B2 NAS has disappeared

[Fred Hopper]

I have just upgraded to the B2B version of the Brenan OS (see below).

I can see my device interface OK in the browser  (http://192.168.0.9/original.html#) and the B2 DLNA Server seemed to work OK. (I have turned this off and saved)

However my PC's (Windows 10 OS build 18363.900) NAS connection to the Brennan no longer works. (I have checked that NAS is turned on at the Brennan end and saved this). 

Any ideas?

Thanks

Fred

PS - I can PuTTY into the Brennan just fine - but no way can I connect to it as a NAS.

[No1Mellenhead]

If you are using Windows 10 you may need to turn on SMB1.0 - please see this post - link - for details.

[Peter Lowham]

Hi Fred,

If you putty into your B2 try the following, if you haven't already done this.

#cd /etc/samba

#ls -la

If NAS is switched on, you should see a file called 'smb.config' listed.

If the file is not there, then run the 'Start NAS' option in the 'Maintenance' menu.

Regards,

Peter.

[Fred Hopper]

Hmm - did I do all I should have?

cause it did not work

[Peter Lowham]

Hi Fred,

All of your data does look normal, I can't see anything amiss here.  I'm running on the same version of B2B software as you are, and running servers and clients on a mix of Win 10 and Win 7 and it's all working fine.

If you putty back in to the B2 and do

#cat smb.conf

Do the first two lines show as:

[global]

netbios name = BrennanB2

I would be almost certain that this is the case, but just to be sure ......

Regards,

Peter.

[Fred Hopper]

Hi Peter,

no, that is not the case, this is what I see

I found the Vi editor works on the B2 so I added the line thus:

Did I do OK?

I will see if it has corrected the problem.

If it does than the smb.conf file in 

is incorrect and more people will get this problem......any how I will now reboot and see if it works.

Fred.

[Fred Hopper]

Hi Peter,

Alass adding the "netbios name = BrennanB2" line has not corrected the problem.

Please note when I turned on the DLNA option - that Did Work.

AND

I have had the NAS going (very well!!) in the past (not needed to use it over the past few months).

Sigh!

Fred

[Peter Lowham]

Hi Fred,

I'm not sure what is happening here.  I'll reflash an SD card with Nov 6 2019 and see if I can work out what is going on.  Enabling the DLNA feature should not have any diect effect on the NAS function but who knows?

Regards,

Peter.

[Fred Hopper]

Thanks Peter.

Unfortunately I did not keep an image of that version of the B2 OS. 

To help I will reflash my OS (tomorrow) with the latest image, do a web upgrade and then  JUST turn on NAS (no DLNA) to see if that corrects the issue.

Fred

[Peter Lowham]

Hi Fred,

No problem; I would just like to get to the bottom of the problem!

Regards,

Peter.

[Fred Hopper]

Hi Peter

Progress report.

This morning I re-flashed the OS, set up WiFi, did a Web Upgrade, ran a scan, saved and rebooted. I then turn on NAS and saved an rebooted (hand controller info confirmed that NAS was on and DLNA was off).

Tried NAS from PC = No luck.

Then proceeded to PuTy in and change the 'smb.config' file to include the "netbios name = BRENNANB2" line. Went back to the B2 and saved and rebooted.

This DID result in a change see next message

[Fred Hopper]

[Fred Hopper]

Thus the B2 is visible in file manager but one can not open it.....ARGUHH!!!

[Peter Lowham]

Hi Fred,

The error reads 'cannot access \\BrennanB2' rather than 'cannot access \\Brennanb2\music'  Is your Windows network map entry fully stated? '\\BrennanB2' is a system name and 'smb' needs a folder name, so I would check that out.

Other items to check are:

Putty in to /etc/samba and use the command:

#ls -la

Are the permissions on 'smb.conf'  showing as follows:

-rw-r--r--    1 root     root           913 Jul  9 12:22 smb.conf

If not use the command:

#chmod 644 smb.conf

This will adjust your smb.conf permissions to match those on my file.

I have just remembered why I use the smb global parameter 'netbios name = xxxxxxxxx'.  I actually use 'netbios name = BrennanB2-1' ,  'netbios name = BrennanBB1' etc. because I have multiple Brennans on my network, so I needed to rename them for smb presentation.  You should be able to remove this line from your smb.conf file if you have one Brennan on your network as it defaults to 'BrennanB2' if the parameter is not set..

Regards,

Peter.

