Bind: Carane nyeting NS 1 karo NS 2 sing kanggo backup neng OpenSuSE 11

>> Mukodimah <<

Poro pamiyarso sakwijining dino ono bocah sing jenenge DNS (Domain Name System) sing gaweane kuwi nerjemahke alamat IP neng Domain utawa walikane. Iso diumpamakke koyo phonebook nenggone hape. Lha umpamane awake ndewe kon ngeling-eling kabeh entry neng phonebook mau dalam bentuk nomer kan yo iso ra doyan mangan pitung dino pitung wengi tho??, Lha mangkane digawe contact sing isine jeneng karo nomer lan liyoliyane,ben mayar tur ora ngelu sirahe.

Salah sijine aplikasi sing kanggo nggawe DNS mau jenenge BIND. Ono ing tutorial ngisor iki aku nganggo OS OpenSuSE 11.

Kaping sepisan yo kuwi kudu nginstall BIND ndisik nganggo command ing ngisor iki:
adam:~ # YaST2 -i bind*

Sakwise kuwi banjur ngedit file-file konfigurasi neng ngisor iki:

############################
#### /etc/resolv.conf ######
############################
nameserver 208.99.198.188
nameserver 208.99.198.180 ##>>> nameserver nomer loro iki ditambahke neng konfigurasi ono ing server nomer 2

****catatan penting : intine update dari ns 1 ke ns 2 yo kuwi nomer serial ing konfigurasi neng nduwur iki, dadi nek meh ng-update kudu ngudakke serial neng ns siji ben iso luwih dhuwur ketimbang ns 2,so iso update okeh???

####################################################################
command neng ngisor iki dijalanke neng ns 2 so ns 1 ne iso overwrite ke ns dua gt lohh
