DHCP dan DNS

ipoelnet

Ini OM, oh iya;

**nobody dnsmasq 515 3 udp4 :53 :
nobody dnsmasq 515 4 tcp4 :53 :

Terus Gmn OM?
di list data g' ada file dan folder /etc/namedb/named.conf

Apa saja yang di setting OM?
isi dari /etc/namedb/named.conf tersebut apa n permissionnya?
dan juga untuk mematikan dnsmasq agar bind saja yg berjalan?

Saya tunggu Om, hm… sekarang Q mau masuk kelas dulu,.,.,

grage95

kalo gak ada, coba di cari dengan command find /|grep named.conf
dnsmasq cukup responsif jika digunakan utk net kecil, namun jika utk network besar, dnsmasq sering bengong, walopun sudah dinaikkan cache-size s/d 256Mb. jika di hajar client banyak tiba2 akan muncul warning dns attack !!!!, solusinya gunakan bind, tambahkan option di named.conf cache-data-size dan max-cache-size cukup di buat 8-64 Mb sudah maknyuss

agak ribet menjalankan bind di pfsense, ada beberap script tambahan agar bind/named bisa running seteleh di reboot,
langkah2nya panjang, konsepnya seperti ini :
1.buat dnsmasq.conf di /usr/local/etc/dnsmasq.conf dan option utk mengkatifkan dns jangan di pake, hanya gunakan option utk mengkatifkan dhcp server saja, silahkan try to google tentang dnsmasq
2. buat script rc.conf utk mengaktifkan bind, silahkan try to google tentang bind/named utk freebsd

ipoelnet

Hmmmm,,, gagal lagi… gagal lagi...
Malah jadi error nich...
Restor factory default.............
tolongin dong Om grage...
pakai bind-nya...
Q udah nyontoh http://www.freebsd.org/doc/en/books/handbook/network-dns.html tapi malah tambah ngeluh....

Q bind-nya ganti pakai http://files.pfsense.org/packages/dns/bind9-9.3.2.1.tbz ribet...

heheh versi library crypt gak cocok dengan named
coba cek libraray crypto yang ada versi berapa ?

ls /lib/libcypt*
di buat link

cd /lib
ln -s libcrypt.so.5 libcrypt.so.4
ln -s libcrypto.so.6 libcrypto.so.5

hmm sudah ada tapi tdk di kenali sama named

kayanya bind yang ada versi jadul (freebsd 7)
pfsense1-2.3 menggunakan versi freebsd7.2

coba install ulang bindnya dari sini

pkg_delet bind\*
pkg_add -rv http://dl2.foss-id.web.id/freebsd/ports/i386/packages-7.2-release/dns/bind96-9.6.0.1.tbz
rehash

berarti tinggal named nya
coba di log messages nya

tail -f /var/log/messages ada yang aneh enggak

config named.conf gunakan yg seperti contoh yang aku kasih

taruh di /var/named/etc/namedb/named.conf

cek dengan sockstat dan ps -ax
