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


     sftp-server - SFTP server subsystem


     sftp-server [-eh] [-f log_facility] [-l log_level] [-u umask]


     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 intend-
     ed 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:

     -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,
             The default is AUTH.

     -h      Displays sftp-server usage information.

     -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.

     -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.

     sftp-server first appeared in OpenBSD 2.8.
