DisOrder ======== This program is used to play random and chosen tracks from a collection of digital audio files (for instance MP3 and OGG files). If you just set it going it plays random tracks from your collection, but you can also ask for specific tracks to be played, either via a command line program or a web interface, and you can 'scratch' the current track. See CHANGES for details of recent changes to DisOrder. Currently it only runs on Linux. It could probably be ported to other UNIX variants in some cases without too much effort. Things you will need: Build dependencies: Name Tested Notes libdb 4.3.21 4.2 and earlier won't work libgc 6.3 libvorbisfile 1.0.1 libpcre 4.5 need UTF-8 support libmad 0.15.1b libgcrypt 1.2.0 libao 0.8.6 libasound 1.0.8 Python 2.3 (optional) GNU C 3.3, 3.4 "Tested" means I've built against that version; earlier or later versions will often work too. Runtime dependencies: * Players: + ogg123 and mpg321 work for me, but you could potentially use others. * Web server: + Apache 1.3.x works for me, but anything that supports CGI and authentication should be suitable. Development dependencies (only developers will need these): Automake 1.9.4 AM_PATH_PYTHON not good enough in 1.7 Autoconf 2.59 Libtool 1.5.6 1.4 not good enough Bazaar (bzr) On Debian you might ensure you have the required packages as follows: apt-get install gcc libc-dev automake autoconf libtool libgtk2.0-dev \ libgc-dev libgcrypt-dev libpcre3-dev libvorbis-dev \ libao-dev libmad0-dev libasound2-dev libdb-dev Mailing lists: http://www.chiark.greenend.org.uk/mailman/listinfo/sgo-software-discuss - discussion of DisOrder (and other software), bug reports, etc http://www.chiark.greenend.org.uk/mailman/listinfo/sgo-software-announce - announcements of new versions of DisOrder Installation ============ "This place'd be a paradise tomorrow, if every department had a supervisor with a machine-gun" NOTE: If you are upgrading from an earlier version, see README.upgrades. 1. Build the software. Do something like this: ./configure --sysconfdir=/etc --localstatedir=/var make See INSTALL for more details about driving configure. The precise set of options you pass to configure is up to you, if you like configuration being in /usr/local/etc or wherever then that should work. If you only want to build a subset of DisOrder, specify one or more of the following options: --without-server Don't build server or web interface --without-gtk Don't build GTK+ client (Disobedience) --without-python Don't build Python support See README.client for setting up a standalone client. 2. Install it. Most of the installation is done via the install target: make installdirs install The CGI interface has to be installed separately, and you must use Libtool to install it. For instance: ./libtool --mode=install install -m 755 progs/disorder.cgi /usr/local/lib/cgi-bin/disorder Depending on how your system is configured you may need to link the disorder libao driver into the right directory: ln -s /usr/local/lib/ao/plugins-2/libdisorder.so /usr/lib/ao/plugins-2/. 3. Create a 'jukebox' user and group, with the jukebox group being the default group of the jukebox user. The server will run as this user and group. Check that this user can read your music files and write to the audio device, e.g. by playing a track. The exact name doesn't matter, it could be 'jukebox' or 'disorder' or 'fred' or whatever. Do not use a general-purpose user or group, you must create ones specifically for DisOrder. 4. Create /etc/disorder/config. Start from examples/config.sample and adapt it to your own requirements. In particular, you should: * edit the 'player' commands to reflect the software you have installed. * edit the 'collection' command to identify the location(s) of your own digital audio files. These commands also specify the encoding of filenames, which you should be sure to get right as recovery from an error here can be painful (see BUGS). * edit the 'scratch' commands to supply scratch sounds (or delete them if you don't want any). * edit the 'trust' command to reflect the user the web interface will eventually run as. * edit the 'url' command to give the URL of the web interface. * add or remove 'stopword' entries as necessary (these words won't take part in track name searches from the web interface). See disorder_config(5) for more details. See README.raw for details on setting up "raw format" players, which allow for pausing and gapless play. 5. Create /etc/disorder/config.private. This should be readable only by the jukebox group: touch /etc/disorder/config.private chown root:jukebox /etc/disorder/config.private chmod 640 /etc/disorder/config.private Set up a username and password for root, for example with line like this: allow root somepassword Use (for instance) pwgen(1) to create the password. DO NOT use your root password - this is a password to give root access to the server, not to give access to the root login. See disorderd(8) and disorder_config(5) for more details. 6. Make sure the server is started at boot time. On many Linux systems, examples/disorder.init should be more or less suitable; install it in /etc/init.d, adapting it as necessary, and make appropriate links from /etc/rc[0-6].d. If you have a BSD style init then you are on your own. 7. Make sure the state directory (/var/disorder or /usr/local/var/disorder or as determined by configure) exists and is writable by the jukebox user. mkdir -m 755 /var/disorder chown disorder:root /var/disorder 8. Start the server, for instance: /etc/init.d/disorder start By default disorderd logs to daemon.