Hello, I've installed (from scratch) kernel 2.6.16.4, iptables 1.3.5 libnetfilter_conntrack-0.0.30, conntrack-1.00beta1.tar.bz2 libnfnetlink-0.0.14.tar.bz2. Now when I'm typing "conntrack -L " it returns error: "Operation failed: invalid parameters" Is there a way to determine what causing this behavior ? Thanks for any clues Regards Pawel Pilat
