This lab is brief, as we’ll only examine the DHCP packets captured by a host. If you also have administrative access to your DHCP server, you may want to repeat this lab after making some configuration changes (such as the lease time). If you have a router at home, you most likely...

A1:ARP/DHCP/DNS Q2:从HTTP GET消息发送到HTTP OK回复需要多长时间? (默认情况下,分组列表窗口中的时间列的值是自Wireshark开始捕获以来的时间(以秒为单位)。要想以日期格式显示时间,请选择Wireshark的“视图”下拉菜单,然后选择“时间显示格式”,然后选择“日期和时间”。) ...
先伪造 DHCP: sudo msfconsole,然后 use auxiliary/server/dhcp 分别设置 DNSSERVER、SRVHOST 为本机 IP,NETMASK 设置为 255.255.255.0 set DNSSERVER 192.100.200.191 假的DNS 服务器地址 set SRVHOST 192.100.200.191 假的DHCP 服务器的地址 set NETMASK 255.255.255.0 ...
显示过滤器支持若干的过滤选项:源 MAC、目的 MAC、源 IP、目的 IP、TCP/UDP传输协议、应用层协议(HTTP, DHCP)、源端口 Port、目的端口 Port 等。在显示过滤器栏中输入过滤表达式(更详细的显示过滤语法可以查看 WireShark 的官方文档 1 ) 6. 通过主菜单“文件”/“导出特定分组”(如图1.1–6),可以保存捕获的...
1、使用DHCP获取IP地址 (1)打开命令窗口,启动Wireshark。 (2)输入“ipconfig/release”。这条命令会释放主机目前的IP地址,此时,主机IP地址会变为0.0.0.0 (3)然后输入“ipconfig/renew”命令。这条命令让主机获得一个网络配置,包括新的IP地址。 (4)等待,直到“ipconfig/renew”终止。然后再次输入“ipconfig/rene...
