SFTP-SERVER(8)              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 configuation therefore requires that syslogd(8)
     establish a logging socket inside the chroot directory.
