Accessing SMB shares without explicit mounting

Accessing SMB shares without explicit mounting

[Phil Reynolds]

In order to cut down on the overall time my backups are taking, I am  
thinking of running flexbackup under cygwin. However, I will want it  
to write to a directory I have shared from my Linux box using samba,  
without mounting it explicitly.

I understand that this at least ought to be possible using a UNC path  
(//server/share) but all attempts to list the current content are  
showing it to be empty. If I try to access a file I know to be there,  
or to create a new one, I get "Permission denied". I can clearly see  
that the shares are there, but cannot make any practical use of them.

I am therefore left in the position of having to seek advice on this.  
The permissions do allow the shares to be mounted in Windows, but in  
the case of this particular one, I am looking for it not to be mounted.

I am quite happy to post further details if needed.

Thanks,

Phil Reynolds.

It sounds like your Samba configuration requires authentication in order
to access this share.  Are you able to access the share as
\\server\share using the Windows file explorer without first mapping the
share to a drive or authenticating in some other way?  Cygwin uses
Windows to handle this sort of operation, so if Windows can't access the
share without authentication, neither can Cygwin.

If authentication is required, you'll either need to map the share to a
drive letter or reconfigure your Samba share to allow guests to have
read and possibly write access depending on your needs.

Thank you - this has pointed me in the right direction...

The main problem I've got now is how to allow write access to the  
share from this scenario without allowing it from outside... but I am  
working on that.

Might you be able to do something like:

net use \\server\share /user:[<domain>\]<username> <password>

To access the share supplying the username and password so that you can 
then use the UNC path proper? For example:

Pluto:net use \\\\jupiter\\Video /user:<username> <password>
The command completed successfully.

Pluto:net use
New connections will not be remembered.


Status       Local     Remote                    Network

-------------------------------------------------------------------------------
OK                     \\jupiter\Video           Microsoft Windows Network
The command completed successfully.
