Connecting to a Windows Shared Drive from CentOS using smbclient

What is the quickest way to access a Windows Shared Drive from CentOS ? Use smbclient !

It’s an FTP-like client to access SMB/CIFS resources on a server and its part of the “samba-client” package which is installed by default on CentOS.

[laurent@localhost Downloads]$ rpm -qf /usr/bin/smbclient
samba-client-3.5.10-114.el6.i686

The firewall is pre-configured so you don’t need to change anything to use it:

If you look on the internet, you’ll find lots of posts telling you to use this syntax: smbclient [SHARED_DRIVE_UNC_PATH] -U [username]. But if your target Windows server belongs to a domain, you’ll get an NT_STATUS_LOGON_FAILURE error:

[laurent@localhost Downloads]$ smbclient //10.6.9.206/tmp -U laurent
Enter laurent's password:
session request to 10.6.9.206 failed (Called name not present)
session setup failed: NT_STATUS_LOGON_FAILURE

That’s because the domain name must be provided using the -W option. Also (and I must say that I lost a couple of minutes before of this), the password that you must enter is the one from the domain you want to connect to, not the one from your local Linux account.

[laurent@localhost Downloads]$ smbclient //10.6.9.206/tmp -U laurent -W entropysoft
Enter laurent's password:
Domain=[ENTROPYSOFT] OS=[Windows 7 Professional 7601 Service Pack 1] Server=[Windows 7 Professional 6.1]
 smb: \>

From there, you can navigate in the target system using the “ls” & “cd” commands and upload/download files using the “put” & “get” commands: see the smbclient man pages for more information.

smb: \> ls
