DSM-G600, DNS-3xx and NSA-220 Hack Forum

My challenge today was to find a way to stream music from my DNS-321 at home to my work machine.  After a bit of research I came up with using mpd + icecast.  At this point I have:

* mpd installed and running using the config provided earlier in this thread.  My mpd client shows the indexed music is behaving well - shows music, and "plays" the music to /tmp/mpdfifo.

* icecast is installed and running.

* installed http://rs755tl2.rapidshare.com/files/25 … -0.15b.tgz

* installed http://rs213tl3.rapidshare.com/files/25 … -0.1.7.tgz

Here's the problem.  Changed audio_output to output to icecast:

audio_output {
type "shout"
name "Stream short description"
host "localhost"
port "8000"
mount "/mpd.ogg"
password "hackme"
quality "5.0"
format "44100:16:2"
}

Restarted mpd.  Noted through icecast log files that it gets called through mpd:

127.0.0.1 - - [25/May/2010:16:45:44 -0700] "SOURCE /mpd.ogg HTTP/1.0" 200 19 "-"                                                                      
"MPD" 1

However, as soon as mpd shows the "decoder" line below - I get a nice juicy segmentation fault:

root@BlackRoom:/opt/etc# ../bin/mpd --stdout --no-daemon mpd.conf
listen: binding to any address
listen: binding to socket address [::]:6600
listen: binding to socket address 0.0.0.0:6600

state_file: Saving state file
database: get song: test.mp3
playlist: play 0:"test.mp3"
decoder: audio_format=44100:24:2, seekable=true
Segmentation fault

This looks to be very close to working, but I've reached the end of debugging abilities.  Kai/Anyone - can you help with this?  I'll write this up for others if we can get it working...

Here are my config files:

mpd.conf

# An example configuration file for MPD
# See the mpd.conf man page for a more detailed description of each parameter.


# Files and directories #######################################################
#
# This setting controls the top directory which MPD will search to discover the
# available audio files and add them to the daemon's online database. This 
# setting defaults to the XDG directory, otherwise the music directory will be
# be disabled and audio files will only be accepted over ipc socket (using
# file:// protocol) or streaming files over an accepted protocol.
#
music_directory        "/mnt/HD_a2/Audio/Other\ Music/"
#
# This setting sets the MPD internal playlist directory. The purpose of this
# directory is storage for playlists created by MPD. The server will use 
# playlist files not created by the server but only if they are in the MPD
# format. This setting defaults to playlist saving being disabled.
#
playlist_directory        "~/.mpd/playlists"
#
# This setting sets the location of the MPD database. This file is used to
# load the database at server start up and store the database while the 
# server is not up. This setting defaults to disabled which will allow
# MPD to accept files over ipc socket (using file:// protocol) or streaming
# files over an accepted protocol.
#
db_file            "~/.mpd/database"
# 
# These settings are the locations for the daemon log files for the daemon.
# These logs are great for troubleshooting, depending on your log_level
# settings.
#
# The special value "syslog" makes MPD use the local syslog daemon. This
# setting defaults to logging to syslog, otherwise logging is disabled.
#
log_file            "~/.mpd/log"
#
# This setting sets the location of the file which stores the process ID
# for use of mpd --kill and some init scripts. This setting is disabled by
# default and the pid file will not be stored.
#
pid_file            "~/.mpd/pid"
#
# This setting sets the location of the file which contains information about
# most variables to get MPD back into the same general shape it was in before
# it was brought down. This setting is disabled by default and the server 
# state will be reset on server start up.
#
state_file            "~/.mpd/state"
#
###############################################################################


# General music daemon options ################################################
#
# This setting specifies the user that MPD will run as. MPD should never run as
# root and you may use this setting to make MPD change its user ID after
# initialization. This setting is disabled by default and MPD is run as the
# current user.
#
user                "nobody"
#
# This setting sets the address for the daemon to listen on. Careful attention
# should be paid if this is assigned to anything other then the default, any.
# This setting can deny access to control of the daemon.

# This setting is the TCP port that is desired for the daemon to get assigned
# to.
#
port                "6600"
#
# This setting controls the type of information which is logged. Available 
# setting arguments are "default", "secure" or "verbose". The "verbose" setting
# argument is recommended for troubleshooting, though can quickly stretch
# available resources on limited hardware storage.
#
log_level            "verbose"
#
# If you have a problem with your MP3s ending abruptly it is recommended that 
# you set this argument to "no" to attempt to fix the problem. If this solves
# the problem, it is highly recommended to fix the MP3 files with vbrfix
# (available from <http://www.willwap.co.uk/Programs/vbrfix.php>), at which
# point gapless MP3 playback can be enabled.
#
gapless_mp3_playback            "yes"
#
# This setting enables MPD to create playlists in a format usable by other
# music players.
#
save_absolute_paths_in_playlists    "no"
#
# This setting defines a list of tag types that will be extracted during the 
# audio file discovery process. Optionally, 'comment' can be added to this
# list.

# symbolic links outside of the configured music_directory.
#
follow_outside_symlinks    "yes"
#
# If this setting is set to "yes", MPD will discover audio files by following
# symbolic links inside of the configured music_directory.

@Elgrande

My understanding is that the CH#MNAS is identical to the DNS-323.  I belive Kai is running the same.  So yes.

Also optware is safe.  Follow the howto in the wiki.

this is a very simple question so please forgive me but how do I point the mpd to my music directory? is this done through the telnet session or do I need to open a file and edit the text through a windows text editor?

