[Snort-users] Barnyard2 Failing on Write to SQL Database

Thank you, Marcin, I appreciate your prompt reply. I will check into the
questions you asked. Some of the terms are new to me, such as json.
This problem cropped up a couple of weeks ago and I suspected that there
was a change in the rules file that I didn't notice.
I had both Snort 126.96.36.199 and Snort+ installed perhaps six months ago.
Snort+ was giving me problems and 188.8.131.52 was working so I quit playing
I suspect that the most expedient thing for me to do is to bring Snort
+/3 up to date and try Evebox.
