FTP	Rclone docs for FTP backend

{{< icon "fa fa-file" >}} FTP

FTP is the File Transfer Protocol. Rclone FTP support is provided using the
github.com/jlaffaye/ftp
package.

Limitations of Rclone's FTP backend

Paths are specified as remote:path. If the path does not begin with
a / it is relative to the home directory of the user. An empty path
remote: refers to the user's home directory.

Configuration

To create an FTP configuration named remote, run

rclone config

Rclone config guides you through an interactive setup process. A minimal
rclone FTP remote definition only requires host, username and password.
For an anonymous FTP server, use anonymous as username and your email
address as password.

No remotes found - make a new one

r) Rename remote
c) Copy remote
s) Set configuration password
q) Quit config

To see all directories in the home directory of remote

rclone lsd remote:

Make a new directory

rclone mkdir remote:path/to/directory

List the contents of a directory

rclone ls remote:path/to/directory

Sync /home/local/directory to the remote directory, deleting any
excess files in the directory.

rclone sync -i /home/local/directory remote:directory

Example without a config file

rclone lsf :ftp: --ftp-host=speedtest.tele2.net --ftp-user=anonymous --ftp-pass=`rclone obscure dummy`

Implicit TLS

Rlone FTP supports implicit FTP over TLS servers (FTPS). This has to
be enabled in the FTP backend config for the remote, or with
--ftp-tls. The default FTPS port is 990, not 21 and
can be set with --ftp-port.

Restricted filename characters

In addition to the default restricted characters set
the following characters are also replaced:

File names cannot end with the following characters. Repacement is
limited to the last character in a file name:

Character	Value	Replacement
SP	0x20	␠

Not all FTP servers can have all characters in file names, for example:

FTP Server	Forbidden characters
proftpd	*
pureftpd	\ [ ]

This backend's interactive configuration wizard provides a selection of
sensible encoding settings for major FTP servers: ProFTPd, PureFTPd, VsFTPd.
Just hit a selection number when prompted.

Standard Options

Here are the standard options specific to ftp (FTP Connection).

--ftp-host

FTP host to connect to

• Config: host
• Env Var: RCLONE_FTP_HOST
• Type: string
• Default: ""
• Examples:
  • "ftp.example.com"
    • Connect to ftp.example.com

--ftp-user

FTP username, leave blank for current username, $USER

• Config: user
• Env Var: RCLONE_FTP_USER
• Type: string
• Default: ""

--ftp-port

FTP port, leave blank to use default (21)

• Config: port
• Env Var: RCLONE_FTP_PORT
• Type: string
• Default: ""

--ftp-pass

FTP password

NB Input to this must be obscured - see rclone obscure.

• Config: pass
• Env Var: RCLONE_FTP_PASS
• Type: string
• Default: ""

--ftp-tls

Use Implicit FTPS (FTP over TLS)
When using implicit FTP over TLS the client connects using TLS
right from the start which breaks compatibility with
non-TLS-aware servers. This is usually served over port 990 rather
than port 21. Cannot be used in combination with explicit FTP.

• Config: tls
• Env Var: RCLONE_FTP_TLS
• Type: bool
• Default: false

--ftp-explicit-tls

Use Explicit FTPS (FTP over TLS)
When using explicit FTP over TLS the client explicitly requests
security from the server in order to upgrade a plain text connection
to an encrypted one. Cannot be used in combination with implicit FTP.

• Config: explicit_tls
• Env Var: RCLONE_FTP_EXPLICIT_TLS
• Type: bool
• Default: false

Advanced Options

Here are the advanced options specific to ftp (FTP Connection).

--ftp-concurrency

Maximum number of FTP simultaneous connections, 0 for unlimited

• Config: concurrency
• Env Var: RCLONE_FTP_CONCURRENCY
• Type: int
• Default: 0

--ftp-no-check-certificate

Do not verify the TLS certificate of the server

• Config: no_check_certificate
• Env Var: RCLONE_FTP_NO_CHECK_CERTIFICATE
• Type: bool
• Default: false

--ftp-disable-epsv

Disable using EPSV even if server advertises support

• Config: disable_epsv
• Env Var: RCLONE_FTP_DISABLE_EPSV
• Type: bool
• Default: false

--ftp-disable-mlsd

Disable using MLSD even if server advertises support

• Config: disable_mlsd
• Env Var: RCLONE_FTP_DISABLE_MLSD
• Type: bool
• Default: false

--ftp-writing-mdtm

Use MDTM to set modification time (VsFtpd quirk)

• Config: writing_mdtm
• Env Var: RCLONE_FTP_WRITING_MDTM
• Type: bool
• Default: false

--ftp-idle-timeout

Max time before closing idle connections

If no connections have been returned to the connection pool in the time
given, rclone will empty the connection pool.

Set to 0 to keep connections indefinitely.

• Config: idle_timeout
• Env Var: RCLONE_FTP_IDLE_TIMEOUT
• Type: Duration
• Default: 1m0s

--ftp-close-timeout

Maximum time to wait for a response to close.

• Config: close_timeout
• Env Var: RCLONE_FTP_CLOSE_TIMEOUT
• Type: Duration
• Default: 1m0s

--ftp-encoding

This sets the encoding for the backend.

See: the encoding section in the overview for more info.

• Config: encoding
• Env Var: RCLONE_FTP_ENCODING
• Type: MultiEncoder
• Default: Slash,Del,Ctl,RightSpace,Dot
• Examples:
  • "Asterisk,Ctl,Dot,Slash"
    • ProFTPd can't handle '*' in file names
  • "BackSlash,Ctl,Del,Dot,RightSpace,Slash,SquareBracket"
    • PureFTPd can't handle '[]' or '*' in file names
  • "Ctl,LeftPeriod,Slash"
    • VsFTPd can't handle file names starting with dot

Limitations

FTP servers acting as rclone remotes must support passive mode.
The mode cannot be configured as passive is the only supported one.
Rclone's FTP implementation is not compatible with active mode
as the library it uses doesn't support it.
This will likely never be supported due to security concerns.

Rclone's FTP backend does not support any checksums but can compare
file sizes.

rclone about is not supported by the FTP backend. Backends without
this capability cannot determine free space for an rclone mount or
use policy mfs (most free space) as a member of an rclone union
remote.

See List of backends that do not support rclone about
See rclone about

The implementation of : --dump headers,
--dump bodies, --dump auth for debugging isn't the same as
for rclone HTTP based backends - it has less fine grained control.

--timeout isn't supported (but --contimeout is).

--bind isn't supported.

Rclone's FTP backend could support server-side move but does not
at present.

The ftp_proxy environment variable is not currently supported.

Modified time

File modification time (timestamps) is supported to 1 second resolution
for major FTP servers: ProFTPd, PureFTPd, VsFTPd, and FileZilla FTP server.
The VsFTPd server has non-standard implementation of time related protocol
commands and needs a special configuration setting: writing_mdtm = true.

Support for precise file time with other FTP servers varies depending on what
protocol extensions they advertise. If all the MLSD, MDTM and MFTM
extensions are present, rclone will use them together to provide precise time.
Otherwise the times you see on the FTP server through rclone are those of the
last file upload.

You can use the following command to check whether rclone can use precise time
with your FTP server: rclone backend features your_ftp_remote: (the trailing
colon is important). Look for the number in the line tagged by Precision
designating the remote time precision expressed as nanoseconds. A value of
1000000000 means that file time precision of 1 second is available.
A value of 3153600000000000000 (or another large number) means "unsupported".
