Dotaz: bind po spusteni nenabehne

[slacki]

Nazdar all Pouzivam distro slackware 10 a chcem rozbehat DNS {bind} na servri.Postupoval som podla navodu na

http://deja-vix.sk/sysadmin/dns.html#top

Lenze ked dam spustit s parametrom

named -u named -t /var/named/etc/named.conf -t /var/named

tak vobec nenabehne.V logoch som nasiel hlasky typu

Aug 5 02:02:13 xxxx named[31098]: none:0: open: /var/named/etc/named.conf: file not found

Aug 5 02:02:13 xxxx named[31098]: loading configuration: file not found

Aug 5 02:02:13 xxxx named[31098]: exiting (due to fatal error)

lenze ten config tam je.

Ak niekto viete tak poradte

Nojo, to je uplne cele spatne. Asi vam moc neporadim, v Gentoo to je otazka nastaveni CHROOT="/nejaky/adresar" a vsechno ostatni se provede automaticky a jede to. Chybi vam tam zakladni knihovny, ktere bude potreba zkopirovat zrejme do podadresare /lib v adresari, odkud to spoustite. Plus vytvorit dalsi adresarovou strukturu vcetne /etc, kde bude prislusny konfiguracni soubor.

Pri pustani strace treba mysliet na to, ze ked aplikacia potrebuje zdielanu kniznicu tak ju moze hladat na viacerych miestach, takze ak open(.../libXY.so) ktore zlyha je nasledovane takym open(), ktore prejde tak je to ok.

Ale tiez je to tak, ze by som videl problem skor v chroot-ovani ako v bind-e. Nikdy som chroot nerobil ale domnievam sa,ze ci Gentoo alebo XY, stale sa ten kto chysta chroot prostredie musi postarat o to aby v tom prostredi bolo vsetko co program (v nasom pripade bind) potrebuje.
