The globus gridftp server daemon
globus-gridftp-server [-options]
The globus-gridftp-server program is a ftp server with support for GridFTP protocol extensions, including strong authentication, parallel data transfers, and parallel data layouts.
The list below contains the command-line options for the server, and also the name of the configuration file entry that implements that option. Note that any boolean flag can be negated on the command line by preceding the specified option with -no- or -n. Example: -no-fork or -nf.
-h , -help
Show usage information and exit. This option can also be set in the configuration file as help.
-hh , -longhelp
Show more usage information and exit. This option can also be set in the configuration file as longhelp.
-v , -version
Show version information for the server and exit. This option can also be set in the configuration file as version.
-V , -versions
Show version information for all loaded globus libraries and exit. This option can also be set in the configuration file as versions.
-i , -inetd
Run under an inetd service. This option can also be set in the configuration file as inetd.
-s , -daemon
Run as a daemon. All connections will fork off a new process and setuid if allowed. This option can also be set in the configuration file as daemon.
-S , -detach
Run as a background daemon detached from any controlling terminals. This option can also be set in the configuration file as detach.
-ssh
Run over a connected ssh session. This option can also be set in the configuration file as ssh.
-exec string
For statically compiled or non-GLOBUS_LOCATION standard binary locations, specify the full path of the server binary here. Only needed when run in daemon mode. This option can also be set in the configuration file as exec.

-f , -fork
Server will fork for each new connection. Disabling this option is only recommended when debugging. Note that non-forked servers running as \'root\' will only accept a single connection, and then exit. This option can also be set in the configuration file as fork.
-1 , -single
Exit after a single connection. This option can also be set in the configuration file as single.
-chroot-path string
Path to become the new root after authentication. This path must contain a valid certificate structure, /etc/passwd, and /etc/groups. The command globus-gridftp-server-setup-chroot can help create a suitable directory structure. This option can also be set in the configuration file as chroot_path.

If a given path is a directory, all contents and subdirectories will be given the same access. Order of paths does not matter -- the permissions on the longest matching path will apply. The special character \'~\' will be replaced by the authenticated user\'s home directory. Note that if the authenticated user\'s home directory is not accessible, the home directory and starting path will be set to \'/\'. By default all paths are allowed, and access control is handled by the OS. This option can also be set in the configuration file as restrict_paths.

Available options for the built in modules are \'interval\' and \'buffer\', for buffer flush interval and buffer size, respectively. The default options are a 64k buffer size and a 5 second flush interval. A 0 second flush interval will disable periodic flushing, and the buffer will only flush when it is full.

-L string, -logdir string
Partial path to which \'gridftp.(pid).log\' will be appended to construct the log filename. Example: -L /var/log/gridftp/ will create a separate log ( /var/log/gridftp/gridftp.xxxx.log ) for each process (which is normally each new client session). If neither this option or log_single is set, logs will be written to stderr unless the execution mode is detached or inetd, in which case logging will be disabled.

The usage stats sent to a particular receiver may be customized by configuring it with a taglist (host:port!taglist) The taglist is a list of characters that each correspond to a usage stats tag. When this option is unset, stats are reported to usage-stats.globus.org:4810. If you set your own receiver, and wish to continue reporting to the Globus receiver, you will need to add it manually.
