This project reached its End Of Life in 2002
Lcrzo was renamed netwib starting from version 5.


Lcrzo is a network library, for network administrators and network hackers.
Its objective is to easily create network programs. This library provides network functionnalities for Ethernet, IP, UDP, TCP, ICMP, ARP and RARP protocols. It supports spoofing, sniffing, client and server creation. Furthermore, lcrzo contains high level functions dealing with data storage and handling. Using all these functions, you can quickly create a network test program.

The library lcrzo provides :
  + network functionnalities :
    - address conversion
    - packet encoding/decoding/printing
    - spoofing
    - real/virtual UDP/TCP clients/servers
    - sniffing
    - device(network board) dealing
    - etc.
  + and general functionnalities :
    - data conversion
    - chained list
    - IPC
    - etc.

Lcrzo was successfully installed under Linux, Windows, FreeBSD, OpenBSD and Solaris.

Over 400 usage examples of lcrzo are included in lcrzoex.
