    Hi,

    I have Little Snitch running on my Mac, and I notice most of the programs that are soliciting connections are those I have seen before, but some I'm still wondering what they're exactly doing.

    "DirectoryService" connects to 192.168.2.1 (I'm on a wireless router, if this helps).

    "Finder via nmblookup" was connecting to : 192.168.2.255.

    Can anyone tell me what these processes are, and what they're doing?

    Learn to use the man command line tool :p

    man DirectoryService tells us :

    DirectoryService -- DirectoryService daemon (a part of Mac OS X's Open Directory architecture)

    then a lot of descriptive text

    man nmblookup tells us :

    nmblookup - NetBIOS over TCP/IP client used to lookup NetBIOS names

    So this would be looking up the names of shared Windows computers/Macs with Windows sharing on.

    Oh, I've done a ton of research on both... but all in this network jargon I can't understand. why would Finder be doing this? i don't have anything else on my WiFi besides myself and my xbox... the finder is also doing this randomly. I only have safari/ichat running. Does your nmblookup connect randomly?

    I tried disabling it in the Little Snitch Config app, and I was warned not to disable a protected rule, necessary for smooth system operation. Still don't know where it came from.
