file named.conf

acl mynet {
192.168.2.0/24;
};

options {
directory "/var/named";
notify yes;
auth-nxdomain yes;
// multiple-cnames yes;
listen-on {
192.168.2.253;
};
// forward first;
// forwarders {203.162.4.1;};
};

zone "vn.local" {
type slave;
file "2vn.local.zone";
masters {192.168.2.253;};

};
zone "2.168.192.in-addr.arpa" {

type slave;
file "22.168.192.in-addr.arpa.zone";
masters {192.168.2.253;};
};

Vậy bây giờ mình phải làm sao để slave dc

đã fix:
thêm slaves/ vào path trên là chạy dc slave

chào bạn ,

IP server của bạn là bao nhiêu , IP client là bao nhiêu ?

[tuanvu_n]

hi, anh Hậu. Em cấp phát ip như thề này, IP server thì 192.168.2.253

ddns-update-style interim;
ignore client-updates;

subnet 192.168.2.0 netmask 255.255.255.0 {

# --- default gateway
option routers 192.168.2.253;
option subnet-mask 255.255.255.0;

option domain-name "vn.local";
option domain-name-servers 192.168.2.253;

option time-offset -18000; # Eastern Standard Time
# option ntp-servers 192.168.1.1;
# option netbios-name-servers 192.168.1.1;
# --- Selects point-to-point node (default is hybrid). Don't change this unless
# -- you understand Netbios very well
# option netbios-node-type 2;

range dynamic-bootp 192.168.2.100 192.168.2.150;
default-lease-time 21600;
max-lease-time 43200;


# we want the nameserver to appear at a fixed address
host ns {
next-server marvin.redhat.com;
hardware ethernet 00:0C:29:C6:99:04;
fixed-address 192.168.2.254;
}
}

nói chung là dhcp va dns ổn, nhưng slave thì chưa được.

ah, cuối cùng em đã làm được(thêm slaves\), thanks anh đã reply.
ah cho em hỏi thông số notify nó có mục đíc gì vậy? em coi một số file sample và chút tài liệu thì không thấy notify

chào bạn ,

Bạn dịch chữ notify có nghĩa là gì ?

"DNS NOTIFY works like this: when a primary master name server notices a change to data in a zone, it sends a special request to all of the slave servers for that zone. It determines which servers are the slaves for the zone by looking at the list of NS records in the zone and taking out the one that points to the name server listed in the first record-specific field in the zone's SOA record as well as the local host."
