rfuadmin(1M)          (Remote File Sharing Utilities)          rfuadmin(1M)


   NAME
         rfuadmin - Remote File Sharing notification shell script

   SYNOPSIS
         /etc/rfs/rfuadmin message remote_resource [seconds]

   DESCRIPTION
         The rfuadmin administrative shell script responds to unexpected
         Remote File Sharing events, such as broken network connections and
         forced unmounts, picked up by the rfudaemon process.  This command is
         not intended to be run directly from the shell.

         The response to messages received by rfudaemon can be tailored to
         suit the particular system by editing the rfuadmin script.  The
         following paragraphs describe the arguments passed to rfuadmin and
         the responses.

         disconnect remote_resource
                 A link to a remote resource has been cut.  rfudaemon executes
                 rfuadmin, passing it the message disconnect and the name of
                 the disconnected resource. rfuadmin sends this message to all
                 terminals using wall(1):

                 Remote_resource has been disconnected from the system.

                 Then it executes fuser(1M) to kill all processes using the
                 resource, unmounts the resource [umount(1M)] to clean up the
                 kernel, and starts rmount to try to remount the resource.
         fumount remote_resource
                 A remote server machine has forced an unmount of a resource a
                 local machine has mounted.  The processing is similar to
                 processing for a disconnect.
         fuwarn remote_resource seconds
                 This message notifies rfuadmin that a resource is about to be
                 unmounted.  rfudaemon sends this script the fuwarn message,
                 the resource name, and the number of seconds in which the
                 forced unmount will occur.  rfuadmin sends this message to
                 all terminals:

                 Remote_resource is being removed from the system in #
                 seconds.

   BUGS
         The console must be on when Remote File Sharing is running.  If it's
         not, rfuadmin will hang when it tries to write to the console (wall)
         and recovery from disconected resources will not complete.
