Specifies a channel process to handle an SFTP subsystem.
subsystem_spec(Options) -> Spec
Types:
Options =
[{cwd, string()} |
{file_handler, CbMod | {CbMod, FileState}} |
{max_files, integer()} |
{root, string()} |
{sftpd_vsn, integer()}]
Spec = {Name, {CbMod, Options}}
Name = string()
CbMod = atom()
FileState = term()
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.
