SMB

SMB is a communication protocol to share files over network.

This relies on go-smb2 library 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 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

  1. rclone config

This will guide you through an interactive setup process.

  1. No remotes found, make a new one?
  2. n) New remote
  3. s) Set configuration password
  4. q) Quit config
  5. n/s/q> n
  6. name> remote
  7. Option Storage.
  8. Type of storage to configure.
  9. Choose a number from below, or type in your own value.
  10. XX / SMB / CIFS
  11.    \ (smb)
  12. Storage> smb
  14. Option host.
  15. Samba hostname to connect to.
  16. E.g. "example.com".
  17. Enter a value.
  18. host> localhost
  20. Option user.
  21. Samba username.
  22. Enter a string value. Press Enter for the default (lesmi).
  23. user> guest
  25. Option port.
  26. Samba port number.
  27. Enter a signed integer. Press Enter for the default (445).
  28. port> 
  30. Option pass.
  31. Samba password.
  32. Choose an alternative below. Press Enter for the default (n).
  33. y) Yes, type in my own password
  34. g) Generate random password
  35. n) No, leave this optional password blank (default)
  36. y/g/n> g
  37. Password strength in bits.
  38. 64 is just about memorable
  39. 128 is secure
  40. 1024 is the maximum
  41. Bits> 64
  42. Your password is: XXXX
  43. Use this password? Please note that an obscured version of this 
  44. password (and not the password itself) will be stored under your 
  45. configuration file, so keep this generated password in a safe place.
  46. y) Yes (default)
  47. n) No
  48. y/n> y
  50. Option domain.
  51. Domain name for NTLM authentication.
  52. Enter a string value. Press Enter for the default (WORKGROUP).
  53. domain> 
  55. Edit advanced config?
  56. y) Yes
  57. n) No (default)
  58. y/n> n
  60. Configuration complete.
  61. Options:
  62. - type: samba
  63. - host: localhost
  64. - user: guest
  65. - pass: *** ENCRYPTED ***
  66. Keep this "remote" remote?
  67. y) Yes this is OK (default)
  68. e) Edit this remote
  69. d) Delete this remote
  70. y/e/d> d

Standard options

Here are the Standard options specific to smb (SMB / CIFS).

--smb-host

SMB server hostname to connect to.

E.g. “example.com”.

Properties:

  • Config: host
  • Env Var: RCLONE_SMB_HOST
  • Type: string
  • Required: true

--smb-user

SMB username.

Properties:

  • Config: user
  • Env Var: RCLONE_SMB_USER
  • Type: string
  • Default: “$USER”

--smb-port

SMB port number.

Properties:

  • Config: port
  • Env Var: RCLONE_SMB_PORT
