.Sh NAME
.Nm sftp-server
.Nd SFTP server subsystem
.Sh SYNOPSIS
.Nm sftp-server
.Op Fl f Ar log_facility
.Op Fl l Ar log_level
.Sh DESCRIPTION
.Nm
is a program that speaks the server side of SFTP protocol
to stdout and expects client requests from stdin.
.Nm
is not intended to be called directly, but from
.Xr sshd 8
using the
.Cm Subsystem
option.
.Pp
Command-line flags to
.Nm
should be specified in the
.Cm Subsystem
declaration.
See
.Xr sshd_config 5
for more information.
.Pp
Valid options are:
.Bl -tag -width Ds
.It Fl f Ar log_facility
Specifies the facility code that is used when logging messages from
.Nm .
The possible values are: DAEMON, USER, AUTH, LOCAL0, LOCAL1, LOCAL2,
LOCAL3, LOCAL4, LOCAL5, LOCAL6, LOCAL7.
The default is AUTH.
.It Fl l Ar log_level
Specifies which messages will be logged by
.Nm .
The possible values are:
QUIET, FATAL, ERROR, INFO, VERBOSE, DEBUG, DEBUG1, DEBUG2, and DEBUG3.
INFO and VERBOSE log transactions that
.Nm
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.
.El
.Pp
For logging to work,
.Nm
must be able to access
.Pa /dev/log .
Use of
.Nm
in a chroot configuation therefore requires that
.Xr syslogd 8
establish a logging socket inside the chroot directory.
