Hi all.

Here:

https://askubuntu.com/questions/109505/how-do-i-access-an-external-hard-drive-plugged-into-my-router

the problem seems to be solved, but not for me... I plugged a USB storage
pendrive into my ADSL internet router but don't know how to access it. I tried
putting in /etc/fstab something like:

//192.168.1.1/USB_storage /mnt/public cifs guest 0 0

with no result: when I do `mount -a' it says:

mount error(115): Operation now in progress
Refer to the mount.cifs(8) manual page (e.g. man mount.cifs)

. Please help whoever can.

Thanks in advance,

Rodolfo

Is this the correct share to mount? Try "smbclient -L 192.168.1.1" to see
what shares are available.

Try running smbmount directly and see if it gives more information:

# mount -t cifs //192.168.1.1/USB_Storage /mnt/public --verbose -o guest

FWIW, 0 is not 1.

Maybe try again, but with the correct ip address?

Sorry... But the result is the same:

$ smbclient -L 192.168.1.1

WARNING: The "syslog" option is deprecated
Enter rodolfo's password:

Connection to 192.168.1.1 failed (Error NT_STATUS_IO_TIMEOUT)

If I put 192.168.1.2, instead, I get something more:

$ smbclient -L 192.168.1.2

WARNING: The "syslog" option is deprecated
Enter rodolfo's password:

And also:

# mount -t cifs //192.168.1.2/USB_Storage /mnt/public --verbose -o guest
mount.cifs kernel mount options: ip=192.168.1.2,unc=\\192.168.1.2\USB_Storage,user=,pass=********

mount.cifs kernel mount options: ip=192.168.1.2,unc=\\192.168.1.2\USB_STORAGE,user=,pass=********
mount error(6): No such device or address

Refer to the mount.cifs(8) manual page (e.g. man mount.cifs)

Besides, pointing the web browser at 192.168.1.1, the usb storage is seen in
the Admin menu. Does all this suggest us anything useful...?

Thanks,

Rodolfo

Yes, this confirms that 192.168.1.1 is the address of your router. An IP
address typically identifies a single device. If you are looking to talk
to the USB device attached to the router, there's no point talking to
192.168.0.1 or 192.168.1.2 - that's like saying "I couldn't find my
laptop, but I walked into my neighbour's house and they had a laptop so
it must be the right one"

That's not strictly true. Years ago I had an (awful) Netgear router that would provide a samba share for an attached USB device and by defaualt it did so on a separate IP.

All right, but to do then now...? Why no response comes from 192.168.1.1?

To be fair, a response *is* coming from 192.168.1.1 (case 2 above), and
this response is "NO, you are not allowed"). As opposed to case 1, where
the client gives up (...TIMEOUT) after a while of silence.

So you'll have to fix the permissions on your CIFS server now. No, sorry,
I have no idea on how to do that, but perhaps the router's web "GUI" has
something on this.

First of all, I had to set the USB drive as a `Managed partition' from the
router web GUI. Secondly, its right address was `//192.168.1.2/Shared' and not
`//192.168.1.1/USB_storage'. With these corrections, and the following line:

//192.168.1.2/Shared /mnt/shared cifs rw,user,noauto 0 0

in /etc/fstab, I can now properly mount the USB derive as a normal user simply
with:

$ mount /mnt/shared

and hitting `Enter' when prompted for password. This said, and thanked all who
helped, I now wish to automatic mounting at start up but don't manage to.
Googling around I found many suggestions but no one that helped me. On another
machine of mine, an old Acer Aspire One netbook, it works by putting in fstab
the following:

//192.168.1.2/Shared /mnt/shared cifs rw,user,password=mypassword 0 0

where `mypassword' is *any* word. On my desktop Lenovo, instead, it does not
work. Please, any suggestion?

Thanks,

Rodolfo

I'm revisiting now this old thread in which I solved my problem... Now I have
the problem again with my new router Zyxel VMG8823-B50B. I can access the USB
stick via Nautilus:

$ nautilus smb://192.168.1.1

but don't manage to mount the USB stick. In /etc/fstab I have:

//192.168.1.1/mnt/usb1_sda1 /mnt/shared cifs rw,user,noauto 0 0

but it asks for password and fails:

$ mount /mnt/shared/
Password for rodolfo@//192.168.1.1/mnt/usb1_sda1: ************
mount error(112): Host is down

Refer to the mount.cifs(8) manual page (e.g. man mount.cifs)

Please help whoever can.

Thanks,

Rodolfo

I use gnome-disks to mount and unmount USB sticks directly plugged in to
my machine, which is running Stretch.
