DNSの入れ替えを企むので、もう一度BND9のおさらい

bind9 を最新のモノに入れ替える

#portinstall dns/bind9

portでBIND9をインストールすると、もともと有った/etc/namedb -> /var/named/etc/namedb へのリンクが無くなる場合がります。 bind.pngオプション指定で、もともとのBINDを入れ替えることにする。 いきなりエラー!?

make: don't know how to make /usr/ports/dns/bind9/work/.build_done.bind9._usr_local. Stop
*** Error code 2  
Stop in /usr/ports/dns/bind9.
** Command failed [exit code 1]: /usr/bin/script -qa /tmp/portinstall20100217-64536-10phvg0-0 env make
** Fix the problem and try again.

*       If you are running BIND 9 in a chroot environment, make         *
*       sure that there is a /dev/random device in the chroot.          *
*                                                                       *
*       BIND 9 also requires configuration of rndc, including a         *
*       "secret" key.  The easiest, and most secure way to configure    *
*       rndc is to run 'rndc-confgen -a' to generate the proper conf    *
*       file, with a new random key, and appropriate file permissions.  *
*                                                                       *
*       The /etc/rc.d/named script in the base will do both for you.    *

*       through the lifetime of the RELENG_6 branch, currently          *
*       scheduled to be supported through 30 November 2010.             *

でアップグレード完了。でも、936は本年までの寿命?なんだとか・・・・

既にBindは稼働中なので、以下は、

# cd /etc/namedb/
# rndc-confgen -a
wrote key file "/etc/namedb/rndc.key"
# cat /etc/namedb/rndc.key > /etc/namedb/rndc.conf

設定済みで、keyは作り直し
