If it gets to "Found music server", then it's probably mounted the NFS mount. There's either something wrong in the mount permissions, or there's something wrong in the mounted image.

I don't know how you configure NFS on OS X, but my page explains how to configure the Linux NFS server. Note that you need to have (no_root_squash) on the mount point, otherwise the /dev files don't work. The (insecure) allows for connections from port numbers > 1024, and the (ro) is obvious.
