could connect to NAS, now can't

mogmog · 06-27-2015, 04:02 PM

Hi,
I did something (unknown) a few days ago & lost network connectivity. I somehow got it back but have found that my NAS, which showed up before, is unreachable.
It was

Code:

file:///run/user/1000/gvfs/smb-share:server=dlink-8ce047,share=volume_1

I've looked at pages and pages of stuff about SAMBA, you start following it then part of the thread/tutorial etc doesn't work, leaving you stuck.

Would be most helpful to be able to reset my network settings to install default (only a few days ago)

Any advice welcomed.

So typically the above is created when your file browser connects to a windows network share. Most file browsers have a built in samba client and use gvfs to connect to the share. Yes, you can access it from the command line but most on line tutorials etc will have you mount the share via the old fashioned way i.e.

mount -t cifs /server/share_name /mnt/point -o mount_options. (must be root or use sudo)

Michael thanks for that insight.
I've run the above, but not really sure what it is telling me:

Code:

"The command is `mount [-t fstype] something somewhere'"

Trying to relate that to server/share_name and what I know (limited), I end up with this:

Code:

sudo mount -t fstype dlink-8ce047,share=volume_1

but that just runs the usage instructions again.

Not only does the NAS not show, it is unable to mount the Windows network.

The posted command was an example and not something you could copy and paste. I also forgot to include the mount point.

However, what do you mean by it is unable to mount the windows network, your file browser? I assume you are using nautilus. What happens when you try to browse the network? Can you access the NAS from other computers on your network?

mogmog · 06-28-2015, 10:36 AM

I didn't copy & paste as is, I tried to interpret your example & showed what I ended up with.

The file browser is Caja 1.8.2.

If I go Computer > Browse Network I get a Windows Network folder, Prior to this, it contained two workgroups, through one of which I accessed my NAS (DNS 323).

Now, after a long pause, I get the message "Unable to mount location"

Re other PCs on Network. Yes. And no - on W7 PC nearby it seems to be flaky, with Windows reporting unable to connect but sometimes connecting & I accessed the admin pages through the IP address but can't even do that from my LM PC.

I've just connected it directly to my PC. I can ping it OK but can't access the admin pages through IP address on Firefox.
Now connected direct to W7 PC - can access for a short while then becomes unavailable.
Looks like it may be an issue with the NAS rather than my Linux.

michaelk · 06-28-2015, 10:45 AM

Looks like the NAS has a problem. I assume you have tried cycling power etc?

mogmog · 06-28-2015, 11:10 AM

Yes. Powered down & up. Might try letting it cool right down to see if I get more uptime. Just coincidental timing of my self-inflicted network problem & NAS getting stroppy!
I'm hoping that as it uses either ext2/ext3 FS I can mount disk in PC to get at data.
Time to move to a different forum I think...
Thanks for your help anyway. I've learnt a bit more.

michaelk · 06-28-2015, 11:16 AM

I believe D-link does use an ext filesystem and you should be able to access your data from the linux PC. If the NAS is using RAID then it is a bit more complicated but still doable.

mogmog · 06-28-2015, 11:36 AM

Thanks for the encouraging comment. Not RAID, just standard disks.

mogmog · 06-29-2015, 01:36 AM

NAS dead, disks good: in my PC now & both accessible.
Unlike my Windows Network. Just been through a load of SAMBA steps/entries/add lines, change this etc but still nothing.
Can I reinstall SAMBA or anything else to start afresh?
Thanks in advance.

Try adding the below share to your smb.conf file and restart samba. You might need to post your configuration file so we can see the global section. You also should add a samba password for your users via the smbpasswd command. Make sure the workgroup name is the same for all computers.

Code:

[myshare]
    path=/mount/point
    printable = no
    browseable = yes
    guest ok = yes

The following command will show a list of shares.
smbclient -L localhost (just press enter when prompted for a password)

The output should display information for myshare. testparm is a utility to check the smb.conf file for syntax errors.

mogmog · 06-29-2015, 01:01 PM

I've done that, seemed to accept it.
Wasn't sure if the entry path=mount/point is the entry or I should put my path in there .../Desktop: I tried both but not sure what is supposed to happen. Nothing appeared on desktop.

Samba config file has workgroup=DAVITS but has DAVITS as domain. Probably right but I'm puzzled: it woolly on Domains (inter alia).
I appreciate your time & help on this as I'm completely in the dark.

michaelk · 06-29-2015, 02:23 PM

The path is mount point i.e. directory where the drive is mounted. If it is automatically mounted then typically /media/username/label. I assume not since you mentioned nothing was on the desktop.

mogmog · 07-02-2015, 05:50 AM

The only thing in /media is the Linux partition of the main SSD.
NAS is dead & I'm looking for a replacement, so have nothing urgent to network to (other than the Windows PC should show up so I could connect if necessary)

I'm losing the will to live over this: it all just worked when I installed LM17 Qiana some while ago yet this install (LM17 Rebecca) has given me no end of niggles, both major & minor (eg the desktop suddenly reverting to a single duplicate screen on both monitors, java not working, settings moved/rearranged/disappeared with no way of finding them (eg hot corners)). I'm sorely tempted to do a totally clean re-install.
Thanks for taking the time to help.
