question on libnetfilter_conntrack

Hi all,

I use api provided by libnetfilter_conntrack library. When
creating conntrack (nfct_conntrack_alloc) record I assign it
an id. Then conntrack is successfully created
(nfct_create_conntrack). However, when I try to delete it
later on using the same id call (nfct_delete_conntrack)
fails (NFNETLINK answers: No such file or directory). If I
look at conntrack using "conntrack -L -i" I see
that created record has another id than I assigned it in
nfct_conntrack_alloc.

Does libnetfilter_conntrack ignore given id? If not, what
can be wrong?

Configuration:
Linux debian, kernel 2.6.20.8
libnetfilter_conntrack 0.0.31

thanks for answers

This version is really from the cavemen era. Please upgrade
to 0.0.80
and check the new API (see utils/ example files).
