Iphutha 809 liyinkinga yomzila ngaphambi kokuba yinkinga yokungena

Izimo ezintathu zinquma ukuthi iphutha 809 likutshelani: ukuthi iphrothokholi yephrofayela iyileyo ocabanga yona, ukuthi umzila uyivumela yini leyo phrothokholi ukuba idlule, nokuthi ingemuva liyibonile yini imizamo. Kuze kube yilapho lezi ziphendulwa, iphutha liyisikhathi sokuphela, futhi isikhathi sokuphela akusona isinqumo ngemininingwane yokungena. Ukulandelana kubalulekile, ngoba ukushintsha isimo esingalungile kuqala kuchitha ubufakazi bezinye ezimbili.

Icheku elivaliwe nephasiwedi engalungile kukhiqiza imilayezo ehluke ngokuphelele, futhi 809 akuvamile ukuba ngowesibili.

Qinisekisa iphrothokholi esetshenziswa yiphrofayela

Hlola igama leseva, ikheli kanye nohlobo lwethuneli ngokusho kwemiyalelo yamanje yomqhubi, bese ubhala ukuthi lolo hlobo luncike kuluphi ukuthutha. Lawa mavelu amathathu ahambisana; igama elilungile elinohlobo lwethuneli oluphelelwe yisikhathi lehluleka njengoba kwenza igama elingalungile. IKEv2 incike ku-UDP 500 kanye no-4500, futhi ithrafikhi ye-ESP yemvelo kufanele ivunyelwe njengephrothokholi yayo, hhayi njenge-TCP noma i-UDP. Iphrofayela ekopishwe kusethaphu endala ingase ibize uhlobo lwethuneli iseva engasalunikezi. Thola ivelu kumqhubi esikhundleni sokuyicabangela kusukela ilebula elikubhokisi lengxoxo.

Ikhasi lesiphequluli kulelo gama lomsingathi lihlola insiza ehluke ngokuphelele. Lingafakazela ukuthi umsingathi uyaphila futhi alifakazeli lutho mayelana nengxoxo ehlulekile.

Shintsha inethiwekhi, hhayi imininingwane yokungena

Uma inqubomgomo ivuma, hlola iphrofayela efanayo kusukela kwenye inethiwekhi ethembekile, ugcina iklayenti neseva kungashintshwanga ukuze umzila wokufinyelela ube umehluko kuphela. Impumelelo kwenye indawo ikhomba ekuhlungweleni emzileni wokuqala, kuyilapho ukwehluleka kuyo yonke indawo kukhomba ekugcineni noma kwiphrofayela ngokwayo. Buza umqhubi ukuthi ingemuva liyibonile yini imizamo, ngoba iklayenti elingenaso isigameko seseva esihambisanayo iwumngcele ohlukile kunokwenqatshwa okucacile.

Ukushintsha okungahleliwe kurejista nokucisha isivimbelo somlilo kuyiseluleko esidumile kule khodi, futhi akukho kukho okubili okuvela ekuxilongweni okuqinisekisiwe. Buza umqhubi ukuthi yikuphi ukulungiswa okubhaliwe kulokhu kusetshenziswa.

Landela ikhodi kuze kufike isigaba esilandelayo

Uma umzamo wakamuva ufinyelela ekuqinisekiseni futhi ukhiqiza ikhodi ehlukile, landela leso sigaba esisha futhi ushiye ukuxilonga kwesikhathi sokuphela kwasekuqaleni. Ukuthwala inkinga yomzila ekuphenyeni i-akhawunti kuchitha isikhathi kuzo zombili. Bhala iphrothokholi, isigaba esihlulekile nokuthi ngabe ukuqhathaniswa kwenethiwekhi kwenziwe, ukuze umuntu olandelayo aqale ngobufakazi hhayi ngombhalo wengxoxo.

Bheka ikhodi njengophawu lwesigaba, hhayi njengesinqumo; lokho kufunda kumehluko phakathi kokuhlola kwemizuzu emihlanu nentambama elahlekile.

Okungamelwe kushintshwe kuqala

Imininingwane yokungena, isimo sokukhiywa kanye nesitoreji sezitifiketi konke kufanele kunakwe ekugcineni. Akukho kukho okuyindawo lapho 809 ivamise ukuqala khona, futhi ukushintsha okukodwa kuqala kususa ukuqhathaniswa obekuzothola umzila. Gcina lokho kuhlola kwaze kwaba ngemuva kokuhlolwa kwenethiwekhi. Gcina iklayenti, iphrofayela neseva kungashintshwanga ngenkathi ushintsha inethiwekhi, futhi ugcine amanothi ngalokho okushintshile.

Uma umqhubi eshintshe indawo yokugcina muva nje, cela imininingwane yamanje esikhundleni sokuyakha kabusha emoyeni. Ikheli elingasekho likhiqiza kahle lolu hlobo lokwehluleka.

Bhala iphrothokholi, amanethiwekhi ahloliwe kanye nombono wengemuva. Lezi zintathu zixazulula imibiko eminingi ye-809.
