dnsmasq的错误

DNSmasq出现如下错误：

tux@Neverland:/usr/share/virtualbox$ sudo service dnsmasq restart
 * Restarting DNS forwarder and DHCP server dnsmasq                            
dnsmasq: failed to bind DHCP server socket: Address already in use
                                                                         [fail]

看起来是端口被占用了。原来还开着bind9呢。把bind9禁止了就好了。
