AFP Out Of Date In OS X Lion

thanks mgdm - makes sense, as my AFP shares do work. so i should wait it out until they release a new update that supports time machine? too late to go back to snow leopard :-)

Yes, I'd wait for the update.

Looking forward to an update for both x86 and SPARC!

Has been confirmed that an update is in the works for both x86 and Sparc?

NetGear has neither confirmed nor denied an update happening. However as they are a customer of NetAFP, I believe it is reasonable to assume that NetGear would want to update the AFP support on both Sparc and x86 ReadyNAS. One would expect that they would be able to get some assistance (even if just answering of questions regarding how Netatalk is written to help NetGear know what it needs to backport) from NetAFP if necessary to make this possible.

Agreed. Certainly NETGEAR would want to have support for Time Machine under Lion, which should be shipping relatively soon. Time Machine has been an advertising angle for the ReadyNAS and I'm sure there's a desire to keep it intact (and ideally at launch). How important this is to the company or how long customers would find it reasonable not to have support is TBD.

Found a workaround to enable (and disable) DHCAST128 in Lion, by default Apple disables support for the “DHCAST128″, which is commonly used by NAS boxes. This is because it is thought is it insufficiently secure. So all the Vendors must work with Apple for Lion compatibility.

To turn on “DHCAST128″ support please do the following on your Mac running Mac OS X 10.7 Lion:

1)  Launch /Applications/Utilities/Terminal and do:
sudo chmod o+w /Library/Preferences
Then:
defaults write /Library/Preferences/com.apple.AppleShareClient afp_host_prefs_version -int 1
Now Quit from Terminal and restart your computer.

From Finder, select an AFP server, or use “Connect To…”.  This will cause the AFP Client to create the full preferences file

3)  Launch Terminal again and do:
sudo defaults write /Library/Preferences/com.apple.AppleShareClient afp_disabled_uams -array “Cleartxt Passwrd” “MS2.0″ “2-Way Randnum exchange”
Then:
sudo chmod o-w /Library/Preferences
Now Quit from Terminal and restart your computer.

Note:  To add a “DHCAST128″ to the disable list, use
sudo defaults write /Library/Preferences/com.apple.AppleShareClient afp_disabled_uams -array-add “DHCAST128″

This has been tested on my OS X Lion 10.7 GM Installation and works like a dream.

Does this make Time Machine work again or is this just for authenticated AFP access?

Time Machine on Lion has additional requirements which are addressed by Netatalk 2.2

And we have no idea whether Netgear will support this on the Sparc ReadyNAS or not?
