BIND9 DNS SERVER - Muitas consultas com falha com referências SERVFAIL e EDNS

0

Estou executando meu próprio servidor BIND9 que está sendo executado em um arch linux na minha rede local. Desde a execução do servidor comecei a receber vários erros no meu navegador (chrome no android 6). Esses erros geralmente aparecem todos de uma vez em seguida:

  • dns sonda mal
  • err_name_not_resolved
  • err_timed_out ( Atualizar IV )

O problema é resolvido após cerca de 30 segundos, bastando clicar na mensagem de erro para tentar recarregar a página. Meus logs não estão exibindo entradas suspeitas (journalctl -r -u named). Eu postei minha configuração bind9 junto com as zonas relevantes / em execução abaixo. Há algum problema óbvio que alguém poderia apontar? Fico feliz em produzir mais arquivos de configuração / log conforme necessário ou executar qualquer teste. Eu deveria também mencionar que eu configurei um servidor dhcp na mesma máquina. Essa caixa, além disso, também está hospedando um convidado do windows server 2016 com libvirt em kvm com um hipervisor qemu. Eu tenho a saída de addip addr showˋ anexada abaixo.

Atualizar I: Depois de verificar novamente o log do meu servidor de DNS, há, na verdade, várias consultas com falha. Analisando agora. Log é anexado na parte inferior. Grato por qualquer ponteiros. Obrigado! (não um administrador de sistemas por dia, em vez de um desenvolvedor de software, então este não é realmente meu domínio de especialização, por assim dizer)

Atualização II: Possivelmente resolvi meu problema definindo explicitamente o endereço para ouvir. Nesse caso: listen-on { 192.168.1.35; }; (em /etc/named.conf ). Monitorará o registro e, finalmente, confirmará nas próximas 24 horas.

Atualização III: Ainda recebendo servfail erros no meu log do servidor dns, mas explicitamente configurando o endereço IP para escutar Eu ainda não recebi nenhum erro no meu navegador neste dispositivo e também sinto que o desempenho da consulta aumentou. O último, claro, é altamente subjetivo. O erro servfail aponta para um arquivo C query.c na linha 8298. Eu também estou olhando para o parâmetro bind9 edns-udp-size em conexão com o meu modem roteador / internet. Uma vez eu exibi um Telekom Speedport W920V em um VDSL FritzBox 7570 da AVM que ainda uso como meu modem / roteador vDSL. Ainda muito esperando por alguns ponteiros. Felicidades.

Atualização IV: Adicionado erro adicional do navegador, conforme descrito acima. Além disso, como mencionado em UIII, estou analisando o parâmetro EDNS-UDP-SIZE devido às seguintes entradas de log:

Feb 07 19:05:01 nas named[10928]: success resolving 'clients4.google.com/A' (in '.'?) after reducing the advertised EDNS UDP packet size to 512 octets
Feb 07 19:04:54 nas named[10928]: client @0x7f7a18204640 192.168.1.31#14927 (clients4.google.com): query: clients4.google.com IN A + (192.168.1.35)

A questão é positivamente corrigida. Eu criei um repositório github onde adicionei todos os arquivos de configuração nomeados relevantes, bem como registros para comparação entre o repositório quebrado e trabalhando versões de configuração do meu servidor nomeado. Em última análise, não posso realmente identificar o problema, mas eu poderia ter sido um erro de configuração de minhas zonas de frente e reversa. Na minha zona de frente onde declarar o registro NS eu adicionei o domínio como assim

muncic.local.  NS  IN  nas.muncic.local.

em vez de

NS  IN  nas.muncic.local.

Na minha zona reversa, avistei um registro PTR que não estava usando o valor correto

35                     IN   PTR 35.0.1.168.192.muncic.local.

em vez de

35                     IN   PTR nas

Eu também fiz várias alterações na minha ligação named.conf nomeada para a minha segunda interface com fio enp6s0 rodando em 192.168.1.33.

Esta foi a minha saída journalctl para o nome antes e depois da correção por aproximadamente 24 horas cada:

$ journalctl -u named --since="2017-02-12" --until="2017-02-13" | grep  SERVFAIL -c
67
$ journalctl -u named --since="2017-02-14" | grep  SERVFAIL -c
