You do not need to reinstall snort. You need to enable the unified log
output plugin though. Sguild runs on it's own DB schema which will be
created the first time you run sguild. That DB can coexist with others (like
the one for BASE).

Paul,
Thanks for the reply. I have looked at sguil (following your post) and I
think it may cover what I am looking for, but the install documentation
indicates relations to lots of other packages such as NSM and p0f and
includes a lot of detail on setting up the snort install, logging to what
looks like another database (i.e. a sguil database rather than the initial
snort one which is included in the snort documentation).
I don't mind re-installing snort from scratch if necessary, but I'm trying
towork forward from an existing snort install and add this alerting
function. Do you know of any documentation covering adding sguil to an
existing install, or whether I just need the exisiting database ?
Thanks,
David
