[Comm] DDNS: что я сделал неправильно?

[Eugene Prokopiev <john@rmts.donpac.ru>]

Здравствуйте!

Настроил DDNS так, как описано в 
http://www.atmsk.ru/index.php?option=articles&task=viewarticle&artid=72

Вот настройки сервера:

Вот настройки клиента:

# cat /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0
BOOTPROTO=dhcp
DHCP_HOSTNAME=ns2
NETMASK=255.255.255.0
ONBOOT=yes

После service network restart на клиенте:

/var/log/messages на клиенте:

Это тоже на сервере:

-rw-rw----    1 root     named           0 Apr  4 14:45 update.log

Это результаты dns-запроса:

Показать что-нибудь еще?
