Hi, even strange it is working now. Strange! ip_queue was already loaded. Can it unload from itself??? owever, I have inside syslog: Sep 17 11:11:57 nova5 modprobe: modprobe: Can't locate module iptable_QUEUE and till now I was unable to see in real SNORT to block any traffic. Is inside rules a way to know if a rule drop or log or ........ now SNORT is running with: modprobe ip_queue iptables -A FORWARD -p tcp -m tcp --dport 80 -j QUEUE snort -c /usr/local/snort/etc/snort.conf -g snort -u snort -X -U -y -s -Q -D --disable-inline-initialization I have added --disable-inline-initialization so to be sure (becouse I'm testing on a production machine and not wanting to have strange results). Owever even if I run it without --disable-inline-initialization it seems to not block for example P2P traffic. It log it but nothing else. Is then a way to see packets and QUEUE activity?. iptables -A FORWARD -p tcp -m tcp --dport 80 -j QUEUE send only port 80 traffic to be sniffed from snort inline? and if I would like to have all traffic sniffed as when snort run in NOT INLINE?. * I'm really new to snort :D ------------------------------- Alberto Colosi IBM Global Business Services Sistemi Informativi S.P.A.

You must run as root to interact with ipqueue Regards, Will On Tue, Sep 16, 2008 at 9:32 AM, Alberto Colosi/SI/RM/GSI/it <alberto.colosi () sistinf it> wrote:
hi, an information. while working snort 2.8.3 have stopped to log inside syslog. I have restarted my machine and I have restarted snort many times. It is inline compiled but not working in inline. After different tests I have runned it not in DAEMON mode and I got a "sending netlink message: Connection Refused" why it happened? I have changed nothing ....... or at least I think so.
No
other users could have changed anything becouse noone compile or
configure
anything there. Running snort without -Q, not reading from IPTABLES, it has started to
work
again. What's on??. ------------------------------- Alberto Colosi IBM Global Business Services Sistemi Informativi S.P.A. IT NetWork & Security Department *-* *-* *-* SECURITY IS EVERYONE'S BUSINESS Member of IBM Information Security WW CoP
