In my iptables: -A MDB-IN -i lo -p udp -m udp --dport 5000 -j QUEUE In my QUEUE processor, after each correctly transmitted and received udp message, I receive another signal with: ipq_message_type(buf) == NLMSG_ERROR and ipq_get_msgerr(buf) == 2 == No such file or directory I have no such problem with my other messages, which are all non-local tcp. What could cause this kind of error? Thanks in advance for your help. Mike. -- Michael D. Berger m.d.berger@xxxxxxxx
