CFSD(8)							  CFSD(8)

NAME
       cfsd - cryptographic file system daemon

SYNOPSIS
       cfsd

DESCRIPTION
       cfsd  is	 the user-level daemon for the Cryptographic File
       System (CFS).  It is essentially an RPC server for the NFS
       protocol	 augmented  with the CFS_ADMIN protocol.  It lis-
       tens on the CFS port (ordinarily port 3049) on the  local-
       host interface.

       The  main  function of cfsd is to manage the keys for cur-
       rently attached encrypted directories, presenting them  in
       clear form under the CFS mount point (typically "/crypt").

       cfsd should  ordinarily	be  invoked  at	 boot  time  from
       /etc/rc (or /etc/rc.local).  The rc file should also start
       mountd(8) daemon with least one file  system  exported  to
       localhost; note that cfsd itself does not handle the mount
       protocol.  Once a mountd is running, the mount(8)  command
       should  be  invoked to mount the exported file system from
       the localhost interface with port=3049.

EXAMPLES
       /usr/local/etc/cfsd
	      invokes cfs (in /etc/rc)

       /etc/mount -o port=3049,intr localhost:/ /crypt
	      mounts cfs on /crypt (in /etc/rc)

FILES
       /crypt cfs mount point

       /etc/exports
	      exported file systems

SEE ALSO
       cattach(1), cdetach(1), mountd(8), mount(8)

BUGS
       cfsd is single threaded, which  means  it  doesn't  handle
       lots of simultanious operations very well.  In particular,
       it is not possible to recursively attach encrypted  direc-
       tories, since that would lead to a deadlock.
