rclone rcd

Run rclone listening to remote control commands only.

Synopsis

This runs rclone so that it only listens to remote control commands.

This is useful if you are controlling rclone via the rc API.

If you pass in a path to a directory, rclone will serve that directory for GET requests on the URL passed in. It will also open the URL in the browser when rclone is run.

See the rc documentation for more info on the rc flags.

Server options

Use --rc-addr to specify which IP address and port the server should listen on, eg --rc-addr 1.2.3.4:8000 or --rc-addr :8080 to listen to all IPs. By default it only listens on localhost. You can use port :0 to let the OS choose an available port.

If you set --rc-addr to listen on a public or LAN accessible IP address then using Authentication is advised - see the next section for info.

You can use a unix socket by setting the url to unix:///path/to/socket or just by using an absolute path name. Note that unix sockets bypass the authentication - this is expected to be done with file system permissions.

--rc-addr may be repeated to listen on multiple IPs/ports/sockets.

--rc-server-read-timeout and --rc-server-write-timeout can be used to control the timeouts on the server. Note that this is the total time for a transfer.

--rc-max-header-bytes controls the maximum number of bytes the server will accept in the HTTP header.

--rc-baseurl controls the URL prefix that rclone serves from. By default rclone will serve from the root. If you used --rc-baseurl "/rclone" then rclone would serve from a URL starting with "/rclone/". This is useful if you wish to proxy rclone serve. Rclone automatically inserts leading and trailing "/" on --rc-baseurl, so --rc-baseurl "rclone", --rc-baseurl "/rclone" and --rc-baseurl "/rclone/" are all treated identically.

TLS (SSL)

By default this will serve over http. If you want you can serve over https. You will need to supply the --rc-cert and --rc-key flags. If you wish to do client side certificate validation then you will need to supply --rc-client-ca also.

--rc-cert should be a either a PEM encoded certificate or a concatenation of that with the CA certificate. --krc-ey should be the PEM encoded private key and --rc-client-ca should be the PEM encoded client certificate authority certificate.

--rc-min-tls-version is minimum TLS version that is acceptable. Valid values are "tls1.0", "tls1.1", "tls1.2" and "tls1.3" (default "tls1.0").

Template

--rc-template allows a user to specify a custom markup template for HTTP and WebDAV serve functions. The server exports the following markup to be used within the template to server pages:

Parameter Description
.Name The full path of a file/directory.
.Title Directory listing of .Name
.Sort The current sort used. This is changeable via ?sort= parameter
Sort Options: namedirfirst,name,size,time (default namedirfirst)
.Order The current ordering used. This is changeable via ?order= parameter
Order Options: asc,desc (default asc)
.Query Currently unused.
.Breadcrumb Allows for creating a relative navigation
-- .Link The relative to the root link of the Text.
-- .Text The Name of the directory.
.Entries Information about a specific file/directory.
-- .URL The 'url' of an entry.
-- .Leaf Currently same as 'URL' but intended to be 'just' the name.
-- .IsDir Boolean for if an entry is a directory or not.
-- .Size Size in Bytes of the entry.
-- .ModTime The UTC timestamp of an entry.

The server also makes the following functions available so that they can be used within the template. These functions help extend the options for dynamic rendering of HTML. They can be used to render HTML based on specific conditions.

Function Description
afterEpoch Returns the time since the epoch for the given time.
contains Checks whether a given substring is present or not in a given string.
hasPrefix Checks whether the given string begins with the specified prefix.
hasSuffix Checks whether the given string end with the specified suffix.

Authentication

By default this will serve files without needing a login.

You can either use an htpasswd file which can take lots of users, or set a single username and password with the --rc-user and --rc-pass flags.

If no static users are configured by either of the above methods, and client certificates are required by the --client-ca flag passed to the server, the client certificate common name will be considered as the username.

Use --rc-htpasswd /path/to/htpasswd to provide an htpasswd file. This is in standard apache format and supports MD5, SHA1 and BCrypt for basic authentication. Bcrypt is recommended.

To create an htpasswd file:

touch htpasswd
htpasswd -B htpasswd user
htpasswd -B htpasswd anotherUser

The password file can be updated while rclone is running.

Use --rc-realm to set the authentication realm.

Use --rc-salt to change the password hashing salt from the default.
