Проблема с разрешением имен (DIG работает, PING - нет)

[vasilea]

Все очень просто и очень непонятно.
Настроен DNS сервер, но внутренние хосты не пигуются. То есть:
ping ya.ru - все нормально
dig или host admin.foo.local - тоже все отлично
ping admin,foo.local - выдает "не знаем мы такого хоста" - ???
С клиентских компов такая же история.
Может кто подскажет, где собака порылась?

[KiWi]

/etc/resolv.conf?

[vasilea]

### BEGIN INFO
#
#
### END INFO
#
nameserver 127.0.0.1
search sds.local
(это на сервере)

ping admin,foo.local - выдает "не знаем мы такого хоста" - ???

Прямо так и вводите?)
И вывод dig'а плз.
/etc/nsswitch.conf?

А вот nsswitch:

[nesk]

А вот nsswitch:
hosts: files mdns4_minimal [NOTFOUND=return] dns

Вполне типичная ситуация
напиши например так:

hosts: files dns

Вопрос не раз поднимался можешь даже по форуму поискать.
