Setting Up a Pentesting Lab with ISC DHCP Server

#!/bin/bash

# In Kali Linux

# 1. First, set a static IP for your Kali interface
ip addr add 192.168.1.1/24 dev eth0  # Adjust interface name as needed

# 2. Configure dhcpd.conf
cat << EOF > /etc/dhcp/dhcpd.conf
default-lease-time 600;
max-lease-time 7200;

subnet 192.168.1.0 netmask 255.255.255.0 {
  range 192.168.1.100 192.168.1.200;
  option routers 192.168.1.1;
  option domain-name-servers 192.168.1.1;
}
EOF

# 3. Configure dhcpd to listen on the correct interface
echo "INTERFACESv4=\"eth0\"" > /etc/default/isc-dhcp-server

# 4. Start the service
systemctl restart isc-dhcp-server
