Ah.  I actually had that originally, but since it wasn't working, I
wasn't sure if it used "real" regexes, or "DOS command-line" regexes.

Ah ha!  That explains it.  I removed the second ignore, and it's
working perfectly now.

Ah, that's simple.  Note to self: if there's something you want to do
with Hobbit, it's probably done fairly simply ;-)


Just ONE remaining issue now.  There are still additional log files I
want to check for that aren't showing up.  I have this specific
hosts's client-local.cfg entry defined as:

[master.homeoffice.none]
log:/var/log/samba/client.nmbd.log
log:/var/log/messages:10240
log:/var/log/maillog:10240
ignore relay=localhost\.localdomain
trigger denied

The "messages" and "maillog" entries are showing up just fine, but the
"client.nmbd.log" file is not showing up; not even with an empty "full
log" section.  Any ideas?

Also, do I need the escape character "\" to ignore the line that says
"relay=localhost.localdomain"?  I guess since "." means "any
character", it will work anyway without the "\"...
