NAS Access / Permissions.....???
 

I have a USB 3TB drive sitting on a Netgear R3600 router on my network, everything related to routing/switching/DHCP etc, is turned off. I only want it there to "host" the external drive as a NAS.

The router has a static IP address on the network, my problem is that I want it to mount automatically on startup for (basically) any computer on the network that connects and have read/write ability to it.

I can "see" it but cannot "get" to it. When I try what (to me) is logical, (double click the share) in the left pane of the filemanager window it returns this:

An error occurred while accessing 'Home', the system responded: mount: only root can mount //192.168.0.200/USB_Storage on /home/time/readyShare/

See Attached image.

Please advise on how to complete this task.

Thank you

IF the usb drive keeps 192.168.0.200, you will probably have to add a line in fstab. I believe its in /etc. Man fstab should help with the syntax. There are umask and user options. I screw mine up regularly, so make a copy before mucking with it. To edit this will require sudo or root.

I'm gonna go look for an example.........

Does the drive use GPT?

Is the router capable of using > 2 TB drives

How is the drive formatted?

Have you configured shares and login accounts etc on the router?

Are other computers capable of accessing the shares?

The error is fairly clear: you're trying to mount a drive and your system is telling you that only root can do that. You've got some options:

• You're using Dolphin, which hints at KDE strongly. You should have a "File Manager - Super user mode" option available to you, which will prompt you for your root password. It should then let you do what you're after.
• Add your user to the "disk" group, which will allow it to mount shares as a non-root user
• According to the manual (http://www.downloads.netgear.com/fil..._20May2015.pdf), you can either use FTP or HTTP to share a USB drive on that router. That being the case, either mount it via http (using davfs) or with FTP (using curlftpfs).

You don't say what version/distro of Linux, but you can easily put something on your system to auto-mount this share when booting, either via fstab or the dispatcher (I'm on Tumblweed, and that works for me).

The router is also capable of sharing files using CIFS. The manual shows it as network neighborhood on page 33.

I have an older model Netgear router and don't have any problems but I don't have KDE runing on any of my systems.

Good catch; if it has CIFS, you can also mount it with CIFS, OP. But I think the OP's problem isn't the file system, but that they can't mount it without root/sudo rights.

Thank you to all who responded, all of your help and suggestions are greatly appreciated and taken into account.

The analysis that the primary problem seems to be the mounting/permission rights, at least that is the first issue I am facing, and I think once solved will be the last hurdle to jump, for the most part.

I am running a Plasma Desktop KDE. If that helps also see below:

Ok first attempt results:

I did a right click on the dolphin icon in the "Start" menu, selected <Edit Application> from the resulting pop-out menu in the Application tab at the bottom right of the window selected <Advanced Options> in the middle of the resulting window is a "box" labeled "User" I ticked the radio button for "Run as a different user" and in the "Username:" field I put "root" selected the <OK> button and the window dismissed.

Upon launching of Dolphin in the usual manner it now asked for my root password, which I provided and dolphin opened when I tried to access the NAS I received the following error message:

=====================================================================
An error occurred while accessing 'USB_Storage on 192.168.0.200', the system responded: mount: wrong fs type, bad option, bad superblock on //192.168.0.200/USB_Storage,
missing codepage or helper program, or other error
(for several filesystems (e.g. nfs, cifs) you might
need a /sbin/mount.<type> helper program)

In some cases useful info is found in syslog - try
dmesg | tail or so.
=====================================================================

As the message is hinting at a "helper program" and I have herd cifs mentioned more than once, I will try to install a package through synaptic package manager to assist and will report back the results.

Thank you again for all the help...

I just tried to ad myself to the user group disk as suggested:

Add your user to the "disk" group, which will allow it to mount shares as a non-root user

======================================================================================
time@SATTime-2:~$ sudo su
[sudo] password for time:
root@SATTime-2:/home/time# adduser time disk
Adding user `time' to group `disk' ...
Adding user time to group disk
Done.
root@SATTime-2:/home/time#

Result:

An error occurred while accessing 'USB_Storage on 192.168.0.200', the system responded:
mount: only root can mount //192.168.0.200/USB_Storage on /home/time/readyShare/
======================================================================================

what I THINK I need is a directory somewhere (not sure where) named /readyShare that connects to the NAS, I think its kind of like mounting a standard usb thumb drive, but I forget how to do that....I will look this up and give it a try as well.....

My attempt at Creating a mount point:

Adding CIFS and rebooting (just for good measure) seems to have done the trick, I can now read-write-mod-save files.....

Thank you all once again for your help....!!!!

Your trying to mount a samba share i.e. SMB/CIFS. The basic syntax is
You must be root or have sudo privileges.

I see that you have already figured it out.

I figured it out by happenstance on my first computer, when I moved to another computer on the network it did not work the way it did on the first one....both Debian same version but the ability to mount an IP address is or was in the back of my head but I didnt think it possible like you are showing I will try that on the other machine....thanks for the tip....

I had the following in /etc/fstab on the second machine:

=====================================================
#AUTO MOUNT NAS AT STARTUP
//192.168.0.200/USB_Storage /readyShare cifs x-systemd.automount,guest,noperm,$
=====================================================

I commented it out and replaced it with:
=====================================================
mount -t cifs //192.168.0.200/usb_storage /media/nas
=====================================================

In the process I noticed USB_Storage with Capitol letters, I don't really think it should make a difference, however I am checking on the first machine that is working to see what I have there.....

The other machine reads like this: (I will copy/paste into the other and see what happens)

=====================================================
#Test to see if NAS will mount
//192.168.0.200/USB_Storage /home/time/readyShare/ cifs x-systemd.automount,guest,noperm,sec=ntlm 0 0
=====================================================
