SharkTap Gigabit Network Sniffer
The SharkTap is a special purpose ethernet switch that allows you to 'tap into' an ethernet connection. It is intended to be used with the free Wireshark network analyzer or equivalent.Conventional switches route packets only to the intended destination port, reducing traffic, but preventing a third port from seeing all packets. The SharkTap duplicates all packets to or from the 'NETWORK' ports on the 'TAP' port.Supports 10, 100 and 1000Base-T, all ports. Power-Over-Ethernet (POE) pass-through on the 'NETWORK' ports.Powered from a micro-USB cable (included), draws 350mA or less. For USB TAP, search 'SharkTapUSB'Other features: Auto-MDIX, so no crossover cables ever needed. Non-conductive enclosure. Will not route packets from TAP to NETWORK ports.

Wireshark works on Windows and even has a pretty GUI. It can save packet captures in a tcpdump-compatible format (among others). It even has a portable version if you don't want to install programs.

Aside from Wireshark, you can mirror a port in your switch, or if you can't do that, get a hardware network tap (like this) and then run Wireshark/tcpdump/whatever on a laptop connected to the tap port.

No.

If you go wired instead of wireless you could use a network tap. You will see other traffic (ARP, etc.) but I don't think there's a way to solve this regardless of the solution, not from the hardware side. It is easy enough to filter out in Wireshark though.

Or much cheaper, but not bi-directional unless you reassemble the streams:

Or some USB NICs and use computer.

I love these: https://www.amazon.com/midBit-Technologies-LLC-100-1000/dp/B0175EODCE/ref=sr_1_1?ie=UTF8&qid=1521726003&sr=8-1&keywords=sharktap

... but I've seen where I need 4 or more captures and only have one or 2 of those available... I've used 10M hubs only a few times but those times were lifesavers.

u/AtmaJnana · 2 pointsr/raspberry_pi

Not, strictly speaking, true. e.g.: https://smile.amazon.com/midBit-Technologies-LLC-100-1000/dp/B0175EODCE

Stuff to think about:

  • What media type are you talking about?
  • Power/backup considerations? No problem for tactical use, but permanent taps might hurt you.
  • Be aware that passive 1000BASE-T taps don't exist.
  • Do you want an aggregator (oversubscribed) tap, or a full-duplex tap?

    Enterprise quality taps are expensive, but pocket-sized managed switches with mirror functions are cheap.

    This thing is pretty much the same as that little switch, but with no UI to configure behavior.

gigabit taps are available - https://www.amazon . com/midBit-Technologies-LLC-100-1000/dp/B0175EODCE/

You need one of these between the router and the wall to run wire-shark on ->https://www.amazon.com/midBit-Technologies-LLC-100-1000/dp/B0175EODCE/ref=sr_1_4?keywords=network+tap&qid=1556664438&s=gateway&sr=8-4

u/letopeto · 1 pointr/HomeNetworking

Ah... this might be the reason why I'm not picking up the traffic on wireshark through my PC.

Do I need something like this?

Why you should care about encrypting and anonymizing your internet traffic, and how to build your very own Raspberry Pi TOR project.



RasPi AP



Steps

  1. Image Raspbian onto your SD card

  2. Expand the volume

    -- Open Terminal

    -- "sudo raspi-config"

    -- Select option 1



  3. Change the default password

    -- Select option 2



    ** RasPi will Reboot



  4. Turn your RasPi into an Access Point

  • A GIT user by the name of "Harry Allerston" created a script to automate the process

    -- Open Terminal

    -- "git clone https://github.com/unixabg/RPI-Wireless-Hotspot.git"

    -- "cd RPI-Wireless-Hotspot"

    -- "sudo ./install"

    -- "Y" to agree to terms

    -- "Y" to use preconfigured DNS

    -- "Y" to use Unblock-Us DNS servers

    -- "N" for WiFi defaults

    -- Type in a new WiFi password (it will be checked)

    -- Type in a new SSID

    -- Type in your desired WiFi channel (1, 6, 11)

    -- Type "N" when asked - "Are you using a rtl871x chipset?" --

    -- Type "N" for chromecast support (unless you plan to use a chromecast w/RasTor)



    ** Your Pi will reboot



  1. Update your Raspbian installation

  • Open Terminal

  • "sudo apt-get update"

    • "apt-get" is a diagnostic tool that updates all packages and checks for broken dependencies







      What's in your traffic stream?



