Syslog: logger xferlog

xferlog can be filtered then written into syslog with the utility 'logger'. Here's a script with check_log style. Column 8 and 15 is the ip / id pair:

xferlog=/var/log/proftpd/xferlog

if [ ! -f ${xferlog}.old ]; then
 cp $xferlog ${xferlog}.old
fi

diff $xferlog ${xferlog}.old | grep "<" | awk '{print $8 " " $15}' | while read LINE
do
logger $LINE
done

rm -rf ${xferlog}.old
cp $xferlog ${xferlog}.old
