# {{< icon "fa fa-server" >}} SMB
|
|
|
|
SMB is [a communication protocol to share files over network](https://en.wikipedia.org/wiki/Server_Message_Block).
|
|
|
|
This relies on [go-smb2 library](https://github.com/hirochachacha/go-smb2/) for communication with SMB protocol.
|
|
|
|
Paths are specified as `remote:sharename` (or `remote:` for the `lsd`
|
|
command.) You may put subdirectories in too, e.g. `remote:item/path/to/dir`.
|
|
|
|
## Notes
|
|
|
|
The first path segment must be the name of the share, which you entered when you started to share on Windows. On smbd, it's the section title in `smb.conf` (usually in `/etc/samba/`) file.
|
|
You can find shares by querying the root if you're unsure (e.g. `rclone lsd remote:`).
|
|
|
|
You can't access to the shared printers from rclone, obviously.
|
|
|
|
You can't use Anonymous access for logging in. You have to use the `guest` user with an empty password instead.
|
|
The rclone client tries to avoid 8.3 names when uploading files by encoding trailing spaces and periods.
|
|
Alternatively, [the local backend](/local/#paths-on-windows) on Windows can access SMB servers using UNC paths, by `\\server\share`. This doesn't apply to non-Windows OSes, such as Linux and macOS.
|
|
|
|
## Configuration
|
|
|
|
Here is an example of making a SMB configuration.
|
|
|
|
First run
|
|
|
|
rclone config
|
|
|
|
This will guide you through an interactive setup process.
|
|
|
|
```
|
|
No remotes found, make a new one?
|
|
n) New remote
|
|
s) Set configuration password
|
|
q) Quit config
|
|
n/s/q> n
|
|
name> remote
|
|
Option Storage.
|
|
Type of storage to configure.
|
|
Choose a number from below, or type in your own value.
|
|
XX / SMB / CIFS
|
|
\ (smb)
|
|
Storage> smb
|
|
|
|
Option host.
|
|
Samba hostname to connect to.
|
|
E.g. "example.com".
|
|
Enter a value.
|
|
host> localhost
|
|
|
|
Option user.
|
|
Samba username.
|
|
Enter a string value. Press Enter for the default (lesmi).
|
|
user> guest
|
|
|
|
Option port.
|
|
Samba port number.
|
|
Enter a signed integer. Press Enter for the default (445).
|
|
port>
|
|
|
|
Option pass.
|
|
Samba password.
|
|
Choose an alternative below. Press Enter for the default (n).
|
|
y) Yes, type in my own password
|
|
g) Generate random password
|
|
n) No, leave this optional password blank (default)
|
|
y/g/n> g
|
|
Password strength in bits.
|
|
64 is just about memorable
|
|
128 is secure
|
|
1024 is the maximum
|
|
Bits> 64
|
|
Your password is: XXXX
|
|
Use this password? Please note that an obscured version of this
|
|
password (and not the password itself) will be stored under your
|
|
configuration file, so keep this generated password in a safe place.
|
|
y) Yes (default)
|
|
n) No
|
|
y/n> y
|
|
|
|
Option domain.
|
|
Domain name for NTLM authentication.

|
Enter a string value. Press Enter for the default (WORKGROUP).
|
|

|
|
y) Yes this is OK (default)
