connecting to windows server with SMB2

[Ashish Sangwan]

I am using kernel version 3.8.13 and windows 7.

The below command works successfully:
Linux#> mount -t cifs //107.109.224.147/sharefolder /mnt -o user=a.sangwan -o pass=xxxx -o vers=1.0 -o sec=ntlm

Other than 1.0, all are fail:
Linux#> mount -t cifs //107.109.224.147/sharefolder /mnt -o user=a.sangwan -o pass=xxxx -o vers=2.0 -o sec=ntlm
[ 0][ 64.276000] Status code returned 0xc000006d STATUS_LOGON_FAILURE
[ 0][ 64.284000] CIFS VFS: Send error in SessSetup = -13

Tried with sec=ntlmv2/none/la

Help please!!

Did you tries without "sec=" option at all?

If yes, you should set "echo 1 > /proc/fs/cifs/cifsFYI', try to mount
and collect dmesg output and send it to the list.

I am wondering why SMB1.0 is success as I don't provide domain in that cas too.
Anyway, I will try suggesstion.

Additionally, I am able to connect to samba server (v 4.0.2) from the same machine
without giving any -o sec -o domain option and it is success for all 2.0, 2.1 and 3.0 versions.

Did you tries without "sec=" option at all?

Yes, without sec=ntlm option, I am not able to mount even with vers=1.0

If yes, you should set "echo 1 > /proc/fs/cifs/cifsFYI', try to mount
and collect dmesg output and send it to the list.

In other mail Benjamin has suggessted to additionally provide -o "domain="
I am wondering why SMB1.0 is success as I don't provide domain in that cas too.
Anyway, I will try suggesstion.
Additionally, I am able to connect to samba server (v 4.0.2) from the same machine
without giving any -o sec -o domain option and it is success for all 2.0, 2.1 and 3.0 versions.

Sorry for being unclear, I meant dmesg output of unsuccessful mount
with vers=2.0.

Hello,
Linux#> mount -t cifs //107.109.224.147/sharefolder /mnt -o user=a.sangwan -o pass=xxxx -o vers=2.0 -o sec=ntlm -o domain=DOMAINNAME

Tried, does'nt help :(
Exactly same error code: STATUS_LOGON_FAILURE

Regards,

In order to sec=ntlmv2 succeed, you will need this patch on the Windows 7 box.
http://support.microsoft.com/kb/957441/en-us

For smb2 (vers=2.0), sec=ntlmssp (which is the default) should succeed against
a Windows 7 box.

Would it be possible to attach a wireshark trace of the exchange?

True, I tried without -o sec option and it uses ntlmssp.

sure, below is the packet capture without any -o sec option:

In order to sec=ntlmv2 succeed, you will need this patch on the Windows 7 box.
http://support.microsoft.com/kb/957441/en-us
For smb2 (vers=2.0), sec=ntlmssp (which is the default) should succeed against
a Windows 7 box.
Would it be possible to attach a wireshark trace of the exchange?

Can you check the value of the registry setting on the server?

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\LSA\LMCompatibilityLevel

Can you change it to 3 (or higher upto 5), I think then ntlmv2 will
start working.
