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_config5
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
.
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
.
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.
