hping is a command-line oriented TCP/IP packet assembler/analyzer. The interface is inspired to the ping(8) unix command, but hping isn't only able to send ICMP echo requests.

It supports TCP, UDP, ICMP and RAW-IP protocols, has a traceroute mode, the ability to send files between a covered channel, and many other features.

Here are some key features of "hping":
Firewall testing
Advanced port scanning
Network testing, using different protocols, TOS, fragmentation
Manual path MTU discovery
Advanced traceroute, under all the supported protocols
Remote OS fingerprinting
Remote uptime guessing
TCP/IP stacks auditing
hping can also be useful to students that are learning TCP/IP.

Scan mode. You can use hping as a low-level automated TCP port scanner. An example of output follows
