标题: [求助]关与TELNET的很菜的问题 [打印本页]

作者: wssky0214 时间: 2004-11-28 16:27 标题: [求助]关与TELNET的很菜的问题

我运行了TELNET命令如果通了的话是不是代表我就有机会可以连接上对方的机子呢?
后面要要输入个LOGON PASSWORD(注册密码)请问着个怎么样才能得到!
希望有人能给我详细解释下关于TELNET的入侵或者连接,谢谢了先!

(真衰..是shadow过的密码档....也难怪用anonymous就能抓下来..如果就只有这个的话
就无法解开密码了....但是可以从面的帐号知道fatman有提供那些服务.像是uucp .
mail . ftp . news ...operator是开机用的,所以没有用.daemon是用来分佩每一个帐号
的权限用的)

嗯~~接著上次还没说完的话题..
上次是拿到了已经shadow过的/etc/passwd!!别以为它没有用喔...呵呵..虽然不能直接用
它还破解密码.但是它也为我们收集到一些系统的资讯..现在就在把它拿出来看看吧...

(/etc/passwd既然已经到手了...接下来的事你应该知道吧..啥??不知道吗???..那麽就在
此解说一下好了...)
[Love-gone的话]
拿到密码档(/etc/passwd)要做的就是破解它呀...看来我必须在这说明一下passwd的
格式和意义了...
例如:
root:L3mUc0CQtJbtQ:0:0:root:/root:/bin/bash
密码格式大多都是这个样子的.然每一栏都是用分号分开的..大多是6个分号...当然密码
格式有很多种..据我所知.目前我看过的密码格式有5种了...但是大多数应该都是用6个分
号的这种为多..然而每一栏代表的意义如下..
root:使用者名称
L3mUc0CQtJbtQ:是已经经过编译的密码(coded-password)
0:UID(User Identification Number),就是使用者辨识码
0:GID,就是使用群组的辨识码
root:comments,解栏..可能是电话号码or住址
/root:home directory,就是所谓的来源目录..即你的工作目录
/bin/bash:这一栏是表示使用者签入系统,第一个执行的程式
因为是已经编译过的单向密码(One-Way Passwd),所以不可能反组译....就只能使用所谓
的暴力破解法了..关於暴力破解法的程式有很多..在此就不讨论了解!我想你应该都知道
才对..什麽??说我无情??..好吧!!建议你我用的是John4.0

谢谢1楼的朋友~虽然没有给我解释但是给的着骗教程
也让我明白不少命令和用法

作者: navycool 时间: 2004-11-29 21:28 标题: [求助]关与TELNET的很菜的问题

其实认真看还是能看懂的,主要是没有机会练习一下~~不知道站长能否给大家提供一个练习的平台,那对大家水平提高一定有很大帮助~~
