SFTP-SERVER(8)                           BSD System Manager's Manual                          SFTP-SERVER(8)

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 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.

     For logging to work, sftp-server must be able to access /dev/log.  Use of sftp-server in a chroot con-figuation configuation
     figuation therefore requires that syslogd(8) establish a logging socket inside the chroot directory.
