Path Finder connects to an external IP 5.7.146.160 on port 139

Path Finder is regularly attempting to connect to an IP address not on my local network -- 5.7.146.160 -- what's the purpose of this? I wouldn't expect to see port 139 being used outside my local network.

    Hi bulbous,

    I'm terribly sorry for such a delayed response, only now I see your question (and I'm constantly busy, so forgive me for that :-))

    There's nothing really fishy going on there. As you may know, finding SMB shares can be a bit problematic in Lion (and later versions of the OS X) since Apple has removed all SMB tools from the system and started using its own SMBX, which is not available to 3rd party applications developers. Therefore we bundle SMB tools with Path Finder starting from version 6, but we tried to do some more "tricks" to streamline the process of connecting to SMB shares

    One of those tricks is that once Path Finder finds a particular SMB share, it remembers its IP address in the preferences file. Next time you launch Path Finder, before trying to find the same server it first tries to connect to it using the remembered IP address. So what probably happened here is that you've been connected to some network (perhaps wirelessly) and Path Finder has found some Window machines and their shared folders (as SMB shares) with the addresses Little Snitch reports. Upon finding and connecting to them, Path Finder remembered them in the preferences file. You couldn't see any activity reported by Little Snitch at that time, because everything happened within the local network.

    Once you removed your system from that network, Path Finder still tries to connect to those IP addresses on launch, but since they're not local, it tries to establish them outside your local network so you see Little Snitch reporting them. If Little Snitch isn't installed, everything is hidden from the user, the connection won't be established (because the same shares wouldn't be find). But the things can get annoying with Little Snitch (or an app with similar functionality installed).

    You've got two options here:

    1. Just allow Path Finder (actually the bundled smbclient tool) to connect to those addresses for good, nothing bad will happen.

    2. Open Terminal.app and type this:

    defaults delete com.cocoatech.PathFinder NTSMBMasterBrowsersPrefKey

    and press ENTER

    Let me know whether this solved your problem.
