Pfstat trouble, no data in database file

[Lars Wittebrood]

Hello list,

I've installed and configure the Pfstat port on a FreeBSD 6.1 RELEASE
system acting as a firewall based on PF.

FreeBSD servername 6.1-RELEASE-p10 FreeBSD 6.1-RELEASE-p10 #0: Fri Nov
24 13:33:18 CET 2006     root at servername:/usr/obj/usr/src/sys/ALPHA
i386

The trouble I have is that I get no data at all in the Pfstat data file!

My Pfstat /etc/crontab entries
#
# Gather Pfstat output continually
*       *       *       *       *       root    /usr/local/bin/pfstat -q
>> /var/db/pfstat.db
#
# Generate Pfstat graphs every 5 minutes
*/5     *       *       *       *       root    /usr/local/bin/pfstat -c
/etc/pfstat.conf -d /var/db/pfstat.db
#
# Glean old Pfstat data
1       1       1       *       *       root    /usr/local/bin/pfstat -t

Entries from my cron log:

As you can see pfstat.db stays zero bytes! Anyone any idea why this is
happening? My /etc/pf.conf has a set loginterface entry!

MTIA.

Cheers,
