Deployment Server Questions: Host matching

Communicator

Hi,

I am trying to start using the Deployment Server in Splunk to manage my enterprise of a single indexer & about 100 forwarders.

1.) I am trying to understand the whitelist/blacklist host matching. I have a series of classes & what I want to say is:
"Don't accept anything unless it matches these patterns."

To do that I have the following:
[serverClass:Intercard-Teller-POS]
blacklist.0=*
whitelist.0=.(P|p)(os|OS)
whitelist.1=.(T|t)(eller|ELLER)

The way I understood it was "blacklist everything unless it matches whitelist 1 or 2." I have a series of classes like this, then I have a "catch-all" at the end like this:
[serverClass:therest]
whitelist.0=*
blacklist.0=.(P|p)(os|OS)

where I am trying to say "match everything EXCEPT these patterns (with a list of all the whitelisted patterns used above."

Now my problem is I have a machine called BB377DTELLER2 that I am testing the configuration on & it is showing up in the "therest" class. Am I misunderstanding how the whitelist/blacklists work? I do not have anything in the top level global stanza.

Thanks!

Kevin

Your style of starting with blacklist.0=* assumes you have set filterType = blacklist above. It's probably just as easy to leave that out and use the default filtertype of whitelist.

The other issue is that the matches must be complete, so to match those patterns within the hostname, surround them with *

Try

[serverClass:Intercard-Teller-POS]
whitelist.0=*(P|p)(os|OS)*
whitelist.1=*(T|t)(eller|ELLER)*

[serverClass:therest]
whitelist.0=*
blacklist.0=*(P|p)(os|OS)*
blacklist.1=*(T|t)(eller|ELLER)*

Though filterType=whitelist is supposed to be the default, I put that in and everything is working as expected now...
