Dotaz: Bind9 pomoc

[georgee]

Prosim o radu, uz asi tyden se snazim rozvhodit DNS server v siti. Pouzivam na to Bind9. Nejaky fora jsem prolezl a pouzil nejaky konfiguraky. Tady je log pri spusteni bindu:

Vždyť ti píše, kde je problém:

Tak začni opravovat...

[georgee]

Vim ze to pise, kde a najem radku, ale nevim proc to pise jaka je tam chyba. Nevim jestli neco treba prehlizim. Proto se ptam.

[ZAH]

Řekl by, že na konci named.conf přebývá }; , a nejen tam.

[georgee]

Tak jsem to trochu upravil.

Ale ted je tam chyb mene v logu ale stejne porad jsou.

Uz nevim, mozna je tam nekde neco navic nebo tam neco chyby a jaksi na to nemuzu prijit.

[ZAH]

Neupravuj trochu, ale úplně opravuj. Chybu máš na řádce 46 view a na konci. Osobně si myslím že problém je na řádce 46(view) vyhoď ji celou a uvidíš. Každopádně neuzavřené závorky.

[Michal]

A nemas nahodou chybu v /etc/bind/named.conf.options ? Nevim jak bind parsuje konfiguraky, ale dost mozna ten externi soubor proste vlepi na misto kde je include a pokud v tom vlozenem souboru je nejaka chyba tak ta se pak muze trochu nelogicky projevit az pri parsovani hlavniho souboru.

Pak tam taky mas dost neuzavrenych 'zone xyz' sekci. Vlastne skoro vsechny. Za skoro kazdym 'allow-query { any };' patri jeste jedna zaviraci zavorka a strednik na ukonceni zone.

Hele byt tebou bych zacal od minimalniho funkcniho konfiguraku (jedno view, jedna zona) a postupne to rozsiroval. Ne naopak - vycucat si z prstu megakonfigurak a pak v nem hledat chybu.

[Michal Kubeček]

Přesně tak. V tom includovaném souboru není ukončená sekce options, takže direktiva view v hlavním souboru je uvnitř ní a tam nemá co dělat.

Ptát se na radu ve fóru, když ten konfigurační soubor nemá ani vybalancované závorky, mi připadá poněkud nevkusné (zvláště když na to démon výslovně upozornil).
