I-DMZ host ku-router noma ukufinyelela okuyimfihlo: yikuphi okufanele i-Mac?

Isilungiselelo se-DMZ host ku-router yasekhaya sizwakala njengendawo yokuphepha kodwa sisebenza njengokudlulisela konke. Konke okufika kusuka ku-inthanethi okungafani nanoma yimuphi omunye umthetho kuthunyelwa ekhelini le-LAN elikhethiwe. Lona wukushorcut ukuze isevisi engenayo isebenze, hhayi umklamo wokufinyelela kuyi-Mac eyodwa ngasese. Yiqhathanise nomthetho omncane noma indlela eyimfihlo ngaphambi kokuyivula.

Isilungiselelo se-DMZ senza ini ngempela

Kumafirmware amaningi abasebenzisi lelebula isho into eyodwa ngqo: ithrafikhi engenayo engafani idluliselwa ku-host eqokiwe. Ayidali i-subnet ehlukile, indawo yodonga lomlilo noma umngcele wokwehlukanisa. Ikhompyutha ekhethiwe ithola konke i-router engakwazi ukuthi ikwenze ini.

Yingakho isilungiselelo sisebenza kahle kakhulu ekulungiseni isevisi ephukile futhi sibuthakathaka kakhulu ekukhawuleni okunye okufikayo. I-router yenza okushiwo kuyo, ngokubanzi. Akukho lutho ku-firmware oluhlukanisa isicelo obusisifuna kwesingasifunanga.

Izindima ezintathu ze-Mac, iminyango emithathu yangaphambili

Bhala uhlu lwalokho i-Mac ekwenzayo ngempela ngaphambi kokuvula noma yini. Iklayenti elishaya ngaphandle alidingi noma yimuphi umthetho ongenayo. Iseva idinga isilaleli sayo, ukuqinisekisa kwayo kanye nokuthutha okuncane. Ithagethi yokwabelana ngesikrini idinga indlela eyimfihlo kanye nohlu lwabasebenzisi abavunyelwe besevisi. Lezi izimiso ezintathu ezihlukene, futhi isilungiselelo se-DMZ asifaneli kahle neyodwa yazo.

sudo lsof -nP -iTCP -sTCP:LISTEN

Gijimisa lokho ku-Mac bese ufunda uhlu. Uma kungekho okulalelayo, awukho umthetho ongenayo ozokwenza isevisi ivele.

Qhathanisa ukuchayeka, hhayi ukunethezeka

Ukudlulisela konke kwandisa indawo yokuhlasela kuyo yonke imbobo i-Mac eyidalulayo, kufaka phakathi izevisi okhohlwe ukuthi zivuliwe. Ukudlulisela okuncane kudaluza imbobo eyodwa ku-inthanethi futhi kusadinga ukuqinisekisa kohlelo ngokwalo. Indlela eyimfihlo ayidaluli lutho esidlangalaleni, ngezindleko zokudinga umhubhe ngaphambi kokufinyelela.

Ukunethezeka akusona isinqumo lapha, ngoba inketho elula iyona futhi ehluleka ngokuvulekile. Uma i-Mac ixhuma ngaphandle kuphela, inani elifanele lezikhala ezingenayo liwuziro, futhi lowo musho ufanele ufunde kabili ngaphambi kokuvula imbobo. Ukukhetha okunye kusho ukwamukela ukuchayeka ongakudingi. Bhala phansi lokho kuchayeka futhi ukukhetha ngokuvamile kuzixazulula ngokwako.

Shintsha ukudlulisela konke ngaphandle kokuphazamiseka

Ukushintsha ukudlulisela konke kuwumsebenzi wokubala impahla ngaphambi kokuba kube ushintsho lodonga lomlilo. Thola ukuthi iyiphi isevisi esemthethweni encike kumthetho obanzi njengamanje, futhi uqinisekise ukuthi okushintshayo kuyasebenza kuyo ngayinye. Bese ususa umbhalo we-DMZ futhi wengeze kuphela umthetho omncane noma ukufinyelela okuyimfihlo okudingwa umklamo. Ukushiya yomibili iminyango ivulekile ngesikhathi sokushintsha yikho okwenza isisombululo sesikhashana sibe ngokunaphakade.

Gcina udonga lomlilo lwe-host kanye nokuqinisekisa kwesevisi ngokwayo endaweni yakho kungakhathaliseki indlela. Umhubhe uvikela ukuthutha, hhayi isilaleli esidlangalaleni esihlezi ngengozi emshinini ofanayo. Ukulungiswa nokubuyekezwa kusanquma ukuthi isevisi iphephile yini, futhi ukubuyekezwa kwe-firmware kungashintsha buthule okungeniswa umthetho obanzi. Imibhalo yomkhiqizi ye-similo se-DMZ host isho okufanayo ngokuchayeka, ngamagama ambalwa.
