Use: "sftp remote:path",
|
|
Short: `Serve the remote over SFTP.`,
|
|
Long: `rclone serve sftp implements an SFTP server to serve the remote
|
|
over SFTP. This can be used with an SFTP client or you can make a
|
|
remote of type sftp to use with it.
|
|
|
|
You can use the filter flags (eg --include, --exclude) to control what
|
|
is served.
|
|
|
|
The server will log errors. Use -v to see access logs.
|
|
|
|
--bwlimit will be respected for file transfers. Use --stats to
|
|
control the stats printing.
|
|
|
|
You must provide some means of authentication, either with --user/--pass,
|
|
an authorized keys file (specify location with --authorized-keys - the
|
|
default is the same as ssh), an --auth-proxy, or set the --no-auth flag for no
|
|
authentication when logging in.
|
|
|
|
Note that this also implements a small number of shell commands so
|
|
that it can provide md5sum/sha1sum/df information for the rclone sftp
|
|
backend. This means that is can support SHA1SUMs, MD5SUMs and the
|
|
about command when paired with the rclone sftp backend.
|
|
|
|
If you don't supply a --key then rclone will generate one and cache it
|
|
for later use.
|
|
|
|
By default the server binds to localhost:2022 - if you want it to be
|
|
reachable externally then supply "--addr :2022" for example.
|
|
|
|
Note that the default of "--vfs-cache-mode off" is fine for the rclone
|
|
sftp backend, but it may not be with other SFTP clients.