*; check your syslog.conf to see where this ends up and look for log messages from disorderd there. If it didn't start up correctly there should be an error message. Correct the problem and try again. 9. After a minute it should start to play something. Try scratching it, as any of the users you set up in step 5: disorder scratch The track should stop playing, and (if you set any up) a scratch sound play. 10. Add any other users you want to config.private. Each user's password should be stored in a file in their home directory, ~/.disorder/passwd, which should be readable only by them, and should take the form of a single line: password MYPASSWORD (root doesn't need this as the client can read it out of config.private when running as root.) Note that the server must be reloaded (e.g. by 'disorder reconfigure') when new users are added. Alternatively the administrator can create /etc/disorder/config.USERNAME containing the same thing as above. It can either be owned by the user and mode 400, or owned by root and the user's group (if you have per-user groups) and mode 440. You can use 'disorder authorize' to automatically pick passwords and create these files. 11. Optionally source completion.bash from /etc/profile or similar, for example: . /usr/local/share/disorder/completion.bash This provides completion over disorder command and option names. Web Interface ============= "Thought I was a gonner baby, but I'm bullet proof" These instructions assumes you are using Apache 1.3.x. You need to configure a number of things to make this work: 1. If you want to have a 'jukebox' virtual host, modify the DNS (or hosts file if you are somehow reading this in the 1980s) accordingly and use a fragment such as this one: DocumentRoot /home/jukebox/public_html ServerName jukebox.DOMAIN ServerAlias jukebox ServerAdmin webmaster@DOMAIN ErrorLog /var/log/apache/jukebox/error.log TransferLog /var/log/apache/jukebox/access.log Alias /static/ /usr/local/share/disorder/static/ /static/ should point to the 'static' directory installed by DisOrder. If you don't want to use the name 'static' then you can change the url.static label in the web interface configuration to your preferred URL; see disorder_config(5) for details. Don't forget to reload Apache after modifying its configuration. Separate logging is not required but I find it convenient. Up to you. 2. disorder.cgi assumes it is subject to access control (and in particular uses the username to report who did what). Here's how I configured Apache, given the above VirtualHost settings: Require valid-user AuthType basic AuthName jukebox AuthUserFile /home/jukebox/http.users Adjust this according to wherever you're going to install disorder.cgi and its expected URL. Don't forget to reload apache after modifying its configuration. If you got it wrong, fix it and restart Apache. 3. Create the password file configured above. Something like this: # htpasswd -b -c /home/jukebox/http.users myusername mypassword Adding password for user myusername # htpasswd -b /home/jukebox/http.users othername otherpass Adding password for user othername 4. The jukebox must be configured to trust the web user. I added the following line to my /etc/disorder/config: trust www-data This might not be the same on your system! You have to specify the user that the CGI script runs as, whatever that is. 5. Install disorder.cgi in an appropriate location. Remember to make it executable. With the above configuration I installed it as ~jukebox/public_html/index.cgi. 6. Give www-data (or whatever user it is) a password and edit /etc/disorder/config.private accordingly. This file should be mode 640 and owned by root:jukebox. The line should look something like this: allow www-data MYPASSWORD After editing the config file, you must make the daemon re-read it: disorder reconfigure 7. Teach www-data its password, by putting it in /etc/disorder/config.www-data. This file should be mode 640 and owned by root:www-data. password MYPASSWORD (You could also use ~www-data/.disorder/passwd for this but on some systems the web server user's home directory is inside the document root, which would have rather unfortunate consequences.) 8. Try it out. You should be asked for a username and password that you configured earlier, and be shown details of what is playing and what other tracks have been configured for future play. 9. Some features take time to start working, for instance those involving reporting the length of tracks. This is because the server starts up as quickly as possible even if the full track data has not yet been gathered; the track data is then calculated in the background. 10. If you run into problems, always look at the appropriate error log; the message you see in your web browser will usually not be sufficient to diagnose the problem all by itself. 11. If you have a huge number of top level directories, then you might find that the 'Choose' page is unreasonably large. If so add the following line to /etc/disorder/options.user: label sidebar.choosewhich choosealpha This will make 'Choose' be a link for each letter of the 26-letter Roman alphabet; follow the link and you just get the directories which start with that letter. The "*" link at the end gives you directories which don't start with a letter. You can copy choosealpha.html to /etc/disorder and edit it to change the set of initial choices to anything that can be expressed with regexps. The regexps must be URL-encoded UTF-8 PCRE regexps.
