[ snip ] "C" is close. Not sure what you mean by "a ton of interfaces". Most (all?) good managed switches have a "monitor port" or "mirror port" where they can blind copy traffic from other ports to the one that's set aside for snooping. Four-port ethernet cards are readily available. How many switches do you wish to monitor simultaneously? Even with only four ports (more in one box is certainly possible), you can have a fair amount of traffic to digest. -- Eddy Brotsman & Dreger, Inc. - EverQuick Internet Division Phone: +1 (316) 794-8922 Wichita/(Inter)national Phone: +1 (785) 865-5885 Lawrence -- Date: Mon, 21 May 2001 11:23:58 +0000 (GMT) From: A Trap <[EMAIL PROTECTED]> To: [EMAIL PROTECTED] Subject: Please ignore this portion of my mail signature.
