Hi
I am developping an application using libnetfilter_conntrack
I first tried to run the example program ctnl_test, it seems to work
for events and table dumping but i still get errors and i would like
to know if it's normal
Here is the output :
Test for libnetfilter_conntrack
NFNETLINK answers: Invalid argument
TEST 1: create conntrack (-22)
NFNETLINK answers: -EINVAL, make sure ip_conntrack_netlink is loaded
and you have NET_CAPABILITIES
TEST 2: dump conntrack table and reset (-524)

Test failed with error -1. Errors=5
I'm using a 2.6.15 kernel and i have all the needed modules
installed(ip_conntrack_netlink, ip_conntrack, nfnetlink,
nfnetlink_log...)
Thanks

No, it is not a normal output. What version of libnetfilter_conntrack
are you using?
