net-tools

a simple bash script to check network connectivity and set various other network things nothing special just to make things a little eaiser becasue im lazy

This is still a work in progress so may be a bit rough around the edges

Features

• Set Static IP
• Set DHCP IP
• Set Default
• Set nameserver
• Add entries to hosts file
• net-check - checks connectivity - arp,ping,dns,portscan,curl
• Speedtest - using speedtest-cli
• Find public IP
• Block IPv4 and IPv6 addresss using iptables,arptables and ip6tables
• Display iptables
• flush iptables
• Set Proxy Settings
• Clear Proxy Settings

Install

Tried to make it easy use the oneliner to install the script and add it to bashrc

cd /tools
git clone https://github.com/shifty0g/net-tools/
cd net-tools
chmod +x net-tools.sh 
source net-tools.sh
net-tools-install

then add the realpath to the file into your bashrc or zshrc something like

echo "source $(realpath net-tools.sh)" >> /root/.zshrc

you should then be able to run the functions straing from your shell

Usege

once installed you can run the functions shown below from your shell

net-help 
               __              __                .__
