pflog
— packet
filter logging interface
pseudo-device pflog
The pflog
interface is a pseudo-device
which makes visible all packets logged by the packet filter. Logged packets
can easily be monitored in real time by invoking
tcpdump(1) on the
pflog
interface.
Instances of the pflog
interface can be
created using ifconfig(8).
Create a pflog
interface and monitor all
packets logged on it:
# ifconfig pflog1 create # tcpdump -n -e -ttt -i pflog1
inet(4), inet6(4), netintro(4), pf(4), ifconfig(8), tcpdump(1)
The pflog
device first appeared in
OpenBSD 3.0.
