Linux to Windows - can list smb shares but cannot connect

Question

This is a really weird one and all the research I've done so far isn't panning out.

I'm trying to connect to a Windows share from CentOS 7.5.1804 to Windows Server 2008 R2 (no snickering and let's stay on topic please) share. This server:

• has not been promoted to a domain controller
• resides on a flat network
• Everyone has read/write to the share (I changed this for troubleshooting)
• the share is named MyShare

When I run this command from Linux:

smbclient -L <IP> -U Administrator

I get this:

    Sharename       Type      Comment
    ---------       ----      -------
    ADMIN$          Disk      Remote Admin
    C$              Disk      Default share
    IPC$            IPC       Remote IPC
    MyShare         Disk      
    Users           Disk      
Reconnecting with SMB1 for workgroup listing.
Connection to <IP> failed (Error NT_STATUS_RESOURCE_NAME_NOT_FOUND)
Failed to connect with SMB1 -- no workgroup available

Weird. It throws an error but still lists all the shares. Googling "NT_STATUS_RESOURCE_NAME_NOT_FOUND" hasn't yielded a lot of info.

Since the share was found, I pressed on with:

mount -v -t cifs //<IP>/MyShare /mnt -o username=Administrator

It returns this:

mount error(2): No such file or directory
Refer to the mount.cifs(8) manual page (e.g. man mount.cifs)

So I read the man page and this can not use mount.cifs: mount error(2): No such file or directory

...and started thinking I need to specy the version or ntlm level.

I tried this:

mount -v -t cifs //<IP>/MyShare /mnt -o username=Administrator, vers=2.0

and

mount -v -t cifs //<IP>/MyShare /mnt -o username=Administrator, sec=ntlmv2

and they both error out because of incorrect syntax... but that's what was supplied as an example on that webpage and in the man page!

Any suggestions how to get the mount command working would be greatly appreciated. Thanks!

Answer 1

There is a syntax error in the mount command, the space after the comma.

mount -v -t cifs //<IP>/MyShare /mnt -o username=Administrator,vers=2.0

should work.

Answer 2

Try to create a new folder:

mkdir /media/MGoBlue93/cifsShare

And mount to it, I think that this issue is related to permissions, and you do not have any to mount to /mnt.

Answer 3

smbclient //10.10.10.x/ --option='client min protocol=NT1'

SRC

Answer 4

Use below command:-

smbclient //IP/MyShare/ -m SMB3
