Hi all, I am trying to run 2 program to use ip_queue module at the same time. I basically start the first program and it runs fine receiving packets correctly. I then run the second program, which prints the following error: "Received error message 16" and keeps running without receiving any packets! The two programs that I am running are snort inline and my code based on the sample which comes with libipq(3). Both programs runs fine when run alone. I only get this problem when I try to run them together. My question: does libipq module support more than one program at one time? is there any options I should set when modprobe ip_queue? thank u for ur help, ahamd __________________________________ Do you Yahoo!?
