NAME

rfuadmin - Remote File Sharing notification shell script

SYNOPSIS

/etc/rfs/rfuadmin message remote_resource [seconds]

DESCRIPTION

The rfuadmin administrative shell script responds  to  unex-
pected  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  rfu-
daemon  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 process-
        ing 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  termi-
        nals:

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.
