Ubuntu 10.10下Dnsmasq和Named似有冲突[Linux安全]

　　我用的服务器版的Ubuntu 10.10.

　　装了个dnsmasq.完了老起不来.sudo /etc/init.d/dnsmasq restart

　　之后

　　提醒dnsmasq: failed to create listening socket: Address already in use [fail]

　　后来查英文文章,dnsmasq和其他dns解析服务都用53端口.

　　sudo netstat -anlp | grep -w LISTEN

　　一看53端口被named占用.但是我想本机又dnsmasq自己用,又起dns别的解析服务程序.

　　这便可以操纵端口绑定./etc/dnsmasq.conf这个文件中有阐明.

　　# On systems which support it, dnsmasq binds the wildcard address,

　　# even when it is listening on only some interfaces. It then discards

　　# requests that it shouldn't reply to. This has the advantage of

　　# working even when interfaces come and go and change address. If you

　　# want dnsmasq to really bind only the interfaces it is listening on,

　　# uncomment this option. About the only time you may need this is when

　　# running another nameserver on the same machine.

　　bind-interfaces

　　这行bind-interfaces之前是有井号的,把井号去了,保存.重启dnsmasq,我为我本机的lo口多加了一个127.0.0.2的地址.完了监听地址也绑到127.0.0.2上去.省的他老提醒我127.0.0.1的端口被占用.

　　listen-address=127.0.0.2

　　这样,把resolv.conf和dhclient.conf也相对的改了,后来就没事了.
