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

NAME
sftp-server -- SFTP server subsystem SYNOPSIS
sftp-server [-ehR] [-d start_directory] [-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: -d start_directory specifies an alternate starting directory for users. The pathname may contain the following tokens that are expanded at runtime: %% is replaced by a literal '%', %h is replaced by the home directory of the user being authenticated, and %u is replaced by the user- name of that user. The default is to use the user's home directory. This option is useful in conjunction with the sshd_config(5) ChrootDirectory option. -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 sftp-server. 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 sftp-server. 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. SEE ALSO

NAME
sftp-server - SFTP server subsystem SYNOPSIS
/usr/lib/ssh/sftp-server [-f log_facility] [-l log_level] DESCRIPTION
sftp-server implements the server side of the SSH File Transfer Protocol as defined in the IETF draft-ietf-secsh-filexfer. sftp-server is a subsystem for sshd(1M) and must not be run directly. Command-line flags to sftp-server should be specified in the Subsys- tem declaration. See sshd_config(4) for more information. To enable the sftp-server subsystem for sshd add the following to /etc/ssh/sshd_config: Subsystem sftp /usr/lib/ssh/sftp-server See sshd_config(4) for a description of the format and contents of that file. There is no relationship between the protocol used by sftp-server and the FTP protocol (RFC 959) provided by in.ftpd. OPTIONS
Valid options are listed below. As stated above, these are to be specified in the Subsystem declation of sshd_config. -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 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 equiva- lent. DEBUG2 and DEBUG3 each specify higher levels of debugging output. The default is ERROR. EXIT STATUS
The following exit values are returned: 0 Successful completion. >0 An error occurred. FILES
