DNS Server di Slackware

1. 1. Konfigurasi DNS Server
   1. a. Pemasangan IP Address

Cek ethernet

root@plnsbam:~# ifconfig root@plnsbam:~# ifconfig eth0 up

Isi Ip address

root@plnsbam:~# nano /etc/rc.d/rc.inet1.conf # Config information for eth0: IPADDR[0]=”202.45.67.13” NETMASK[0]=”255.255.255.192” # Config information for eth1: IPADDR[0]=”" NETMASK[0]=”" # Default gateway IP address: GATEWAY=”202.45.67.13″

Restart Ethernet

root@plnsbam:~# /etc/rc.d/rc.inet1 restart

1. b. Konfigurasi bind

Cek paket bind

root@plnsbam:/#ls /var/log/packages/ | grep bind bind-9.4.3_P2-i486-2 kdebindings-4.2.4-i486-1 /var/named/caching-example/named.ca /var/named/caching-example/named.local /var/named/caching-example/localhost.zone /etc/rc.d/rc.bind /etc/named.conf

Pindahin file bind naik satu level directory

mv /var/named/caching-example/* /var/named/ root@bukitasam:~# ls /var/named /var/named/named.ca /var/named/named.local /var/named/localhost.zone /var/named/caching-example

Edit file named.conf tambahin baris ini

zone "plnsbam.com" IN { type master; file "/var/named/plnsbam.zone"; allow-update { none; }; }; zone "67.45.202.in-addr.arpa" IN { type master; file "/var/named/202.45.67.zone"; allow-update { none; }; };

Copykan beberapa file named menjadi zone/db dari domain dan ip

root@plnsbam:~# cd /var/named root@plnsbam:~# cp localhost.zone plnsbam.zone root@plnsbam:~# cp named.local 202.45.67.zone root@plnsbam:~# ls caching-example named.ca named.local localhost.zone plnsbam.zone 202.45.67.zone

Edit file zone dari domain ubah baris perintah seperti ini

root@plnsbam:~# nano /var/named/plnsbam.zone $TTL 86400 $ORIGIN plnsbam.com. @ IN SOA ns.plnsbam.com root.plnsbam.com ( 42 ; serial (d. adams) 3H ; refresh 15M ; retry 1W ; expiry 1D ); minimum @ IN NS ns.plnsbam.com. @ IN A 202.45.67.13 ns.plnsbam.com. IN A 202.45.67.13 www.plnsbam.com. IN A 202.45.67.13 mx.plnsbam.com. IN A 202.45.67.10 mta1.plnsbam.com. IN CNAME mail.plnsbam.com. mail.plnsbam.com. IN CNAME mx.plnsbam.com. plnsbam.com. IN MX 10 mail.plnsbam.com.

Ctt:

mx.plnsbam.com. = mx = mail exchange

mta1.plnsbam.com. IN CNAME mail.plnsbam.com. = mengalihkan nama mta1.plnsbam.com ke mail.plnsbam.com

mail.plnsbam.com. IN CNAME mx.plnsbam.com. = mengartikan bahwa mail.plnsbam.com = mx.plnsbam.com

plnsbam.com. IN MX 10 mail.plnsbam.com. = MX-nya = 10 = lama waktu untuk akses relay ke mail.plnsbam.com.

edit file ip.zone

root@plnsbam:~# nano /var/named/202.45.67.zone $TTL 86400 @ IN SOA ns.plnsbam.com. root.plnsbam.com. ( 1997022700 ; Serial 28800 ; Refresh 14400 ; Retry 3600000 ; Expire 86400 ) ; Minimum @ IN NS plnsbam.com. 13 IN PTR www.plnsbam.com. 10 IN PTR mx.plnsbam.com.

Copy file RNDC-CONFGEN

root@plnsbam:~# rndc-confgen ………. key “rndc-key” { algorithm hmac-md5; secret “JNDHF4c7BY8xpzGsYoC3+Q==”; }; controls { inet 127.0.0.1 port 953 allow { 127.0.0.1; } keys { “rndc-key”; }; };

Copykan ke file ini.

root@plnsbam:~# cat rndc-confgen >> /etc/named.conf root@plnsbam:~# nano /etc/named.conf ………. key “rndc-key” { algorithm hmac-md5; secret “JNDHF4c7BY8xpzGsYoC3+Q==”; }; controls { inet 127.0.0.1 port 953 allow { 127.0.0.1; } keys { “rndc-key”; }; };

copy file rndc.key menjadi file rndc.conf

root@plnsbam:~# cp /etc/rndc.key /etc/rndc.conf

Copy rndc-confgen ke rndc.conf dan ambil baris ini

root@plnsbam:~# cat rndc-confgen >> /etc/rndc.conf options { default-key “rndc-key”; default-server 127.0.0.1; default-port 953; };

Sehingga script rndc.conf

key “rndc-key” { algorithm hmac-md5; secret “0z5PHh0vUDdeY75ZJgbnyg==”; }; options { default-key “rndc-key”; default-server 127.0.0.1; default-port 953; };

Ubah akses permission service bind dan jalankan

root@plnsbam:~# chmod +x /etc/rc.d/rc.bind root@plnsbam:~# /etc/rc.d/rc.bind start

Cek menggunakan perintah nslookup

root@plnsbam:~# nslookup > www.plnsbam.com Server: 202.45.67.13 Address: 202.45.67.13#53 Name: www.plnsbam.com Address: 202.45.67.13 > plnsbam.com Server: 202.45.67.13 Address: 202.45.67.13#53 Name: plnsbam.com Address: 202.45.67.13 > ns.plnsbam.com Server: 202.45.67.13 Address: 202.45.67.13#53 Name: ns.plnsbam.com Address: 202.45.67.13 > mx.plnsbam.com Server: 202.45.67.13 Address: 202.45.67.13#53 Name: mx.plnsbam.com Address: 202.45.67.10 > mta1.plnsbam.com Server: 202.45.67.13 Address: 202.45.67.13#53 mta1.plnsbam.com canonical name = mail.plnsbam.com. mail.plnsbam.com canonical name = mx.plnsbam.com.

Name: mx.plnsbam.com Address: 202.45.67.10 > 202.45.67.13 Server: 202.45.67.13 Address: 202.45.67.13#53 13.67.45.202.in-addr.arpa name = www.plnsbam.com. > 202.45.67.10 Server: 202.45.67.13 Address: 202.45.67.13#53 10.67.45.202.in-addr.arpa name = mx.plnsbam.com.
