如果是Linux机器的话用命令netstat -tp, 可以显示类似如下内容。
本地哪个端口连了远程哪个端口都有了。都不用手工每台机器上放一个程序。
直接pdsh netstat -tp, 然后分析输出的数据就行了。
牛人用几行脚本搞定的事情外行往往需要花一个星期写很多行程序才能勉强弄出来。
再不济的自己搞不定还要以面试之名找人来搞,并且给出一个暴露自己水平的面试题。

a*c 发帖数: 6 | 20 我碰到了一个很奇怪的问题:
platform: SUN Enterprise 420
OS: solaris 2.7 server
reboot之后, 我用netstat看socket的状况, 这时候
是htserver.4100....(htserver是这台机器的hostname. 4100
是一个server的端口). 这时候ping htserver
it will say:htserver is alive
但是, 大约55分钟后, 我用netstat看, 就变成了
cl188-33.invision.com.4100, 这是什么问题呢? DNS?
这时候ping htserver, it will say: htserver.xxx.com is alive
我今天一天就一直在试这台机器, 每次都是55分钟就会这样?
是我的solaris没配好? invision.com是公司的isp.
这个问题直接导致了我的一个database server 不能funtion,
因为它需要机器的hostname进行联接.
谢谢各位的回答.

你是否觉得自己从学校毕业的时候只做过小玩具一样的程序?走入职场后哪怕没有什么
经验也可以把以下这些课外练习走一遍(朋友的抱怨:学校课程总是从理论出发,作业
项目都看不出有什么实际作用,不如从工作中的需求出发)
建议:
不要乱买书,不要乱追新技术新名词,基础的东西经过很长时间积累而且还会在未来至
少10年通用。
回顾一下历史,看看历史上时间线上技术的发展,你才能明白明天会是什么样。
一定要动手,例子不管多么简单,建议至少自己手敲一遍看看是否理解了里头的细枝末
节。
一定要学会思考,思考为什么要这样,而不是那样。还要举一反三地思考。
注:你也许会很奇怪为什么下面的东西很偏Unix/Linux,这是因为我觉得Windows下的
编程可能会在未来很没有前途,原因如下:
现在的用户界面几乎被两个东西主宰了,1)Web,2)移动设备iOS或Android。Windows
的图形界面不吃香了。
越来越多的企业在用成本低性能高的Linux和各种开源技术来构架其系统,Windows的成
本太高了。
微软的东西变得太快了,很不持久,他们完全是在玩弄程序员。详情参见《Windows编
