ReadyNAS Duo (Sparc) needs SMBv2 or higher

Hi
I have the ReadyNAS Duo V1 (Sparc). Since the Microsoft 2017 Fall Creator's Update for Win10, SMBv1 is obsolete and I can't see it anymore on my main Windows PC (although I can on a second, older machine). It needs to support SMBv2 or v3. I read that this can easily be done by adding the line:

 

server min protocol = SMB3

 

to the end of /etc/frontview/samba/smb.conf.overrides 

(according to https://community.netgear.com/t5/Using-your-ReadyNAS/SMB-1-0-Given-Wanna-Cry/td-p/1283738).

However, I have absolutely no idea how to do this. I installed a 'shell' from here (https://kb.netgear.com/24546/Add-ons-for-RAIDiator-4-1-3-Sparc) but there are no instructions on how to access it, or if I did, how to find, edit and save the above mentioned document. I know nothing about Linux I should add at this point, but I'm game for trying if I had the instructions.

The last point of note is that the last supported version of Radiator is 4.1.16, so I'm not sure if the version of "samba" that comes with it would support the suggested edit of "server min protocol = SMB3" or even SMB2.

 

Is there a patient knowledgeable person out there who can tell me if I can make my old NAS continue to talk to Windows 10, and how I achieve this seemingly essential small edit? Thank you so much!!!

Let's start here.  If you go into "turn windows features on and off" you should see an option for the SMB1 client.  So you can still re-enable that option.

 

If you see an NFS client in your windows system, you could alternatively install that, and then turn on NFS file sharing on the NAS.  That might be a better long-range solution.

 

Enabling an ancient experimental mode in your duo v1's SAMBA is probably not a good approach.

Re: ReadyNAS Duo (Sparc) needs SMBv2 or higher

The Duo has experimental SMB2 support which is disabled. It's beyond the security support period so I don't anticipate there being any further firmware updates for it at all.

 

If SMB2/SMB3 support is important to you you may wish to consider getting a new ReadyNAS.

Re: ReadyNAS Duo (Sparc) needs SMBv2 or higher

Hi

Unfortunately no option for turning on NFS is present. I should state that I'm using Windows Home edition (on the 2 PC's on my little 'network') so perhaps NFS is an option on the Pro or some other edition of Windows. Anyone aware of any 3rd party software I can get that might fix the issue and introduce NFS?

 

Meanwhile I have an interesting update. My older PC (call it PC1) has the so called Fall update of Windows 10 too, and yet it can still see, read and write to the ReadyNAS Duo as perfectly as ever. PC2 meanwhile (the newer hardware), cannot do anything - the NAS has become totally invisible inaccessible from there. Some people have found that creating a network connection using the IP address of the NAS gets around the problem, but that's not working for me. Having one PC see the NAS isn't quite the fix it first appears to be. Imagine my backup routine for PC2 now: backup PC2 to PC1 (assuming thee's enough space on the older machine. Then move the backup off PC1's disk to the NAS. That's looking like a 24 hour operation now.

 

Upgrading the NAS isn't quite an option either (I'm on a severely limited budget). I feel angry and let down by Netgear for not providing better support.

 

I appreciate your remarks (and those of others) on how the old experimental Samba mode isn't to be celebrated, but I may be looking at any port in a storm at this point. I'd still like someone to tell me how to access the shell I installed. Besides, if I could figure out how to access the shell I could do the text edit to the config referenced elsewhere in these forums and linked to in my original post I think. It would be an experiment itself. If it didn't work I could always back out of it and stick with the bizarre 'daisy chain' method of accessing it via PC1 as I seem condemned to do now anyway. 

 

Thank you.

Re: ReadyNAS Duo (Sparc) needs SMBv2 or higher

Assuming the "shell" you installed is "Enable Root SSH Access", you need to install Putty on your PC.  Use the default settings in Putty for an SSH connection and type in the NAS IP address.   When the CLI opens, log in as "root" using the admin password.

 

But from there, you'll still need to know how to navigate the Linux file system and use VI to edit the file.  Google can be your friend there.  And, BTW, you will have to set the min protocol to SMBV2, as your NAS has no SMBV3 support.  Given that SMBV2 is only experimental in your version of Samba, issues are possible.

 

But is enabling SMBV1 not an option in your Windows version?

