Dynamic DNS를 해보려고,,내부네트웍을
 구성했습니다.
DNS는 192.168.0.2
동적아이피를 구현할 (nsupdate를 실행할호스트)는
 192.168.0.5
번입니다.

키생성하고,
private키 원격DNS에 복사해서..설정하고.


192.168.0.5에서 
nsupdate명령을 아래와 같이 내리니..
"; TSIG error with server: clocks are unsynchronized"라는
 에러가 나는데요???

이게 몰까요?
쉬운일이 없네요..

[root@venus named]# ls
Kdnskey_venus.+157+59546.key  Kdnskey_venus.+157+59546.private  localhost.zone 
named.ca  named.local
