SMB Shares - Cannot Browse After Update

[fzinken]

@jheldens

can you tell me what the equivalent is of net view command on raspberry pi (osmc) afik it is running a linux flavor and ‘net view’ is a windows command

Well SMB is also a windows protocol But similar like SMB also the surrounding commands have been replicated in linux. So actually there is a net command on linux but that is more for local samba shares.

So please use smbclient -L osxserver

[jheldens]

@fzinken

smbclient -L osxserver

Is it normal that this command is not installed by default on the pi.
I just did a complete reinstall (new image) becuase on my install the command was missing.
But the command is not installed by default . I’ll guss i have to install the commands through apt-get.

But is this normal ?
I used the default osmc installler on mac.

[jheldens]

Used the following command to install smb support (found in some other post)

sudo apt-get update && sudo apt-get install smb-app-osmc will install and configure Samba for you.

@jheldens

But is this normal ?

Yeah sorry, forgot that it only is installed when the Samba server is installed.

[jheldens]

Ok did all that stil no smbclient.

Installed the package smb-app-osmc.
Tried installing package samba --> message alrady installed (guess it comes with the previous).
Went to the osmc app store. It shows the samba server is installed. So all seems to be OK.

Do I need to be in a specific directory for the command to work ?

I am lost?

I am lost?

try sudo apt-get install smbclient

Hoera I got something hope it helps you:

Try adding

client use spnego = no
client ntlmv2 auth = no

to /etc/samba/smb.conf

Then run again. It is definitely the issue about the not supported security level of your OSX server.
Actually wonder if you can upgrade the OSX server.

[jheldens]

@fzinken

client use spnego = no
client ntlmv2 auth = no

Added the 2 lines to the global section. rebooted the machine to ensure the new settings take effect. Re-issued the command.

smbclient -L osxserver
Enter osmc’s password:
protocol negotiation failed: NT_STATUS_NOT_SUPPORTED
osmc@osmc:~$

FYI : extraction of the modified /etc/samba/smb.conf
[global]

If you require a fully custom smb.conf create smb-local.conf instead of editing sm$

configuration will not be overwritten by samba upgrades. You can use smb.conf as a$

copying it to smb-local.conf then removing the config file line below in the new f$

need to add some additional shares see smb-shares.conf below for a simpler way to $

I was able to execute the net view command on the windows laptop. It only show the laptop itself

see dump:

C:\Users\MAENA>net view
Servernaam Opmerking

\LPTCO04
De opdracht is voltooid.

C:\Users\MAENA>

@jheldens

I was able to execute the net view command on the windows laptop.

But you are still able to access the samba share on the OSX Server from the Windows Laptop?
Unfortunately I am not an OSX expert.

[jheldens]

Correct. before issuing the command i started kodi and started a movie. It all worked fine.
Closed kodi and than run the command.

I think I am not the only mac users with the problem see also recent post:

Adding OS X El Capitan folder to Kodi/OSMC via SMB

Hi, I’ve been looking around on a great how to add a folder on a mac via smb, but have had no luck. What have I done: Checked the Kodi wiki http://kodi.wiki/view/SMB/Mac and watched Share Folder via MAC OSX How to - For XBMC on Apple TV 2 - YouTube Question: Do I, or do I not, check my account (in the video the dude selected Bell) and enter a password? (And why?) Second Question: If I do, should I use my account and password when adding the connection in Kodi? → I have tried both When a…

What I am going to do now is use the kodi installer and reinstall an older build (before april) to see if that helps. I’ll keep you posted.

[LinkeLoutje]

Thanks for including me (awesome forum feature btw). I’m curious whether our issues are related.

[jheldens]

Ok some more information:

redid test with release

2016.02.03
2016.04.01

Both not possible to access smb share on mac (shared through the mac server app). This was however possible at the time.

My question when i install these images do I only get the OSMC version from that period and do I also get the supporting files from that period (samba etc…) or do I automatically get the most recent ones ?

Now trying an openelec build…

[jheldens]

Tried stable build openelec 6.0.3 and beta 6.95.3 both unable to connect to smb shares defined on a mac through mac server app.

I guess something is off between osmc (samba linux implementation) and the latest samba implementation on the mac (using osx 10.11.5 and server 5.1.5).

I am hoping some guru can figure this one out. I am lost

If you install the old image, you will get all old files till you update.
So this looks like a server issue

[sam_nazarko]

Seems server related.

OpenELEC uses Samba 3.x, which doesn’t have the Badlock CVE patches which have caused the SMB regressions reported. So OE should work.

[jheldens]

I think you are right upgraded osx also during the period to 10.11.4 and just recently to 10.11.5 and it seems that osx has some issues with its samba implementation (apple has its own implementation of the protocol)

see links:
https://forums.developer.apple.com/thread/44739

https://discussions.apple.com/thread/7565683?start=15&tstart=0

But this exceeds my knowledge level. I keep fiddling around ; and hope that some mac / osmc user with more knowledge can figure this one out.

If i find something I’ll post it here.

Anyway thanks for your support so far

Try going to Add Network Location in the videos Add File Location area, and type your network path.

Like: //COMPUTERNAME

[jheldens]

Done that gives an error saying it cannot connect to the network share.
“Do you still want to add it etc…”
Added it but it is not usable.

Now trying to add the share via the command line but also that is not working the error is persmission denied.

sudo mount -v -t cifs //osxserver/MediaFiles /mnt/MediaFiles -o username=xxxxxx,password=xxxx
mount.cifs kernel mount options: ip=192.168.0.x,unc=\osxserver\MediaFiles,user=xxxx,pass=********