      Why should we care about encrypting/anonymizing our traffic?



      The easiest way to explain this is to show you what can be seen by your ISP.



      Parts and Tools

  1. "SharkTap" Gigabit Network Sniffer ~$180 https://www.amazon.com/midBit-Technologies-LLC-100-1000/dp/B0175EODCE/ref=sr_1_1?ie=UTF8&qid=1491429802&sr=8-1&keywords=shark+tap

  2. Wireshark (Windows and OSX) FREE https://www.wireshark.org/



    RasPi TOR



    Steps

  3. Install TOR

    -- "sudo apt-get install tor"

    -- "Y" on "continue?"



  4. Configure TOR

    -- "sudo nano /etc/tor/torrc"

    -- Add the following just below the first set of comments

    Log notice file /var/log/tor/notices.log

    VirtualAddrNetwork 10.192.0.0/10

    AutomapHostsSuffixes .onion,.exit

    AutomapHostsOnResolve 1

    TransPort 9040

    TransListenAddress 192.168.42.1

    DNSPort 53

    DNSListenAddress 192.168.42.1"



  5. Dump all the old rules from the iptable

    -- "sudo iptables -F"

    -- "sudo iptables -t nat -F"

    • iptables lets you configure the rules of the Linux Kernel Firewall.

    • It allow you to define how packets are treated

    • We're using it to route traffic through TOR



  6. Route DNS through the TOR

    -- "sudo iptables -t nat -A PREROUTING -i wlan0 -p udp --dport 53 -j REDIRECT --to-ports 53"



  7. Route all TCP traffic through the TOR

    -- "sudo iptables -t nat -A PREROUTING -i wlan0 -p tcp --syn -j REDIRECT --to-ports 9040"



  8. Check your routes

    -- "sudo iptables -t nat -L"



  9. Save our new rules to the NAT table

    "sudo sh -c "iptables-save > /etc/iptables.ipv4.nat""



  10. Create log file

    -- "sudo touch /var/log/tor/notices.log"

    • "touch" creates an empty file

      -- "sudo chown debian-tor /var/log/tor/notices.log"

    • "chown" changes the ownership of a fille (so that TOR can use it)

      -- "sudo chmod 644 /var/log/tor/notices.log"

    • "chmod" is the "change mode" command - it changes permissions

      600 : Only owner can read/write

       644 : Only owner can write, others can read

      *** 666 : All uses can read/write.



  11. Start the TOR service

    -- "sudo service tor start"



  12. Check to see if the service is running

    -- "sudo service tor status"



  13. Change the service to start on boot

    -- "sudo update-rc.d tor enable"



    Be Sure to Include this text in the notes!!!

    "* Install the WiFi Hotspot

    git clone https://github.com/unixabg/RPI-Wireless-Hotspot.git

    cd RPI-Wireless-Hotspot

    sudo ./install



    Install TOR

    sudo apt-get install tor



    Configure TOR

    sudo nano /etc/tor/torrc



    Add the following to the config file

    Log notice file /var/log/tor/notices.log

    VirtualAddrNetwork 10.192.0.0/10

    AutomapHostsSuffixes .onion,.exit

    AutomapHostsOnResolve 1

    TransPort 9040

    TransListenAddress 192.168.42.1

    DNSPort 53

    DNSListenAddress 192.168.42.1



    Dump iptable

    sudo iptables -t nat -A PREROUTING -i wlan0 -p tcp --syn -j REDIRECT --to-ports 9040



    Check Routes

    sudo iptables -t nat -L



    Save routes

    sudo sh -c ""iptables-save > /etc/iptables.ipv4.nat""



    Create Log File

    sudo touch /var/log/tor/notices.log

    sudo chown debian-tor /var/log/tor/notices.log

    sudo chmod 644 /var/log/tor/notices.log



    Start TOR

    sudo service tor start



    Check TOR

    sudo service tor status



    Set TOR to start on boot

    sudo update-rc.d tor enable
