Hi there!

It's seem that there is a issue with Conntrackd using a bonding as
dedicated interface.

The log:

[Thu Aug  9 14:14:23 2012] (pid=3819) [notice] -- starting in daemon mode --

Or maybe i'm missing something important in the configuration:

Any idea?

Somoething is wrong with the link state checking.

Please, get a working copy of libnfnetlink:

git clone git://git.netfilter.org/libnfnetlink
autoreconf -fi
./configure --prefix=/usr
make
make check

[no need to make install]

Then go to utils/ directory, run ./iftest and get back to the list to
report what it says.

I'm using this version (Debian amd64)

You didn't mention kernel version, I guess it is standalone Linux
kernel in Debian? (2.6.32). Using a recent Linux kernel version of the
3.x branch is really recommended to run conntrackd.

:~$ conntrackd -v
Connection tracking userspace daemon v1.2.1. Licensed under GPLv2.

BTW, it's a good idea if you upgrade to 1.2.2. There was a bug in the
commit operation that is resolved in lastest version.

This is the result of iftest:

root@debian:~/git/libnfnetlink/utils# ./iftest
index (1) is lo (RUNNING) (UP)
index (2) is eth5 (NOT RUNNING) (DOWN)
index (3) is eth2 (RUNNING) (UP)
