Hi Gurus,

I just install Snort 1.81 (Version 1.8.1-RELEASE (Build 74))couple days ago,
I used it to analysis the data I collected from tcpdump (sniffing @

I also download the latest ruleset from sourcefire. Since I am just testing
this product, and my tcpdump -w output is very small, so I just used the
default ruleset from snort --at the end of snort.conf (include sql.rules
include x11.rules
include icmp.rules
include shellcode.rules
include misc.rules
include policy.rules
include info.rules
include icmp-info.rules
include virus.rules
include local.rules)

However, everytime I use snort -r to read the tcpdump -w output, and I get
#snort received signal 3, exiting ALL THE TIME.. so i can't tell the
integrity of the output.

I am running snort on Solaris7sparc(64bit) 300Mhz, 4Gb, 128Mb , and that sun
box is not running anything else except snort...I can't see what's wrong..

Here's the actual output.. Any help is apperciated!!!!  thx in advance
