Thank you for desk checking this. All ways better to have a second pair
of eyes looking things over.
I made the changes you suggested and like you though it made no
difference. The script permissions are correct. If they were not, the
single record would not have processed.
I issued "ps ax" and I don't see the ipf.table script running.
I made this simple change to the ipf.table script;
while read line; do
echo "$line" >> /var/log/ipf.table.log
Now the "ps ax" command shows it running and the /var/log/ipf.table.log
file has the same content as the /var/log/security file. So its working
like I wanted. Don't understand why, but thats ok.
Thanks for your help.
