如何改变主机IP地址解析顺序

zhangqy_unix

一般主机IP地址的解析顺序依次是DNS,NIS,本机host档案。\r\n要改变这个顺序,　可以建立一个/etc/netsvc.conf文件,并在这个档案中加一行:\r\nhosts=local,bind,nis\r\n\r\n\r\n这样主机IP地址就先从本地档案(/etc/hosts)开始搜索,其次再去DNS server,最後是NIS server。\r\n也可通过执行\r\nexport NSORDER=local,bind,nis\r\n改变环境变量NSORDER 来改变顺序

很多系统都由这个文件来指定： /etc/nsswitch.conf\r\nAIX上面就是这个文件/etc/netsvc.conf\r\n\r\n# The /etc/netsvc.conf file is used to specify the ordering of name resolution for\r\n# gethostbyname, gethostbyname2, gethostbyaddr routines\r\n# and alias resolution for the sendmail command.\r\n# Any host setting defined in /etc/netsvc.conf file will override the default host order\r\n# and the host setting given in the /etc/irs.conf file.\r\n# The environment variable NSORDER overrides the host settings in the /etc/netsvc.conf file,\r\n# which in turn overrides the host settings in the /etc/irs.conf file.
