To access your Kali machine from outside your local network using SSH, you need to ensure that your network and the machine are configured correctly. Here are the steps:

 sudo apt update

sudo apt install openssh-server

sudo systemctl enable ssh

sudo systemctl start ssh

curl ifconfig.me

sudo nano /etc/dhcpcd.conf

interface eth0

static ip_address=192.168.1.100/24

static routers=192.168.1.1

static domain_name_servers=192.168.1.1

sudo systemctl restart dhcpcd

ssh maverick@your_public_ip -p external_port

Ex:-

ssh maverick@203.0.113.10 -p 2222
