Connecting to the NAS

[Phil Binner]

I have a Dlink NAS DNS-325. When I browse files it's there, absolutely fine, but when I want to connect from an application, such as Thunderbird (or anything else) the network is just not available. This is not just the NAS that's not available, it's the whole network, but the NAS is what concerns me at the moment.

I have been told I need to mount the NAS at startup, and have been directed to a site "http://ubuntuforums.org/showthread.php?t=249889", which instructs me to run the commands

$ sudo apt-get update
$ sudo apt-get install nfs-common

Following is the result:

Then tried to view the location:

bigbin@Bigbin-Ubuntu:~$ showmount -e 192.168.1.73
clnt_create: RPC: Port mapper failure - Unable to receive: errno 111 (Connection refused)

Then tried to mount the NAS in a directory called nfs:

bigbin@Bigbin-Ubuntu:~$ sudo mkdir /nfs
[sudo] password for bigbin:
bigbin@Bigbin-Ubuntu:~$ cd /nfs
bigbin@Bigbin-Ubuntu:/nfs$ cd /
bigbin@Bigbin-Ubuntu:/$ sudo mount -o soft,intr,rsize=8192,wsize=8192 192.168.1.73:/volume1 /nfs
mount.nfs: Connection timed out

Can anyone help please. This is one of the problems preventing my migration from Windows, though by no means the only one.

Does the NAS provide any logs for diagnosis?

Does the NAS have "no_root_squash" set as an NFS option? Without that, root cannot mount an NFS share.

[Phil Binner]

I'm afraid I can't answer those questions. The NAS is a 2 disc RAID system, but when I log on I don't see any NFS settings. Could it be that it doesn't use NFS.

All the log shows for today is starting and stopping the fan.

All I can tell you for certain is that I have no problem accessing the NAS frof the file browser, but it is not accessible from anywhere else.

[steeldriver]

As a first step you could install nmap on the client and at least probe the server to see if the usual nfs and rpcbind ports are open, for instance on my little Netgear ReadyNas I get

$ nmap -A -T4 192.168.1.127 | grep -e '^111' -e '^2049'
111/tcp   open  rpcbind     2 (rpc #100000)
2049/tcp  open  nfs         2-4 (rpc #100003)

[with the ReadyNas I *can* actually ssh into it and look at its /etc/exports file directly but that's an unsupported hack - I suspect you may be limited to whatever you see via your NAS's standard web interface]

[Phil Binner]

I installed nmap but couldn't find it to run it. The software ncentre says it's installed, but it isn't in the all applications list from Dash Home. So then I installed the GUI frontend zxenmap and ran that. It complained that I wasn't a root user, but ran anyway. Following is the output:

Is that any help.

[steeldriver]

OK well I'm *not* an expert on these kinds of things but that looks to me like it is only sharing via SAMBA - you'd need to look at the Dlink documentation to see if it's possible to turn on nfs sharing, if not you should be able to mount using cifs (SAMBA) after installing the cifs-utils package, e.g. for a public (no authentication required) share:

$ sudo mkdir -p /mnt/nas-01/public
$ sudo mount -t cifs //192.168.1.127/public /mnt/nas-01/public
Password:
$ ls /mnt/nas-01/public/
Downloads  Program Files  setup  Software  Thumbs.db
$

or for a private share

$ sudo mkdir -p /mnt/nas-01/home/myuser
$
$ sudo mount -t cifs -ouser=myuser,pass=xxxxxxxx //192.168.1.127/myuser /mnt/nas-01/home/myuser
$
$ ls /mnt/nas-01/home/myuser/
Misc  Other  Visual Studio 2008
$

You can also use a credentials file I think - after installing cifs-utils you can refer to the man page for all the options / syntax

man mount.cifs

Oh and fwiw you would run nmap direct from the command line after starting a terminal (Ctrl-Alt-t)

[gordintoronto]

You just need to do this once: make sure your file manager is set to display hidden files. In your Home folder, scroll down to .gvfs and right-click on it. Select "Make Link." The Link will not be hidden, drag it onto your desktop.

After making sure the drive is mounted, from your application's save dialogue navigate to Desktop, select "Link to .gvfs" and the network drive will appear in it. One more double-click and you can save.

[Phil Binner]

Hi. Thanks for that. After a very busy time I have returned to Ubuntu and applied the fix Gordintoronto provided, and it did work after I had selected the NAS inside the link to .gvfs. Only until I rebooted , though. Have I missed something or is there something else I should do to prevent me having to prime .gvfs each new start up.

[Phil Binner]

next tried steeldrivers option. The results are following:

bigbin@Bigbin-Ubuntu:~$ sudo mkdir -p /mnt/d-link-nas/public
[sudo] password for bigbin:
bigbin@Bigbin-Ubuntu:~$ sudo mount -t cifs //192.168.1.127/public /mnt/d-link-nas/public
mount: wrong fs type, bad option, bad superblock on //192.168.1.127/public,
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

bigbin@Bigbin-Ubuntu:~$

My problem is that I am really a GUI man, and only moderately competant at that. Every time I venture forth into the terminal it's like I'm in a foreign country. Any more help would be appreciated.

[steeldriver]

Haven't re-read the whole thread, but if you want to go the CIFS route then make sure you have the cifs-utils package installed (it isn't by default) and try again

sudo apt-get install cifs-utils

sudo mount -t cifs //192.168.1.127/public /mnt/d-link-nas/public

Obviously replace 192.168.1.127 with your actual NAS IP
