhundleni sokuthatha isilinganiso phezu kwayo. Imigijimo emithathu evumelanayo isho okuningi kuneyishumi eyenziwe emakamelweni ahlukene.

Ukubambezeleka, ukulahlekelwa kanye ne-ICMP kuphendula imibuzo ehlukene

I-ping ithumela uphenyo oluncane ekhelini eliboshiwe, futhi izinethiwekhi eziningi ziphendula i-ICMP ngokubaluleka okuphansi noma ziyidelele ngokuphelele. Izimpendulo ezingekho zichaza uphenyo, hhayi amaphakethe ohlelo. Isikhathi sokuhamba nokubuya esikhuphuka ngaphansi komthwalo ngokuvamile sisho ukuthi umugqa uyagcwala, hhayi ukuthi indlela yaba yinde.

Ukuze wazi ukuthi umhubhe wengeza ukubambezeleka yini, qhathanisa umgomo owodwa nawo nangaphandle kwawo, noma qhathanisa ukuphuma okubili okufinyeleleka kunethiwekhi yokufinyelela efanayo. Qhuba uphenyo ngokuphindaphindiwe futhi ubheke ukusatshalaliswa, ngoba isilinganiso sicasha ukuguquguquka okwenza ucingo lungasebenzi.

Buyela emsebenzini owanikeza umuzwa wokuthi uyahamba kancane

Isilinganiso esithuthukayo ngenkathi ucingo lusadilika siphendule okunye. Qhuba futhi umsebenzi owaqala uphenyo, kungaba umhlangano, ukwabelana ngefayela noma isikhathi sedesikithophu ekude. Uma inombolo ithuthuka kepha umsebenzi awuthuthuki, ibhodlela lalikhona lapho ukuhlolwa kungakafiki khona, njengesiseva esingemuva komhubhe noma isixhumanisi sakho sokulayisha.

Bhala umgijimo ngamunye nedivayisi, inethiwekhi yokufinyelela, iphoyinti lokugcina, iphrothokholi, umgomo nesikhathi. Umgijimo ongakaze uxhume umphumela wokufinyeleleka hhayi ukusakazwa okungu-zero, ngakho gcina ngaphansi kwalelo lebuli esikhundleni sokuwususa.

Uhlu olufushane ngaphambi kokuqhathanisa okulandelayo

Bopha umgomo futhi ubhale ukuthi kungani wawukhetha. Bhala usayizi wephakethe ovunyelwe yindlela, ukuze ukwehla kamuva kube nencazelo. Gcina inethiwekhi yokufinyelela ifana, bhala umthwalo we-CPU, futhi uthathe imigijimo emithathu ngaphambi kokukholwa umehluko.

Bese ushintsha into eyodwa ngqo futhi uphinde. Ukuqhathanisa ongakuchaza kungcono kunalokho okunenombolo enkulu.
