# SFTP subsystem mode
|
|
|
|
In this mode SFTPGo speaks the server side of SFTP protocol to stdout and expects client requests from stdin.
|
|
You can use SFTPGo as subsystem via the `startsubsys` command.
|
|
This mode is not intended to be called directly, but from sshd using the `Subsystem` option.
|
|
For example adding a line like this one in `/etc/ssh/sshd_config`:
|
|
|
|
```shell
|
|
Subsystem sftp sftpgo startsubsys
|
|
```
|
|
|
|
Command-line flags should be specified in the Subsystem declaration.
|
|
|
|
```shell
|
|
Usage:
|
|
sftpgo startsubsys [flags]
|
|
|
|
Flags:
|
|
-d, --base-home-dir string If the user does not exist specify an alternate
|
|
starting directory. The home directory for a new
|
|
user will be:
|
|
|
|
<base-home-dir>/<username>
|
|
|
|
base-home-dir must be an absolute path.
|
|
-c, --config-dir string Location for SFTPGo config dir. This directory
|
|
should contain the "sftpgo" configuration file
|
|
or the configured config-file and it is used as
|
|
the base for files with a relative path (eg. the
|
|
private keys for the SFTP server, the SQLite
|
|
database if you use SQLite as data provider).
|
|
This flag can be set using SFTPGO_CONFIG_DIR
|
|
env var too. (default ".")
|
|
-f, --config-file string Name for SFTPGo configuration file. It must be
|
|
the name of a file stored in config-dir not the
|
|
absolute path to the configuration file. The
|
|
specified file name must have no extension we
|
|
automatically load JSON, YAML, TOML, HCL and
|
|
Java properties. Therefore if you set "sftpgo"
|
|
then "sftpgo.json", "sftpgo.yaml" and so on
|
|
are searched.
|
|
This flag can be set using SFTPGO_CONFIG_FILE
|
|
env var too. (default "sftpgo")
|
|
-h, --help help for startsubsys
|
|
-j, --log-to-journald Send logs to journald. Only available on Linux.
|
|
Use:
|
|
|
|
$ journalctl -o verbose -f
|
|
|
|
To see full logs.
|
|
If not set, the logs will be sent to the standard
|
|
error
|
|
-v, --log-verbose Enable verbose logs. This flag can be set
|
|
using SFTPGO_LOG_VERBOSE env var too.
|
|
(default true)
|
|
-p, --preserve-home If the user already exists, the existing home
|
|
directory will not be changed
|
|
```
|
|
|
|
In this mode `bolt` and `sqlite` providers are not usable as the same database file cannot be shared among multiple processes, if one of these provider is configured it will be automatically changed to `memory` provider.
|
|
|
|
The username and home directory for the logged in user are determined using [user.Current()](https://golang.org/pkg/os/user/#Current).
|
|
If the user who is logging is not found within the SFTPGo data provider, it is added automatically.
|
|
You can pre-configure the users inside the SFTPGo data provider, this way you can use a different home directory, restrict permissions and such.
