DESCRIPTION

       Specifies a channel process to handle an SFTP subsystem.

EXPORTS

       subsystem_spec(Options) -> Spec

              Types:

                 Options =
                     [{cwd, string()} |
                      {file_handler, CallbackModule :: string()} |
                      {max_files, integer()} |
                      {root, string()} |
                      {sftpd_vsn, integer()}]
                 Spec = {Name, {CbMod, Options}}
                 Name = string()
                 CbMod = atom()

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

              The  Name  is  "sftp"  and  CbMod is the name of the Erlang module implementing the
              subsystem using the ssh_server_channel (replaces ssh_daemon_channel) behaviour.

              Options:

                cwd:
                  Sets the initial current working directory for the server.

                file_handler:
                  Determines which module to call for accessing  the  file  server.  The  default
                  value  is  ssh_sftpd_file,  which  uses the file and filelib APIs to access the
                  standard OTP file server. This option  can  be  used  to  plug  in  other  file
                  servers.

                max_files:
                  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:
                  Sets  the  SFTP  root  directory. Then the user cannot see any files above this
                  root. If, for example, the root directory is set to /tmp, then  the  user  sees
                  this  directory  as  /.  If  the  user  then  writes cd /etc, the user moves to
                  /tmp/etc.

                sftpd_vsn:
                  Sets the SFTP version to use. Defaults to 5. Version 6 is under development and
                  limited.
