Ok .... It is finally producing alert.csv but only when I dont use -A flag
as you mentioned.
Thanks for this tip Jason.
Happily, I wish you had tried it earlier.
But what is going wrong? Why does snort log alerts in tcpdump and other
formats with -A flag but not with csv? Do I need to set my path somewhere?
Absolutely nothing is wrong, it is clearly noted in the manual that
command line options override config options.
Your output for tcpdump is a log output, for csv it is an alert output,
-A console (Alert to console) overrides and alerts to console as you
requested.

Yes - all other outputs i.e. tcpdump, fast, standard are working
properly.
Its only csv that is not producing any output.
Possibly. Paste your conf to http://snort.pastebin.com and the entire
output of running the command snort -l /tmp -i lo -c test.conf
Thanks for pointing to the Snort development site.
Apologies for posting to private e-mail unintentionally.
Come on guys, is there anyone to point out where I might have
problem??????

Hi Jason,
Thanks for the reply. However, due to my ignorance I couldn't get much
out
of it.
inline -- could you please elobarate more.
Perhaps it is because command line options override the config file.
I don't really think so, because the tcpdump output is working without
any
glitches.
Did you try?
You will have to write the code to make packet data available in the
csv.
I guessed so -- can you provide any useful links, where to start from
and
which module/preprocessor to modify??
You should start reading here - http://www.snort.org/docs/#devel
Specifically, look at src/output-plugins/spo_csv.c
For templates check out hte sources in the templates directories.
Please keep replies on list, it doesn't much help the next person when
things go off-line.

Hi All,
I am new to Snort and this is my first mail to this list so please
bear
with
me.
First - I have been trying hard for last few days to get csv plug-in
work
for me but it has not. I am on Fedora Core 7 and running Snort
2.8.1the
latest version. I am running Snort with the following command:
snort -A console -i lo -c test.conf (please see the output of
running
this
command at the bottom of this mail)
I have enabled only one rules file i.e. local.rules and have some
test
rules
in it.
the entry for my csv output plug-in in the test.conf file is
output alert_CSV: /var/log/alert.csv default
Afterwards I generate some attack traffic and get some alerts on the
console. (please see the output at the end of this mail).
The problem is that the alert.csv is never created!!!
I have tried using full mode, -h flag and few other tricks but
nothing
is
working
Perhaps it is because command line options override the config file.
Please note that I have not installed barnyard and assume that it is
not
a
must for csv module to work.
My second question is the following:
If I am lucky enough to configure the csv module correctly with the
help
of
you gurus, then how can I extend this module to add more details
about
the
packet payload to the csv output ?
I have posted similar messages on Snort forum without any response.
Any
help
is appreciated.
You will have to write the code to make packet data available in the
csv.
