Interesting permissions problem

Ive been using various linux/BSD distros for several years and recently switched from Gentoo to Arch.  So far, I'm loving it.  I've just run into an interesting problem that I have never seen before.  I have an XFS partition mounted on /mnt/media that I use to store all my music, videos, etc.  After the new installation, everything in that partition was owned by root:root with 755 permissions.  Normal so far...  I wanted to have everything in that folder owned by my user acct so i could write to it so i issued a `chown -R daemontux:users /mnt/media` and then set new permissions on everything with `chmod -R 644 /mnt/media`  Here's where the weirdness begins - when i `ls -l /mnt' everything looks good permissions show

drw-r--r-- 21 daemontux users 4096 2007-07-06 05:39 media

but if i do `ls -l /mnt/media` every file shows up as

?????????? ? ? ? ?                ? videos

I have tried reseting all permissions to root:root 755 but am getting the same problem.  The weirdest thing is that when i `sudo ls -l /mnt/media' everything looks right -

drw-r--r--  4 daemontux users       137 2007-07-06 05:40 videos

I now can't access this folder at all as my user and I really dont want to run amarok and mplayer as root   Any ideas as to what may have happened or where to go from here would be greatly appreciated.

Re: Interesting permissions problem

Don't chmod the directory to 644.  This removes the executable permission from the folder.  Executable on a folder means the ability to browse it, so you are removing your ability to browse the directory.  I think leaving it as 755 should work fine.  If you want to change all the files to be not executable you probably need  a quick script to test each file to see if its a directory before changing the permissions on it.

Re: Interesting permissions problem

Thanks for the help.  That seemed to do it...  i think ill just set the noexec option in fstab rather than do the script tho.:)
