#Comments in this file _must_ start with a pound symbol as the far left character - they cannot be on the same line as filter items.
#To use this filter in a libpcap application, place the following where you'd normally put the filter, such as:
#tcpdump ...... "$(grep -v '^#' $HOME/med/bpf/global-ignore.commented.bpf)"
#pcap_stats.py ...... -b "$(grep -v '^#' $HOME/med/bpf/global-ignore.commented.bpf)"
#You can add other filters to it like:
#tcpdump ...... "$(grep -v '^#' $HOME/med/bpf/global-ignore.commented.bpf) and (not tcp port 80) and (not host 8.8.8.8)"
#If you like having it all on one line, use:
#tcpdump ...... "$(grep -v '^#' $HOME/med/bpf/global-ignore.commented.bpf | tr -d '\r\n')"
#
#The following lines are examples of filters.  They're not intended to be a complete filter file.
