15 Command-line flags to sftp-server should be specified in the Subsystem
16 declaration. See sshd_config(5) for more information.
17
18 Valid options are:
19
20 -e Causes sftp-server to print logging information to stderr instead
21 of syslog for debugging.
22
23 -f log_facility
24 Specifies the facility code that is used when logging messages
25 from sftp-server. The possible values are: DAEMON, USER, AUTH,
26 LOCAL0, LOCAL1, LOCAL2, LOCAL3, LOCAL4, LOCAL5, LOCAL6, LOCAL7.
27 The default is AUTH.
28
29 -h Displays sftp-server usage information.

32 Specifies which messages will be logged by sftp-server. The pos-
33 sible values are: QUIET, FATAL, ERROR, INFO, VERBOSE, DEBUG, DE-
34 BUG1, DEBUG2, and DEBUG3. INFO and VERBOSE log transactions that
35 sftp-server performs on behalf of the client. DEBUG and DEBUG1
36 are equivalent. DEBUG2 and DEBUG3 each specify higher levels of
37 debugging output. The default is ERROR.

43 -u umask
44 Sets an explicit umask(2) to be applied to newly-created files
45 and directories, instead of the user's default mask.
46
47 For logging to work, sftp-server must be able to access /dev/log. Use of
48 sftp-server in a chroot configuration therefore requires that syslogd(8)
49 establish a logging socket inside the chroot directory.
