[prelude-user] Connexion problem between Snort and prelude-manager

[ScottO]

Hi Sylvain,

If you are in fact trying to connect to a remote Prelude Manager, then on
your Snort box you need to specify the right address.  In the client.conf,
default location is: /usr/local/etc/prelude/default/client.conf, you would
set the server-addr to be the address of your remote manager.

Then restart Snort.
