Android Question SMB (Samba) v2/v3 support ? (i.e is there a library for it ?)

[rcscsuk]

Hi
I'm working on application which has a function to copy files from a Windows share to the android device.

I am using the SMB library v1.1 found in these forums.

In testing in a Windows 7 environment this works fine. i.e. a copying files from a Windows 7 share to the device works. On trying this in the production network the share is on a Windows SBS 2011 server and it does not work. I set credentials OK but I do not get back any results when I query for files.

I also tried the MLFiles/MLSmb library also found in these forums - with similar results (it doesn't work).

I think the problem is that the SBS 2011 server is not running SMB v1 (which the Windows 7 probably is).
I tried to confirm this by installing an app from the play store call 'AndSMB' (a network 'browser' app) this has the option to choose SMB v1 or SMB v2/v3. Choosing v1 I could not browse the Window Server shared - choosing SMB v2/v3 I could.

So - can someone confirm that SMB library v1.1 and MLFiles/MLSmb libraries are SMB v1 compatible only ?

And is there a library available for B4A which supports SMB v2/v3 ?

i only know the smb lib. I was not aware that there is a second one MLsmb too. I do not know any other.

 

[Erel]

The SMB library only supports SMB v1. I think that you should be able to configure your server to support SMB v1 clients.

 

[rcscsuk]

Thanks for the reply Erel.

Unfortunately the reason why more and more people are disabling SMB v1 especially on servers (it's disabled by default on Window Server products now I think) is that is not very secure and recent ransomware/malware attacks have exploited these weaknesses. I cannot ask my client to enable a known insecure protocol.

I guess I'll have to rethink my whole method for this app (Any chance v2 support is on the 'to do' list ?)

As i'm a also windows user .. The new SMB Library V2 or V3 is very valuable for me. But i can't i'm new bie. Hope Erel or someone post the new library for us.
thank you for thread. +1

This is important (critical!) for me as well.

This Thread is old but if someone like @MrKim i want to share my exp. Don't use SMB (even SMB v1) Because sending file from android to windows folder is long time (slow speed even wireless 450 M router) i lost my time and there is no updated SMB Version Library in the forum.(SMB V2/V3). So Finally i switched to ftp and ftp is work like charm. Please find FTP library solution. Let it be SMB Good Luck

@MrKim @zabayin @rcscsuk I work for Visuality Systems. We developed an SMB2/SMB3 library for Java named jNQ:

Good luck

Hi ... Mr.@Tal Widerman i'm not java developer and i don't know how to use with it B4A. Is there already wrapped Library that you mention it ? Thank you

 

[Tal Widerman]

Dear @zabayin, there is actually no need for a wrapper. jNQ library is suitable for Android. There are tens of Android apps using this library today.

 

[DonManfred]

Dear @zabayin, there is actually no need for a wrapper.

Sure it is.jNQ is a java library. But to use them in B4A one need to write a wrapper library to expose the jNQ-functionality to be useable from B4A.

I visited your website but i can´t find any download for jNQ. Where can i download the jar file (or AAR)? Or the source to compile it to jar/aar by myself?

Need to check with Android customers, maybe I can provide an example wrapper for B4A.
The link to receive the library is:

Just fill in your details to evaluate the product.

Good luck

Here is a link to what it takes to make a library usable in B4A. I don't have the skill or the time to do it but if you did I'm sure you could sell it here.

[zabayin]

anyway currently there is no SMB v2/v3 lib in forum and also i don't have wrapping skill drives me to use FTP.

 

[Tal Widerman]

Thank you @MrKim for your kind suggestion.
I have looked at this and although building the wrapper does not seem complicated, our focus is on the SMB development.
Customers can receive a Java (or C) library and build the wrapper themselves or ask us to do it, as a side project.

I will update here in case we will have the wrapper in the future.

Any news on this? Has anyone got a SMBv2 or 3 library?

 

[DonManfred]

Any news on this?

Posting to an old thread is a mistake. You should always create a new thread for any issue you have,

The only SMB Library which can work with SMB 2 is https://www.b4x.com/android/forum/threads/jcifs-ng-smb-client-smb2.104560/
