Omar Herrera - -----Original Message----- From: Ingersoll, Jared [mailto:jaredat_private] Sent: Lunes, 04 de Noviembre de 2002 03:28 p.m. To: incidentsat_private Subject: Ip spoof from 0.0.0.0 I was hoping someone could tell me whether this is a misconfigured device (perhaps) or is this activity I should be concerned with (and please keep any witless banter regarding my use of 'concerned with' to yourself- thanks!). These are SYSLOG entries from my firewall (PIX).
