Logging in /var/log/messages????  YOu may not want to do that. I log in /var/log/sensorname/snort/    Also is your NIC card working ok?   and what machine specs?

I am logging snort in the /var/log/messages and also on a remote security information management system like netforensics.
I can see some http insepct preprocessor messages but i know its missing out on a lot of them.
below si the tcpdump output.
 
 
this is what i see when i do tcpdump
 
#tcpdump -i eth1

tcpdump: WARNING: eth1: no IPv4 address assigned
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on eth1, link-type EN10MB (Ethernet), capture size 96 bytes

1 packets captured
670 packets received by filter
622 packets dropped by kernel

Hi all,
 
I am runnning snort on a fedora box and i started with a doubt that it is not logging all the packets.
I checked it with tcp dump and when i stop tcpdump i see 90% of the packets being dropped by the kernel.
When i see /var/log/messages 
i see the below error for both sniffing interfaces
 
OpenPcap() device eth0 network lookup:  ^Ieth0: no IPv4 address assigned
 
I checked the version of libpcap running it is
 " libpcap-0.8.3-3 "
Output of # uname -a  

Linux localhost.localdomain 2.6.5-1.358smp #1 SMP Sat May 8 09:25:36 EDT 2004 i686 i686 i386 GNU/Linux
 
If anybody could help me on this i would really appreciate it.
thanks all,
kaps
