Izinga leseva ye-VPN likutshelani ngempela?

Izinga liwukuhleleka komshicileli kuphela. Funda incazelo yalo, hlukanisa ukwethemba nesivinini, bese ulinganisa iphoyinti lokugcina kunethiwekhi yakho.

Izilinganiso zeseva ziyizinombolo umshicileli azibalele uhlu lwakhe, futhi ngayinye isho ngqo lokho umshicileli akunqumayo. Imibhalo emibili ingahlela iphoyinti lokugcina elifanayo ngendlela ehlukile ngaphandle kokuthi namunye abe nephutha. Funda incazelo ngaphambi kokuvumela ukuhleleka ukuthi kukhethele indlela yokuphuma.

Izivivinyo ezingezansi zihlanganisa okufanele kufundwe, okufanele kulinganiswe wena, nokufanele kubhalwe phansi. Zithatha iklayenti esivele lisekela iphrothokholi enikezwa umfakisicelo.

Funda incazelo ngaphambi kokuhleleka

Qala ekhasini lencazelo hhayi etafuleni. Izinga elakhiwe ngesikhathi sokusebenza esimisiwe, inani lamaseshini noma izilinganiso zokudluliswa kuyahlela amaphoyinti okugcina ngalezo zinto, okuyisitatimende esimayelana nomthwalo nokufinyeleleka hhayi ngobumfihlo. Qaphela ukuthi okokufaka kudala kangakanani, ngoba inombolo ebuyekezwa nyanga zonke ichaza umshini ohlukile kunalowo obuyekezwa njalo ngehora. Lapho kungekho ncazelo, inombolo iyithuluzi lokuhlela elinokokufaka okungaziwa, futhi ifanele ukwethenjwa okungako kuphela.

Ubukhulu bubalulekile njengokokufaka. Inani elilinganiswe phakathi kocwaningo lomshicileli nephoyinti lokugcina akusho lutho ngomzila osuka kunethiwekhi yakho, futhi inombolo echaza ukudluliswa okukhulu ayibikezeli ukubambezeleka kokusebenzisana. Ukusha nokubanzi kukodwa kunquma ukuthi inombolo iyasebenza esinqumweni sakho.

Ukwethemba, ukuhambisana nesivinini kuyimibuzo emithathu

Iphoyinti lokugcina elamukela ithrafikhi yakho alibi yindawo enhle yokuyithumela lapho ngenxa yalokho. Umugqa womhlahlandlela ubala imininingwane yokusebenza koxhumano, futhi lokho akusona isiqinisekiso mayelana nokuloga, ubunikazi noma okwenziwa umqhubi ngemethadatha. Ukuhambisana kuwumbuzo ohlukile: iphrothokholi, isethi yezimfihlo kanye nenguqulo yeklayenti kuyahambisana noma cha, futhi asikho isilinganiso esikushintshayo lokho. Isivinini singesithathu, futhi yisona kuphela kwezintathu ongasinganisa kumshini wakho.

Ukuhlukanisa lezi zintathu kuvimbela iphutha elivame kakhulu, okuwukukhetha iphoyinti lokugcina elisheshayo bese ukufunda njengobufakazi bomkhuba omuhle. Iphoyinti lokugcina elihamba kancane kodwa elicacile liwukukhetha okuzenzakalelayo okungcono kunalelo elisheshayo ongakwazi ukuchaza umqhubi walo.

Umhlahlandlela ungashicilela nezinkambu ezingahambisani nanoma yikuphi kwezintathu. Incazelo yomqhubi uqobo, uhlu lwamaphrothokholi noma ilebula lezwe konke kuyizitatimende nemethadatha, futhi kuza nokuthembeka kwalowo okubhalile.

Linganisa umfakisicelo kunethiwekhi yakho

Lapho umfakisicelo esedlulile imibuzo emibili yokuqala, linganisa umzila ozowusebenzisa ngempela. Imiyalo engezansi ihlola ukufinyeleleka, izinga lomzila kanye nesicelo esiqediwe, ngalokho kuhleleka. Yisebenzise ngehora ozosebenzisa ngalo isevisi, ngoba ukuxhumana kwasekhaya nokudluliswa komphakathi kuyashintsha ngomthwalo.

ping -c 20 203.0.113.77
mtr -r -c 50 203.0.113.77
curl -sS -o /dev/null -w '%{http_code} %{time_connect} %{time_total}\n' --max-time 8 https://example.com/
timeout 5 bash -c 'cat < /dev/null > /dev/tcp/203.0.113.77/1194' && echo port-open

Funda okukhiphayo njengezimpendulo ezintathu ezihlukile. I-ping engaphenduli neze ingase isho ukuthi iphoyinti lokugcina lihlunga i-ICMP hhayi ukuthi isevisi imile, ngakho hlanganisa nokuhlolwa kwembobo. Umkhondo womzila ukhombisa lapho ukubambezeleka kuqoqana khona, futhi isicelo esiqediwe esinesikhathi sifakazela ukuthi uchungechunge lusebenza kusukela ekhelini lakho. Akukho kulawo manani okuyisici saphakade sephoyinti lokugcina.

Bhala ukuqhathanisa phansi

Bhala phansi umfakisicelo, isikhathi sokulinganisa, imiphumela emithathu kanye nesizathu sokudlulela kwesilandelayo. Lokho kuguqula uhlu lwezilinganiso ezikhunjuzwayo lube ukuqhathanisa umuntu omunye angakwazi ukukuphinda. Futhi kuphula umjikelezo wokushintsha amazwe njalo bese uphetha ngokuthi konke kuhamba kancane.

Umfakisicelo ohlulekile nawo ufanelwe umbhalo, ngoba iphoyinti lokugcina elenqaba iphrothokholi eyodwa ngehora elilodwa liyiqiniso ngalolo cwaningo hhayi isinqumo ngomhlahlandlela wonke. Bhala ukwenqaba nesigxivizo saso sesikhathi, futhi ukuqhathanisa okulandelayo kuzoqala ngobufakazi.

Hlola futhi iphoyinti lokugcina elikhethiwe ngemva kwanoma yikuphi ukuthuthukiswa kweklayenti, ngoba impendulo yokuhambisana ingashintsha kuyilapho izinga lihlala linye. Thatha inombolo njengomkhomba wokuhleleka nezilinganiso zakho njengobufakazi.
