I looked into nfd.log in 3 levels(INFO, DEBUG, TRACE) but I could not find
log messages like you mentioned.
my topology was a -- b -- c -- d
and I used the following commands:

a nfdc cs config admit off
b nfdc cs config admit off
c nfdc cs config admit off
d nfdc cs config admit off
a echo "sepehr sepehr" > sepehr
a ndnputchunks ndn:/sepehr < sepehr &
a nlsrc advertise /sepehr
d ndncatchunks -d iterative ndn:/sepehr
quit

is there any specific info that I am missing?

Best,
Sepehr
