A comment on the problem "Hanging Filesystem integration (Linux)" in Wuala:

Sorry, that should be "Retrying to copy the files into Wuala" not "Trying to copy the files there again". I'm not manually putting stuff into the /tmp/ directory... – DataWraith, on November 05, 2008 19:46

I'm not sure whether I'm having exactly the same problem, but the filesystem integration does hang an awful lot, and this is probably related, so...

When copying many small files, or one larger file (above ~100MB), to Wuala, it hangs after a while. You can literally see the progress bar stopping in the "Copying files" dialog. Often I'm lucky and it resumes after ~10-30 seconds, but other times the operation is aborted with a complaint about "lstat" failing.

After that, the filesystem integration is broken. I can unmount and remount it, which helps a little, but invariably Wuala will hang again after a short while and has to be restarted.

When shutting down, Wuala then outputs the following messages:

Had to kill thread Thread[Mnt_Mountd,4,main]

(Repeated about 10 times)

This sometimes leads to dead files that were'nt uploaded properly. On restart Wuala emits

Problem: Could not upload file xyz.                                                                            

Reason: /tmp/WualaTemp/deadbeef-xyz (No such file or directory)

(deadbeef = random hex string)

Trying to copy the files there again leads to an error (though not always, I haven't fully figured this out yet).

I'm running Intrepid Ibex, 64bit.

A comment on the question "When you share a file with a friend or private group, how is the key transferred?" in Wuala:

Hm. True.

I think I remember something about a friend-key being generated when you add a friend, for encrypting communication with that friend, but I can't find the source of that right now. Maybe I mixed things up. But even so, to keep communication with friends private you'd either use public key cryptography or generate such a friend-key using Diffie-Hellmann or something similar.

The speculation is moot though, until we get confirmation from an employee. – DataWraith, on September 20, 2008 17:07

There's a paper that describes Wuala's access control system:

http://wua.la/Luzius/Documents/Papers...

Basically you have a tree of keys that corresponds to your folders. The encryption keys of files/folders can be derived from the encryption key of the parent folder. To share a folder, as far as I understand, you give the key of that folder to a friend, who can then derive the keys of all files and subfolders from that, without being able to encrypt files above the folder you shared, because derivation only works "downwards".
