Ahh..netcat..how useful you are to me! If you don’t use netcat for pen testing you absolutly have to. Good article below on how you can use netcat. Some examples:
* 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
* Ability to use any locally-configured network source address
* Built-in port-scanning capabilities, with randomizer
* Built-in loose source-routing capability
* Can read command line arguments from standard input
* Slow-send mode, one line every N seconds
* Optional ability to let another program service inbound connections
