DESCRIPTION
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.
OPTIONS
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 option can be
negated on the command line by preceding the specified option with -no- or -n. example:
-no-cas or -nf.
Informational Options
-h,-help
Show usage information and exit.
This option can also be set in the configuration file as help. The default value of

This option can also be set in the configuration file as versions. The default value
of this option is FALSE.
Modes of Operation
-i,-inetd
Run under an inetd service.
This option can also be set in the configuration file as inetd. The default value of
this option is FALSE.
-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. The default value of

substituted for $HOME. Be sure to escape the $ character if using these on the command
line.
This option can also be set in the configuration file as home_dir.
-rp string,-restrict-paths string
A comma separated list of full paths that clients may access. Each path may be
prefixed by R and/or W, denoting read or write access, otherwise full access is
granted. 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, or the -home-dir option, if used. Note that if
the home directory is not accessible, \~ will be set to /. By default all paths are

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. A value of 0 for buffer will disable buffering and
all messages will be written immediately. Example: -log-module
stdio:buffer=4096:interval=10
