新安装的rhel5服务器，刚开始两天没事，从昨天开始发现messages里面出现了一些错误信息，频率极高：

不晓得大家有没有遇见过这种问题？求大家解答，谢谢！服务器本身可以访问，不知道是不是网络的问题？还是机器网卡的问题？或是我设置的问题？我一般都采用默认的设置，自己没改的……

Avahi 是 zeroconf 协议的实现。它可以在没有 DNS 服务的局域网里发现基于 zeroconf 协议的设备和服务。它跟 mDNS 一样。除非你有兼容的设备或使用 zeroconf 协议的服务，否则应该关闭它。我把它关闭。”

所以我认为你根本用不到 把该服务直接关闭
/etc/init.d/avahi-daemon stop
/sbin/chkconfig avahi-daemon off

就是说DNS服务器会用到这个？而普通的服务器根本不用启动这个服务？

DNS服务器也用不到这个 你上网再了解一下
linux装机之后 默认会启动很多程序
有一部分基本是不必要的 最好都把他们关闭

好的，非常感谢！
