Sending a SIGUSR1 to the snort process causes it to write some interesting statistics to the system log file. Under the "Breakdown by protocol:" column, I find that about 4% of my traffic falls under "other". What is this? Is there a way (using snort) to log or view it?
One way would be to include a restrictive bpf filter '(tcp or udp or icmp)' that would cause libpcap to pass tcp or udp or icmp to the alert detector in snort. In a separate process you could run tcpdump using a filter 'not (tcp or udp or icmp)'. Then you would at least know what other protocols were being used on your network. There is the "ip" alert/log syntax which I have not used. Maybe that is a way to get what you want. Sorry, that's all I got. Off to a meeting. Bye
(As an aside, on my Solaris 8 sensor, sending 2 successive SIGUSR1s to snort will cause the process to abort.) Thanks in advance. Benny
