I run Red Hat 8.0 and I d/l the gcc version of the client. I can run the program and send data to the server but I cannot get an acknowledgement back. The firewall is not the problem because
1. the rules do not reject packets addressed to port 1026;
2. if I include a rule to accept all packets from DF server it still doesn't work
3. if I disable iptables altogether again no go.
The kernal log shows packets from 206.248.62.8 arriving but they don't get through to the program. Nor are they recorded by snort.

I am not a linux beginner but I'm not familiar with this area. Can someone please point me to a diagnostic tool that will let me track packets and find out what blocks them?
