4.5 Kernel running on RPi

Update your RPi to the latest 4.5 Kernel. Simply copy and paste these on your Raspberry Pi. You might need build essentials etc....

sudo apt-get install bc unzip -y
wget https://github.com/raspberrypi/linux/archive/rpi-4.5.y.zip
unzip rpi-4.5.y.zip
cd linux-rpi-4.5.y

"Tinder match" is a pun.

tshark -i eth0 -Y 'http.request.method == POST and tcp contains "password"' | grep password

tshark -i eth0 -f "src port 53" -n -T fields -e frame.time -e ip.src -e ip.dst -e dns.qry.name -e dns.resp.addr
tshark -i eth0 -Y http.request -T fields -e http.host -e http.user_agent
tshark -o column.format:""Source", "%s", "Destination", "%d"" -z conv,tcp
tcpdump -nn -v -i eth0 -s 1500 -c 1 'ether[20:2] == 0x2000'

You want to look busy, Simply run this.

cat /dev/urandom | hexdump -C | grep "ca fe"

It's weird how 'bottle of water' and 'water bottle' typically mean two different things.

Some commands and stuff for the Raspberry Pi, But also can be used on other Linux boxes too.

Securing your box a little bit more. Simply copy and paste these.

Block Windows 10 "Telemetry" with Cisco ACL's

Following on from the in-depth post here... https://voat.co/v/technology/comments/835741

I have created a Cisco ACL that blocks all traffic to the IP's listed.

Simply copy and paste this and apply this to your Interfaces on a Cisco Device.
