When accessing SMB shared that are password-protected, smbclient works just fine.
But when I'm trying to access shared that have no password protection (public shares), smbclient prints:
tree connect failed: NT_STATUS_ACCESS_DENIED How can I access those shares?
I'm trying to access Windows 7 from my Ubuntu 12.10
Answering quite an old question, I can do this using smbclient like this:
$ smbclient //host/share -U " "%" " Domain=[WORKGROUP] OS=[Windows 2000] Server=[Windows 2000 LAN Manager] smb: \> This is from a fedora 21 host connecting to a solaris clone (omnios), but should be the same to a windows host.
-U|--user=username[%password]. Therefore, this answer users the "single-space" username with a "single-space" password. smbclient //host/share -U guest% worked for me. -U % worked for me if your mount point is /home/myuser/mountpoint and shared folder is named sharefolder. You should try mount -t cifs //<your shareserver name or ip>/sharefolder -o username=guest,password="" /home/myuser/mountpoint
mount error(5): Input/output error. Refer to the mount.cifs(8) manual page (e.g. man mount.cifs) And if I sniff with Wireshark I see I get STATUS_ACCOUNT_RESTRICTION from the server Could you check which security option is given in your smb.conf. By default security = user option will be enabled under Standalone Server option .User level of security asks for username/passwd in windows while if you keep the security = share it wont ask for credentials or can access share without password. This option can also be appended to your local share definitions.
security = user but it was also commented-out. Tries un-commenting it, and changed it to security = share, but I got the same results This is an old question, but I fixed this problem for guest account access by enabling the following policy in Group Policy Management:
Default Domain Policy > Computer Configuration > Policies > Windows Settings > Security Settings > Local Policies > Security Options > Accounts: Guest account status
Even though it is not defined, it is disabled by default and prevents enumeration of the share.
From here:
by default network access is denied to accounts which don't have a password... you can change this option in the group policy Well, appears it's not possible. Microsoft probably thought this is clever..
In my case this syntax was working great on smbclient Version 4.3.11-Ubuntu to copy a file on another linux server using smb share:
smbclient '//server.domain.local/share' -U 'myuser%' -c 'put "/tmp/filen_to_copy.txt" "subfolder\copied_file.txt"' I think it works with Windows server w/o AD.
@bernie had the right idea. The following command works following this syntax:
smbclient -L '//10.10.16.165/' -U '%' OR smbclient '//10.10.16.165/SHARE' -U '%'
