Here is a free tool that will replay actual traffic:
http://www.anzen.com/research/nidsbench/tcpreplay.html
It replays information from tcpdump.
If you want to make a TCP/IP packet from scratch try nemesis. It is billed
as " Command line driven portable IP stack." It supports TCP, UDP, ICMP,
ARP, IGMP, DNS, RIP, and OSPF.