Same question for creating a startup file....  Do I do this through a telnet session or through notepad and just save it to the proper directory on the nas?  I'm a beginner with all this stuff so again please forgive me.

Yeah, I never really trust doing stuff outside a telnet/ssh session but I think it has at least worked using Gedit on linux and placing the file over the network.  I'm always unsure on the whole rights thing so find it less stress to do it via telnet.  Although I would tend to get Nano on there so I don't have to use 'vi' cos I've forgotten the commands

Pretty sure there was some samba issue for a while using my mac, saving wasn't working or something.  Anyway, now I'm rambling.

and just to RE-clarify...  I am not well versed in linux so I don't know the commands and I don't know how to edit files.  I DO know that you aren't supposed to use a windows text editor like notepad to edit a linux text file though.

now i see that i have to take off some of the # signs to initiate the code.  When I take them off for the music directory, playlist directory and log directory and then run the command to create the database it says can not find all of those files.  How would I go about creating them?


It is also referencing the folders as /home/root/FOLDERNAME.  By deault it looks like this "~/music" which makes it think it's /home/root/music.  My music folder is called Music and is in the root (volume_1) directory.  Any ideas?

You need to set the correct music folder. 

I always get confused about root folders so have put the full path in I think.

Likely to be :

/mnt/HD_a2/Volume_1/SOME_FOLDER_NAME

This is as the hard disk is always mounted as HD_a2 for the first disk and errrr a4? or something for the second.

I can send you a copy of my mpd.conf later tonight (copenhagen time) to help.

Looks like you are working it out though, good stuff   Took me a fair while and trial and error.  Also with mp3's which mpd couldnt cope with.

Haim

In a telnet session, do:

ls -l /

(the -l is a dash followed by a lower case L)

Mine has:

drwxrwxrwt  3 root root    1024 Sep 22 09:40 tmp

The 10 chars at the start are probably different for you.

In my fun_plug, I have the command:

# fix /tmp permissions
chmod 1777 /tmp

Apparently, when the DNS boots up and makes the /tmp directory it doesn't set the permissions on the directory so that foreign programs like mpd can work.  (Remember, we're hacking the DNS and making it do things that were not originally intended.)

The above command in the fun_plug fixes up the permissions.  You should probably add it to yours.

However, I would strongly advise that you set up the mpd configuration so that it puts its temporary files on your harddisk and not in the ramdisk filesystem.  This is because everything in places like /, /etc, /tmp and so on are actually stored in a small amount of memory and not a large disk.  This memory is not large and can easily fill up.  So, if your mpd config file has an option to specify a TMP_DIR or some other "work" directory, it would be wise to create a folder like "/mnt/HD_a2/mpd_files" and set its permissions to 777.  Then modify the config file to point to this folder.

If you don't do this and mpd writes files that take up too much space in /tmp, the ramdisk filesystem will fill up and you'll be left with quite a puzzle.

I don't know much about mpd, so you'll have to read the wiki and dig into it a bit.

Just in case it's useful, here is my mpd.conf

#
audio_output {
    type        "fifo"
    name        "AppleExpress"
#    command        "aplay -f cd 2>/dev/null"
## Or if you're want to use AudioCompress
#    command        "AudioCompress -m | aplay -f cd 2>/dev/null"
## Or to send raw PCM stream through PCM:

# Volume control mixer ########################################################
#
# These are the global volume control settings. By default, this setting will
# be detected to the available audio output device, with preference going to
# hardware mixing. Hardware and software mixers for individual audio_output
# sections cannot yet be mixed.
#
# An example for controlling an ALSA, OSS or Pulseaudio mixer; If this
# setting is used other sound applications will be affected by the volume
# being controlled by MPD.
#
#mixer_type            "hardware"

#replaygain            "album"
#
# This setting sets the pre-amp used for files that have ReplayGain tags. By
# default this setting is disabled.
#
#replaygain_preamp        "0"
#
# This setting enables on-the-fly normalization volume adjustment. This will
# result in the volume of all playing audio to be adjusted so the output has
# equal "loudness". This setting is disabled by default.
#
#volume_normalization        "no"
#
###############################################################################


# MPD Internal Buffering ######################################################
#
# This setting adjusts the size of internal decoded audio buffering. Changing
# this may have undesired effects. Don't change this if you don't know what you
# are doing.
#
#audio_buffer_size        "2048"
#
# This setting controls the percentage of the buffer which is filled before
# beginning to play. Increasing this reduces the chance of audio file skipping,
# at the cost of increased time prior to audio playback.
#
#buffer_before_play        "10%"
#
###############################################################################


# Resource Limitations ########################################################
#
# These settings are various limitations to prevent MPD from using too many
# resources. Generally, these settings should be minimized to prevent security
# risks, depending on the operating resources.
#
#connection_timeout        "60"
#max_connections        "10"
#max_playlist_length        "16384"

now i get an error that says failed to load database: database corupted.  I created a file called database in /mnt/HD_a2/ using the vi commnad.  Is there anything that i need to copy into the file contents to get it to work correctly?

I don't think that you need to create that file.  I don't think that you even could create that file.  The daemon usually creates it.  Try deleting the file and trying the "create db" command that you mentioned in this thread.  Make sure you delete the file referred to by the db_file setting in the config file.

I did that and when i try to creat the db using the command it says opt/var/lib/mpd/mpd.pid is not an absolute path
