You could also just copy the stunnel.log file to a linux system to
do the processing, or perhaps use windows unix/linux commands.
Modified version that now will actually add the name to each line
Added filtering out 127.0.0 and 192.168 changes and now creates
the file stunnelx.org that will have all the additions. Does end up
with the :port afterwards, but that is minor.
First line does wrap.
============
grep -Eo '([0-9]{1,3}\.){3}[0-9]{1,3}' /var/log/stunnel.log | sort | uniq
| grep -v 127.0.0 | grep -v 192.168. >stout
echo -n "" >stout2
echo -n "" >stout2x
for a in `cat stout` ; do
echo -n $a " ">>stout2;
echo -n "s/"$a"/"$a" " >>stout2x;
host $a | awk '{print $5}' >>stout2;
host $a | awk '{print $5"/g"}' >>stout2x;
done
sed -f stout2x /var/log/stunnel.log >stunnelx.log
