Hi guys, I just wanted to know what is the size limit of a bpf filter file. Currently, I'm using one with about 125 lines (meaning 125 simple expressions like !(src host xxx && dst host yyyy)) and addind one more line (expression) makes snort fail although the rules are ok: pfring DAQ configured to passive. Acquiring network traffic from "eth2". ERROR: Can't set DAQ BPF filter to ' I didnt find any clear information about what could impact bpf file size. Some buffer allocation ? Any help would be greatly appreciated. Thanks Dan
