RE: starting snort

[Juan Fernandez <Juan.Fernandez () deltathree com>]

Okey, sorry I didn't wrote enough info ( I also have read the docs):

This sensor will be in the dmz subnet when the port from the dmz switch that
goes to the firewall will be mirrored to the port that the sensor nic ( in
promisc mode ) will be in.


The second nic will be in the internal lan switch so I can manage it and
send alerts to the management server.
Is it enough info ?

Thanks

Hi,

unfortunatelly you wrote nothing about your network setup. If all the
traffic you want to observe is going over your sensor, no need to run
the nics in the promisc mode. Otherwise you even have to, but please
read the docs and older posts about running Snort on a switch or a hub.
There is a small caveat outhere.

Regards,
Edin
