Ingabe uhlu olukhulu lwamaseva e-VPN lusho isevisi engcono?
Izibalo zamaseva zihlanganisa amazwe, abasingathi, izimo namaphrofayili, futhi akukho okukodwa okuchaza umzila owudingayo. Izimo ezintathu zinquma ukuthi lokho kubalulekile yini.
Abahlinzeki ababili, omunye ukhangisa amaseva angu-6,000 kanti omunye angu-600, futhi inombolo enkulu izwakala sengathi iningi lento ethile. Empeleni iningi leyunithi engachazwanga. Ngaphambi kokuba inombolo isize ekukhetheni, kufanele kucaciswe izimo ezintathu: ingabe likhona iphuzu lokugcina elisebenza isifunda kanye neprotokholi okudingayo, ingabe umthamo uyahlala phakathi namahora akho okusebenza, nokuthi ubani ophethe ingqalasizinda nokuthi iqopha ini.
Izimo ezintathu ezinquma impendulo
Okokuqala ukufaneleka. Ukufakwa kuhlu lwemibhalo kusiza kuphela uma kwamukela iklayenti lakho, kunikeza iprotokholi oyidingayo futhi kusesifundeni esithuthukisa indlela eya endaweni oya kuyo ngempela. Uhlu lwezinkulungwane zamaphuzu okugcina ezifundeni ongazisebenzisi neze luyinombolo encane kunokuba kubonakala.
Okwesibili umthamo ngesikhathi owudingayo, lokho akufani nomthamo uwonke. Iqembu elikhulu lisingagcwala kakhulu eminyango emibili eseduze nawe ngamahora osebenza ngawo, futhi iqembu elingenzi lutho ngaphesheya komhlaba alisizi.
Okwesithathu ubunikazi nokugcinwa. Ubukhulu bengqalasizinda abusho lutho ngokuthi ubani ophethe isevisi, iqopha ini noma ingabe iklayenti liyanakekelwa. Lona umbuzo wenqubomgomo onezincwadi zobufakazi, hhayi inombolo ekhasini lokufika.
Zontathu kufanele zibe yiqiniso ukuze inombolo ibe nencazelo, futhi ngayinye ingahlolwa ngokwehlukana. Leyo yingxenye ewusizo: isinqumo asidingi ukuthemba isihloko nhlobo. Ungaqinisekisa isimo ngasinye ngemigomo yakho. Noma ubani obhala izimpendulo ezintathu wenza umsebenzi omningi kunencwajana.
Inombolo yesihloko ibala ini
Izinto ezine ezikuleli thebula ngenhla zivame ukuhlanganiswa ekufanisweni okukodwa, futhi izinombolo ezinkulu kakhulu zivame ukuvela kuyunithi okulula kakhulu ukuyikhulisa. Izimo ze-container zishibhe ukudala futhi zingabelana isixhumanisi esisodwa somzimba, ngakho ukuzibala kuchaza ukulungiseka kokumiswa hhayi ukwehlukahlukana.
| What the number counts | What it tells you | What it cannot tell you |
|---|---|---|
| Countries or regions | How many jurisdictions have at least one entry | How many independent machines exist |
| Physical hosts | Roughly how much hardware is deployed | Whether any of it is near your destination |
| Container instances | How many configurable endpoints can be issued | Whether they share one upstream path |
| Downloadable profiles | How many configuration files are offered | Whether the endpoints behind them still work |
Lokho akusikho ukungathembeki ngokuzenzakalela. Umhlinzeki okhipha isimo esisha seshini ngayinye uchaza okuthile kwangempela ngendlela asebenza ngayo, futhi inombolo iyincazelo efanele yalowo mshini. Iphutha ukukufanisa nenani lamazwe lomunye umhlinzeki sengathi lezi zinombolo ezimbili zikala into eyodwa, okungeyona into eziyenzayo.
