TRIPP

An IP options handler, a virtual clock for TCP timestamps, a packet delayer, a packet marker, the ability to match packets randomly, the ability to limit rewriting to a specific host only, the ability to pass rules directly via the command line, and the ability to set a payload for empty packets were added. A bug that prevented payload rewriting on little endian systems from working correctly, a routing problem on BSD systems, an endianess bug with payload rewriting, some parser bugs, an IP broadcast bug, and many OpenBSD problems were fixed.

A rewriter for incoming traffic, the ability to
preserve the original tcp_options values,
fragments sorting support, a fake ARP daemon, raw
IP support, a print action, and multithreading
were added. A bug in the tcp_options handler, some
parsing bugs, and a bug in fragment offset
calculation were corrected.
