![]() ![]() ![]() Port 137/udp is used for LAN hostname resolution (NBNS) and port 138/udp is used for nearby computer discovery ('Computer Browser' service) – both are completely optional for SMB, and in fact both are NetBIOS-based services which most Windows 10 clients have disabled along with disabling SMBv1. (Unless your client is running Windows 95/98, which needs 139/tcp.) I have set the necessary port access in UFW namely 137/udp, 138/udp, 139/tcp, and 445/tcp. (The Samba username always needs to match your Linux username in order for file permissions to work correctly, but the passwords can be different.) This means that you must set a "Samba password" for your Linux user account before you can connect – use smbpasswd to do this on the Linux server: sudo smbpasswd -a jonathan The only difference is that the passwords are stored separately – Samba needs to store a NTLM-compatible password hash, as it cannot use the standard Linux hashed passwords. So I believe that it wanted a password to connect to the Linux machineīy default, Samba indeed uses the same system accounts as Linux itself does. However, you can share folders and files with Use. (Meanwhile Windows NT/2000/XP series never had per-share passwords in the first place, they were account-based the whole time.)Īll SMB security is now account-based (just like in SSH and other protocols) – you provide a username and password to log in to the SMB server, and then access to shares is granted depending on your user account. To display the Security tab in Windows XP, open Folder Options deselect Use simple file sharing. This security model was used in the Windows 98 era, but was completely removed from Samba in 2012. 12.4.1.2 Windows 200x / XP On MS Windows NT4 / 200x / XP system access control lists on the share itself are set using native tools, usually from File. ![]() On the Sharing tab of the properties window, click the Advanced Sharing button. When users access a Samba server, they connect to a service named for one of. Each section of this configuration file defines a service. Samba does not actually support per-share passwords. Right-click the folder you want to share over the network, and then click Properties. To create a new share location, add a section to the /etc/samba/smb.conf configuration file with these two definitions: sambashare path /sambashare read only No. Check the smb signing settings on the client.I had configured the share to not use a password Reg add HKLM\SYSTEM\CurrentControlSet\Services\LanmanWorkstation\Parameters /v AllowInsecureGuestAuth /d 1 /f /t REG_DWORD Two workarouds which brings back to old behaviour. In the samba log you find some strange errors like “smbd_change_to_root_user”, NT_STATUS_CONNECTION_RESET…. Windows Guest Account Reset TCP Connection Windows resets the tcp session after the smb2 Sessions Setup Response of Samba: Net use \\yourSambaServer\yourInsecureShare /user:"" "" Microsoft has limited the Guest Account in Windows 10 and connections with null sessions (User and Password are null) are prevented: Connect to a SMB Share In the Server Address field, enter smb:// to define the network protocol for SMB, and then enter either the IP address or the hostname. This doesn't access the samba share directly, but it works. The specified server cannot perform the requested operation. Select Tools -> Map Network Drive and select from the VirtualBox Shared Folders section. Since some later Versions of Windows 10 it is no longer possible to access Samba Public shares with Guest access as Windows User SYSTEM(i.e. ![]()
