PCAP-FILTER(5) - File Formats Manual # PCAP-FILTER(5) - File Formats Manual NAME # pcap-filter - packet filter syntax DESCRIPTION # pcap_compile(3) compiles pcap filters for software such as tcpdump(8). The resulting filter program can then be applied to some stream of packets to determine which packets will be supplied to pcap_loop(3), pcap_dispatch(3), pcap_next(3), or pcap_next_ex(3). The filter expression consists of one or more primitives. Primitives usually consist of an id (name or number) preceded by one or more qualifiers. ...

PFLOGD(8) - System Manager’s Manual # PFLOGD(8) - System Manager’s Manual NAME # pflogd - packet filter logging daemon SYNOPSIS # pflogd [-Dx] [-d delay] [-f filename] [-i interface] [-s snaplen] [expression] DESCRIPTION # pflogd is a background daemon which reads packets logged by pf(4) to a pflog(4) interface, normally pflog0, and writes the packets to a logfile (normally /var/log/pflog) in tcpdump(8) binary format. These logs can be reviewed later using the -r option of tcpdump(8), hopefully offline in case there are bugs in the packet parsing code of tcpdump(8). ...
