Hey guys, my xbmc install refuses to play certain files from my smb server. It seems to be a permissions issue, but no other computer or device has the same problem. It seems that files owned by the user monsoon are unplayable, but files owned by the user joshua are fine.

The xbox is logged in as the smb guest account, like any other device.

The server is OpenSolaris snv_134, the files that wont play are owned by monsoon, with 775 equivalent permissions:

Code:
joshua@Proto:/storage/media/_New/torrents/complete/public tv$ /usr/bin/ls -V \[DB\]_Bleach_271_\[5FF99426\].avi 

-rwxr-xr-x+  1 monsoon  other    178387768 May 19 23:28 [DB]_Bleach_271_[5FF99426].avi

                 owner@:rwxpdDaARWcCos:------I:allow

                 group@:r-x---a-R-c---:------I:allow

              everyone@:r-x---a-R-c---:------I:allow

           user:monsoon:rwxpdDaARWc--s:------I:allow

joshua@Proto:/storage/media/_New/torrents/complete/public tv$ ls -la \[DB\]_Bleach_271_\[5FF99426\].avi 

-rwxr-xr-x+ 1 monsoon other 178387768 2010-05-19 23:28 [DB]_Bleach_271_[5FF99426].avi

Here is the debug log from xbmc showing a file owned by monsoon that is unable to be played:

Does anyone have any idea what could be the issue here? im pretty stumped.

While I'm no Linux guru, perhaps a quick primer on how SMB permissions work under Windows will shed some light on the matter?

The file system is typically NTFS, under which files have an owner, and a list of users/groups who have read/write/execution rights (one of these groups can be "Everyone"). Administrators may "take" ownership of any file they wish, then change the permissions as they see fit (but they can't "give" ownership back, so if such tampering is performed, it's pretty obvious).

On top of the filesystem permission scheme, you've got SMB permissions, which are assigned in much the same way as NTFS permissions but are treated separately. To access files via the Guest account, the Everyone group must have access to the files in concern.

Usually, receiving an outright "access denied" error (instead of a "please try to login again"-type message) would indicate that the SMB permissions are ok, but the file system permissions are out of whack.

Given that your other systems are accessing all files with no problem, it might be worth checking what username and password they're using to login with.

I run a linux based QNAP file server. I've noticed that when some files are modified or transferred by/from a windows based machine permissions can get messed up. And the xbox seems most susceptible to this.

I periodically run a script to reset permissions on the server.

Can you go to a directory and run [b]ls -l[/] to show file permissions and post the output?
