PERFUSED(8)						    BSD System Manager's Manual 					       PERFUSED(8)

NAME

     perfused -- PUFFS Enabled Relay to FUSE Daemon

SYNOPSIS

     perfused [-fs] [-d types] [-i -fd]

DESCRIPTION

     perfused is a userland daemon implementing the FUSE kernel level API.  It creates a /dev/fuse socket for FUSE file system daemons to connect
     to.  perfused takes care of mounting the file system using puffs(3).

     When the kernel sends a puffs(3) operation for the mounted file system, perfused will translate it into a FUSE request, and will send it to
     the file system daemon through /dev/fuse.	The FUSE reply will be converted back into a puffs(3) reply and will be relayed to the kernel.

     FUSE file system daemons must be modified so that they request perfused to perform the mount(2) system call instead of doing it on their own.
     This is done by replacing mount(2) and the open(2) calls for /dev/fuse with perfuse_mount() and perfuse_open(), respectively, in their
     sources.  libperfuse(3) must be used at link time.  Most FUSE file system daemons use libfuse and will work unmodified, provided the modifi-
     cation is done in libfuse itself .

     The following options are available:

     -d types	 Print additional debug information.  types is a comma-separated list of information types to print:

		 puffs	 Display PUFFS requests and replies.

		 fuse	 Display FUSE requests and replies.

		 dump	 Dump content of FUSE frames.

		 fh	 Display file handle activity.

		 reclaim
			 Display reclaim activity.

		 readdir
			 Display readdir activity.

		 requeue
			 Display requeue activity.

		 sync	 Display dirty flags and sync operations.

     -f 	 Do not fork, but stay in the foreground.

     -i fd	 Do not open /dev/fuse but use the socket available from the file descriptor fd.  This is used when perfused is started from
		 libperfuse(3).

     -s 	 Enable debug output only when receiving SIGINFO.

SIGNALS

     SIGINFO
	     If the -s flag was used, toggle debug output.  Do nothing otherwise.

     SIGUSR1
	     Toggle FUSE operation dump on and off.  When toggling off, the trace is is stored in /var/run/perfuse-xxx.trace (xxx is the filesys-
	     tem mount point).

ERRORS

     The program logs to the syslog daemon as facility ``daemon''.  For detailed debugging use the -d (debug) option.

SEE ALSO

     mount(2), perfuse_mount(3), puffs(4)

AUTHORS

     The program was written by Emmanuel Dreyfus <manu@NetBSD.org>.

BUGS

     When perfused runs in the foreground (using the -f flag), some processes using the FUSE file system will sometime hang on 'uvn_fp2'.

NAME

       djmount - file system client for mounting network media servers

SYNOPSIS

       djmount [options] mountpoint

DESCRIPTION

       This manual page describes briefly the djmount command.

       This  package provides a client for Universal Plug'n'Play (UPnP) Audio-Visual MediaServers.  It discovers all compatible UPnP AV devices on
       the network automatically and mounts their media content as a file system using FUSE.

OPTIONS

       This program follows the usual GNU command line syntax, with long options starting with two dashes (`-').  A summary of options is included
       below.  For a complete description, see the Info files.

       -d[levels]
	      enable debug output (implies -f)

       -f     foreground operation (default: daemonized)

       -h, --help
	      print this help, then exit

       --version
	      print version number, then exit

       -o [options]
	      mount options (see below)

       Mount options (one or more comma separated options):

	       iocharset=<charset>    filenames encoding (default: from environment)
	       playlists	      use playlists for AV files, instead of plain files
	       search_history=<size>  number of remembered searches (default: 100)
				      (set to 0 to disable search)

       See FUSE documentation for the following mount options:

	       default_permissions    enable permission checking by kernel
	       allow_other	      allow access to other users
	       allow_root	      allow access to root
	       kernel_cache	      cache files in kernel
	       nonempty 	      allow mounts over non-empty file/dir
	       fsname=NAME	      set filesystem name in mtab

       Debug levels are one or more comma separated words:

	       upnperr, upnpall: increasing level of UPnP traces
	       error, warn, info, debug: increasing level of djmount traces
	       fuse: activates FUSE traces
	       leak, leakfull: enable talloc leak reports at exit
	       '-d' alone defaults to 'upnpall, debug, fuse, leak' which is all traces.
