SFTP-SERVER(8) BSD System Manager’s Manual SFTP-SERVER(8)
NAME
sftp-server — SFTP server subsystem
SYNOPSIS
sftp-server [−ehR] [−f log_facility] [−l log_level] [−u umask]
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:
−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, LOCAL0, LOCAL1, LOCAL2, LOCAL3, LOCAL4, LOCAL5, LOCAL6, LOCAL7. The default is AUTH.
−h
Displays sftp-server usage information.
−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.
−R
Places this instance of sftp-server into a read-only mode. Attempts to open files for writing, as well as other operations that change the state of the filesystem, will be denied.
−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.
