1. Going mad trying to mount old NAS
   

   I was recently given an old NAS (Omninas KD20). This model was discontinued in 2015 and I have spent the last three days trying to mount it in a Linux container to no avail. I am very close to just chucking it in the bin!

   Here’s what I have tried:

   I’ve created a directory call test on the NAS which is public. I can connect to this in Windows (however I had to re-enable SMBv1). I can connect to the share in Linux with smbclient and also with Gigolo. I cannot seem to mount the share using the mount command.

   Code:

   $ sudo mount -t cifs //192.168.1.56/test/ /home/cifs/ -o username=john,password=john
   mount error(112): Host is down

   I thought maybe it’s the SMBv1 issue? dmesg contains an error mentioning dialect level, so let’s try that.

   Code:

   $ sudo mount -t cifs //192.168.1.56/test/ /home/cifs/ -o username=john,password=john,vers=1.0
   mount error(1): Operation not permitted
   Refer to the mount.cifs(8) manual page (e.g. man mount.cifs)

   There is no error after this command in dmesg.
   Very weird because smbclient works!

   Code:

   $ sudo smbclient -L 192.168.1.56/test -U john
   Enter john's password:

           ---------            -------
           WORKGROUP            OMNINAS-434369

   I can also access the share using Gigolo on another laptop. I simply type in the IP address, check ‘Windows Share’ and then it can connect. I can then open it in a terminal and see the files.

   This is incredibly frustrating because I can’t do the one thing I need to do with this Does anyone have any ideas?!

2. Re: Going mad trying to mount old NAS
   

   I have also tried to mount with the sec=ntlm option to no avail:

   Code:

   $ sudo mount -t cifs //192.168.1.56/test/ /home/cifs/ -o username=john,password=john,vers=1.0,sec=ntlm
   mount error(1): Operation not permitted
   Refer to the mount.cifs(8) manual page (e.g. man mount.cifs)

   I have also added the following to /etc/samba/smb.conf:

   Code:

       # Allow access to SMB1 shares on other servers
       client ipc min protocol = NT1
       client min protocol = NT1
   
       # Allow access to shares on other servers ONLY via SMB1
       client ipc max protocol = NT1
       client max protocol = NT1
   
       # Allow access to shares on this Samba instance via SMB1
       server min protocol = NT1
   
       # Allow access to shares on this Samba instance ONLY via SMB1
       server max protocol = NT1

   However I still receive ‘Operation not permitted’.

   I tried supplying a uid to no avail
   smbtree -d3 didn’t contain any errors either.

   I tried vers=1.0,sec=ntlm and also sec=none and nounix. All combinations resulted in ‘Operation not permitted».

   https://ubuntuforums.org/showthread.php?t=2375117
   This guy’s issue was solved by adding vers=1.0 which I already have

   Unfortunately this issue was resolved by simply adding sudo, which I am already using

   I nmaped the NAS to make sure the issue isn’t something on that side of the equation. I didn’t see anything obvious but here’s the output just in case:

7. Re: Going mad trying to mount old NAS
   

   I wonder if this was not shut down while it was being run on Windows. If the machine that was using it did not have fast boot disabled, that might be the cause. Can you connect it to a Win machine (with Fast Boot disabled and then shut it down and see if it is then released?

8. Re: Going mad trying to mount old NAS
   

   Interesting idea! I opened the web browser for the NAS on a Windows machine and clicked shutdown, I heard a beep from the NAS and it turned off and was no longer accessible. I turned it back on with the power button and verified it was back on by opening the web admin page. I then tried to mount it again and got the same error «Operation not permitted»

   Is that what you meant by connect from a Windows machine and shut it down? I’m not sure how to check if FastBoot is enabled.

   Is there a way to find the exact error here? Operation not permitted isn’t very illuminating.

9. Re: Going mad trying to mount old NAS
   

   I think I have figured it out. I’m using a Ubuntu LXC container on a Proxmox host. When I use an Ubuntu VM, the NAS mounts fine. No idea how to solve it so I’m just going to switch to the VM.
