IP Injection - This is raw stuff, human!
Originally written by
- Injecting IP packets is historically done using "raw sockets".
- These sockets work at the IP protocol level:
- They see everything (coming to the machine).
- They allow creating packets (at the IP protocol level).
- Two modes of operation:
- Mode I - we let the kernel form the IP header.
- Mode II - we form the entire IP header ourselves.
