网络老问题(烦苦命，ading都进来看看)
最近，本人机子在网上几乎每隔20分钟就断一次，一次大约15秒左右时间，极不正常，不知是本人的机子有问题，还是公司的路由受到攻击？概况：本人所在局域网由一台路由加N台交换机、N台电脑组成，4M光纤接入。以前由网通直接路由对路由，现在中间加了一个防火墙（硬件）。
据了解，局域网内也发现有类似情况。。。。。。。
我简单测了一下，情况如下：

(疑问：tracert出来的地址：66.116.125.170非本机地址，本机内网在址在上，而这个地址也不是电信提供的外网地址。。。。。。) 苦命是谁啊？
这么厉害

其中：Reply from 127.0.0.1: bytes=32 time<1ms TTL=64 与=128 有什么区别，都正常吗？ [quote]原帖由 [i]xianjianda[/i] 于 2006-12-22 14:49 发表

你不用管他是谁，只要你电脑有问题，找他就对了。。。。。。 :loveliness:
专业人专门解决让人眼晕的专业问题 看下 NETSTAT 。。。
另外硬件放火 和 路右之间的搭配问题 一定要注意！！
正在整机子 不想翻书鸟 自己找下 谢谢！
回复 #4 zc 的帖子
知道了啊 我个人感觉是集线太多鸟． TTL=64 表示你ping的系统是Linux128 是Win NT/2000/XP
32是Win98
255是UINX(忘了怎么拼了~~) TTL=64 表示你ping的系统是Linux
判断对方的系统有什么用? 其中：Reply from 127.0.0.1: bytes=32 time<1ms TTL=64 与=128 有什么区别，都正常吗？
他问了,那就回答他 ...命命 你入侵不判断对方系统？？？？？？？？？？
=。= 不素ARP吧？ 前面包括我上一次发的贴子，我都看了，个人分析了一下原因，好像都不是。。。。。。不过，我最近又有一个新发现，白天上班的时候，这种情况是存在的，但到了晚上，尤其过了9点以后，情况变得好多了，至少断线现象消失了。。。。。。难道是公司有多人在搞巨量下载，造成网络拥塞？？？可是，局域网内最多也就80多台机子，估计同时使用的最大流量，也不过四、五十台，怎么会呢？还是搞不懂。。。。。。。 [quote]原帖由 [i]冰尘[/i] 于 2006-12-25 03:42 发表

我入侵的时候扫描软件自动会提示我对方的系统以及开的服务,然后我会自己再去找他的其他的服务,最后总结一下想一个比较容易进去的方式..
这就是入侵了.. =。= 小白 入侵 100法 =。= 我还有不到一年就网络工程师毕业了，到时候应该能够帮的上你了。 楼上滴，你再快点行不。。。。。。。
