A few weeks ago, I saw that snort needs to update to 126.96.36.199 (up from 188.8.131.52-r1), but with this update, it no longer has support for snortsam. This sucks! I posted a thread about this on the Gentoo forums, but no response yet. Because of this I'm not updating my production boxes, that use snortsam as part of it's IPS. On a box that was running just snort, I had troubles getting it started. The whole thing left a unpleasant taste in my mouth.
