Hi, trpt(8) is utility to pull TCP debugging data from the kernel in 4.2BSD. We still have it in the base, with corresponding TCPDEBUG option in the kernel and SO_DEBUG socket option.
At the same time we have much more powerful debugging facilities for TCP, e.g. the Dtrace probing, the TCP black box logging and siftr. These are the tools that modern developers use. Already touched this topic with rscheff@, tuexen@, rrs@ and jtl@. None of them new what trpt(8) is :) Looks like a good justification to me. -- Gleb Smirnoff
