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

NAME

sftp-server - SFTP server subsystem

SYNOPSIS

sftp-server [-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: -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. -l log_level Specifies which messages will be logged by sftp-server. The pos- sible 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. -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 configuation therefore requires that syslogd(8) establish a logging socket inside the chroot directory.
