Hi,

I have some difficulties..
As user internet...in console..
command...
su -c "rsync -auvr /home/internet/tstrsync1/ /mnt/win_d/tstmdk1/ 1> 
auvr-su.txt 2> auvr-su.err"
results.....
auvr-su.txt...
building file list ... done
<<snip>>
use-update
wrote 1179 bytes  read 132 bytes  2622.00 bytes/sec
total size is 672  speedup is 0.51
**
auvr-su.err...
chown . : Operation not permitted
<<snip>>
chown use-update : Operation not permitted
chown . : Operation not permitted
rsync error: some files could not be transferred (code 23) at 
main.c(620)
**
 In destination dir..files is there but now owner & group = root.
The output says chown is not permitted but is done

Please...I am at a loss here..Kindly some pointers.
