G'day I asked the same question with the difference being that I use postgres. The answer will work just the same though. Thanks again Roberto, it's now in daily use...:-) Ooroo Mark F... On Oct/22/2001, Mark Forsyth wrote:
Hiya, Maybe I've lost the plot completely but.. Snort stores IP addresses ( Ip_src & ip_dst ) in the iphdr table as a bigint so a select of that table returns ...:-
As I parse the data from the DB with Perl, I made a quick dirty function to parse a bigint into a "normal" IP address. Maybe it's useful :-) sub bigint2ip ($) { my $bigint = shift; my $ip = ""; my $tmp = $bigint; for (my $i=32; $i > 0; $i-=8) { $ip = ($tmp & 255) . ".$ip"; $tmp = $tmp >> 8; } chop($ip); return $ip; } I guess it's trivial to "port" it to any another language. But I'm also sure that there are better ways to do it :-) -- Roberto Suarez Soto Alfa21 Outsourcing robe () alfa21 com http://www.alfa21.com On Thursday, November 01, 2001 3:36 PM, Jason Straight [SMTP:jason () blazeconnect net] wrote:
I'm confused. Snort on mysql has an ip addy that's nothing more than an integer. How do I get a dotted quad IP# from: 208436227 ? Thanks in advance. -- Jeet Kune Do does not beat around the bush.
