Actually i want to construct different IP packets like (DHCP discovery, HTTP request/response,...) and send it to servers so that i can simulate a protocol client to a certain extent..(for ex. for dhcp discover packet sent I am getting any dhcp reply or not).

My overall need is to send different packets(DHCP, HTTP, ARP, PING, etc..) from the program..capturing the replies(packets) for those packets if any..And i should be able to modify the captured packets and again sent back to any other host..
------------------------------------------------------------
Till now I know how to generate and send udp/tcp/icmp packets with NET::RawIP module..But I am not able to construct packets above TCP/UDP(DHCP, HTTP, etc..).
Also I need to know how to capture packets from ethernet, modify them and again send on the ethernet..
------------------------------------------------------------
thanks and regards
