[Snort-users] snort alerts

Hi all,

I am pretty new to snort and trying to get an grip on
how it works.

My set up is a laptop running snort 21 and an
application client connecting to a server. I think i
configured the attached snort.conf to alert and log to
mysql any activity on port 80 (either way) and on
other ports that were listed from netstat -a.

When i start up snort i get a signature, tcphdr etc.
written out on port 80 but as i use the application
nothing gets registered. It is possible my application
is using a different port and i am not montoring that
port, but i'd think if i spanned all ports given by
netstat at that point in time, snort should be able to
pick up activity of my application. I would expect
that all application client related traffic would be
sent to my laptop

Please find below the "redalert" section of my
snort.conf. Only thing that registers (logged) is App
15.

Appreciate any help.
