14 How to Install ENUM Server? Instal DNS Server. Pada linux, biasanya sudah ada paket BIND yang merupakan DNS server yang dapat dioperasikan dengan mudah. Edit file /etc/named.conf untuk memberitahu sistem tentang letak data untuk domain yang kita buat. Edit file data ENUM untuk memasukkannomor telepon tiap pelanggan.

15 How to Install ENUM Server? Misal kita memperoleh alokasi nomor s.d Maka kita perlu mengedit file /etc/named.conf untuk domain e164.id dengan cara menambahkan entri : Zone ” e164.id” IN { type master; file ” e164.id.db”; allow-update { none; }; };

16 Semua data nomor telepon harus dimasukan ke file e164.id.db yang pada Fedora Core 5 terletak di /var/named/chroot/var/named/ e164.id.db. contoh isi file e164.id.db adalah sebagai berikut : $TTL SOA ns.warnet.co.id admin warnet.warnet.co.id. ( 42; serial (d. adams) 3H; refrerh 15M ; retry 1W : expiry 1D); minimum IN NS ns.warnet.co.id. 0.0NAPTR “u” “E2U+SIP” 1.0NAPTR “u” “E2U+SIP” 2.0NAPTR “u” “E2U+SIP” 7.8NAPTR “u” “E2U+SIP”
