agreed! glad you appreciate the feedback... it helps to keep "us" from drinking
too much during "game time" ;) ;) O:)

the main problem, as noted above, is that it is not easy to tell which OS
version compilation will work in our environment... at one time we were able to
use Centos-4.6 but that changed in later releases... then the Centos stuff
didn't work at all for a bit and folks were forced to disable the SO rules
because of snort crashing... i'm not sure which compilation might work these
days so it is not something supported out of our box... that's why i stated
"specific and manual intervention" ;)
when the drummer's drumbeat keeps changing beat count randomly and at random
points in time, it is best to find a sane and consistent drummer to march to
instead of keeping on stumbling and fumbling around... we've done that by
avoiding the SO rules in our official packages and support O:)
