Hi All,

Sorry for the confusion. Let me just clarify myself.  I know how to
install
Snort and Snorby on the same server and configure them to work together
but
right now, I need to use Snorby on my server to fetch the alerts from 3
different remote servers that have Snort installed on each of them. I
was hoping
if you could provide me a step by step instruction or direct me to a
suitable
guide for the same.

i cannot direct you to any guides or explain how to do it but the general
idea
is this...


1. install snort on a sensor in each network you need to monitor.

2. install a tool like barnyard2 on each sensor.

3. setup a central database somewhere for all sensors to report to.

4. configure each snort with a specific identifier to keep alerts
separated by
sensor in the central database. (see the -G and -logid command line
parameters)

5. configure each tool like barnyard2 to gather the alerts and insert them
into
the central database.

6. use whatever tool you like (snorby??) to monitor the alerts in the
central
database.


the basic gist is that each sensor pushes its alerts to the central
database
where all the monitoring is being done... effectively, once you install one
snort/barnyard2 combination, you duplicate it to all other sensors giving
each
sensor an id number via the -G command line option... then each sensor's
barnyard2 will push the sensor's alerts to the central database and you
can use
whatever tool you like to monitor the database...
