In fact, I have used scapy in the past, but I am working in a restricted environment and don't have this package available. It provides tones more than I really need anyway, and I figured a simple raw socket send/receive can't be *that* hard. I may have to reverse engineer some C code, such as dhclient...

That's why I was asking about how to do raw sockets, since tools like dhclient use raw sockets to do what they do. It can clearly be duplicated in Python, I just need to find some code samples on how to construct a raw packet.
