Hi all,

I installed snort with the following versions:
sudo wget http://hem.bredband.net/jpgraph/jpgraph-1.27.1.tar.gz
sudo wget http://www.symmetrixtech.com/ids/snortreport-1.3.3.tar.gz sudo tar zxvf
sudo wget  wget http://www.snort.org/dl/snort-current/daq-1.1.1.tar.gz
sudo wget http://libdnet.googlecode.com/files/libdnet-1.12.tgz
sudo  wget http://www.snort.org/dl/snort-current/snort-2.9.3.tar.gz
FTP     snortrules-snapshot-2930.tar.gz

I've installed following the procedure of snort default Ubuntu 12.04
http://www.snort.org/assets/158/snortinstallguide293.pdf

The Network configuration is as follows:
2 network intefaces:
Eth0 --> IP LAN
Eth1 --> Snort

auto eth0
iface eth0 inet static
        address 192.168.252.62
        netmask 255.255.255.0
        network 192.168.252.0
        broadcast 192.168.252.255
        gateway 192.168.252.254
        # dns-* options are implemented by the resolvconf package, if installed
        dns-nameservers 172.16.14.30

auto eth1
iface eth1 inet manual
        up ifconfig eth1 0.0.0.0 up
        up ip link set eth1 promisc on
* I configured the ethernet previously not in promiscuous mode

Config int he Cisco Catalyst 3750
monitor session 1 source interface Gi0/1 , Gi0/11 , Gi0/24 , Gi0/27 , Gi0/41 , Gi0/43
monitor session 1 destination interface Gi0/44

I tested with tcpdump, and see traffic on eth1, I have also connected a wireshark and I see traffic.

Just install the snort, snort Report works properly, but I get "NO DATA".

Can you Help me, please?

Thanks in advance!!!!!!!!!!!
