Since I started using Snort 1.9.0, I get a massive amount of these alerts. In fact it makes the /var/log/snort/alert file grow to 2.0G within hours at which time Snort (of course) dies. Pardon my lack of knowledge, but what the heck is this alert? The 2 machines involved are a Windows XP PC (source) and a Win2k PC (destination) . I realize these are SNMP port numbers, but can someone explain the alert to me? I can easily disable SNMP on the offending machine, but I would like to learn from this.
