Homebrew’s package index. Name: Zenmap Multi-platform graphical interface for official Nmap Security Scanner. Homebrew’s package index.

  1. Homebrew’s package index.
  2. Installing Nmap Nmap is a multi-platform program that can be installed on all major operating systems. It was initially released as a Linux-only tool, and later it was ported to other systems such as BSD, Windows, and macOS. If you prefer a GUI over the command line, Nmap also has a graphical user interface called Zenmap.

I usefourdifferentadblockers for my browser, plus extensions that hide various things like the Facebook timeline (I only really need Messenger + Events these days) or hide reposts on Soundcloud.

The web is increasingly funded by garbage & bloat that comes packaged along with the content you want to see. I happily pay for online services (Spotify, Soundcloud, Evernote, etc) but many services, like Facebook or random news sites don’t offer this. Nor do I want to subscribe to every news website - my friend sent me a random link to click on, I don’t want a lifetime subscription.

It’s not just about seeing annoying ads, it’s about privacy (being tracked by ad networks), page load time (have you tried loading CNET.com lately???), safety (malware), and for mobile clients, minimzing data usage. Thus, Adblockers have started to become more mainstream.

But what about native apps? Or using my iPhone / Android?

Now you can even do that.

Pihole is a nice way to set up a homegrown server on a Raspberry Pi that filters every web request you make - even on smartphones, iPads - anything on your Wifi network.

Here’s the dead simple instructions. From start to finish this took me less than an hour.

Setting up Headless (no Monitor) Pihole

Brew Nmap

You can set up a headless Pihole with just a Raspberry Pi, a power cable that comes with it, your laptop, and an SD card. No need for mouse, keyboard, or monitor.

Brew Upgrade Nmap

  1. Order a Raspberry Pi. I like the 3B since it has decent storage + Wifi. It was $27.
  2. You have to load an operating system (OS) image (from here) onto SD card. The Pi can’t boot without an SD card with a boot image on it. I choose RASPBIAN STRETCH LITE.
  3. Download the ZIP of the OS image.
  4. Install Etcher.
  5. Feed ZIP into Etcher and burn image onto SD card.
  6. Reload the SD card onto your computer - should be called “boot”.
  7. Execute the following in the terminal:
  8. Eject the SD card, put it into the Pi.
  9. It should use this boot image, boot OS, and start the SSH server.
  10. Install nmap:
  11. Find local IP in Mac OS X: System Preference > Network, should be like 10.0.0.x or 192.168.x.x.
  12. Find devices connected to the same Wifi network:
  13. For each IP address, try the following:
  14. Eventually, you’ll see the following:
  15. Type ‘yes’, type the password ‘raspberry’, and you’re in.
  16. To set locale, timezone, Wifi SSID + password (if Wifi enabled Pi):
  17. Then change the password:
  18. Then run PiHole installer: curl -sSL https://install.pi-hole.net | bash.
    • Choose a static IP address, remember this.
    • Mostly can just stick with the defaults
  19. Restart the Pi to take that <static-IP-address> into account
  20. SSH back into the Pi with: ssh pi@<static-IP-address>
  21. We confirmed that Pihole is running. Great.
  22. Go to your iPhone and go to your Wifi network (same network Pi is running on or plugged into modem/router)
  23. Change DNS setting to first use your Pihole’s static IP <static-IP-address>
    • I’d also recommend removing Comcast or insert-other-shitty-ISP’s DNS server as well
    • If you’re worried about the Pi going offline or whatever, stick 8.8.8.8 and 8.8.4.4 (Google’s DNS servers) at the end of the list
    • If you’re even more privacy conscious, look up OpenDNS and use their DNS server IP addresses
  24. Now you’re good to go! Try visiting CNET.com on your iPhone browser and watch the blissful speed you get and lack of ads as you scroll down.

Pretty easy.

Admin Panel

Visit it at http://<static-pihole-ip-address>/admin.

Here you can manage blocklists, see how much blocking is going on, and even watch logs to see requests come through in realtime.

Or even the top blocked tracking domains:

After using for a couple hours I was shocked - around 30% of all requests made on my iPhone were adservers, trackers, and/or malware.

Setting up passwordless SSH

It’s annoying to log into the Pi all the time without this. To add SSH passwordless login:

And add to ~/.ssh/config:

Now you should be able to do:

Blocklists are located at: /etc/pihole/adlists.list. To change the lists:

Comment out with # any you don’t want, or add more. Then to reload the blocklists:

To see what is being blocked in realtime:

For example, in the first 100 ms when opening Messenger (blocked ones are with [query] label):

Wow.

Happy Pihole-ing!

if I want to submit a pull request, should I be doing it to mainline libpcap, not to the nmap fork?

If it's a change to a libpcap file such as pcap-npf.c, yes, submit it to mainline libpcap, so it won't be a difference between mainline libpcap and the nmap fork that will have to be maintained forever. Daniel can pick it up for the fork so it can show up in Npcap before it shows up in a main libpcap release.

Hi,

I noticed that python file under this project using shebang like : #!/usr/bin/env pythonAs we know, python2 already EOL since Jan 2020. So I suppose we will also only support python3, right?

if yes, the best shebang should be #!/usr/bin/env python3. Since python maybe not exist on some distro.refer https://www.python.org/dev/peps/pep-0394/

Fix -sU modifying payloads when retrieving them. Closes #2269. Fixes #2268

issue closednmap/nmap

DescriptionWhile working on PR #2266 I've noticed that UDP scan: nmap -n -sU -p427 <target> does not correctly detects OpenSLP service:

While service detection scan: nmap -n -sU -p427 <target> -sV detects it as expected:

Even though payload in nmap-payloads is correct and equivalent to probe innmap-service-probe, specifically nmap-payloads payload:

nmap-service-probe probe:

After observing the nmap-payloads packet that is acutally sent (under wireshark) it can be indeed observed that it is malformed and different than the one that is in nmap-payloads file:

Whereas service detection probe (-sV) sends correct packet: Ntfs for mac os x keygen.

Root cause

After spending some time in the debugger I found subtle issue that caused corrupting the packets. The issue was introduced in commit 9c83be38331adff3d23b154eadace9263edfab48.

At https://github.com/nmap/nmap/blob/master/payload.cc#L318 we can see std::vector declared locally (on the stack); at https://github.com/nmap/nmap/blob/master/payload.cc#L332 iterator is created for this vector; finally at https://github.com/nmap/nmap/blob/master/payload.cc#L343 the pointer to the data of locally declared vector is returned.
