Linux中与网络配置有关的文件 /etc/hosts 这个文件是把IP地址和主机名联系起来的简单文件。文件内容如下： # Do not remove the following line, or various programs # that require network functionality will fail. spring localhost.localdomain localhost /etc/services记录着端口号和服务之间的对应关系，这个文件不需要修改。文件内容如下 # /etc/services: # $Id: services,v 1.32 2003/01/09 17:56:30 dwalsh Exp $ # # Network services, Internet style # # Note that it is presently the policy of IANA to assign a single well-known # port number for both TCP and UDP; hence, most entries here have two entries # even if the protocol doesnt support UDP operations. # Updated from RFC 1700, ``Assigned Numbers (October 1994).

HOSTNAME=spring (主机名，要更改主机名可以修改此项，重启后生效。 GATEWAY=54 (配置主机的网关 /etc/host.conf 指定主机进行域名解析时的查找顺序。 order hosts,bind /etc/nsswitch.conf是由SUN公司开发的，用于管理系统中多个配置文件查找顺序，比/etc/host.conf功能多，我们一般不使用。文件内容如下： # /etc/nsswitch.conf # An example Name Service Switch config file. This file should be # sorted with the most-used services at the beginning. # The entry [NOTFOUND=return] means that the search for an # entry should stop if the search in the previous entry turned # up nothing.
