關(guān)機(jī)后重啟電腦DNS/DHCP服務(wù)就失效了

indian

我用VM虛擬機(jī)安裝的FreeBSD 7.0 。安裝了DNS/DHCP服務(wù)。剛安裝完畢，重啟服務(wù)后，DNS和DHCP服務(wù)能正常運(yùn)行。局域網(wǎng)中其它的真實(shí)pc能自動獲取到IP。 下班后，我把虛擬機(jī)暫停，虛擬機(jī)所在的真實(shí)主機(jī)關(guān)機(jī)。第二天開機(jī)，啟動虛擬機(jī)。結(jié)果局域網(wǎng)中其它在真實(shí)pc無法自動獲取ip。虛擬機(jī)中提示：




并且我：

rndc status
rndc: connection to remote host closed
This may indicate that
* the remote server is using an older version of the command protocol,
* this host is not authorized to connect,
* the clocks are not syncronized, or
* the key is invalid.
tim@dev[/etc/namedb]# rndc flush
rndc: connection to remote host closed
This may indicate that
* the remote server is using an older version of the command protocol,
* this host is not authorized to connect,
* the clocks are not syncronized, or
* the key is invalid.



我查看 /etc/named/rndc.key 文件，并且將它的權(quán)限改為 755

tim@dev[/etc/namedb]# ls -Flob
total 36

drwxr-xr-x  2 bind  wheel  -   512 Nov 20 10:13 slave/




請問這是什么原因造成的？怎么解決？謝謝
