The command sounds like this: /usr/sbin/conntrack -D --p udp --orig-src 202.x.x.47 --orig-port-src 14276 --orig-dst 202.x.x.155 --orig-port-dst 20000 --reply-src 202.x.x.89 --reply-port-src 28246 --reply-dst 202.x.x.155 --reply-port-dst 20002 but, I think that there's no bug. Simply there's no conntrack entry. Error: NFNETLINK answers: No such file or directory Error: Operation failed: such conntrack doesn't exist No contrack entry where found on from->to way trying to->from I think that don't came packets that match with the iptables rule and conntrack was not created. And can't be deleted. I will search for bug in the application. Thanks Pablo. Adelson On Fri, Jun 20, 2008 at 8:43 AM, Pablo Neira Ayuso <pablo@xxxxxxxxxxxxx> wrote: > Adelson O.
