From: Timur Batyrshin <batyrshin@ieml.ru> To: ALT Linux sysadmin discuss <sysadmins@lists.altlinux.org> Subject: [Sysadmins] обновление DNS Date: Thu, 05 Apr 2007 20:10:19 +0400 Message-ID: <46151F6B.3010600@ieml.ru> (raw) 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.
