Объясните, пожалуйста, в чём разница между этими двумя наборами команд:
========
[root@server zone]# nsupdate -d
> key DHCP_UPDATER SECRET-KEY==
> server 127.0.0.1
> zone sub1.domain.ru
> update add test 3600 A 192.168.31.66
> send
Reply from update query:
;; ->>HEADER<<- opcode: UPDATE, status: NOTZONE, id: 5024
;; flags: qr ra ; ZONE: 0, PREREQ: 0, UPDATE: 0, ADDITIONAL: 1
;; TSIG PSEUDOSECTION:
=========
То же самое, но без директивы server :
=========
[root@server log]# nsupdate -d
> key DHCP_UPDATER SECRET-KEY==
> zone sub1.domain.ru
> update add test 3600 A 192.168.31.66
> send
; Communication with 127.0.0.1#53 failed: timed out
could not talk to any default name server
=========
Почему так? Ведь в обоих случаях запрос уходит на 127.0.0.1#53, а ответа в одном из них нет?
Вот на всякий случай настройки сервера:
/etc/resolv.conf:
search sub1.domain.ru
nameserver 127.0.0.1
/etc/HOSTNAME:
server
/var/lib/bind/etc/local.conf:
include "/etc/rfc1912.conf";
zone "sub1.ieml.ru" in {
type master;
file "sub1.ieml.ru.zone";
allow-update { key DHCP_UPDATER; };
};
zone "31.168.192.in-addr.arpa" in {
type master;
file "31.168.192.in-addr.arpa";
allow-update { key DHCP_UPDATER; };
};
key "DHCP_UPDATER" {
algorithm hmac-md5;
secret "ITmpAOsH0pwKmCJIM5LT2g==";
};
iptables отсутствует.
