Korzystam z własnego serwera BIND9, który działa na arch. Linuksie w mojej sieci lokalnej. Od uruchomienia serwera zacząłem otrzymywać różne błędy w przeglądarce (Chrome na Androidzie 6). Błędy te pojawiają się zwykle naraz:
- dns probe bad
- err_name_not_resolved
- err_timed_out ( aktualizacja IV )
Problem rozwiązuje się po około 30 sekundach, po prostu klikając komunikat o błędzie podczas próby ponownego załadowania strony. Moje dzienniki nie zawierają żadnych podejrzanych wpisów (Journalctl -r -u o nazwie). Wysłałem moją konfigurację bind9 wraz z odpowiednimi / działającymi strefami poniżej. Czy są jakieś oczywiste problemy, na które ktoś mógłby zwrócić uwagę? Z przyjemnością tworzę więcej plików konfiguracyjnych / logów zgodnie z wymaganiami lub przeprowadzam testy. Powinienem też wspomnieć, że mam skonfigurowany serwer DHCP na tym samym komputerze. To pudełko dodatkowo obsługuje gościa Windows Server 2016 z libvirt w kvm z hiperwizorem qemu. Mam wynik belowip addr showˋ załączony poniżej.
Aktualizacja I: Po ponownym sprawdzeniu dziennika serwera dns, w rzeczywistości istnieje wiele nieudanych zapytań. Analizuję teraz. Dziennik jest dołączony na samym dole. Wdzięczny za wszelkie wskazówki. Dzięki! (z dnia na dzień nie administratorem systemu, a nie programistą, więc tak naprawdę to nie moja dziedzina wiedzy specjalistycznej)
Aktualizacja II: Możliwe, że rozwiązałem mój problem, jawnie ustawiając adres, na którym chcesz nasłuchiwać. W takim przypadku: listen-on { 192.168.1.35; };
(in /etc/named.conf
). Będzie monitorować dziennik i ostatecznie potwierdzić w ciągu następnych 24 godzin.
Aktualizacja III: Nadal otrzymuję servfail
błędy w moim dzienniku serwera dns, ale ponieważ jawnie ustawiam adres IP do nasłuchiwania, nie otrzymałem jeszcze żadnych błędów w mojej przeglądarce na tym urządzeniu i czuję, że wydajność zapytania wzrosła. To ostatnie jest oczywiście bardzo subiektywne. Te servfail
punkty błędów do pliku C query.c
na linii 8298. Ja również poszukuje do parametru bind9 edns-udp-size
w związku z mojego modemu routera / Internetu. Raz sflashowałem Telekom Speedport W920V do AVM FritzBox 7570 vDSL, którego nadal używam jako mojego modemu / routera vDSL. Nadal bardzo liczę na pewne wskazówki. Twoje zdrowie.
Aktualizacja IV: Dodano dodatkowy błąd przeglądarki, jak wyżej. Również, jak wspomniano w UIII, szukam parametru EDNS-UDP-SIZE
ze względu na następujące wpisy dziennika:
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

servfail
błędy w moim dzienniku serwera dns, ale ponieważ jawnie ustawiam adres IP do nasłuchiwania, nie otrzymałem jeszcze żadnych błędów w mojej przeglądarce na tym urządzeniu i czuję też, że wydajność zapytania wzrosła. To ostatnie jest oczywiście bardzo subiektywne. Te servfail
punkty błędów do pliku C query.c
na linii 8298. Ja również poszukuje do parametru bind9 edns-udp-size
w związku z mojego modemu routera / Internetu. Raz sflashowałem Telekom Speedport W920V do AVM FritzBox 7570 vDSL, którego nadal używam jako mojego modemu / routera vDSL. Nadal bardzo liczę na pewne wskazówki. Twoje zdrowie.
resolv.conf
. Zauważyłem też w mojej strefie przekazywania w mojej deklaracji NS, że zacząłem muncic.local
zamiast całkowicie ją pomijać. Dalej w mojej strefie odwróconej brakowało mi, aby zadeklarować rekord PTR dla mojego serwera dns ( 35 PTR {..}
). To tylko kilka moich zmian. Żeby być dokładnym, pracowałem nad plikiem dhcpd.conf nad zbyt jego czyszczeniem. Jak dotąd brak nieudanych zapytań. W przypadku, gdy będzie to miało miejsce przez następne 24 godziny, opublikuję moje zmiany, wskazując, co najprawdopodobniej było nie tak.
listen-on { 192.168.1.35; };
. Będzie monitorować dziennik i ostatecznie potwierdzić w ciągu następnych 24 godzin.
