NAME

       gfsched - schedule and display available file system nodes

SYNOPSIS

       gfsched -f gfarm-URL [ -D domain-name ] [ -n number ] [ -LMclw ]

       gfsched [ -P gfarm-URL ] [ -D domain-name ] [ -n number ] [ -LMlw ]

DESCRIPTION

       The gfsched command with the -f gfarm-URL option displays available file system nodes which have a file replica of the specified gfarm-URL.

       When  the -f gfarm-URL option is not specified, the gfsched command just displays available file system nodes.  In this case, you can spec-
       ify a metadata server by the -P gfarm-URL option, if necessary.

OPTIONS

       -D domain-name
	      Limits file system node by specifying a domain name or a hostname.

       -c     Displays scheduling information for a file creation, if the file specified by -f doesn't exist.

	      Currently, this option creates the specified file.  But please note that this behavior may be changed in future.

       -L     Suppresses authentication check.	Without this option, the scheduler checks whether the user will be successfully authenticated with
	      the  hosts or not.  This option omits the check to make scheduling faster, but that creates a risk that hosts which fail authentica-
	      tion with the user may be scheduled.

       -M     Suppresses client-side scheduling and only performs metadata-server-side scheduling.  This option makes scheduling faster, but  also
	      creates a risk that hosts which is network-unreachable or fails authentication with the user may be scheduled.

       -P gfarm-URL
	      Specifies  a gfarm-URL or a pathname to identify a metadata server which is used for the scheduling.  This option conflicts with the
	      -f option.

       -f gfarm-URL
	      The gfsched command schedules file system nodes which have a replica of a file specified by this option.	This option conflicts with
	      the -P option.

       -l     Long format.  This option displays port numbers as well as hostnames.  Note that the display format of this option may be changed in
	      future.

       -n number
	      Displays specified number of file system nodes at most.  If this option is not specified, it displays all available nodes.

       -w     Schedules with write-mode.  When this option is specified, file system nodes which don't have enough free space won't be displayed.

	      When both this option and the -f are specified, and if the file is already opened  by  an  existing  process  with  write-mode,  the
	      gfsched command only displays one file system node which is assigned for writing to the file.

       -?     Displays a list of command options.

EXAMPLES

       The following is an example to inquire file system nodes that the metadata server thinks they are currently working.

       $ gfsched -M

NAME

       CURLOPT_USERPWD - user name and password to use in authentication

SYNOPSIS

       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_USERPWD, char *userpwd);

DESCRIPTION

       Pass  a	char  *  as  parameter,  pointing  to  a  zero	terminated  login details string for the connection. The format of which is: [user
       name]:[password].

       When using Kerberos V5 authentication with a Windows based server, you should specify the user name part with the domain name in order  for
       the server to successfully obtain a Kerberos Ticket. If you don't then the initial part of the authentication handshake may fail.

       When  using  NTLM,  the	user  name  can be specified simply as the user name without the domain name should the server be part of a single
       domain and forest.

       To specify the domain name use either Down-Level Logon Name or UPN (User Principal Name) formats. For example, EXAMPLEuser and	user@exam-
       ple.com respectively.

       Some HTTP servers (on Windows) support inclusion of the domain for Basic authentication as well.

       When  using  HTTP and CURLOPT_FOLLOWLOCATION(3), libcurl might perform several requests to possibly different hosts. libcurl will only send
       this user and password information to hosts using the initial host name (unless CURLOPT_UNRESTRICTED_AUTH(3) is set), so if libcurl follows
       locations to other hosts it will not send the user and password to those. This is enforced to prevent accidental information leakage.

       Use  CURLOPT_HTTPAUTH(3)  to specify the authentication method for HTTP based connections or CURLOPT_LOGIN_OPTIONS(3) to control IMAP, POP3
       and SMTP options.

       The user and password strings are not URL decoded, so there's no way to send in a user name containing a colon using this option. Use  CUR-
       LOPT_USERNAME(3) for that, or include it in the URL.

       The application does not have to keep the string around after setting this option.
