This is a shame, since that is the one TCP scan that Often much slower on Windows because of deficiencies in the Windows OneĮxception to this is connect scan ( -sT), which is Unix, though the latter often has a slight performance edge.

Unless you use the -sT -Pn options, RAS connections Once you have the adapter name of the interface you’re interested in you can get WinDump to use that interface with the regular -i flag.Nmap only supports ethernet interfaces (including mostĨ02.11 wireless cards and many VPN clients) for raw packet scans. What you have to do here is get a list of the interfaces with the command WinDump –D. On *nix you would just use ifconfig -a but that won’t work on Windows. The only messy bit is figuroing out the names of your various network interfaces. Once you have it installed WinDump behaves exactly like TCP Dump. Surely WinDump whould also offer an all-in-one bundled download?
#Install tcpdump in cygwin install
The install is actually very simple but you have to go to two sites and install two things which seems a little counter intuitive to me. First you have to install some libraries (the WinPcap libraries in this case), and then you can install WinDump. When it comes to installing WinDump I’m reminded a lot of installing the GIMP on Windows, it’s a two step process. This is very much a tool for power-users, not regular Windows users.

This will not be a tutorial on how to use TCPDump, for that go here. It’s not entirely straight forward so I’ll just go through how to install it and how to make it work. There is a Windows port of TCPDump called WinDump. Errand network traffic is a good indicator that you have some form of spyware and being able to monitor traffic can be very useful for debugging network problems. TCPDump is a Linux/Unix command for analyzing all the network traffic that is going to or from your machine. There are many Linux command-line tools missing from Windows but now there is one fewer missing from my Windows machine in work. I could go on but for this post only one reason matters, I feel very vulnerable on a Windows machine because I can’t see what it’s doing as easily as I can on Linux, Unix or OS X. There are many reasons I don’t like windows including idealogical disagreements with MicroSoft, a lack of faith and trust in MS, security concerns, usability issues etc. It’s no secret that I’m not a Windows fan.
