       gfkey - management of Gfarm session keys


       gfkey [ options ]


       gfkey  manages  the  session key file, $HOME/.gfarm_shared_key, that is
       used for user authentication by  a  shared  secret  key  in  a  trusted
       environment when connecting to gfsd and/or gfmd.

       When  the  home  directory  is shared among filesystem nodes, it is not
       necessary to use this command.  If not, it is necessary to distribute a
       session key  created with the -c or -f option to every filesystem node,
       in advance.


       -c     Creates a new session key when there is no  valid  session  key.
              If   a  valid  session  key  already  exists,  no  operation  is

       -f     Forces the creation of a  new  session  key,  even  if  a  valid
              session key already exists.

       -p period
              Specifies  the  term of validity in seconds.  This option has to
              be used with the -c or -f option.

       -l     Displays the current key.

       -e     Displays the expiration date of the current key.

       -L message-priority-level
              Specifies a level of the log priority.  The  log  messages  that
              have higher or the same priority than the specified priority are
              displayed to the standard error.  The default priority is  info.
              Refer to the log_level directive described in the manual page of
              gfarm2.conf(5) for the priority level which can be specified  by
              this option.

       -?     Displays a list of command options.
