Re: confuse with alerts file

[maku bex <maku_bexs () yahoo com>]

thx for replying...
the scenario is i have a one box installed with
snort..
and i'm trying to deploy the snort into another box as
well, the configuration is same
[snort.conf]
[Unix flavours should use this format...]
output alert_syslog: LOG_AUTH LOG_ALERT
output database: log, mysql,

for both snort i run with this command
snort -qbID -i eth0 -c /etc/snort/snort.conf -u snort
-g snort m 007

for box one....its generates the alert file....
tail -f /var/log/snort/alert

Sep 29 09:53:00 src@marc-sguard snort: [1:2000328:3]

BLEEDING-EDGE Multiple Non-SMTP Server Emails
[Classification: Misc activity] [Priority: 3]: <eth0>
{TCP} x.x.x.x:1144 -> x.x.x.74:25

But for the second one....like i said...no alert file
in /var/log/snort/, which is i dont quite understand
here...i guest the snort is not running......so i tail
the messages log 

ping www.google.com
tail -f /var/log/messages
it gives me the output:
Sep 29 10:48:21 vmware snort: Warning: flowbits key
'tls1.server_hello.request' is checked but not ever
set.
Sep 29 10:48:21 vmware snort: Warning: flowbits key
'tls.client_hello.request' is checked but not ever
set.
Sep 29 10:48:22 vmware snort: Snort initialization

<eth0> {ICMP} 216.239.39.99 -> 192.168.0.35

any ideas..?
