Re: Fatal error when starting snort on the sensor

The duplicate classification is not a fatal error, but my guess is that somewhere, somehow, you are including classification.config twice. Look through your snort.conf and make sure it's only listed once. The fatal error is that your EXTERNAL_NET variable is not defined. Defining HOME_NET and EXTERNAL_NET is one of the first things you are supposed to do when editing snort.conf (have you read through the comments???). Usually, you define HOME_NET as the networks you are monitoring, and EXTERNAL_NET is defined as everything else (!$HOME_NET) HTH On Sat, 18 Sep 2004 00:58:36 +0300, Juan Fernandez <juan.fernandez () deltathree com> wrote:
