Hello,
AFP is convenient, the shares simply show up in the Gui.
SMB corrupts longer Mac file names, so I can't use it.
After searching the web, other Linux based NAS solutions have the same problems (i.e. QNap). Apple dropped "DHCAST128" and uses a newer version.
There is a trick with works by enabling the old version in OS X 10.7, but it has to be done in the terminal on every Mac running 10.7. Not user friendly enough for us.
Maybe open-e will use the newer AFP protocol in the next version.
thx
