SSH into your Raspberry Pi using brute force... Doesn't hax or anything, just attempts to connect to all the IP addresses in a range

brute_pi.sh

#!/bin/bash

user_name="${1:-pi}"
ip_range="${2:-192.168.1}"
ip_from="${3:-1}"
ip_to="${4:-99}"

echo -e "Attempting to connect to a pi with user name: ${user_name}\n"

for i in $(seq ${ip_from} ${ip_to})
  do
    echo -e "Trying with: ${ip_range}.$i\n"
    ssh ${user_name}@${ip_range}.$i
done
