I would like to reiterate that mount.cifs does not transmitted password in
plain text over the network. Unless you use ancient version, which I do not
think is possible without extra effort on your side.

[PLUG] winscp

2017-12-05 Thread michael
I'm thinking about how to address security concerns with mount.cifs from 
a Pi 3 running Raspbian Stretch.


An option is to have the customer run winscp server on their Windows 
server and give me a login/password to a limited account that can see 
the relevant shared files on the windows network.


Granted, once I'm connecting via a limited account, the security 
concerns are less for mount.cifs.  OpenSSH is the code behind winscp, 
but from what I can see, the administrator has to install winscp.


If I ignore the security concern that the password transmits in the 
clear with mount.cifs, it is simple for the Windows administrator to set 
up a share and a limited login that can access that share.


As far as active directory, etcetera, I don't understand how that works 
where I lack the necessary time to learn how that works.  PC-NFS has 
problems similar to  mount.cifs, unless of course Kerberos is used for 
authentication.  Again, I don't have time to learn how to setup Kerberos 
and it would be a lot of work on the windows side.


The Raspberry Pi 3 model B is limited on processing power and memory.  
Push it hard enough and it will overheat.  Keep in mind, the only time 
truss files need to transfer from Windows to the Pi is when there is a 
request for a new one that isn't already locally available.  If scp is 
used, that should be lighter than keeping a CIFS share or an NFS share 
mounted between Linux and Windows.
