Installing TCPDump on a Windows System
WinDump — TCPDump for Windows — depends on a library named pcap , a
packet capture library. You can download both WinDump and pcap at the same
website: http://www.winpcap.org/windump/install/default.htm .
To install, follow these steps:
1. Download the WinPcap self-installer and run it. The fi rst screen of the
installer appears as shown in Figure B-1. Click Next.

2. Accept the defaults, including the Automatically Start Driver at Boot Time
option.
3. After WinPcap has been successfully installed, download WinDump itself.
This isn't distributed in an installable package, but is instead distributed
simply as an executable. Download it and put it somewhere in your path;
c:\windows\system32 will work.
Unfortunately, Windows doesn't provide an equivalent of Linux's loopback
adapter. This means that if you want to sniff traffi c, you have to sniff traffi c
remotely; either network two computers together and install the sample servers
on a remote one, or connect to an external computer over the public Internet
and sniff that traffi c.
