Iptables

-

Although there is more abstract software to manage firewalls, like ufw on debian-based systems and firewall-cmd on redhat systems, Iptables will help you understand what actually happens during filtering, mangling or routing a package. https://www.frozentux.net/iptables-tutorial/iptables-tutorial.html has a structured approach in explaining what happends when a package hits the firewall. +

Netcat

+

Simple tool to open or connect to TCP or UDP ports and output data through these channels. Build and test proxies. Powerful for debugging. Cryptcat is a similar tool, but with support for cryptography +

+

Sendip

+

Create and send IP, TCP or UDP packages. You are able to edit any value within these packages. +
