what is the latest status of logs from adconn? They seems to disappear in 
test testrun. That is my recollection. That is why I left the printfs there,
when I refacatored from addconn to addr_lookup.c. Now this used by pluto and 
and addconn.

What is a better way log from library function in addr_lookup.c?
