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
