Конфигурирование DNS-клиента


/etc/resolv.conf :

domain          fedfond.msk.su

nameserver      127.0.0.1

;nameserver     128.8.2.1



/etc/defaultdomain :

/etc/host.conf :

order hosts, nis, bind

multi on

Как посмотреть зоны DNS


 nslookup -ty=ns  msk.ru

 zzz=msk.ru ; named-xfer -z $zzz -f filename ns.$zzz

 egrep '^[a-z]' filename | egrep -v A | grep NS| cut -f1 | sort -u| wc

или сходить в RIPE:
