uhmm, ok.
I'd like to check it first on any socket, do you know any network programms
(aplications, benchmarks etc) to open sockets with debug option, or give a
'-'switch to do that?
trpt on my system keeps on saying :

% trpt: /boot/kernel/kernel: no namelist

so probably no sockets are currently SO_DEBUG ready.
