电信到底是如何控制只让一台电脑上ADSL的？

husong9

我是湖北一个城市的，我们这里电信的ADSL用户一人一个帐号和密码，而且同一时间内一个ADSL帐号只能一台电脑用。现在想一条ADSL线路带多台电脑上网，可是安装了ADSL宽带路由器也不行，安装SYGATE和WINGATE等软件也不行，把ADSLmomden调试成PPPOE自动拨号也不行，用以上办法共享上网经常发生只能上一会就打不开网页了，但是PING电信的DNS却是通的。如果不调试成共享上网，只让一台电脑上网就没问题。还有就是如果找到几个ADSL的帐号和密码，让每台电脑都拨号也可以正常的多台一起上网，可是到哪里找的到那么多的帐号和密码呢。
电信局的到底是安装了什么控制软件或其他的控制方法？
如何解决，请全国的高手回答。
这个问题虽说和linux无关，但我想这里高手多，请斑主不要删除我的问题。

还好，我们这没这样。
我们能用的，而且给的宽带猫就可以直接调成ROUTE，加个HUB就好了多人一起上

哪位大虾可以从技术角度分析一下，他们是怎么实现这些功能的么？

好像不行，至少ip,tcp,udp協議肯定不行

Notice the following paragraph in this paper:

Passive fingerprinting can be used for several other purposes. It can be used by the bad guys as 'stealthy' fingerprinting. For example, to determine the Operating System of a 'potential victim', such as a webserver, one only needs to request a webpage from the server, then analyze the sniffer traces. This bypasses the need for using an active tool that can be detected by various IDS systems. Also, Passive Fingerprinting may be used to identify remote proxy firewalls. Since proxy firewalls rebuild connection for clients, it may be possible to ID the proxy firewalls based on the signatures we have discussed. Organizations can use Passive Fingerprinting to identify 'rogue' systems on their network. These would be systems that are not authorized on the network. For example, a Microsoft or Sun shop can quickly identify 'rogue' Linux or FreeBSD systems that mysteriously appeared on their network. Passive Fingerprinting can be used to quickly inventory an organizations operating systems without touching or imapcting any systems or network performance. You would be surprised how may organizations do not know what systems they have on their internal network. For individuals conducting security assessment, Passive Fingerprinting also allows one to quickly identify critical systems (such as Unisys Mainframe). This method can also be used to identify rogue or unautorized systetms or OS types within an organization, a possible indication of 'blackhat' activity.

Anyway, this company (www.glorysoft.com.cn) sucks! China telecom sucks! I wonder if there is any law/regulation that states sharing connection is ILLEGAL. These companies often consider something to be "ILLEGAL" because it hurts their interests. But in fact, there is NOT any law/regulation about the so-called "ILLEGAL" things at all. I think there should be a law/regulation to punish these companies for creating FAKE law/regulations!!!

Damn www.glorysoft.com.cn and China telecom!!!

能说说原理吗？
