In the second post of the tools series, I am going to cover netcat utility. It comes prepackaged on most of the linux distributions. The netcat utility is often referred to as a Swiss army knife of networking tools. It has a long list of features. Few of them are mentioned below.
- Outbound or inbound connections, TCP or UDP, to or from any ports
- Full DNS forward/reverse checking, with appropriate warnings
- Ability to use any local source port
- Built-in port-scanning capabilities
