Install Winpcap Without Admin Rights
Evilrix is correct - you need admin rights to install WinPCap, mainly because you are installing a device driver onto the machine, and access to the directory into which device drivers are needed usually is limited. However, there is an option: Get yourself a small hub (it's got to be a hub, not a switch). A tiny 4-port or 5-port hub is ideal. Ideal is 100Mbps nowadays, but some companies make 10/100 switchable hubs (but you must get one with a manual switch like the DLink). If that doesn't work, you'll need a more expensive 'managed switch' with the capability of port 'spanning' or 'mirroring' built in. My personal favoreite is the Linksys SLM2005 - a tiny 5-port managed switch capable of Gigabit speeds and spanning. With a switch, you must configure spanning, but I configure mine to span permanently.
Anyway, once the hardware is in place in-line to the machine you want to trace, add your laptop to the hub (or span port) and turn on tracing - you should now see all traffic to and from the target machine (if you set up spanning correctly). Note that the process of adding hardware can substantially change the network design, and can introduce problems into the environment that were not there previously, or it can hide existing problems. As such, this is not an IDEAL solution. Of course, adding Wireshark to a tareget machine ALSO changes the target machine, so Heisenberg's uncertainty principle still holds true - observing the environment inherently changes it.

Technically, there should be no problem with using Nmap without WinPcap or Npcap for the features that do not use those libraries, since we do delayed loading of the DLL. In practice, however, there were some bugs preventing it from working really well.
I've fixed those in r36227-r36229, so the next release will work as smoothly on Windows without Npcap as Nmap on Linux without root privilege does. In the meantime, I think you just have to be more explicit regarding what features to use: force Nmap to use TCP connect calls for host discovery and port scanning, and avoid trying to load Npcap by telling it you're 'unprivileged.' Here's an example, equivalent of 'nmap scanme.nmap.org': nmap -unprivileged -PT80,443 -sT scanme.nmap.org Dan On Wed, Aug 31, 2016 at 2:42 PM, Volodimir Kulakov wrote: Hi Guys, You do very good job, But I have one question regarding to nmap.
We need: to do network scan from windows (it`s terrible) by nmap without installation and admin rights. (I know about user space scan limitations, but we need only tcp connect scan) We did: We unpacked binary, copied WinPcap dll libraries and ms120 libraries to folder with nmap, but nmap works only if we copy nfs.sys driver to windows/system32/drivers. Based on our task we cannot modify any system folders. So, question: Is any way to run nmap just a portable application? May we need recompile it or copy any additional libraries?
Hello World, Today i have tutorial showing you guys how to install any software with out knowing the administrator password, Or if you computer is. I'm sure I've installed winpcap without admin on a system before. But now I'm getting 'Cannot install file c: windows system32 npf.sys'.
With the best regards, Vladimir. Norton ghost 11.5.1. We spent a lot of time but anyway cannot do nmap scan from windows Sent through the dev mailing list Archived at Sent through the dev mailing list Archived at Current thread:.
