Posted on June 6, 2014 by robertwilkie

Why waste plastic and have one print out when you can build a pretty sturdy one out of PVC (and its cheap).  Author used 1.5 inch PVC pipe, 4 elbows, and 2 endcaps.  About $8 in parts. http://www.thingiverse.com/thing:69834

Stumbled on this while reading on some updates on SNORT.  It looks interesting, its a passive analyzer and has a good feature list.  Worth looking at in the future. http://www.darknet.org.uk/2014/05/bro-passive-open-source-network-traffic-analyzer/ https://www.bro.org/
