Re: Snort + Barnyard2 + Base Issue

Hi Guys, Sorry for the late update but I found out the issue was due to me not configuring and installing all of the packages as root. I went back to a clean install of Fedora 14 and followed the instructions again all as root and now the waldo file seems to be working fine with alerts being pushed to BASE. Thanks again for the help! On Thu, May 19, 2011 at 3:19 PM, Nick Moore <nmoore () sourcefire com> wrote:
Ryan, Are you sure you are getting traffic that would generate an alert? The easiest way to confirm this is to create simple rule that alerts on web traffic, then surf the net and see if you are getting alerts. If you do this with your console open, you should see alerts scrolling, as you still stdout turned on in barnyard2.conf.