[Fred Hopper]

Hi Peter

as was

after the chmod

It did not seem to change anything.

even the 1st jan 1970!!

yours is bigger too

--------------------------------------

Are the permissions on 'smb.conf'  showing as follows:

-rw-r--r--    1 root     root           913 Jul  9 12:22 smb.conf

------------------------------------------------------------------------

Regarding the netbios name - it cant hurt by having it (I do only have one B2) but I will remove it.

and try again

[Fred Hopper]

Hi Peter

see

[Fred Hopper]

Hi Peter,

I am assuming that the second "Windows Security" popup is requiring the B2 infor and not the Windows ID and Password?

Please note I have set up my PC so that my login does NOT have Administrator permissions.......I don't think that this should matter but tell me if you think it does (I am not getting a type in the windows Admin password message at any point).

Fred

[Norm Glennard]

Hi Fred

Have you tried substituting the IP address in place of ‘brennanb2’?

Norm

[Fred Hopper]

Hi Norm,

Thanks for taking an interest.....I have hardly any hair left.....

Yes I have tried \\192.168.0.9\music 

(I have set the B2 up on my router to have a fixed IP address.)

I feel it is a problem caused by Windows updates.

because I had the By mapped in the past see

the "music" folder was the NAS view of my B2. (this no longer work either).

Fred.

[Norm Glennard]

I had something similar yesterday. I disconnected the previous mapped drive and rebooted before I re mapped.

I have the latest updated Windows 10 but the network has always been flaky.

Norm

[Peter Lowham]

Hi Fred,

The error message is now showing the 'music' folder in the connection string which is good.

There are two items that I would change:

1. In the 'Map network drive' window, untick the 'Connect using different credentials' box.

2. In 'Enter network credentials', tick the 'Remember my credentials' box.

My 'smb.conf' file is bigger than normal because I have defined additional B2 level folders and files that I want to access through Windows, so I have created other entries in 'smb.conf' to enable that to work (access to 'b2db' and 'b2settings' files, access to 'usba' and 'usbc' folders etc).

Regards,

Peter.

[Daniel Taylor]

If the problem is the result of a Windows update, maybe you have to enable SMB 1.0 again.  (?)

[Mark Fishman]

My experience with Windows 10 and my B2 is that, when inputting the credentials (username and password) for the B2, you have to tell Windows to authenticate that set of credentials against the B2, not against your local computer. Thus you must preface the username "root" with the name of IP address of the B2, a backslash, THEN the username ("root").

For example: when prompted to provide username for the B2, I would type

192.168.0.5\root

If you just type

root

at that prompt, Windows can look for a root account on your computer and discover that it can't find one.

Whoever told Microsoft they knew how to design a user interface was an idiot.

[Fred Hopper]

Hi Mark

Tried what you suggested - sorry it makes not difference :(

I have even upgraded my router (I it was getting old and flakey) even that has made no difference.

Thanks for the suggestion though,

Fred.

[PMB]

Hi Fred,

Have you checked that SMB1.0 is enabled on the computer - I have heard that sometimes Windows updates turn SMB off?

Looking at your computer screen shots above I can only see 6 characters for the password - brennan is 7.

[Mike]

I have been watching this post with interest as I have exactly the same problem.  Today my NAS stopped showing on  my PC and I cannot get it to appear again having tried all the suggestions raised on this forum.  So annoying because I am a long term user of a B2 and never had problems accessing it on my PC as a NAS drive.

Mike

[Peter Lowham]

Hi Mike,

Micosoft is going through one of it's update phases currently which normally causes serious havoc to end users.  I'm using NAS extensively to my B2s and BB1 and I've had to make adjustments to the Windows environment and then remap drives and network locations from time to time.  The NAS functionality at the Brennan end has been very solid and reliable so I reckon you should look at the PC end.

If the status screen shows 'NAS On' then it's very likely that the problem is at the PC end.

Regards,

Peter.

[Fred Hopper]

Hi Mike

Frustrating isn't it ! I too have been using the B2 as a NAS from Windows for years with no problem. Then suddenly it is not there.

I have tried everything I know to get it back - followed all the advice here, researched it on the web and tried suggestions from there.....but no luck yet.

I thin that Peter Lowham (see below) is correct this is not a Brennan problem, it is something Microsoft has done !!

I expect there will soon be more of us on this thread.

