Yes, it's normal behavior for mv to overwrite without warning in this case. Use "mv -i" to prompt on overwrite.
I'd say it's a bug in Nautilus, if any. Probably linked to bug 316653.

Marking Samba as invalid as smbclient delivers expected behavior, please reopen if you can point to a specific bug/missingfeature in Samba.

Thank you for taking the time to report this bug and helping to make Ubuntu better. Please answer these questions:

* Is this reproducible?
* If so, what specific steps should we take to recreate this bug?
* How do you mount the share? is that specific to nautilus?

This will help us to find and resolve the problem.

It is fully reproductible with the steps I've descriped above.

I mount the share from the "Shortcuts" menu (not sure of the english name : it's the GNOME menu with shortcuts to usual places, recent documents, etc. between "Applications" and "System" ; it's called "Raccourcis" in french, maybe it's called "Places" in english). I use "connect to server" then choose "Windows share", set the host name, user name and the Samba share appears on the desktop. I then browse through it with Nautilus.

The server runs Ubuntu too, Samba shares have been set on it remotely via Webmin (I'm not connecting to a Windows system).

How can I check if the problem exists without Nautilus ? Are there commands I can type in a terminal to connect to a Samba share and manage files on it ?

Could you post the remove server configuration (/etc/samba/smb.conf)?

You can run the following commands from a terminal:

To test:

1. install the samba-client package
2. try to connect to the remote system from the command line:

smbclient //remote_system/share_name

If the share requires a specific username/password, try using the "-U"
parameter (for example, use "-U ntdomain\\user").

Using smbclient, I tried to rename a dummy file to an existing name using the "rename" command. Got an error message saying the file already existed.
So I guess the problem comes from Nautilus not using the smbclient commands ?

Sebastien,

The bug still exists in Lucid (fully up to date).
I hit it by mistake, renaming some TV episodes on a NAS connected through Nautilus Samba (smb://server/share).
But, as you correctly pointed out, it is not related to samba, but to gvfs.

Allow me to be brief:
D1. create two files on desktop, one first.txt, second second.txt and write "first" in the first one and "second" in the second one
D2. try to rename first.txt to second.txt. Nautilus complains: 'The item could not be renamed. The name "second.txt" is already used in this folder. Please use a different name'. GOOD!

F1. copy first.txt and second.txt to a ftp server via Nautilus FTP connection.
F2. try to rename first.txt to second.txt. BAM! You've just lost the original second.txt

S1. copy first.txt and second.txt to a samba server via Nautilus SMB connection.
S2. try to rename first.txt to second.txt. BAM! You've just lost the original second.txt

This should not happen. Of course, Thierry is right, mv does not prompt. In this case, please remove the prompt from Nautilus in D2 case (on the desktop). Oh, the developer intent was to protect the user. In this case, protect the user also when he/she is using smb or ftp in Nautilus through gvfs.

Thanks,
Dan.
