Using RH-E-WS-4 that has kernel-2.6.9-5.EL, I downloaded and installed iptables-1.3.1 and wrote a test program to use: iptables -A OUTPUT -p icmp -j QUEUE It stops on ipq_read without detecting pings that I send it. Does anyone have any knowledge of this? I could send the test program if anyone wants to see it. It follows resommendations given in man libipq. Thanks for your advice. Mike -- Michael D.
