SFTP-SERVER(8) OpenBSD System Manager's Manual SFTP-SERVER(8)
|
|
|
|
NAME
|
|
sftp-server - SFTP server subsystem
|
|
|
|
SYNOPSIS
|
|
sftp-server [-ehR] [-d start_directory] [-f log_facility] [-l log_level]
|
|
[-u umask]
|
|
|
|
DESCRIPTION
|
|
sftp-server is a program that speaks the server side of SFTP protocol to
|
|
stdout and expects client requests from stdin. sftp-server is not
|
|
intended to be called directly, but from sshd(8) using the Subsystem
|
|
option.
|
|
|
|
Command-line flags to sftp-server should be specified in the Subsystem
|
|
declaration. See sshd_config(5) for more information.
|
|
|
|
Valid options are:
|
|
|
|
-d start_directory
|
|
specifies an alternate starting directory for users. The
|
|
pathname may contain the following tokens that are expanded at
|
|
runtime: %% is replaced by a literal '%', %h is replaced by the
|
|
home directory of the user being authenticated, and %u is
|
|
replaced by the username of that user. The default is to use the
|
|
user's home directory. This option is useful in conjunction with
|
|
the sshd_config(5) ChrootDirectory option.
|
|
|
|
-e Causes sftp-server to print logging information to stderr instead
|
|
of syslog for debugging.
|
|
|
|
-f log_facility
|
|
Specifies the facility code that is used when logging messages
|
|
from sftp-server. The possible values are: DAEMON, USER, AUTH,
|
|
LOCAL0, LOCAL1, LOCAL2, LOCAL3, LOCAL4, LOCAL5, LOCAL6, LOCAL7.
|
|
The default is AUTH.
|
|
|
|
-h Displays sftp-server usage information.
|
|
|
|
-l log_level
|
|
Specifies which messages will be logged by sftp-server. The
|
|
possible values are: QUIET, FATAL, ERROR, INFO, VERBOSE, DEBUG,
|
|
DEBUG1, DEBUG2, and DEBUG3. INFO and VERBOSE log transactions
|
|
that sftp-server performs on behalf of the client. DEBUG and
|
|
DEBUG1 are equivalent. DEBUG2 and DEBUG3 each specify higher
|
|
levels of debugging output. The default is ERROR.
|
|
|
|
-R Places this instance of sftp-server into a read-only mode.
|
|
Attempts to open files for writing, as well as other operations
|
|
that change the state of the filesystem, will be denied.
|
|
|
|
-u umask
|
|
Sets an explicit umask(2) to be applied to newly-created files
|
|
and directories, instead of the user's default mask.
|
|
|
|
For logging to work, sftp-server must be able to access /dev/log. Use of
|
|
sftp-server in a chroot configuration therefore requires that syslogd(8)
|
|
establish a logging socket inside the chroot directory.
