Binary package hint: samba
I'm trying to use a samba share via CIFS and am encountering problems
when trying to copy or move files onto the share. If I create a file
directly on the share it works as expected (using my umask for
permissions) but copying or moving result in errors. To reproduce:
root@boris:/mnt# mount -t cifs //arctic/holding /mnt/testo -o
credentials=/root/arctic.cifs.key,domain=Island,iocharset=utf8
root@boris:/mnt# mkdir ~/z
root@boris:/mnt# mv ~/z testo/
mv: failed to preserve ownership for `testo/z': Permission denied
mv: preserving permissions for `testo/z': Permission denied
root@boris:/mnt# ls -ld testo/z
drwx--S--- 2 clouserw root 0 2009-12-14 21:38 testo/z
root@boris:/mnt# umask
0022
This looks _a lot_ like (and might be a duplicate/dependent on) debian
bug 532153 ("cifs reports EACCES instead of EOPNOTSUPP for acls"
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=532153). It looks like
that bug is still open though and I'm not sure what the progress is or
if there is a workaround in the mean time.
Neither my server or client have ACLs on their filesystem. One maybe
relevent note is that mounting the same share from OS X and moving files
onto it works as expected with permissions being preserved. OS X has a
concept of ACLs on by default.
I'm attaching an strace.
