various access right issues with cifs

[Gilles]

Binary package hint: smbfs

I have been testing cifs due to current smb issues with large files (see bug #38886) and I have stumbled across a number strange behaviors. Most of them are related to access right issues.

I am using Ubuntu 6.10 (edgy), kernel 2.6.17-10-generic, and samba 3.0.22.

I mounted a Western Digital Netcenter NAS drive (which for testing purpose has been set to allow anyone to do anything) using the following command:
sudo mount -t cifs "//wd-netcenter/Shared Files" nas -o guest,file_mode=0777,dir_mode=0777

I used this command for the mount as there are problems with uid/gid (see for example #48418).

Now if it try to copy small files it works fine but as soon as I try bigger files (anything that takes more than 5 seconds to copy) I get:
Error "Access denied" while copying XYZ

Also if I try to touch a file (on the mounted drive) I get the following error:
touch: setting times of `toto': Permission denied

But still the funny thing is that the file still gets created!!

Now, if I do the same command with sudo then the 'touch' works fine and with no errors.

Lastly, when I do a 'ls -l' all the files on the NAS shows with uid=35000 and gid=42000 so I suspect it is probably related but that's why I used 'file_mode=0777,dir_mode=0777' in the mount command (I would have prefered to force the uid/gid to be set but as indicated ealier this does not seem to work very well either).

uid/gid thing is fixed in feisty and i can't reproduce your problem in gutsy and feisty..

Did you maybe upgrade Edgy to Feisty and did the status of the problem changed?

This should be closed now.

Yes, I now moved to 7.10 and I can't reproduce the problem either. So I am going to close it...

[Gilles (ubuntugc1)]

Ok, that's going to seem silly but I apparently I don't seem to have the rights to close it (at least I can't find the command anywhere) so it seems some admin will have to close it for me.

Thanks.

Gilles.
