RE: Multiple Subnets in sr net

["Jeff Dell" <jdell () activeworx com>]

Snort uses Berkley Packet Filters.. To do this try the following:

$SNORT_PATH/snort -c $CONFIG -i $IFACE -g $SNORT_GID $OPTIONS src net
10.1.1.0/24 or src net 10.2.1.0/24

Cheers,

Jeff

I am not specifying it in HOME_NET. I want snort to monitor the whole
network and sent alerts only for specific subnets. Hence i add the option
src net in the snort script as

$SNORT_PATH/snort -c $CONFIG -i $IFACE -g $SNORT_GID $OPTIONS src net
10.1.1.0/24

My question is how to add the second subnet 10.1.2.0/24 in this.

Cheers

Sure, here is an example on how you can do this:

var HOME_NET [10.1.1.0/24,10.2.1.0/24]

Note: There is not a space between subnets.

Hi,

  Can multiple ip subnets be given in the src net option in snort. I have
snort monitoring the whole 10.0.0.0/8 network and i want snort alerts from
10.1.1.0/24 and 10.2..1.0/24 .

Cheers
