新手入门之ping为何物

Ping对老鸟来说,实在太普通不过了,几乎每天都会用到它,而对于新手来说,多多少少会有点陌生,作为常用的一个工具,了解它非常必要。ping来源于物理学,是用来测声纳脉冲的回应情况的,在网络中是一种关于协议的常用工具,主要用来检测分析网络连接的状况。

Ping是通过命令的方式,来发挥其工具作用的,首先在开始菜单里找到“运行”项,输入cmd由此打开命令编辑窗口。开始进入ping的世界。

怎样使用Ping命令来测试网络连通

1. 输入命令“ipconfig /all”观察本地网络设置,加深对自己机器资料的了解,查看设置是否正确,如图:

图一

 
 
2. “ping 127.0.0.1”命令在本机上做回路测试,用来验证本机的TCP/IP协议簇是否被正确安装。 “ping 127.1”这个命令也能得到同样的测试结果。如果本地址无法Ping通,则表明本地机TCP/IP协议不能正常工作。

图二

3. Ping本机IP地址,这样可以检查本机的IP地址是否设置情况;

图三

 
 
4.为了检查硬件设备是否有问题,可以Ping本网网关或本网IP地址,这样的也可以检查本机与本地网络连接是否正常。

图四

 
 
5. Ping远程IP地址,命令语句可以是ping+域名也可以使ping+ip,通过该命令主要是检查本机与外部的连接是否正常。如检测与百度的连接状况:

图五
 

"time=43ms"是往返时间。 Sent 发送数据包、Received 收到回应包、Lost 是丢弃数据包个数。Minmum 、MAXimun、Average 后面是最值和平均值。从上图来看,来回用了43MS,说明网络连接状态良好。

Ping不仅有检测功能,还可以通过返回的结果去分析网络状况。比如当返回Unknown host的时候,说明该远程主机的名字不能被域名服务器(DNS)转换成IP地址。故障原因可能是域名服务器有故障,或者其名字不正确,或者网络管理员的系统与远程主机之间的通信线路有故障。知道状况才能做进一步处理。

新的课程改革目标, 就是要体现时代要求,使学生具有爱国主义、集体主义精神,热爱社会主义,继承和发扬中华民族的优良传统和革命传统;具有社会主义民主法制意识,遵守国家法律和社会公德;逐步形成正确的世界观、人生观、价值观;具有社会责任感,努力为人民服务;具有初步的创新精神、实践能力、科学和人文素养以及环境意识;具有适应终身学习的基础知识、基本技能和学习方法;具有健壮的体魄和良好的心理素质,养成健康的审美情趣和生活方式,成为有理想、有道德、有文化、有纪律的一代新人。实施新课程改革,主要反映在“旧与新”、“俗与雅”和“虚与实”等矛盾上。   旧与新。和旧思想、旧观念、旧方法相联系的是一种匠气,是经验型教师的不良习气。匠气产生于传统的学校观念—“学校被视为工厂、教师被视为工匠、学生被视为可以机械加工的材料”,学校只能按一种教学内容、一种教学模式培养社会需要的“标准件”似的学生。匠气是实施新课改的第一个大敌。和新思想、新观念、新方法相联系的是“新气”,即创新之气、′改革之气、科研之气,就是研究型教师之气。有“新气”的人呼唤改革,喜欢创新,工作有热情,爱学习、态度积极、乐观,不断超越自我,逐步形成自己教学思想,教学风格。.因此,在学校课程改革中,要大力提倡这种“新气”,如果学校“新气”占了上风,传统的教育准则就会被打破,逐步形成新的教风、学风和校风,从而真正

实现学校的内涵发展。

  俗与雅。俗表现一种俗气。有的学校愿意花巨资修建大门,却不愿花钱购置图书、教学仪器:有的学校舍得花钱搞奠基、剪彩等庆典活动,却不舍得花钱让教师参加培训学习:有的学校热衷于花时间让师生搞迎检、观摩课排练等活动,缺不愿花时间让学生参与实践活动;有个别教师有时间吃喝应酬,甚至参与赌博,却没有时间读书学习。这就是俗气的表现,是社会上教育功利化倾向、思想浅薄化倾向和趣味庸俗化倾向在学校的反映。学校里如果俗气占了上风,社会上的不良习气在学校里就有

了市场,学校实施各项改革就会步履艰难。譬如,有个别俗气的人违背教师职业道德以教谋私,以牺牲学生身心健康为代价获得一些名和利,不讲贡献只讲价钱,等等。如果这样的人多了,课程改革、素质教育、师德教育等工作就很难开展。和“俗气”相反的是雅气。雅气的人高雅,识大体、顾大局、爱思考、有见地,自信自强、宽容大度,爱读书、好钻研:雅气的人文雅,表现为举止文明、礼貌待人、生活健康、有情趣、品位高;雅气的人儒雅高洁,为人师表、师德高尚、热爱生活、精神充实、志存高远、追寻理想。学校是师生探究知识、启迪智慧、陶冶情操、塑造心灵、追寻理想的精神家园。而知识、智慧、情操、心灵和理想都是满足师生高雅的精神需求的。当前实施新课改,正是为了把我们的学校建成这样的精神家园。

  虚与实。虚与实的矛盾就是虚假与真实、浮躁与安静、懒惰与勤快的矛盾。躁气是实施新课改、促进内涵发展的又一大敌,是社会个性浮躁化、精神空虚化倾向在学校的反映。譬如有的学校重视盖大楼、不重视严格管理,喜欢做表面文章、不愿踏踏实实搞课改:有个别的教师,不努力学习钻研,抄袭剽窃论文,学风文风败坏等,这都是躁气在学校的表现。和躁气相反的是静气,静气就是平和安静之气。静气的人特点有三个,一是安静,心态平静、做事安静、遇事冷静,能坐得住、耐得住寂寞、办事认真、细致、工作尽职尽责;二是真实,就是陶行知先生所倡导的那种“求真”的“真人”,他们踏实肯干、求真务实、诚信质朴、宽厚仁慈;三是勤快,静气的人勤劳勤勉、刻苦努力、坚忍不拔、持之以恒。正是教师劳动的特殊性、教育工作周期长和迟效性的特点,决定了我们实施课程改革、提高教育

教学质量、实现内涵发展更需要静气,需要大批静气的人。

  处理好,“新与旧、俗与雅、虚与实”的矛盾,需要努力做到弃去匠气、树立新气,弃去俗气、树立雅气,弃去躁气、树立静气。只有这样,才会深化基础教育课程改革,促进学校内涵发展。
