NAME
       cfsd - cryptographic file system	daemon

SYNOPSIS
       cfsd [port]

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	listens	on the CFS port	(ordinarily port 3049)
       on the localhost	interface.

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

       cfsd  should  ordinarily	 be  invoked  at  boot	time   from   /usr/lo-
       cal/etc/rc.d/cfsd.sh  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/rc.d/cfsd.sh
	      starts cfsd (from	/etc/rc)

       /sbin/mount -o port=3049,intr,nfsv2 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	simul-
       tanious operations very well.  In particular, it	is not possible	to re-
       cursively  attach  encrypted  directories,  since  that would lead to a
       deadlock.