Cheers

Fred

[Chris Jones]

Hi I have fully patched\updated both my Windows 10 devices (version 2004) and both connect to the B2 NAS (Still have the issue with slowness but that's down to the Pi as they have very slow I/O)

My 2012r2 server also connect without issue, are we sure its not an issue with the latest B2 software as I am still running software dated 2nd June.

hope this helps

Chris

[PMB]

Hi All,

My laptop running Windows 10, Version 1903, is seeing the B2 (with B2B July 21st 2020 software) OK. I do have SMB1.0/CIFS Client enabled.

Paul

Brennan Support.

[Mike]

My PC did a windows update this morning and all is now well with accessing the B2 as a NAS drive.  The update is KB4565633

Mike

[Fred Hopper]

My PC already has update KB4565633 installed.

[Fred Hopper]

OK, Evereone,

I decided to try and eliminate the B2 as the source of my problems. I have an Amazon Fire tablet, on this i loaded the free version of the "ES File Explorer" app. Using this I can see the BRENNANB2 as a NAS and can access an play tracks of music from it. Therefore the B2 is functioning as an active NAS on my home LAN.

This means that my problems are all Windows 10 related.

At the moment I have SMB turned off :-

and In file manager

this is what I see/get

I will now turn on SMB and report back

[Peter Lowham]

Hi Fred,

You will probably fix the problem by enabling the 'SMB1.0/CIFS Client' item.

Regards,

Peter.

[Fred Hopper]

Further work

SMB installed see :-

Now the B2 is not visible in File Manager see :-

and when I try a manual connect thus

I get this

Sigh!!!

I think that as Microsoft are deprecating (and replacing) the use of SMB and I saw more activity without it, I will go back to that state. 

I wonder if it is a Windows Defender / Firewall issue....

I am not a Defender aficionado - an pointers greatly appreciated.

Fred.

[Mark Fishman]

(a) I assume you are absolutely certain that the IP address you are using for the B2 is the one that the B2 has currently acquired?

(b) perhaps if  you took out the double backslash before the share, as the prompt suggests:

    \\server\share

Windows would be more cooperative. No guarantees, of course.

-- m.

[Fred Hopper]

Hi Mark

Regarding the IP address,

Yes I have made the BRENNANB2 have a static IP address of 192.168.0.23 using the facility to do this on my router, I also see the B2's web page when browsing to that address and can log on to it there using PuTTY .. see

Regarding your second suggestion:-

(b) perhaps if  you took out the double backslash before the share, as the prompt suggests:

    \\server\share

Windows would be more cooperative. No guarantees, of course.

I think the leading double \\ is required ?

Fred.

[Mark Fishman]

The leading double backslash, yes -- that's before the server (name or IP). Your screen capture shows a double backslash before the share name also, i.e., between the IP address and "music". That's wrong.

[Fred Hopper]

Woops!!

I missed that mistake (finger trouble).

Will have another go.

Fred.

[Fred Hopper]

OK Mark, 

here it is with the mistake corrected

1)

 

[Fred Hopper]

Also for the last post I have turned of Defender's Firewall on my home (private) network)

[PMB]

Hi Fred,

You originally said that you had updated to B2B software - I assume you repro'd the SD Card - can you go back to B2 software as a test?

Paul

Brennan Support.

[Fred Hopper]

Hi Paul,

I did upgrade (by overwriting the SD Card) - however if you can point me at an image of the pre B2B software, I can easily flash a spare SD with it and pop that in (I have an old sticky out SD slot on my B2) and try things.

You did note that at present I CAN see the B2's NAS on my Amazon Fire tablet (using ES File Explorer app)  - AND - I can PuTTy into the B2 just fine.

To me this sort of eliminated the B2 as the problem?

Cheers

Fred.

[PMB]

Hi Fred,

I think you are right in thinking it's not a B2 problem but there is a link to B2 software under 24th December 2019 0n the Latest Software page - link - if you don't mind trying it.

Paul

Brennan Support.

[Fred Hopper]

Morning Paul

The link you sent was for USB stick drive software.

I will be writing a new SD card with B2 software on it (an image)

The only link I can see for that is this one

https://www.brennan.co.uk/itemcontent.php/content/Techy

"Then download the image file from here

Plug your target SD card into your PC"

That link leads to the B2B version only - I need a link to the B2 software image to "go back".

Cheers

Fred

[Mark Fishman]

Guys, pay attention: Fred wants to go back to the Linux kernel used for the B2 version of the software, BEFORE the B2B (bluetooth upgrade) kernel was released. He needs the "create a new SD card" IMAGE for the (old) B2 SD card, not just the Brennan application file. The B2B IMAGE file is hosted on Google Drive (e.g., https://drive.google.com/open?id=1iZPdSlQ7YPgX5iWN4YXRNM6-NKLPQYiA for the current B2B SD CARD IMAGE) -- presumably the previous B2 IMAGE file was hosted seomehwre on Google Drive as well.

