SYNOPSIS

       globus-url-copy [options] SOURCE-URL DESTINATION-URL

DESCRIPTION

       The globus-url-copy program is a command line tool for multi-protocol data movement. It supports gsiftp:// (GridFTP), ftp://, http://, https://, sshftp:// and file:///

       protocol specifiers in the URL.

           Create destination directory if needed.

       -r

           Copy files in subdirectories

       -fast

           Recommended when using GridFTP servers. Use MODE E for all data transfers, including reusing data channels between list and transfer operations.

       -v, -verbose

           Display URLs being transferred

           Debug ftp connections. Prints control channel communication to stderr

       -rst, -restart

           Restart failed ftp operations.

       -rst-retries RETRIES

           The maximum number of times to retry the operation before giving up on the transfer. Use  for infinite. Default is .

       -rst-interval SECONDS

           The interval in seconds to wait after a failure before retrying the transfer. Use  for an exponential backoff. Default is .

           Set the credentials to use for destination ftp connections.

       -af FILENAME, -alias-file FILENAME

           File with mapping of logical host aliases to lists of physical hosts. When used with multiple concurrent connections, each connection uses the next host in the list. Each

           line should either be an alias, noted with the @ symbol, or a hostname[:port]. Currently, only the aliases @source and @destination are valid, and they are used for every

           source or destination URL.

       -sync

           Only transfer files where the destination does not exist or differs from the source. -sync-level controls how to determine if files differ.

           Criteria for determining if files differ when performing a sync transfer. The default sync level is . The available levels are:

           ·   Level  will only transfer if the destination does not exist.

           ·   Level  will transfer if the size of the destination does not match the size of the source.

           ·   Level  will transfer if the time stamp of the destination is older than the time stamp of the source.

           ·   Level  will perform a checksum of the source and destination and transfer if the checksums do not match. The default algorithm used for this checksum is MD5, but

               other algorithms can be specified with the -algo parameter.

       -checksum-alg CHECKSUM-ALGORITHM

           Set the algorithm type to use for all checksum operations during the transfer.

       -verify-checksum

           Perform a checksum on the source and destination after each file transfer and compare the two. If they do not match, fail the transfer. The default algorithm used for this

           checksum is MD5, but other algorithms can be specified with the -checksum-alg parameter.

SYNOPSIS

       globus-gridftp-server OPTIONS

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 is FALSE.

       -hh,-longhelp

           Show more usage information and exit.

           This option can also be set in the configuration file as longhelp. The default value of this option is FALSE.

       -v,-version

           Show version information for the server and exit.

           This option can also be set in the configuration file as version. The default value of this option is FALSE.

       -V,-versions

           Show version information for all loaded globus libraries and exit.

           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 this option is TRUE.

       -S,-detach

           Run as a background daemon detached from any controlling terminals.

           This option can also be set in the configuration file as detach. The default value of this option is FALSE.

       -ssh

           Run over a connected ssh session.

           This option can also be set in the configuration file as ssh. The default value of this option is FALSE.

       -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.

       -chdir

           Change directory when the server starts. This will change directory to the dir specified by the chdir_to option.

           This option can also be set in the configuration file as chdir. The default value of this option is TRUE.

       -chdir-to string

       -threads number

           Enable threaded operation and set the number of threads. The default is , which is non-threaded. When threading is required, a thread count of  or  should be

           sufficient.

           This option can also be set in the configuration file as threads.

       -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. The default value of this option is TRUE.

       -anonymous-names-allowed string

           Comma separated list of names to treat as anonymous users when allowing anonymous access. If not set, the default names of anonymous and ftp will be allowed. Use * to

           allow any username.

       -sharing-dn string

           Allow sharing when using the supplied DN. A client connected with these credentials will be able to access any user for which sharing is enabled.

       -sharing-state-dir string

           Full path to a directory that will contain files used by GridFTP to control sharing access for individual local accounts. The special variables $HOME and $USER can be used

           to create a dynamic path that is unique to each local account. This pathmust be writable by the associated account. The default path is $HOME/.globus/sharing/. This must

           refer to a path on the filesystem, not a path that is only accessible via a DSI plugin.

           This option can also be set in the configuration file as sharing_state_dir.

       -sharing-control

           Allow a local user account to control its own sharing access via special GridFTP client commands. The user account must have filesystem write access to the sharing state

           dir.

           This option can also be set in the configuration file as sharing_control. The default value of this option is TRUE.

       -sharing-rp string

           Sharing specific path restrictions. This completely replaces the normal path restrictions (-rp) when an account is being shared by a sharing-dn login.Follows normal path

       -sharing-groups-allow string

           Comma separated list of groups whose members are allowed to share unless matched in the user or group deny lists. If this list is set, groups that are not included will be

           denied unless matched in the user allow list.

           This option can also be set in the configuration file as sharing_groups_allow.

       -sharing-groups-deny string

           Comma separated list of groups whose members will be denied sharing unless matched in the user allow list.

           buffer size, respectively. The default options are a 64k buffer size and a  second flush interval. A  second flush interval will disable periodic flushing, and the

           buffer will only flush when it is full. A value of  for buffer will disable buffering and all messages will be written immediately. Example: -log-module

           stdio:buffer=:interval=

       -L string,-logdir string
