http://www.opennet.ru/base/net/auto_dns_dhcp.txt.html вот может поможет

[slaine]

DNS работает, DHCP работает т.е. адреса раздаёт.
Но записи о хостах в файлах зон не появляются, всмысле файлы не обновляются.
файлы зон лежат все в /var/named/chroot/var/named

Вот мои конфиги, можт подскажите что:

Убедитесь что есть права для записи в /var/named/.

[slaine]

права сразу выставил 755, без изменений.

[BuGfiX]

Имелось в виду что эти права должны быть у пользователя, от которого работает named.

[slaine]

это где посмотреть?

[slaine]

По большому счёту, права в том, что не обновлялись зоны роли не играли.
Впринципе я разобрался что к чему.
solved

[dmitryst]

slaine, ну и напишите, как разобрались. Народу-то интересно

[slaine]

Я просто не внимательно сконфигурил файлы named.conf и dhcpd.conf.
named пытался обновить зону 1.168.192.in-addr.arpa, которую ему подсовывал dhcp,
когда в самом named.conf файл зоны назывался 1.168.192.
естествено записи не появлялись и мне этого в log'ах никто не говорил.
