The recent release of OS X version 10.6 (Snow Leopard) for the Mac has introduced a permission problem when copying certain files that e.g. have been downloaded from the Internet.

If you’re using a Netatalk version >= 2.0.4 you can use the following workaround of adding fperm=0600 to the volume configuration file for every volume or by adding it to the DEFAULT config line, e.g.:

:DEFAULT: fperm:0600
