Netcat file transfer chat utility send receive files

Netcat Scheduled Server / Client File Transfer Script

Using Netcat may be “Old School”, but so am I, so I love using Netcat for simple tasks or just chatting without Big Brother paying too much attention. I love using Bold Text too.

These are two separate scripts, one for use on a server, “server.sh” (home pc/Pi/laptop or and server that allows you to use Netcat) and “client.sh”, which you can use on your Android or Laptop etc from a mobile location.
Of course you’re going to have to set permissions and run them. I highly suggest editing out the sleep function and using cron if you’re savvy as this is really meant to update files such as remote sensors, cameras etc.

*Edit the IP address to your server in client.sh.

server.sh

#!/bin/bash
clear
    echo "Server Running."
        mkdir incoming
    date="$(date +'%Y-%m-%d_%H-%M')"
    file="incoming/payload.file"
# Set the Servers Port To Listen On
    echo $(nc -l 1234 > $file)
        mv $file "incoming/$date.payload"
    echo "File Recieved."
    sleep 10
./$(basename $0) && exit

client.sh

#!/bin/bash
clear
mkdir outgoing
    echo "Client Running."
        file="outgoing/payload.file"
# For Demo Only
    touch $file
    echo "Some Data" >> $file
# Set The Server IP and Port To Connect To
    echo $(nc -w 3 192.168.1.XXX 1234 < $file)
    echo "File Sent."
    sleep 60
./$(basename $0) && exit

OpenSSL Basic Encryption Script With Random Password Generation

Example script using OpenSSL AES 256 with Salt and a random generated password.
It’s the little things.

#!/bin/bash
clear
echo "Input String:"
    read input
        pass=$(echo cat /dev/urandom | tr -dc 'a-zA-Z0-9' | fold -w 1024 | head -n 1)
        encrypt="$(echo -e $input | openssl aes-256-cbc -pbkdf2 -iter 20000 -salt -a -e -k $pass)"
        decrypt="$(echo -e $encrypt | openssl aes-256-cbc -pbkdf2 -iter 20000 -salt -a -d -k $pass)"
    echo -e "Encrypted String: "$encrypt
    echo -e "Decrypted String: "$decrypt
    echo "Hit Any Key.."
  read anykey

Port Scanner Using Bash and Nmap

Port Scanner Using Bash Netcat Nmap

A simple and easy to use port scanner that allows the user to input a URL or IP Address and Port Range to scan using Netcat and Nmap and also works exceptionally well with proxychains.

#!/bin/bash
date="$(date +%y-%m-%d_%H:%M:%S)"
log="$date.log"
touch $log
clear
    echo "Enter URL:"
     read url
    echo "Start Port:"
     read Sport
    echo "End Port:"
     read Eport
clear
    port=0
        while [ $port -lt $Eport ]; do
        nc -z -v $url $port 2>&1 | grep succeeded && echo $port >> $log
        let port=port+1 
    done
        while IFS= read -r openport
    do
        clear
        echo "Scanning $url - CTRL C to Abort"
        nmap -p $openport $url >> $url.txt
    sleep 5
    clear
done < $log
rm $log
BashKat Web Scraper

BashKat Web Scraping Utility Script

BashKat is pretty straight forward and really easy to use.
I made sure to add some “cute” to it with the emojis.
This bot will scrape from user input or a file using the wget function (example: urls.txt) and it’s Super Fun when using Proxychains.
