Re: IP Addresses in Database tables

There are currently 10 fields which are used to redundently represent IP address in the "iphdr" table. "ip_src, ip_dst": the 32-bit unsigned integer representation of the IP address (I believe this is what you mean by "hashes". Use bit operations to extract an IP address in dotted notation Assume: a.b.c.d a = (ip_src AND FF000000) >> 24 b = (ip_src AND 00FF0000) >> 16 c = (ip_src AND 0000FF00) >> 8 d = (ip_src AND 000000FF) ) ip_src0, ... ip_src3; ip_dst0 .. ip_dst3: 4 octets of the IP address. ( source address = ip_src0 . ip_src1 . ip_src2 . ip_src3 ) Please note that in future versions of the database plug-in, the 4 octet representation will be removed. cheers, Roman
How are IP addresses "hash" when they are insert into a database. I have snort logging to Oracle and I want to decode the IP address that I see in the table. _______________________________________________ Snort-users mailing list Snort-users () lists sourceforge net Go to this URL to change user options or unsubscribe: http://lists.sourceforge.net/lists/listinfo/snort-users Snort-users list archive: http://www.geocrawler.com/redir-sf.php3?list=snort-users