 

Also, for NFS, open an elevated command line on the Windows machine and execute

dism /online /get-features | more

and see if these are listed:

 

Feature Name : ServicesForNFS-ClientOnly
State : Disabled

Feature Name : ClientForNFS-Infrastructure
State : Disabled

Feature Name : NFS-Administration
State : Disabled

 

If they are, you can use 

dism /online /Enable-Feature:NFS-Administration

and repeat for all the above features to turn on NFS even though it's not listed in the enable features GUI.  I don't have a Home version install to check on.

Hi Sandshark
Thank you for your amazingly detailed response. You are a gentleman and a scholar! I just wanted to thank you ahead of trying your advice as I will be away from the PC's for nearly a week & so unable to try your suggestions, but I'll give you feedback on what happened in due course.

Thanks again!

Enabling the SMB1 client in Windows should still be possible, and I recommend doing that instead of enabling the old experimental flag.

Re: ReadyNAS Duo (Sparc) needs SMBv2 or higher

Today got an error message on a Win 10 (32) bit that it can't access the Ready Nas Duo any more. I think we definitely need SMB2 support from Netgear for our Readynas devices. There was a message, that it was disabled from Microsoft because they are considering not secure any more and pronoe to ransomware attacks!

 

Please asist - thank you!

Re: ReadyNAS Duo (Sparc) needs SMBv2 or higher

The Duo was replaced in our product lineup way back in 2011. It's well beyond the security support period.

 

You could re-enable SMB1 support on your PC.

Re: ReadyNAS Duo (Sparc) needs SMBv2 or higher

I was in the identical situation but with Windows 10 (64). The only option was to 're-enable SMB1 - Google it, it's quite easy to do. I believe the security threat is greatly over stated. I use Avast anti-virus (don't use a Russian system!) & also a separate anti rabdsomeware system, both free, and I have been fine. No problems! Good luck with it!

Re: ReadyNAS Duo (Sparc) needs SMBv2 or higher

Thanks - yes, was not too difficult to reenable, but somehow worked more just by chance because there are not many easy instructions around because in my case it was actually still enabled.

 

Yeah - it's always the same. They sell old stuff for cheap and then the cut support and you have to buy a new one soon ... not very nice. Not sure if my next one will be a Netgear NAS.

Re: ReadyNAS Duo (Sparc) needs SMBv2 or higher

Personally I don't see a bait-and-switch here.  Netgear stopped selling the duo v1 a long time ago - back in 2011.

Re: ReadyNAS Duo (Sparc) needs SMBv2 or higher

SMB performance is already pretty slow on the Sparc models. If you were to enable SMB2 and use that it would presumably be even slower.

 

The hardware in the Duo is the same CPU and memory (RAM) spec as a model we released way back in February 2006. It's old.

Re: ReadyNAS Duo (Sparc) needs SMBv2 or higher

I just performed the NFS command line items, and it all seems to work now on my old NV+.

Question:  Did I just open up the gates of hell, in terms of security holes on my PC, now that I did this?

 

Thanks,

Re: ReadyNAS Duo (Sparc) needs SMBv2 or higher

Hi
Thank you for your question. While it would be irresponsible of me (and beyond me jurisdiction) to promise you no vulnerability from this step, I think I can offer you some substantive assurances.

First, I was told in my turn by other online contacts that this step by Microsoft was excessively and perhaps absurdly cautionary. It's beyond my technical specialism to comment on that, but I can tell you I decided to trust it. I sort if had no choice since as you know, the NAS becomes near useless without it. So I went for it.

The more important thing I can share with you from first hand experience is that after re-enabling SMB for about a year now, I have had no problem at all. Not even a blip, let alone Hell's legions. In short it looks like that advice was correct. Blocking SMB really was a bit of a neurotic over-reaction. Re-enabling it has had no adverse consequences whatsoever. Make sure you have a good virus checker ( I use Avast free version) plus Windows firewall, as a matter of course. Good luck, and enjoy your Nas for a good few.more years yet!

Re: ReadyNAS Duo (Sparc) needs SMBv2 or higher

Well, here's the thing... I never enabled SMB2. I just ran those 3 command line commands that "turn on" (?) The NFS functions. Then I could access the shares. That's why I was wondering about security.

Hi
Same difference really. I just re-enabled. That's what I assumed we were talking about.

Well, what you did was install the NFS client.  When SMB negotiation fails with the Duo, Windows tries NFS.  Since that is working, NFS must be enabled on the shares in the duo.

 

Both NFS and SMB 1.0 are considered to be insecure protocols.  Both also are normally run on a local network (not over the internet), which reduces the security risk.   I'd say the risk is small on a home network, but you should have the PC set up to disable file sharing when you are on public networks.
