SFTP-SERVER(8)          OpenBSD 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 in-
     tended to be called directly, but from sshd(8) using the Subsystem op-
     tion.

     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: QUIET, FATAL, ERROR, INFO, VERBOSE, DEBUG, DE-
             BUG1, 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 configuration therefore requires that syslogd(8)
     establish a logging socket inside the chroot directory.
