Hello

I've got an windows 2012 r2 as a file server,  it worked fine with windows client but not with lunix-based client

I first discovered this problem on an Android phone:http://social.technet.microsoft.com/Forums/en-US/b3a8a7f9-f4b7-4b9f-b586-2ec87fc14d71/cant-access-shared-folders-on-win-2012-r2-with-android-phone?forum=winserverPN

then I did some test on a newly installed lunix OS on a VM today, I found that my server do not response SMB Negotiate Protocol Request from my phone or the testing OS at all.

when I try smbclient -L ServerIP, I get

read_socket_with_timeout: timeout read. read error = Connection reset by peer.
Receiving SMB: Server stopped responding
protocol negotiation failed

the wireshark capture are like this:

35 22.704658 192.168.1.20 192.168.1.10 SMB 260 Negotiate Protocol Request

I don'tknow what's causing this problem ,is there anyone could help me?

Hi,

If you access files stored on Windows Server 2012 R2 from other non-Windows client computers, you need to use NFS protocol.

Using the NFS protocol, you can transfer files between computers running Windows and other non-Windows operating systems, such as Linux or UNIX.

In Windows Server 2012, NFS includes the components, Server for NFS and Client for NFS. Server for NFS enables a computer running Windows Server 2012 to act as a NFS file server for other non-Windows client computers. Client for NFS enables a Windows-based computer that is running Windows Server 2012 to access files that are stored on a non-Windows NFS server.

For more detailed information, please refer to the articles below:

Hi,

thanks for reply.

Im aware of the NFS sharing function on Windows 2012, but its not an option to me as long as it does not support UTF-8 or other unicode charasets( I have lots of non-English name files to share).

Besides, my android devices does not support NFS sharing , so any other solutions?

Hi,

UTF-8 is supported in Win2012, it is built into NFS 4.1 protocol. NFS v2 and v3 support only ASCII strings.
You need to enable NFSv4.1 on client systems. If client systems does not support NFS v4, you may use 3rd party NFS servers.

For more detailed information, please refer to the thread below:

Unfortunately, my lunix client does not support nfsv4, maybe Ill try a 3rd party solution

Thanks anyway

Hello,

Did you find any solution for this problem. I have the same one. On two out of three Domain Controllers, we can#t join the Domain with Linux Clients with teh same wireshark Trace.

Thanks
