Advanced libnet Functions

Libnet is an open source software library that provides a simple interface for constructing and sending network packets. It is commonly used by network security professionals and developers to create custom network tools and utilities.

Advanced libnet functions refer to the more complex features available within the library that allow for greater control over packet construction and transmission. These functions include:

Packet Fragmentation: Advanced libnet functions allow for the fragmentation of packets, which can be useful for evading network detection systems that may only inspect the first few bytes of a packet.
IP Options: Libnet supports the addition of IP options to packets, which can be used for things like specifying a particular route for the packet or indicating a higher priority for the packet.
Protocol Headers: Libnet allows for the creation of custom protocol headers, which can be used to create new protocols or modify existing ones.
Packet Filtering: Libnet can be used in conjunction with libpcap to create packet filtering and monitoring tools.
Custom Payloads: Advanced libnet functions allow for the creation of custom payloads, which can be useful for testing the security of networked applications.

Overall, advanced libnet functions provide a powerful set of tools for network security professionals and developers to create custom network tools and utilities.
