Reading pflog file in FreeBSD

Written by

You can enable the logging in pflog

nano /etc/rc.d/pflog

/sbin/pflogd restart

You can verify your pflogd service running :

 ps ax | grep pflogd

But this log file is binary and you won’t be able to tail it with the ‘clog’ utility in FreeBSD . To clog this file you need to use the tcpdump:

tcpdump -netttr /var/log/pflog

You can thhen filter this with your host IP , port number etc .
