You need to do what I do. I almost exclusively use ACID to monitor my snort
data. It does the DNS lookups for you, so if your site does DDNS, you're

If it doesn't, and you want WINS lookups, then ACID is pretty easy to edit.
Edit acid_stat_ipaddr.php and href a CGI doing WINS lookups in a similar way
to the WHOIS lookup ACID already does.