This is NOT the same file that Daniel and PMB are referring to, and apparently even the current Brennan application has diverged into two streams depending on whether you have the B2B kernel or the previous B2 kernel.

[Daniel Taylor]

Thanks, Mark.  You've nailed the crux of the matter, which I failed to notice.  I'll delete my post, since it's not helpful.

[Daniel Taylor]

Ii have two zip files saved that I suspect are what's needed to build an SD card from scratch:

B2Nov102017.zip   671,352 KB

B2BNov2019.zip      77,472 KB

The first is obviously for B2, the second for B2B.  I'm very curious as to why the filesizes are so very different.  It makes me think that one or the other is wrong.

[Daniel Taylor]

I have two zip files saved that I think are for building an SD card from scratch:

B2Nov102017.zip   671,352 KB

B2BNov2019.zip      77,472 KB

The first is obviously for B2, the second for B2B.  I'm curious as to why there's such a big difference in the file sizes.  Makes me think that one or the other is wrong.

[Fred Hopper]

Hi Daniel,

Yes I think the 

B2Nov102017.zip   671,352 KB

that you have is the image I need.

Could you get it to me via my email ?

Regadrin the size of your B2BNov2019.zip file, the one I downloaded form the Brennan site (and used to image my current SD card) look like this - it seems a bit bigger than yours!

[Daniel Taylor]

I'm not sure what will happen to such a large file attached to an e-mail.  But I will give it a try.

[Peter Lowham]

Hi Guys,

Mark is correct in his assertions above.  I have looked on the Breenan website but cannot find the B2 base 'img' file.  I do have a copy of this file in ZIP format, dated Jan 04 2018.  Once you have flashed this, you can Web Upgrade directly to July 21 version (I have just tested that here at home and it works OK).

I have placed this file in my Public Dropbox folder, at the link below.  If you download this file, hopefully this help you.

https://www.dropbox.com/s/quonkrjqugduwmc/B2%2020180124.zip?dl=0

Let me know how you get on.

Regards,

Peter.

[Daniel Taylor]

When I tried to send it as an e-mail attachment via Gmail, I got this message:

It's currently uploading.  Let us know how it turns out.

[Fred Hopper]

Thanks Peter, and Daniel

I have downloaded yours Peter and it is being flashed as I write

:)

Fred

[Peter Lowham]

Hi Fred,

Great stuff!  When you first run 'Info' the version will show as 'Version Jan 4 2018' but it is the 'B2' version.  It was developed before the naming convention was introduced.

It will show correctly when you do a Web Upgrade as 'Version B2 Jul 21 2020'.

Regards,

Peter.

[Fred Hopper]

OK - first report back on using old B2 images

1) the actual (un web-upgraded version from Peter) = No change in NAS observed behaviour from Windows.

2)Web upgraded version from Peter = No change in NAS observed behaviour from Windows.

I think that we can definitely rule out attributing the problem to the B2

 Thanks for your help in achieving this

(PS I will save an image of the Web upgraded version from Peter if ever you need one)

Fred

[john Henrick]

I have 2 windows 10 units both with smb1.0 enabled and I can only see myb2's or Nas drives with the one pc I am investigating why my feeling is. Windows patches somewhere

[Fred Hopper]

All help, brains, eyes on this is MUCH appreciated.

Thanks

Fred

[fred.w....@gmail.com]

YIPPEEE !!!

I have finally resolved this issue: My B2's NAS is back!

This has been ALLOT of pain for me - to eliminate, narrow down the issue I have

1) Checked I could see the B2 Nas on an Android device (I could)

2) Replaced my router (it needed replacing anyway) (No Change)

3) Did all that was recommended by the kind people on this thread (No Change)

4) Upgraded my Windows 10 to Pro (ouch!) (No Change)

5) began researching and testing on and off for weeks until I go a fix that worked. The fix is (apart form all the option in the thread above)

a) Open the "Group Policy Editor" from an Windows Admin account

b) go to the "Computer Configuration\Windows Settings\Security Settings\Local Policies\Security Options" path

c) find the entry "Network security: Restrict NTLM: Outgoing NTLM traffic to remote servers"

d) change its value to "Allow all" from the options.

e) save

f) exit the utility

g) reboot

I hope this helps someone.

Fred
