	if self.platform == 'openbsd':
	# openbsd doesn't support -e, just drop it
	thiscmd = "%s -n %s" % (self.sysctl_cmd, token)
	else:
	thiscmd = "%s -e -n %s" % (self.sysctl_cmd, token)

[iyunv@lianke ~]# sysctl -e -n net.ipv4.ip_local_reserved_ports
21-22,24

由此可知，net.ipv4.ip_local_reserved_ports在proc文件系统会将连续的端口使用“-”连接，yml文件中的value是逗号分割，而获取到的value中有中横线分隔。
