Ubuntu – Make Nautilus mount SMB share with Protocol 2.0

nautilussamba

When I mount my SMB share via Nautilus, transfer speeds are slow. So I did some digging and found that when I mount the share via CLI and specifically set the protocol-version to 2.0, it's much faster.

Here is the command I use on the CLI:

sudo mount -t cifs -o vers=2.0,username=Lukas,password=xxxx,uid=1000,gid=1000 //nas/video /media/lukas/nas

How can I make Nautilus use Version 2.0 when mounting my share?

The Nautilus Version is "GNOME nautilus 3.26.3"
The Gnome Shell Version is "GNOME Shell 3.28.3"
Ubuntu Version is "18.04.1 LTS"

I have a alternate suggestion if you are interested. Instead of messing about with how the samba client accesses the NAS - which as I said should be unnecessary since it will use SMB2/3 by itself if required - why not just use CIFS automatically?

Add the following line to the end of /etc/fstab:

//nas/video /media/lukas/nas cifs vers=2.0,username=Lukas,password=xxxx,uid=1000,gid=1000,noauto,user 0 0

Note: The server can also be expressed as an mDNS qualified hostname if the server supports it: //nas.local/video Or an ip address: //192.168.0.100/video

How this will work:

noauto = will make it so that it doesn't mount at boot. We are going to set this up to use CIFS on demand when you need it - useful if you have a laptop.

user = will make it so an ordinary user ( non sudo ) can mount the share.

mount point = Since it's under /media it will induce a udisks response:

(1) An icon will appear on the side panel of Nautilus.

(2) It will be "actionable" - click on it and the system will go to fstab to find out how to mount it then mount it - click on it again to unmount the share.

There is a side benefit to this approach. The icon that it will add to Nautilus will also show up in most of your applications - like gedit > Open for example. Then you can mount the share from your application directly.

Note to anyone reading this: The mount point is important here. For the udisks magic to work the mount point has to be under /media or your home directory.

Ubuntu – How to access a password protected share from nautilus

The new nautilus in 13.04 (raring) no longer shows a place to enter connection credentials. This makes it really hard to connect if you don't know the URI syntax. You can find help for the SMB URI syntax at Wikipedia.

Basically, use one of these URIs:

smb://[<user>@]<host>[:<port>][/[<path>]][?<param1>=<value1>[;<param2>=<value2>]] or
smb://[<user>@]<workgroup>[:<port>][/] or
smb://[[<domain>;]<username>[:<password>]@]<server>[:<port>][/[<share>[/[<path>]]][?[<param>=<value>[<param2>=<value2>[...]]]]][5]

The user name can contain spaces explicitly and doesn't require encoding. Myself, I used the following:

smb://My User@WINDOWSHOST/Share

You then are prompted for the credentials. I'm not sure if the share name can have a space since my shares don't have them, so I haven't tested it.

Once you access the share, you can right-click on it in the left panel and Bookmark it. This will make it remap when you log off and back in so you don't have to keep using the Connect to Server method all the time.

Ubuntu – Specify SMB 3.0 in /etc/fstab

I had the same problem which was also due to an upgrade to one of my institute’s servers. I managed to mount the share by adding the vers=3.0 option to fstab without the -o argument.

sudo mount -t cifs //192.168.1.100/Movies /mnt/Media vers=3.0,user=plex,uid=111,gid=1000,pass=PASSWORD
