libdnet provides a simplified, portable interface to several low-level networking routines, including

• network address manipulation
• kernel arp(4) cache and route(4) table lookup and manipulation
• network firewalling (IP filter, ipfw, ipchains, pf, PktFilter, ...)
• network interface lookup and manipulation
• IP tunnelling (BSD/Linux tun, Universal TUN/TAP device)
• raw IP packet and Ethernet frame transmission

Supported languages:

• C, C++
• Python
• Perl, Ruby (see below)

Supported platforms:

• BSD (OpenBSD, FreeBSD, NetBSD, BSD/OS)
• Linux (Redhat, Debian, Slackware, etc.)
• MacOS X
• Windows (NT/2000/XP)
• Solaris
• IRIX
• HP-UX
• Tru64

Builds cleanly on, but needs work - see TODO: (please let me know if you have access to these systems!)

• AIX
• UnixWare
