I-NFS phezu kwe-TCP ngaphakathi komhubhe we-UDP we-OpenVPN: izindlela ezimbili zokuthutha

Ukuthutha ingxoxo ye-NFS esebenzisa i-TCP ngaphakathi komhubhe othwala i-UDP kuvumelana ngokuphelele, futhi kudida abantu ngoba kusho izindlela ezimbili zokuthutha ngesikhathi esisodwa. I-TCP ingxoxo yesevisi yamafayela phakathi kweklayenti neseva ye-NFS. I-UDP isithwali esibethelwe phakathi kweziphetho ze-VPN. Akukho kokubili okusho okuthile ngomunye.

Bhala kokubili ngokwehlukana ngaphambi kokuxazulula noma yini; iningi lezehlakalo lezi liqala lapho othile eshintsha isendlalelo esingalungile.

Izendlalelo ezimbili, izilungiselelo ezimbili

Inketho yokukhweza proto=tcp ichaza ukuthi iklayenti le-NFS likhuluma kanjani neseva ye-NFS. Isilungiselelo proto udp kuphrofayela ye-VPN sichaza ukuthi iziphetho zomhubhe zishintshana kanjani ngamaphakethe afakwe embozini. Ukushintsha inketho yokukhweza akushintshi umhubhe, futhi ukushintsha ukuthutha komhubhe akushintshi lokho iklayenti le-NFS elivumelene ngakho. Qinisekisa izinketho zokukhweza ezisebenzayo nge-nfsstat -m esikhundleni somugqa we-fstab, futhi uqinisekise ukuthutha kwe-VPN kuphrofayela esetshenziswa ngempela.

Bese ubhala kokubili kumanothi esehlakalo njengezinkambu ezimbili ezihlukene. Ukuthuthuka okubonakalayo kungalandelelwa kuphela uma inothi lisho ukuthi yisiphi isendlalelo esishintshile.

Ukuphequlula akukona ukufunda okukhulu

Uhlu lwedayirekhithi lubonisa ukuthi eminye imisebenzi yaqedwa. Alubonisi ukuthi ukufunda okuqhubekayo, ukubhala, ukukhiya noma ingemuva lesitoreji kuzoqedwa ngaphansi kwezimo ezifanayo. Ukuma phakathi nefayela elikhulu kuwumbono ohlukile kunokukhweza okungaphumeleli neze, futhi kukhombisa izendlalelo ezihlukene.

Chaza ngokunemba umsebenzi ohlulekayo: indlela, isiqondiso, indawo elinganiselwe yokuma, kanye nomcimbi wokugcina ofanele emarekhodini eklayenti, eseva ne-VPN. Bese uqhathanisa lapho ithrafikhi iqhubeka khona nalapho ima khona.

I-MTU iwumbono nje, akuwona umuthi wokuxilonga

Ukulahleka okuncike kusayizi wephakethe kungenzeka ngempela lapho umhubhe uthwala izingxenye ezinkulu, futhi kukhiqiza ngqo iphethini yokuthi ukuphequlula kuyasebenza kodwa ukufunda kuyama. Nokho leyo phethini ayibonisi inkinga ye-MTU, ngoba isimo esifanayo sivela lapho iseva inensayo, lapho udonga lomlilo lunqamula uxhumano olude ngenxa yesikhathi sokuphela, noma lapho idiski imatasa. Hlola umbono ngocwaningo olulawulwayo esikhundleni sokwehlisa i-MTU yonke indawo bese umemezela ukunqoba.

Isikhathi sokuphela sisodwa asisho lutho mayelana nokuthi i-UDP kufanele ishintshwe yini. Kuwuphawu olunabanikazi abaningi abangaba khona.

Shintsha into eyodwa ngesikhathi

Uma uqhathanisa izindlela zokuthutha, gcina umthwalo we-NFS nayo yonke eminye izilungiselelo uzinzile. Ukushintsha ukuthutha kokukhweza, iphrothokholi yomhubhe kanye ne-MTU efasiteleni elifanayo lokulungisa kuveza umphumela okungekho muntu ongawunikeza umsuka. Gijimisa umsebenzi ofanayo wefayela ngaphambi nangemva, futhi urekhode umphumela esigabeni ngasinye.

Gcina namagugu angaphambili kuthikithi. Uma ushintsho lwenza izinto zibe zimbi kakhulu, ukuhlehla kufanele kube yinombolo ebhaliwe, hhayi inkumbulo yomuntu yokuthi kwakunjani ngaphambili.

Funda isendlalelo esihlulekile

Uma umhubhe uphilile futhi isicelo se-NFS silindile, i-VPN ayihlulekanga; isevisi yamafayela ihlulekile. Uma umhubhe wehla, ukuhluleka kwesicelo se-NFS kuwumphumela hhayi imbangela. Ukuqhathanisa imigqa yamarekhodi evela kuzo zombili izendlalelo kuyindlela eshesha kakhulu yokuhlukanisa lezi zimo ezimbili, futhi ingcono kunokuqagela kusuka kumphathi wamafayela.

Bhala isiphetho njengemisho emibili, eyodwa esendlalelweni ngasinye. Lokho kwanele ukuthi umuntu olandelayo aphinde ukuhlola ngaphandle kokuphinda athole ukuthi yikuphi ukuthutha okukuyiphi.
