NAME

       gfkey - management of Gfarm session keys

SYNOPSIS

       gfkey [options]

DESCRIPTION

       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.

OPTIONS

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

       -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.
