Hi Erdem,
Maybe it would better to install snort and dependencies from source. But no matter. Run snort with this command:
snort -v -c /etc/snort/snort.conf -Q --daq nfq --daq-var device=eth0
I put my snort config file in /etc/snort. So if you put it in another location, change it in the above command. Also 
note to enable nfq daq in snort config file.

Hi Meysam,
I installed these libs  and  libdnet-1.12. 





And I run --daq-list command 
Available DAQ modules:


pcap(v3): readback live multi unprivnfq(v7): live inline multiipfw(v3): live inline multi unprivdump(v2): readback live 
inline multi unpriv


afpacket(v5): live inline multi unpriv
Snort gives this response.

Hi Erdem,
Did you installed nfq library from netfilter.org?

Hi, 
I am new on Snort
I installed with guide and run IDS mode.
I have two problems. 
Firstly, Snort handle only host machine packets. I write some rules example:




alert tcp any any -> any any (content:"www.facebook.com";msg:"Facebook Accessing";sid:1000001;)
This rule works only machine which installed Snort. Other machines accesses are not handled.





Other problem is Inline Mode.
I run with this command 
snort --daq nfq -Q -c /etc/snort/snort.conf  --daq-dir /usr/local/lib/daq --daq-var device=eth0 -i eth0






Snort gives this error
ERROR: Can't initialize DAQ nfq (-7) - The nfq DAQ module does not support interface or readback mode!
If I remove "-i eth0", Snort works but do not handle any packets





Thanks for replies
Good Works
