周末工程 伊阿宋

周末工程 伊阿宋昨天晚上autro和今天上午,花了大约8小时,写了一个小程序。这个小程序的名字叫做Jason,不是英文的詹森,而是希腊神话里大名鼎鼎的伊
阿宋。叫这个名字的原因后面再说,先说说它的作用是这样的。1. 环境和需求
已知电驴支持WEB远程管理。
一台服务器工作在NAT之内,NAT的外网IP是电信链路,动态IP。
在NAT上做电驴和FTP的端口映射(虚拟服务器)。在这种情况下,如果知道NAT 的外网IP,就可以通过IP和端口访问NAT内网的电驴
WEB界面和FTP了。伊阿宋 能回答服务器的外网IP。2. 原理伊阿宋 是Emacs下的lisp程序,
调用了jabber.el。插话,jabber是用于网络聊天的协议,著名的Gtalk使用了这一协议,
另一个著名的聊天工具,MSN,也可以与jabber的服务器群(是这么叫么?)连
起来。还有一个著名的聊天工具 QQ, 也可以与它们相连,不同QQ协议是企业保
密的协议,不公开,反向工具是可能判有期徒刑的。jabber.el是工具在emacs下的jabber客户端,因此也可以视为
gtalk/msn/oicq/qq等的客户端。伊阿宋调用了jabber。当我在NAT外网――也可以是内网,举外网为例是说明它比较强大的意思――或者
任何地方用GTALK联系一下伊阿宋,它已经在NAT内网的一台计算机上运行了。伊阿宋接到GTALK聊天以后,会忽略绝大部分内容,如果没有人操作,看起来就
像一个挂在线上主人离开的GTALK。如果伊阿宋接收到的消息是"/ip",则视为指令,用curl(一个工具,不知请
GOOGLE之)访问某个可以获取外网IP(public IP)的站点,从而得到自己的外
网IP,然后这一IP用消息发送给刚刚发出"/ip"请求的GTALK用户。curl为什么能获取到请求者的外网IP呢?熟悉php/asp/jsp的同学一定知道这些
语言都支持获取浏览器客户端的IP等信息吧。curl在这里扮演了浏览器的角色。
事实上,你可以视curl为命令行的浏览器。伊阿宋把外网IP发送给我的GTALK客户端――上面提到,我在外网。然后我用外网IP加上事先就知道的端口,就可以在世界上任何有网络或有
GPRS/3G的地方,把要下载的电驴资源提交到我的电驴上――运行在NAT内网,配
置了web管理。电驴web管理界面的IP地址是,正是伊阿宋告诉我的。伊阿宋运行
在与电驴相同的NAT内网,具有相同的外网IP。最后,我还可以根据这一外网IP通过FTP下载或移除已经下完成的电驴资源,只
要设置电驴的incoming目录可以被FTP服务器访问就可以了。3. 命名这个小程序为啥叫伊阿宋呢?这个小子当年因为啥啥需要金羊毛,组织了个敢死队,历尽艰险。话说伊阿宋是个牛人,他的老师是个马人,错了,半人马。这匹半人马叫做喀戎,
是比伊阿宋还著名的――最著名的英雄赫拉克勒斯的老师,后来被赫英雄误伤死
了。而赫英雄做了N件伟业,像徒手杀狮子(载于初中语文课本来着),是后来阿喀硫
斯的偶像。阿喀硫斯,这个就牛到大部分人都知道了,就是 布拉德・比特 在特洛伊里扮演
的那个家伙。他的事迹,我就不赘述了。赫英雄的老师也教了伊阿宋。伊阿宋没啥太多的英雄事迹,不过似乎是个领导,
他带了一船人去整金羊毛,这一船人后来有N多都载入了史册。恩,载入了神话。其中有 赫拉克勒斯,刚才我们说过了;还有埃阿斯他爸,埃英雄在特洛伊中戏份
也不少,特洛伊里有两个非亲非故同名的埃阿斯,这个不知道是哪个的爸――查
到了,两位爸爸都在;还有阿喀琉斯他爸,这位兄弟娶了一位女海神,就是她整
出了阿喀硫斯的脚踵;还有忒修斯,后来是雅典的国王……这里N多都是宙斯的
儿子或者波塞东的儿子之类。总之,这么个富二代官二代,及后来的牛人的爹们组成的全明星队,居然拿不到
金羊毛。最后多亏了一位女巫 美狄亚,与我们有关的,她最大的优势就是她是内部人。她
喜欢上了英俊的伊阿宋,背叛了自己的祖国啥的,跟我们的评书里弃暗投明的肖
太后她姑娘有得一拼。伊阿宋答应并兑现诺言娶了美狄亚,但是后来他背信弃义抛弃了她。她诅咒伊阿
宋和并杀害了他们的两个儿子,跑了。后面悲惨的结局不是关键,伊阿宋是通过内部的美狄亚才取得了外网IP,从而得
到金羊毛,这是伊阿宋的故事的亮点。

    This will also happen if the overall content layout of your website does not meet the standards of this search engine.
    Hiring an seo clients are the most suitable choice for
    website promotion.

    in other states. The real estate of California is considered very important.
