NAME
sftp-server - SFTP server subsystem
SYNOPSIS
sftp-server [-f log_facility] [-l log_level]
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:
-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.
-l log_level
Specifies which messages will be logged by sftp-server. The pos‐
sible values are: SILENT, QUIET, FATAL, ERROR, INFO, VERBOSE,
DEBUG, DEBUG1, DEBUG2, and DEBUG3. INFO and VERBOSE log transac‐
tions 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.
sftp(1), ssh(1), sshd_config(5), sshd(8)
