Thread: [Samba] Samba not seeing any interfaces

  1. [Samba] Samba not seeing any interfaces

    I've built samba for an embedded mips platform. Since this is an
    embedded platform, it's possible that some critical file that samba
    needs is missing but stracing the daemons doesn't reveal anything strange.

    It's running 2.4.34 kernel.

    Samba is failing to find any interfaces.

    I added some debug lines to the interface.c routines.

    It turns out that get_interfaces returns -1 - eventhough there is an
    interfaces = line in smb.conf. From looking at the code, this is not
    handled at all in interface.c.

    WARNING: no network interfaces found
    found -1 interfaces


    Any idea why the kernel wouldn't return any interfaces?