Kukhona nesici sokunakekela okungekho ukubala okumile okungakuthola. Uhlu luguga, futhi iphuzu lokugcina elibonakala litholakala lingasala lenqaba iphrofayili oyinikiwe. Uhlu lwemibhalo luyiqoqo labazongenela ukhetho okufanele kuqinisekiswe, hhayi uhlu lwezinketho ezisebenzayo. Thatha uhlu njengesimangalo, hhayi njengeqiniso. Ukuqinisekisa okubhalisiwe okubili kuthatha imizuzu eyishumi futhi kuxazulula umbuzo.
Hlola umzila owudinga ngempela
Khetha amaphuzu okugcina amabili angabazongenela ukhetho esifundeni okukhathazayo bese ukala umzila ukusuka ekuphumeni kuya kusevisi oyisebenzisayo. Ukubambezeleka okuya kusango le-VPN yinombolo abahlinzeki abathanda ukuyicaphuna, futhi iyona engathakazelisi kakhulu, ngoba isusa ingxenye yohambo evame ukudala inkinga.
mtr -rwc 20 203.0.113.9
curl -o /dev/null -s -w '%{time_connect} %{time_starttransfer}
' https://example.net/Ukulandelela kubika ukuthi ukubambezeleka kuvela kuphi kulo lonke umzila, igxathu negxathu, okuhlukanisa ukuphuma okukude nokugcwele. Ukulinganisa isikhathi nge-curl kuhlukanisa ukusungulwa koxhumano nokubhayithi yokuqala yempendulo, ngakho ukuxhawulana okunensayo neseva enensayo akuxutshwa.
Qhuba ukufanisa ngamahora osebenza ngawo ngempela, futhi ubhale iphuzu lokugcina, ikheli lokuphuma kanye nendawo oyihlolile. Umphumela ongenazo lezi zinto ezintathu awukwazi ukuphindwa ngemuva kweviki, ngisho nguwe.
Gcina enye indlela esebenzayo emisiwe ngekheli layo neprotokholi eqondile. Inani lokuphindisela lilinganiswa ngosuku lapho okokuqala kuyeka ukusebenza, futhi lolo usuku lapho kungekho muntu ofuna ukufunda uhlu lwemibhalo.
Finyeza uhlu, bese unquma ngobufakazi
Yehlisa ukufanisa kube abahlinzeki abathathu noma abane abaphasa ukuhlolwa kokufaneleka, bese ubahlola ngezindlela ongazenza ngempela. Uhlu olufushane luphoqa imibuzo uhlu olude olukuvumela ukuyigwema, futhi lwenza ukushintshana kucace esikhundleni sokukulinganisa kube ukuthanda okukodwa.
Bhala ubufakazi ngendlela omunye angabukhipha imibhalo ngayo: isifunda neprotokholi oyidingayo, amaphuzu okugcina owahlolile, amahora osuku kanye nokushiwo ukulandelela. Engeza amaqiniso enqubomgomo owakuqinisekisa, nemihla, ngoba izitatimende zokugcinwa ziyashintsha futhi ukucaphuna okungenalo usuku akusibufakazi.
Bese wamukela isiphetho esisekelwa ubufakazi, futhi ngokuvamile sincane kunomnqobi. Umhlinzeki oyedwa angaba ngcono esifundeni sakho ngamahora akho, omunye abe ngcono ngeprotokholi oyidingayo kuklayenti elithile, futhi akukho kulokhu okubili okutholwa ubukhulu buhlu.
Inombolo ayilutho; iyisikhombisi esiqinile mayelana nokutshalwa kwezimali. Iba yisimangalo sekhwalithi kuphela ngemuva kokuba othile echaze iyunithi, eqinisekisa ukuthi amaphuzu okugcina ayasebenza futhi ekhombisa ukuthi umzila oqondile owudingayo ungcono. Kuze kube yileso sikhathi isekholomu yokumaketha, hhayi ikholomu yesinqumo.
