use /sbin/netconfig 命令更新/etc/resolv.conf文件

netconfig是用于设置网络环境的命令

haotianfei@tianfei-opensuse:/etc/sysconfig> sudo netconfig --help
Usage:
 netconfig <global options>
 netconfig <action> <action options>

 actions:
  modify    Requires an interface and service specific settings via STDIN
            or as file using the --input-file or --lease-file option.
            Already existing settings for this interface and service will
            be replaced with the new one, otherwise netconfig creates a
            new state file. Finaly, netconfig updates the managed files.
  remove    Removes the interface and service specific settings and
            updates the managed files.
  update    Updates the managed files with the current set of settings.
  batch     Executes a batch file with modify,remove,update action lines.
            Unlike in regular actions, modify and remove do not call update.

  [ -l|--lease-file <file name> ]       alias for --input-file
  [ -m|--module-only <name | prefix> ]  module or module group updates only
  [ -f|--force-replace ]                generate files, even user modified
  [ -v|--verbose ]                      enable debug and be verbose

 remove options:
  < -s|--service <service name> >       service providing settings
  [ -i|--interface <interface name> ]   interface providing settings
  [ -m|--module-only <name | prefix> ]  module or module group updates only
  [ -f|--force-replace ]                generate files, even user modified

注意help中的update,如果网络配置不正常,可以使用netconfig update -f强制修复
