NAME

       ssh_sftpd - Specifies the channel process to handle an sftp subsystem.

DESCRIPTION

       Specifies a channel process to handle a sftp subsystem.

DATA TYPES

       subsystem_spec() = {subsystem_name(), {channel_callback(), channel_init_args()}}

       subsystem_name() = "sftp"

       channel_callback()  =  atom() - Name of the erlang module implementing the subsystem using
       the ssh_channel behavior see ssh_channel(3erl)

        channel_init_args() = list() - The one given as argument to function subsystem_spec/1.

EXPORTS

       subsystem_spec(Options) -> subsystem_spec()

              Types:

                 Options = [{Option, Value}]

              Should be used together with ssh:daemon/[1,2,3]

              Options are:

                {cwd, String}:
                  Sets the initial current working directory for the server.

                {file_handler, CallbackModule}:
                  Determines which module to call for accessing  the  file  server.  The  default
                  value  is  ssh_sftpd_file  that  uses  the file and filelib API:s to access the
                  standard OTP file server. This option  may  be  used  to  plug  in  other  file
                  servers.

                {max_files, Integer}:
                  The  default value is 0, which means that there is no upper limit. If supplied,
                  the number of filenames returned to the sftp  client  per  READDIR  request  is
                  limited to at most the given value.

                {root, String}:
                  Sets  the  sftp root directory. The user will then not be able to see any files
                  above this root. If for instance the root is set to /tmp the user will see this
                  directory as / and if the user does cd /etc the user will end up in /tmp/etc.

                {sftpd_vsn, integer()}:
                  Sets the sftp version to use, defaults to 5. Version 6 is under development and
                  limited.
