Hi. I was asked (off-list) to provide some additional informations, esp. the packet counters from the OS. debian3164m:~# netstat -ni Kernel Interface table Iface MTU Met RX-OK RX-ERR RX-DRP RX-OVR TX-OK TX-ERR TX-DRP TX-OVR Flg eth0 1500 0 413593 0 0 0 287444 0 0 0 ABMRU lo 16436 0 78789 0 0 0 78789 0 0 0 LRU [... several hours later ...] debian3164m:~# netstat -ni ; pkill snort Kernel Interface table Iface MTU Met RX-OK RX-ERR RX-DRP RX-OVR TX-OK TX-ERR TX-DRP TX-OVR Flg eth0 1500 0 424152 0 0 0 289605 0 0 0 ABMRU lo 16436 0 84348 0 0 0 84348 0 0 0 LRU I am snorting on eth0 (non promiscous). So after 12720 packets (10559 receiving and 2161 transmitting) I killed snort and as packet statistics it gave: Snort ran for 0 Days 12 Hours 10 Minutes 16 Seconds Packet analysis time averages: Snort Analyzed 30 Packets Per Hour Snort Analyzed 0 Packets Per Minute Snort Analyzed 0 Packets Per Second Snort received 367 packets Analyzed: 12715(3464.577%) Dropped: 0(0.000%) Outstanding: 4294954948(5026360781529153536.000%) =============================================================================== Breakdown by protocol: TCP: 3799 (29.878%) UDP: 736 (5.788%) ICMP: 189 (1.486%) ARP: 7991 (62.847%) EAPOL: 0 (0.000%) IPv6: 0 (0.000%) ETHLOOP: 0 (0.000%) IPX: 0 (0.000%) FRAG: 0 (0.000%) OTHER: 0 (0.000%) DISCARD: 0 (0.000%) =============================================================================== Action Stats: ALERTS: 20 LOGGED: 20 PASSED: 0 =============================================================================== TCP Stream Reassembly Stats: TCP Packets Used: 3799 (29.878%) Stream Trackers: 164 Stream flushes: 619 Segments used: 1395 Segments Queued: 1397 Stream4 Memory Faults: 0 =============================================================================== Snort exiting This weird number also occur if I request this statistics via SIGUSR1. And again I will get a reasonable number of outstanding (whats are outstanding packets ?) if I subtract the snorts number of outstanding packets from 2^32 (2**32 - 4294954948 = 12348). Any hints/clues ? Thanks, Andreas. P.S.: Of course I will try the fresh and shiny new snort released yesterday. ------------------------------------------------------------------------- Take Surveys.
