1 SFTP-SERVER(8) OpenBSD System Manager's Manual SFTP-SERVER(8)
4 sftp-server - SFTP server subsystem
7 sftp-server [-f log_facility] [-l log_level]
10 sftp-server is a program that speaks the server side of SFTP protocol to
11 stdout and expects client requests from stdin. sftp-server is not in-
12 tended to be called directly, but from sshd(8) using the Subsystem op-
15 Command-line flags to sftp-server should be specified in the Subsystem
16 declaration. See sshd_config(5) for more information.
21 Specifies the facility code that is used when logging messages
22 from sftp-server. The possible values are: DAEMON, USER, AUTH,
23 LOCAL0, LOCAL1, LOCAL2, LOCAL3, LOCAL4, LOCAL5, LOCAL6, LOCAL7.
27 Specifies which messages will be logged by sftp-server. The pos-
28 sible values are: QUIET, FATAL, ERROR, INFO, VERBOSE, DEBUG, DE-
29 BUG1, DEBUG2, and DEBUG3. INFO and VERBOSE log transactions that
30 sftp-server performs on behalf of the client. DEBUG and DEBUG1
31 are equivalent. DEBUG2 and DEBUG3 each specify higher levels of
32 debugging output. The default is ERROR.
34 For logging to work, sftp-server must be able to access /dev/log. Use of
35 sftp-server in a chroot configuation therefore requires that syslogd(8)
36 establish a logging socket inside the chroot directory.
39 sftp(1), ssh(1), sshd_config(5), sshd(8)
