18 also the name of the configuration file entry that implements that
19 option. Note that any boolean option can be negated on the command line
20 by preceding the specified option with -no- or -n. example: -no-cas or
21 -nf.
22 Informational Options

196 prevent all transfers in which the client does not request an
197 authenticated and encrypted data channel.
198 This option can also be set in the configuration file as
200 encrypt_data. The default value of this option is FALSE.
201 -si,-secure-ipc
203 Use GSI security on ipc channel.

255 variables $HOME and $USER can be used to create a dynamic path that
256 is unique to each local account. This pathmust be writable by the
257 associated account. The default path is $HOME/.globus/sharing/.
258 This must refer to a path on the filesystem, not a path that is
259 only accessible via a DSI plugin.
260 This option can also be set in the configuration file as
262 sharing_state_dir.
263 -sharing-control

268 This option can also be set in the configuration file as
270 sharing_control. The default value of this option is TRUE.
271 -sharing-rp string

274 normal path restrictions (-rp) when an account is being shared by a
275 sharing-dn login.Follows normal path restriction semantics.
276 This option can also be set in the configuration file as
278 sharing_rp.
279 -sharing-users-allow string
281 Comma separated list of usernames that are allowed to share unless

313 This option can also be set in the configuration file as
315 allow_root. The default value of this option is FALSE.
316 -allow-disabled-login
318 Do not check if a user’s system account is disabled before allowing
319 login.
320 This option can also be set in the configuration file as
322 allow_disabled_login. The default value of this option is FALSE.

332 in daemon mode. Unlimited if not set.
333 This option can also be set in the configuration file as
335 connections_max.
336 -connections-disabled
338 Disable all new connections. For daemon mode, issue a SIGHUP to the
339 server process after changing the config file in order to not
340 affect ongoing connections.
341 This option can also be set in the configuration file as
343 connections_disabled. The default value of this option is FALSE.
344 -offline-msg string

347 offline via the connections_disabled or connections_max = 0
348 options.
349 This option can also be set in the configuration file as

364 default value of this option is TRUE.
365 -use-home-dirs
367 Set the starting directory to the authenticated users home dir.
368 Disabling this is the same as setting -home-dir /.
369 This option can also be set in the configuration file as
371 use_home_dirs. The default value of this option is TRUE.
372 -home-dir string
374 Set a path to override the system defined home/starting directory
375 for authenticated users. The special variable strings $USER and
376 $HOME may be used. The authenticated username will be substituted
377 for $USER, and the user’s real home dir will be substituted for
378 $HOME. Be sure to escape the $ character if using these on the
379 command line.
380 This option can also be set in the configuration file as home_dir.
382 -rp string,-restrict-paths string
384 A comma separated list of full paths that clients may access. Each
385 path may be prefixed by R and/or W, denoting read or write access,
386 otherwise full access is granted. If a given path is a directory,
387 all contents and subdirectories will be given the same access.
388 Order of paths does not matter — the permissions on the longest
389 matching path will apply. The special character ~ will be replaced
390 by the authenticated user’s home directory, or the -home-dir
391 option, if used. Note that if the home directory is not accessible,
392 \~ will be set to /. By default all paths are allowed, and access
393 control is handled by the OS. In a striped or split process
394 configuration, this should be set on both the frontend and data
395 nodes.

398 restrict_paths.
399 -rp-follow-symlinks
401 Do not verify that a symlink points to an allowed path before
402 following. By default, symlinks are followed only when they point
403 to an allowed path. By enabling this option, symlinks will be
404 followed even if they point to a path that is otherwise restricted.
405 This option can also be set in the configuration file as
407 rp_follow_symlinks. The default value of this option is FALSE.
408 -em string,-acl string
410 A comma separated list of ACL or event modules to load.

413 Logging Options
415 -d string,-log-level string

417 INFO, TRANSFER, DUMP, ALL. TRANSFER includes the same statistics
418 that are sent to the separate transfer log when -log-transfer is
419 used. Example: error,warn,info. You may also specify a numeric
420 level of 1-255. The default level is ERROR.
421 This option can also be set in the configuration file as log_level.
423 The default value of this option is ERROR.
424 -log-module string
426 globus_logging module that will be loaded. If not set, the default
427 stdio module will be used, and the logfile options apply. Built in
428 modules are stdio and syslog. Log module options may be set by
429 specifying module:opt1=val1:opt2=val2. Available options for the
430 built in modules are interval and buffer, for buffer flush interval
431 and buffer size, respectively. The default options are a 64k buffer
432 size and a 5 second flush interval. A 0 second flush interval will
433 disable periodic flushing, and the buffer will only flush when it
434 is full. A value of 0 for buffer will disable buffering and all
435 messages will be written immediately. Example: -log-module
436 stdio:buffer=4096:interval=10
437 This option can also be set in the configuration file as
439 log_module.
440 -l string,-logfile string
442 Path of a single file to log all activity to. If neither this
443 option or log_unique is set, logs will be written to stderr unless
444 the execution mode is detached or inetd, in which case logging will
445 be disabled.
446 This option can also be set in the configuration file as
448 log_single.
449 -L string,-logdir string
451 Partial path to which gridftp.(pid).log will be appended to
452 construct the log filename. Example: -L /var/log/gridftp/ will
453 create a separate log ( /var/log/gridftp/gridftp.xxxx.log ) for
454 each process (which is normally each new client session). If
455 neither this option or log_single is set, logs will be written to
456 stderr unless the execution mode is detached or inetd, in which
457 case logging will be disabled.
458 This option can also be set in the configuration file as
460 log_unique.
461 -Z string,-log-transfer string
463 Log netlogger style info for each transfer into this file. You may
464 also use the log-level of TRANSFER to include this info in the
465 standard log.
466 This option can also be set in the configuration file as
468 log_transfer.
469 -log-filemode string
471 File access permissions of log files. Should be an octal number

496 usage_stats_id.
497 Single and Striped Remote Data Node Options
499 -r string,-remote-nodes string
500 Comma separated list of remote node contact strings.
501 This option can also be set in the configuration file as
503 remote_nodes.
504 -hybrid
506 When a server is configured for striped operation with the
507 remote_nodes option, both a frontend and backend process are
508 started even if the client does not request multiple stripes. This
509 option will start backend processes only when striped operation is
510 requested by the client, while servicing non-striped requests with
511 a single frontend process.
512 This option can also be set in the configuration file as hybrid.

532 otherwise the default is 1.
533 This option can also be set in the configuration file as
535 stripe_count.

573 storage systems. See the manpage for sync() for more information.
574 This option can also be set in the configuration file as
576 sync_writes. The default value of this option is FALSE.
577 -perms string
579 Set the default permissions for created files. Should be an octal
580 number such as 0644. The default is 0644. Note: If umask is set it
581 will affect this setting — i.e. if the umask is 0002 and this
582 setting is 0666, the resulting files will be created with
583 permissions of 0664.
584 This option can also be set in the configuration file as perms.

673 GLOBUS_TCP_PORT_RANGE.
674 This option can also be set in the configuration file as
676 port_range.
677 -epsv-ip
679 Adds an IPv6 address to EPSV response. Breaks RFC 2428, but allows
