Ever read your IPS and firewall reports in the morning and wonder what all those IP addresses are. The linux command on the command line is nslookup.
That said, I'll be the first to admit I'm as lazy as they come and that was simply too much work, so I did a quick utility to dump the database of IP addresses, do an nslookup on them. I created a second utility to also mail it which I've cron'ed to run at midnight every day.
I've attached the files. Simply remove the .txt extensions and scp it to your untangle box.
