Izilungiselelo ze-punchy ze-Nebula: yikuphi okulungisa i-NAT yakho

Ama-peer amabili atholana ngombhoshongo wokukhanyisa bese ehluleka ukwakha indlela eqondile, futhi umgqigqo wokuqala ukuvula zonke izinketho ze-punchy. Lowo mgqigqo ukhiqiza ukucushwa okunezinguquko ezintathu ngaphandle kokwazi ukuthi yikuphi okubalulekile. Izilungiselelo ziphendula imibuzo ehlukene: esinye sigcina imephu esivele ikhona, kanti esinye sizama ukuxhawulana ngendlela ephambene. Nquma ukuthi umbuzo wakho uwuphi ngaphambi kokuthinta noma yikuphi kukho.

Qinisekisa iphoyinti lokugcina ngaphambi kwesikhathi

I-peer engaveli neze ekhelini elilindelekile ngeke isindiswe ukulungiswa kwe-punch. Bheka ukuthi umbhoshongo wazi ngani nge-peer nokuthi ukucushwa kwayo uqobo kumemezela ini, ngoba ikheli le-bootstrap elidala noma ikheli langasese elishicilelwe ngephutha kubhubhisa wonke amaqhinga okuwela. Qinisekisa futhi ukuthi isitifiketi sithenjwa, ngoba ubunikazi obungathenjwa bumisa ingxoxo kude ngaphambi kokuba i-NAT ibaluleke. Bese uqinisekisa ukuthi i-UDP ifinyelela umbhoshongo noma cha. Amanani esikhathi yinto yokugcina okufanele ibhekwe, hhayi eyokuqala.

Bhala phansi umbhangqwana wamaphoyinti okugcina owuhlolayo, ukuze iziqhathaniso zakamuva zisebenzise lawo ma-peer, hhayi eminye imishini emibili.

i-punch igcina imephu, i-respond ivula indlela

Inketho ye-punch ithumela amaphakethe angenalutho ngezikhathi ezithile ekhelini lesendlalelo se-peer esivele sinomhubhe. Inhloso yayo ayiyona into ekhazimulayo: ivimbela i-NAT enesimo noma i-firewall ekubeni ivumele imephu indlela eqondile encike kuyo ukuba iphelelwe yisikhathi. Inketho ye-respond ishintsha okwenzeka esazisweni sombhoshongo, yenza umsingathi azame ukuxhawulana abuyele emuva kuyo i-peer ezama ukufinyelela kuso. Lezi zindlela ezihlukene ezinendlela ezihlukene zokwehluleka.

Khetha i-punch lapho indlela eqondile isebenza bese iyancipha. Khetha i-respond lapho indlela ingakheki nakanye kolunye uhlangothi. Ukuvula kokubili nokuthemba yindlela yokuthi ukulungisa kwemizuzu emihlanu kube yiViki yokulungisa.

Ukubambezeleka kunquma ukuthi nini, hhayi ukuthi kuzokwenzeka yini

Amanani okubambezeleka asusa isikhathi: elinye lisebenza kumaphakethe athunyelwa ngemva kwesaziso, elinye emzamweni wokuxhawulana ophambene. Akukho okwenza indlela evinjelwe isebenze. Ukushintsha kokubili ngesikhathi esisodwa kubhubhisa isiqhathaniso obuzokwenza.

Ziyeke zibe njalo kuze kube yilapho indlela yokwenza ilungile. Bese ulungisa eyodwa, futhi ubhala phansi inani elidala.

Lapho i-relay iyimpendulo eqotho

Ezinye izinhlanganisela ze-NAT azikwazi ukusekela indlela eqondile, kungakhathaliseki ukuthi isikhathi sihlelwe kanjani. I-NAT elinganayo ezinhlangothini zombili, noma i-firewall elahla ngokuphelele ukuxhumana okungaceliwe okungena, akushiyi lutho lokubhoboza.

Inodi ye-relay enekheli elifinyelelekayo inika lawo ma-peer indlela enganciki empumelelweni yokuwela. Kukhonza ibhandiwidi ngokusebenzisa leyo nodi, ngakho isinqumo mayelana nomthamo hhayi indlela yokugwema. Lungiselela i-relay ngamabomu futhi uqinisekise ukuthi ama-peer ayifinyelela, ngoba i-relay eye yona ngokwayo ingemva kwe-NAT enzima ayishintshi lutho. Bese uyeka ukulungisa izilungiselelo ze-punch zalowo mbhangqwana, ngoba indlela eqondile yayingeke ivele.

Hlola umbhangqwana ohlulekile, ngemva kokungenzi lutho

Phinda ukhiqize isimo esaphuka: yeka umbhangqwana ungenzi lutho isikhathi esifanayo, noma phinda ukulandelana kokuxhawulana obekujwayele ukwehluleka. Bese usebenzisa uhlelo lokusebenza phakathi kwalawo ma-peer amabili, hhayi isicelo kumbhoshongo. Impendulo yombhoshongo ifakazela indlela yokulawula futhi ayisho lutho ngendlela yedatha.

Bhala phansi ukuthi yikuphi ukulungiselela okwashintsha, isikhathi, nokuthi indlela eqondile yavela noma ukuxhumana kwahlala ku-relay. Uma kwahlala, impendulo yi-relay kanye nenothi lomthamo, futhi lowo umphumela omuhle ngokuphelele. Uma yavela, umbuzo olandelayo ukuthi ingabe iyamela ihora lokungenzi lutho, ngoba imephu enciphayo iyinkinga uqobo i-punch ekhona ngayo.
