Package: tumgreyspf
Version: 1.35-7
Package tumgreyspf includes daily cron script to clean expired IPs
from database.
This script checks for GREYLISTEXPIREDAYS in
/etc/tumgreyspf/default.conf by using:
if [ -f /etc/tumgreyspf/default.conf ] ; then
GREYLISTEXPIREDAYS=`grep GREYLISTEXPIREDAYS
/etc/tumgreyspf/default.conf | cut -d'=' -f2 | awk '{print $1}' | cut
-d'.' -f1`
fi
Usually, that returns GREYLISTEXPIREDAYS value.
Unfortunately, if user experiments with different values, leaving some
of them commented, like:
#GREYLISTEXPIREDAYS = 60.0
GREYLISTEXPIREDAYS = 20.0
#GREYLISTEXPIREDAYS = 30.0
or similar, greping/cutting/awking would return:
60.0
20.0
30.0
Solution is to change a little bit command for GREYLISTEXPIREDAYS
extracting to something like:
grep ^GREYLISTEXPIREDAYS /etc/tumgreyspf/default.conf | cut -d'=' -f2
| awk '{print $1}' | cut -d'.' -f1
or, if we want to allow white spaces in front of GREYLISTEXPIREDAYS,
but not "#" character at the begining of the line:
grep -v '^#' /etc/tumgreyspf/default.conf | grep GREYLISTEXPIREDAYS |
cut -d'=' -f2 | awk '{print $1}' | cut -d'.' -f1
or, if we also want to enable whitespaces in front of comment char:
grep -v '^ *#' /etc/tumgreyspf/default.conf | grep GREYLISTEXPIREDAYS
| cut -d'=' -f2 | awk '{print $1}' | cut -d'.' -f1
then again, we can avoid returning more then one not-commented value
(if user made misconfigured default.conf, leaving more then one
GREYLISTEXPIREDAYS line uncommented) by returning just the first
value:
grep -v '^ *#' /etc/tumgreyspf/default.conf | grep GREYLISTEXPIREDAYS
| cut -d'=' -f2 | awk '{print $1; exit}' | cut -d'.' -f1
Anyways, solution is quite trivial, but can help to avoid misbehaviour
caused by choosing the wrong line containing GREYLISTEXPIREDAYS.
