Kungani ukhiye omkhulu we-OpenVPN ungayisusi isibali sikhathi sokuvuselela ukhiye
Amandla okubhala kanye nempilo yokhiye yizinqumo ezihlukene. Hlola izibangeli zamabhayithi, amaphakethe nesikhathi, bese uhlola ukuvuselela ukhiye ohlelweni lwangempela lokungena.
Ukukhetha i-AES-256 noma ukhiye omude akusho lutho mayelana nokuthi lowo khiye ungasetshenziswa isikhathi esingakanani. Amandla okhiye achaza i-algorithm; inqubomgomo yokuvuselela ukhiye yiyo enquma ukuthi isikhathi sithola nini impahla entsha yokhiye. Ukusetshenziswa kungakhetha isihlanganisi esinamandla kakhulu esitholakalayo futhi kube nephutha mayelana nokuvuselelwa, ngoba lezi zinqumo ezimbili zithathwa ezindaweni ezihlukene. Ukuzihlanganisa kuletha ushintsho lwesihlanganisi olungadingekile noma isikhathi esiphila ngokuthula ngale kwenqubomgomo yaso.
Funda izilungiselelo zokuvuselela ukhiye ngaphambi kokuthinta isihlanganisi, futhi ufunde izinhlangothi zombili uma wenza lokho.
Amandla okhiye nempilo yokhiye kuphendula imibuzo ehlukene
Isihlanganisi nosayizi wokhiye bakhawulela ukuthi ukuhlasela kwethrafikhi eboshiwe kungabiza kangakanani. Isikhawu sokuvuselela ukhiye sikhavulela ukuthi ukhiye owodwa uvikele ethrafikhi engakanani nokuthi ukhiye oveziwe uhlala uwusizo isikhathi esingakanani. Lezi yizilawuli ezizimele, futhi isihlanganisi esinamandla akwandisi impilo ephephile yesikhathi. Iningi leziqondiso ezithi 'sebenzisa i-AES-256' alikhulumi ngokuvuselelwa, ngoba ukuvuselelwa kuyindaba yenqubomgomo hhayi ukukhethwa kwe-algorithm.
Bhala kokubili kumanothi okusetshenziswa: yini evikela umzila wedatha, futhi yini ebangela ukushintshwa kokhiye bawo.
Ukuvuselela ukhiye kunezibangeli ezintathu, futhi noma yiluphi uhlangothi lungazivula
OpenVPN 2.6 ibhalisa izibangeli ezihlukene zokuxoxisana kabusha ngokusekelwe kumabhayithi, amaphakethe nesikhathi esidlulile. Isibangeli sesikhathi yiso esishiywa yiningi lokusetshenziswa kusimo esizenzakalelayo, okusho ukuthi ithumelo elithule lisavuselela ukhiye ngokohlelo. Noma yiluphi uhlangothi lungaqala ukushintshana, futhi uhlangothi olungaqalanga luyalandela. Ngakho ukushintsha isibali sikhathi ohlangothini olulodwa akukubeki ukuziphatha kwesikhathi; inani elisebenzayo ngelolohlangothi oluqala kuqala.
Izibangeli zamabhayithi namaphakethe zibalulekile emithwalweni enezinga eliphezulu noma emaphaketheni amancane, lapho inqubomgomo yesikhathi kuphela ingavumela ukhiye owodwa ukuthi uvikele idatha eningi kakhulu kunalokho obekuhlosiwe. Uma lezo zibalokazi zihlala zivaliwe, shono lokho ngamabomu kumanothi esikhundleni sokushiya okusizenzakalelayo kungahloliwe.
Ukuvuselela ukhiye kudala ukuthi umzila wokuqinisekisa ubonakale
Ukuxoxisana kabusha iwukuxhawula kwe-TLS okusha, okusho ukuthi indlela yokuqinisekisa iyasebenza futhi. Ukusetshenziswa okusebenzisa amakhodi okusetshenziswa kanye, amathokheni ezingxenyekazi noma inselelo ye-RADIUS kuthola lokhu ngendlela enzima: uxhumano lokuqala luyasebenza bese isikhathi sifa ngemuva kwehora lapho ukuxhawula kwesibili kucela ikhodi esivele isetshenzisiwe. auth-gen-token likhona ukuvala lelo gebe ngokuvumela iseva ukuthi likhiphe ithokheni yesikhashana elifushane lokuxoxisana kabusha esikhundleni sokufuna ukungena okusebenzisanayo okusha.
Kubheke lokhu njengenkinga yokuhamba komsebenzi okufanele ixazululwe nomsebenzi, hhayi njengobufakazi bokuthi ukuvuselelwa kufanele kucishwe.
Hlola ukuvuselelwa ngaphansi komthwalo, hhayi esikhatheni somzuzu owodwa
Ukuhlolwa kokwamukela okuxhuma, kwenze i-ping kanye bese kunqamula akukaze kufinyelele ekuvuseleleni ukhiye. Qhubeka nesikhathi eside ngokwanele ukweqa isibangeli esilungisiwe, gcina ukudluliswa kuqhubeka phakathi naso sonke isikhathi, futhi ubheke amarekhodi ezinhlangothi zombili ukuthola ukuxhawula okusha. Bese uhlola indlela yokuhluleka: ukuthi iklayenti lenza ini uma ukuxoxisana kabusha kungenakuphela. Ithumelo eliwela ngokuhlanzekile kulula ukulihlola kunalelo eliqhubeka lithumela esikhatheni esifile.
Ungakufundi ukudluliswa okukhulu okuphumelelayo njengobufakazi bomkhawulo we-cryptographic. Kukhombisa kuphela ukuthi indlela nezibalokazi zikwazile ukubekezelela leyo thrafikhi.
Bhala zombili izinqumo
Irekhodi lidinga imigqa emibili: ukuthi amaphakethe avikelwa kanjani, nokuthi lolo vikelo lushintshwa nini. Engeza igunya lenani ngalinye, ngoba isihlanganisi singavela kusimo esizenzakalelayo sokusabalalisa kuyilapho isibali sikhathi sivela kunqubomgomo yangaphakathi. Umsebenzi wesikhathi esizayo akufanele kudingeke ukuthi acabangele noma yikuphi kwalokhu kusuka kufayela lokucushwa.
Uma ukuhambisana kuphoqa ukuhlukile, kukhawulele kunguqulo olulodwa nosuku lokuphela. Ukuhlukile oluphila isikhathi eside kunesizathu saso luba inqubomgomo okungekho muntu okhumbulayo ukuthi wayikhetha.
