SFTP-SERVER(8) BSD System Manager's Manual SFTP-SERVER(8)NAMEsftp-server - SFTP server subsystem
SYNOPSISsftp-server [-eh] [-f log_facility] [-l log_level] [-u umask]
DESCRIPTIONsftp-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,
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 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.
