Ezinsukwini ezimbalwa ezedlule i-consortium I-ISC ikhiphe iseva yeKea 1.6.0 DHCP, esikhundleni se-DHCP ISC yakudala. Iseva ye-DHCP I-Kea isuselwe kubuchwepheshe be-BIND 10 futhi yakhiwe kusetshenziswa ukwakheka kwe-modular, okusho ukuwohloka kokusebenza kuzinqubo ezahlukahlukene zokulawula.
Umkhiqizo uhlanganisa ukusebenza kweseva okusebenza ngokugcwele ngokusekelwa kwezivumelwano ze-DHCPv4 ne-DHCPv6, engangena esikhundleni se-DHCP ye-ISC. I-Kea inamathuluzi akhelwe ngaphakathi eDynamic DNS Zone Update, isekela izindlela zokuthola amaseva, ukwabela amakheli, ukuvuselela nokuxhuma kabusha, izicelo zensizakalo zolwazi, ukugcina amakheli wababungazi, nokulanda kwe-PXE.
Ukuqaliswa kwe-DHCPv6 futhi kunikeza inketho yokudlulisa iziqalo. I-API ekhethekile inikezwa ukusebenzisana nezinhlelo zokusebenza zangaphandle. Kungenzeka ubuyekeze ukumiswa endizeni ngaphandle kokuqalisa kabusha iseva.
Imininingwane emayelana namakheli abelwe kanye nemingcele yamakhasimende ingagcinwa ezinhlotsheni ezahlukahlukene zokugcina izitoko; okwamanje okwenziwe emuva kunikezwa ukugcina amafayela we-CSV, i-MySQL, i-Apache Cassandra, ne-PostgreSQL.
Imingcele yokubamba yokusingathwa ingacaciswa kufayela lokumiswa ngefomethi ye-JSON noma njengetafula ku-MySQL ne-PostgreSQL. Kufaka ithuluzi le-perfdhcp ukukala ukusebenza kweseva ye-DHCP nezakhi zokuqoqa izibalo.
I-Kea ikhombisa ukusebenza okuhle, ngokwesibonelo, lapho usebenzisa i-MySQL backend, iseva ingenza ukwabiwa kwamakheli ayi-1000 ngomzuzwana (cishe amaphakethe angama-4000 ngomzuzwana), futhi lapho usebenzisa i-memfile backend, ukungena kufinyelela kuzabelo ezingama-7500 ngomzuzwana.
Yini okusha in Kea 1.6
Kule nguqulo entsha yeKea onjiniyela bagqamisa esimemezelweni sabo ukuqaliswa kwe-backend yokulungiselela evumela ukuphatha ngaphakathi ukumiswa kwamaseva we-DHCPv4 ne-DHCPv6.
Isiphetho sangemuva ingasetshenziselwa ukugcina izilungiselelo eziningi ze-Kea, kufaka phakathi izilungiselelo zomhlaba wonke, imininingwane emayelana namanethiwekhi abiwe, ama-subnet, izinketho, amaqembu nezincazelo zezinketho.
Esikhundleni sokugcina zonke lezi zilungiselelo kufayela lokumiswa lasendaweni, manje sezingafakwa ku-database yangaphandle.
Ngasikhathi sinye, kungenzeka ukunquma hhayi nge-CB yonke, kepha ingxenye yokulungiselela enezipharamitha ezigqagqene ezivela kudathabheyisi yangaphandle kanye namafayela wokumiswa kwasendaweni (ngokwesibonelo, ukumiswa kokuhlangana kwenethiwekhi kungashiywa kumafayela endawo).
Kusuka ku-DBMS, yi-MySQL kuphela okwamanje esekelwayo ukugcina ukucushwa (I-MySQL, i-PostgreSQL, ne-Cassandra ingasetshenziselwa ukugcina izisekelo zokwabiwa kwamakheli (izivumelwano zokuqashisa), futhi i-MySQL ne-PostgreSQL kungasetshenziswa ukubamba izingosi.)
Ukucushwa ku-database kungaguqulwa kokubili ngokufinyelela okuqondile kwi-DBMS nangemitapo yolwazi esezingeni eliphakathi nendawo elungiselelwe ngokukhethekile enikezela isethi ejwayelekile yemiyalo yokuphathwa kokumiswa, njengokungeza nokususa amapharamitha, izixhumanisi, i-DHCP kanye nezinketho ze-subnet.
Kungezwe isigaba esisha sabalawuli be-DROP (wonke amaphakethe ahambisana nesigaba se-DROP alahlwa ngokushesha), angasetshenziswa ukususa ithrafikhi engafuneki, ngokwesibonelo, izinhlobo ezithile zemiyalezo ye-DHCP.
Kwengezwe nemingcele emisha isikhathi sokuqashisa kakhulu nesikhathi sokuqasha, ezenza ukuthi kutholakale isikhathi sokusebenziseka kwesixhumanisi sokuqondisa sekhasimende (sokuqashisa) hhayi ngesilinganiso senani elinqunyiwe, kodwa ebangeni elamukelekayo.
Kanye nokuhambisana kuthuthukisiwe ngamadivayisi angahambisani ngokuphelele nezindinganiso ze-DHCP.
Ukugwema izinkinga, UKea manje uthumela imininingwane ngohlobo lomlayezo we-DHCPv4 Ekuqaleni kohlu lwezinketho, icubungula izethulo ezahlukahlukene zamagama aphethe, ibona ukudluliswa kwegama lesikhungo esingenalutho, futhi ikuvumela ukuthi uchaze izinketho ngamakhodi 0-255.
Landa bese ufaka iKea 1.6
Ekugcineni, uma ufuna ukwazi okwengeziwe ngale seva ye-DHCP, kanye nokufakwa kwayo nokuphathwa kwayo, ungabheka imibhalo okucaciswe kahle kakhulu Kulesi sixhumanisi esilandelayo.
